On my last ride the bike sounded a little more 'grindy' than usual when starting up. I figured my sprag clutch was failing as it's been clunking a little louder, but when I pulled the cover I found the starter shaft is missing a few teeth. The idler gear is missing one too. The sprag clutch spins freely an...

Hey guys. I acquired my 03 TTR 5 years ago from a friend who bought it new, but hardly ever rode, cleaned, or maintained it. I ride it hard, and always do a good job of changing the oil and filter, cleaning the air filter, and I clean my carb about once per year. But the bike has never had any major maintenance...

Hi guys, just putting a new piston in and noticed it has and arrow on the top of it. Assuming looking at the different size molded indents and the valves that this arrow should point forwards (towards the front of the bike) but some quick clarification would be great. Thanks
