The guy at the shop told me I shouldnt use them because it dust and dirt can build up inside them. Sure enough when we took them off the was about 3mm of dirt built up around my seals and the sides of the fabric were caked too. Luckily the coating on my fork tubes werent scratched."

Fastway Counter Shaft Spacer Fastway Counter Shaft Spacer Fastway Counter Shaft Spacer Valued Customer (Newaygo Co. Michigan, USA) Spacer "This item is a spacer.

It is the second one that I have bought and had the same issue with both. Worked better on my 05 Yamaha YZ than on my 07 CFR450R. The 05 YZ had a large nut V.S. the small bolt on my CRF. The first time it came loose I thought thought that maybe I forgot to torque the bolt down, so I cranked it down hard, still came loose."

What a pain getting the bike out on a Saturday afternoon. This sprocket had less than 5 hours on it. I personally will not buy this brand again. It will take a week for my legs to recover from pushing."

This is the thickest inner tube I have ever installed in a tire. It's a lot of tube to shove into the tire. I have no worries of sand wearing a hole in this tube. It is EXTREAM!!! Will make you sweat putting installing it. But having a flat will make you sweat more."
