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

G'day everyone. Does anyone have experience in repainting the plastics ie tank/side covers etc? I was told by a local dealer that you can't repaint the tank because of the type of plastic from which it is made. Is this correct?

It was pointed out to me that my forks appear to have been dropped through the yolks leaving about 2.5-3 cm of the top of the fork tubes exposed.
