I know it's a common issue, the wearing of the front brake hose where it rubs on the guides. I was wondering if replacing the front hose with a metal braided one would resolve the issue? I know the HEL or Venhill ones are still plastic coated over the braid, so I guess this might still wear through, but on...

Hello people. I was going to adjust the chain on my newly bought 2003 TTR but thought that it may in fact be worn beyond repair. I measured the 10 link distance as recommended in the manual, which suggest a wear limit of 150.1mm. It was pretty much 151mm. But then I read that someone elsewhere (I can't reme...

I'm looking for a 2nd rim so I can always have two sets of tires ready to roll (one for mud and one for rocks). There are very few used TTR rims available on ebay because it's such a rare bike. Is the TTR rim interchangeable with any other bike rim, like a YZ?

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
