Strip
I removed many unwanted parts, including the buddy pegs, side panels, fuel tank side panels, turn signals, reflectors, mirrors, and heat shields.
I made some Kydex covers for the exposed electrics. |
I replaced the large, relatively heavy taillight assembly and brace with a light-weight Baja Designs LED taillight. The license plate bolts onto the flat surface; I used a plastic backing plate because the license plate is wider than the BD assembly.
Taillight, BD, LED Dropdown - about $60. Baja Designs |

I installed a set of STR fork bleed valves. STR does not make bleeders for the TE, so I took a chance and ordered the KTM bleeders. They installed and worked perfectly; no oil leaks and the air bleeds when I push the buttons. I used the smaller o-rings that were already on the bleed valves; the larger o-rings were not used. You can get the KTM bleed valves in polished, black, and orange (YUK). The polished ones match the fork tops nicely. Speed Bleed Valves KTM-all models - about $35. System Tech Racing |
Front sprocket I replaced the 15 tooth front sprocket with a smaller 14 tooth sprocket made by PBI. It weighed more than the stock very-holey Husky sprocket.
Mirror I installed a bicycle rear-view mirror on the left side of the handlebars. |
|
Problems I found and corrected a few minor problems during the setup and strip days. Two out of four airbox cover screws were finger tight only. Two out of ten 6mm left side engine/tranny bolts were loose. The rear brake hose makes a bend to the left and down as it leaves the master cylinder and travels down the swingarm. The bend in the hose was touching the transmission. I cracked the hydraulic brake-light switch bolt just a tinch and twisted the brake hose to the right, then tightened the switch bolt back down. That looked and felt good. |
The left side lower radiator shroud mounting bolt was cross-threaded and I replaced it and the ruined captive nut. Two bolts in the rear frame and fender area were cross-threaded. Four shouldered spacers were incorrectly inserted into the fender mounting holes and partially crushed and deformed the hole edge and nearby fender. Two larger shouldered spacers were incorrectly installed on the turn signal wires and were hanging in the breeze. They should have been mounted from the outside of the fender. The locking ring on the ignition key mount was loose. The dealer happily replaced a marred left-side plastic cover. |

I talked to Jeff at Hall's Cycles on March 28 about the Leo Vince X3 muffler, and he said his information was that it would fit the '08 TE610. So, I ordered one. UPS delivered a huge box on April 2; not counting the weekend, that's three days shipping time! It was fun to unpack the box and all the bags inside and to read all the Italian instructions (English also). It looked to be pretty straightforward, so I started right in. Several hours later, I was all but finished. It was too late to ride, so I left it alone in the garage overnight. I did have a peek before going to bed; it sure looks purty. Continues --> |
I took the TE out for an installation lap (a la F1). There was one Harley pop on the overrun during the first shift from 2nd to 3rd, but, after that, there were no further shenanigans. The engine pulls a bit stronger in the mid-range; I was unable to test full throttle because I was riding on 35 MPH limit county roads. Later today, I'll take it out to the dirt. The LV is definitely louder than the stock muffler, throatier is what I'd say. It's also louder as you rev out in the mid-range. I hope this does not become annoying when dirt riding. |

Installation
The X3 weighs 2 lbs 3.2 oz less than the stock muffler, all fittings included on both. The X3 is 3 1/2 inches shorter than the stock muffler. That's about $158/lb or $99/inch. Despite one minor problem, the installation went well. The X3 mounts to the stock muffler mounts using carbon fiber straps. The problem arose during the initial fit while I was installing the bolts finger tight only. The rear carbon fiber strap passed over the Leo Vince decal. For a normal decal, this would not be a problem, but this decal is about 1/16" thick and would cause the carbon fiber strap to bend as it passed over the decal. Sharp bends in carbon fiber are not recommended. Besides, I didn't want the decal covered. I called Leo Vince USA and was told that the decal could be peeled off with no harmful effects. Well, I didn't want to peel the decal off, so I had a peek into the front connector pipe and found a minor problem. When the pipe was welded to the main body, a small bump developed on the lower circumference of the joint, probably from deformation during welding. I could see where someone had used a grinder to remove part of the bump, but there was still too much left. So, I used my grinder to take off a very small amount of additional material. The muffler then mounted further onto the main exhaust pipe, and the carbon strap just cleared the decal. |
Be careful mounting the carbon fiber straps. First off, they will scratch the aluminum, so don't slide them back and forth on the muffler body, or you'll be very disappointed to see scratches. Next, make sure the straps are correctly oriented on the muffler body. The muffler is flat on the top and bottom, and the straps are flat where they mate there. You should gently rock the straps towards and away from you to get them to seat just right. I used a thin aluminum spacer on the front mount and a thick spacer on the rear mount; these are supplied in the X3 kit. The spacers fit over the small cylindrical guides that stick out from the TE sub-frame. Kewl. I installed the US small-diameter insert in the end of the muffler and the USFS approved spark arrester screen as well. The gasket went on next, then the end cap. The four end cap bolts were exactly the right length to clamp everything down (I measured). I noticed the end cap bolts had anti-seize on them, and I followed suit by putting anti-seize on the muffler band bolt and the carbon fiber strap mount bolts. Don't forget to peel the wimpy plastic decal from the back of the muffler before starting up the first time. Heat will melt it, and it stinks. Don't ask me how I know. Leo Vince X3 muffler - about $348. Hall's Cycles |
Leo Vince X3 Muffler SOLD
After two rides for a total of 73 miles, I decided to sell the Leo Vince X3 muffler. It's too loud for my taste. A rider in CA bought the X3; he'll be showin it off soon, see if you can spot him.

I installed a Pirelli MT43 trials tire on the back wheel. I plan to ride my TE610 mostly on the dirt (95%), riding on blacktop when I have to (5% or less). The stock Metzeler Karoo is very squirreley in the dirt, so I decided to switch to the MT43. This tire is DOT approved and rated "Load Range B" and speed rated "P" (up to 90 MPH ouch!). Despite it's road rating, the MT43 works very good in the dirt and on rocks. It hooks up great as long as you go easy on the throttle (harder than it sounds). I installed two rim locks. On my test ride with only the MT43 installed, I could easily negotiate some rocky sections that I had been having trouble with before. The tire circumference of the MT43 is smaller than the Karoo; 81.5" MT43 vs 83.5" Karoo. This is about a 2.4% reduction which is equivalent to adding a tooth to the rear sprocket (45→46 2.2%), so I can now go a bit slower in the technical stuff. I'll monitor it's performance and report later. Pirelli MT43 trials tire - about $61. American Motorcycle Tire/AMT |

I wanted to install a front Pirelli MT43 to match the rear, but my tire source doesn't sell them. So I got the street version of the IRC TR-11 trials tire - the TR1. I'm hoping it will last as long as the rear MT43. This tire has the same "P" speed rating as the MT43. I installed one rim lock. On my test ride with both front and rear trials tires installed, I was able to get around in the rocks even better than with just the rear MT43 installed. The trials front allowed me to get out of the gravel and rollers and up onto slab rock with the greatest of ease. Turns at corners were more precise and sure footed. I'm really looking forward to having the suspension shortened; the TE may be trail worthy! IRC TR-1 street tire - about $33. American Motorcycle Tire/AMT |

I did a check on the most recent full tank of riding: 186 miles used 3.1 gal (11.8 Lit.) giving 60 MPG.

More fork mods After riding about 500 miles with the shortened forks, I decided that the damping was too harsh and so I called Les at LT-Racing to ask for advice. Les would normally ask that a rider send his suspension to the shop where Les would perform his magic and then return the suspension to be put back on the bike and enjoyed. I did not want that amount of down time, so I was looking for a spring change that I could perform quickly and easily. Les advised me and we decided on new .46 fork springs to replace the .stock 50s and a new 5.8 shock spring to replace the stock 6.4 spring.
First, I assembled the adjustable compression dampers, base valves, and shims. The Marzocchi part number on each bag was 717096/R; don't know the Husky part number.
|
I used Amsoil 10 wt suspension fluid at 100mm from the top to start with. After an 80 mile ride, and fiddling with the damping adjusters, I decided a lighter weight fluid and more air space would work better (I had advice from Les). I replaced the 10 wt with 5 wt and dropped the level to 120mm. On the follow-up ride, the lighter weight fluid worked very good. The fluid height seems to be right on; I didn't bottom the forks, and got about 90% of max stroke on the very rough stuff. Once I was happy with the forks, I then replaced the shock spring and set out for another test ride. The rear-end worked great with no further adjustment needed. Note: I removed the swingarm to get the shock out and in - far easier than it sounds. I am not a suspension expert, nor even very knowledgeable, but with Les' advice and the 45 Zoke service manual handy, I had no trouble putting everything together and making adjustments. For many riders, sending the suspension off and having everything done for you is an attractive option. For those like me, being able to do your own work is very satisfying. I highly recommend Les at LT-Racing. He knows his stuff and will work with you to get the setup you want. I'm very happy with the suspension and my wrists are thanking me. It was 'neat' to lay on the ground and adjust the fork compression dampers while stopped on the trail. While others may not find the need to do this, I fiddle too much to not have this 'feature'. I'm sure I won't be adjusting the forks very often once I get them dialed in to perfection, but it's nice to know that I can adjust for differing terrain as needed.

I swapped out the stock fat bars for some Pro Taper standard 7/8 bars in a bend I like and I added new Spider grips (dual density rubber). I installed Tusk handguards at the same time. On the crossbar went my Garmin 60 CSx cradle cushioned by a layer of sorbothane between two mounting plates of Kydex. The new trials front tire has a much smaller circumference than the stock Karoo and despite reading about the adjustable-for-tire-size stock odometer in my Owner's Manual and in online forums, I was never able to change the circumference setting. That and the inability to change the display while moving prompted me to install the Trail Tech Endurance computer/odometer you see in the pictures. Pro Taper handlebars - about $59.

![]() I swapped the starter button/run button assembly to the left side of the handlebars while making all of these changes. I like to twist the throttle while pushing the starter button and I find it very difficult to do this when they are both on the right side. A new smaller light switch sits inboard, out of the way so I won't bump it while riding on technical routes. Also note the tank bag and rear fender bag that I've been using for a month or so. I put tools and extra gloves in the tank bag and an MSR Pak Jak in the rear fender bag. The tank bag is retained by nylon web straps that mount to existing holes on the fuel tank; I installed brass grommets in the ends of the straps. The rear fender bag is securely fastened by running the front straps through slots cut in the fender rather than using the fender clips. I use the fender clips on the rear straps. Tank bag (MSR Roost Pak) - about $21. Rocky Mountain ATV/MC |

I swapped out the stock rear sprocket for a Stealth Tri-Metal sprocket one tooth larger (46). Now I can ride some easy TST (tight single-track trail). I rode some of the Rainbow Tr and the gearing works great. The only drawback is the original sprocket weighs 287g and the tri-metal weighs 691g, a 404g increase. Ouch! Stealth Tri-Metal sprocket - about $75. Sprocket Center |
It's time to find out how much my gearing has changed from stock. So far, I've done the following:
The total reduction is about 11%. Although this reduces the top end speed somewhat, the ability to go slower in first is worth it to me. |

Clutch cable
I read in several forum posts about problems with the clutch cable breaking. Someone mentioned that the cable was not aligned correctly and the inner wire was rubbing on the cable housing causing the cable to fray and eventually break. I had a look at the clutch cable on my TE and sure enough, the cable is misaligned. The picture --> clearly shows the inner wire rubbing on the cable housing. If you look further down the clutch cable, you'll see that it is definitely in line with the closer end; there are no kinks or bends until the first major bend in the distance. I looked at the various parts and saw that the clutch cable mounting bracket is not aligned correctly. I plan to make a bracket that points the clutch cable end directly at the end of the clutch lever arm. I think all I need to do is change the angle of the slot on the mounting base so the cable mounting face is at the correct angle. Stay tuned; pics at 11.

Note: this picture cannot be supersized; it's already at max. |
After I did all of the above, I spent a few minutes thinking about what was going on. The original bracket on my TE610 is different than new brackets being shipped from parts inventory. Not everyone is having clutch cable problems. Could this mean that some TEs have brackets like my TE had and others have the kind being shipped now? It's possible. It's also possible that Husky may ship brackets like the one on my TE originally to fulfill parts orders. If you have a concern about your clutch cable and see that it is misaligned like mine was, then order a new bracket. But inspect it before mounting, and do a check fit before you mount the bracket for good.
The bracket is part number 8000A6101 and costs $2.81 from Hall's. Get two; they're cheap!
BTW, I'm using the stock Husky clutch cable - it works just fine now that the cable is aligned correctly.
Follow-up note: After riding my TE several times with the new bracket installed, I inspected the bracket and clutch cable and noticed something I should have spotted earlier. The clutch arm swings in a shallow arc causing the inner wire to change angle with the outer cable housing as the arm moves through its arc. I rotated the bracket clockwise about half way back to its nominal position and the inner wire now splits the difference in its side to side swing, never touching either side of the outer cable housing. So not very much filing of the left side of the groove is needed; just a tinch to help the alignment. YMMV

During a routine service to check the valves, I had a look at the throttle body, air box, and air boots and came across the vent hose that has the masking tape. The tape apparently helps keep the hose seated in the back of the airbox. How tacky is that (the tape)! I tracked the hose back to where it mounts to a stub on the frame above the engine. Right next to that stub is another stub; this stub has a hose connected to it also and the other end is connected to a vent on the cylinder head. |
Looking around, I spotted another stub down by the tranny and it had a tranny vent hose connected to it. So how does all this work? The cylinder head is vented to the frame and the tranny is vented to the frame. The hose with the masking tape (main vent hose) then carries the fumes from the frame to the airbox. |

The first thing I did was to plug the hole in the back of the airbox with a rubber plug. I added a retaining screw to insure it wouldn't back itself out.

Uni breather filter UP-103 clamp 1/2" - about $13. Chaparral |
I routed the hose horizontally towards the shock area, then found a nice niche for the breather filter to tuck into.
Now there is no hot, oily air going into the throttle body and that has got to be good for performance. |
I plan to make a small box with about a dozed LEDs mounted on the top, each LED to be energized by leads currently going to the stock odometer. When all the functions are transferred, I'll probably remove the stock odometer. This will not be an easy project because you can't just swap leads; some of the functions require some electrical circuitry. Considering my limited electrical knowledge, this may take a while (I'll be asking for help from my more electrically astute friends). For now, the stock odometer stays but the odometer part is disabled; I had to mount the Trail Tech sensor and so I used the stock mounting hole on the brake caliper.
