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.

I just ordered the Moose Racing standard seat cover. Right on the package it says TTR250. But when I pulled it out and quickly threw it over the seat, it didn't seem like it was the right cut.

Hi there. Wonder if someone can help me. The TTR has failed its MOT test on suspension bearing play.

Here's a pic of my last oil filter. It has bits in it, which I suppose means it did the job but I'll admit to being a bit horrified. Most are black but a few are metallic.
