Stuff

August 8, 2007 version

I decided I needed a page for all kinds of miscellaneous information that is not bike specific. Almost everything on this page is my opinion, so take it for what it's worth.

Chemicals

I've put the chemicals on their own page, so the Stuff page doesn't get too cluttered. So, go here--> Chemicals.

Lightweight Riding Boots

Sidi makes a very lightweight, water-resistant riding boot - the Discovery. The sole is soft rubber, and you can walk with comfort for those times when you're riding with me and we stop to look at interesting stuff. The Discovery boots are availale from Motonation http://motonation.com  (877-789-4940)  for about $250. I got my pair several years ago when the boot was known by a different name. I ordered a size 10/44, although my shoe size is 8.5 and I usually wear size 9 work boots for riding. When wearing the boots, I wear nylon tube socks under medium-thick riding socks. I needed the larger boot for adequate room and comfort. I don't know if the sizing on my boots is the same as the sizing on the Discovery boots. If you find anything further about sizing, let me know.

No-Spill Gas Can

The small gas tank openings on the new CRFs makes filling the gas tank difficult. A regular gas can spout will almost fill the opening, preventing you from seeing into the already difficult-to-see black interior. I searched the web and found the No-Spill self-venting gas can that uses a 3/4" funnel spout with a thumb button flow control. The spout fits small openings and allows you to easily monitor the gas level in the tank. AIRPARTS, Inc in Kansas City, Kansas has them in their on-line catalog for about $15 for a 2.5 gallon plastic can. Their web site is http://www.airpartsinc.com and their number is 800-800-3229. You can order using a credit card.

Here's the web site for the No-Spill company http://www.no-spill.com  They don't sell the gas cans themselves; you have to buy from a dealer.

 

The last time I visited their web site, I saw that they now have a 5 gallon can.


Note - for those of us in the mountains, make sure you bleed excess air from the can by pushing the thumb button before driving to elevation AND after you arrive at your destination. And also, just before you fill the bike's gas tank. If you don't, gas may spray when you begin filling the gas tank.

Taillight and License Plate Holder

Acerbis makes a very small, lightweight, LED taillight assembly (about $35). There are three wires; taillight, brakelight, and ground, so you can also wire in a hydrailic rear brake light switch that is mounted on the rear master cylinder. The license plate mounting area is a bit narrow, but you can mount a plastic Enduro Engineering License Plate Holder (about $14). This holder is designed to be mounted directly to KTM rear fenders, but it works just fine on the Acerbis taillight assembly. This setup has passed the scrutiny of a few police officers in the Upper Arkansas Valley (CO), so it might pass muster in your area, also.

These parts can be found at some motorcycle shops or check on-line stores (Kevin's Cycle Racing, Chaparral, RockyMountainATV/MC, EnduroEngineering).

Trials Tires

Rear trials tires are radial tube-type and radial tubeless. Rear tire size is 4.00x18.
Front trials tires are bias ply tube-type and radial tubeless. Front tire size is 2.75x21.
Note - Cheng Shin has other sizes also.

For most off-road bikes (not TRIALS bikes), you'll use an inner tube in the front and rear (even for the tubeless tires). Most of the tubeless tires have a stiffer sidewall, so you can use low air pressure and get a good footprint and thus more traction.

The thinking on tubes is to use a heavy duty tube to help avoid pinch flats. Bridgestone makes the heaviest tube - Ultra HD. MSR HD and Moose HD are thinner and lighter than the Bridgestone Ultra HD.

Some riders prefer to use a knobby on the front because they have noticed that front trials tires "roll over" or "roll under" with heavy use of the front end (aggressive riding).

Here is how I set my tires up in April 2006 (for both my CRF230F and CRF250X):

Front - IRC TR-011R Bias-TT 2.75x21 tire and Bridgestone B460 Ultra HD 80/100-21 tube with one rim-lock. 12 lbs air, but others like 6-10.

Rear - IRC TR-011R Radial-TT 4.00R18 tire and Bridgestone B300 Ultra HD 100/100-18 tube with two rim-locks. 12 lbs air, but others like 6-10.

Note that I'm using the IRC tube-type rear tire. I'll be switching to the Dunlop tubeless when the IRCs wear out. I didn't know about the tubeless preference when I first made the switch to trials tires.

There are several 'trials tires on trail bikes' threads in the Trials forum on ThumperTalk.

I will never go back to knobbies!

Here's some info about where to get the tires and tubes that I've found so far. If you have any additional info, drop me a line; my e-ddress is on my home page. Prices as of 8/8/07.
