I have a 93OE and the manual I have is for later model, which does show a gasket. if necessary I can dump the oil and reuse but if possible would prefer not too. This techni...

My TTR is standard but i have a new FMF Powercore (with db killer) , it came with the bike. I'm thinking of fitting it and opening up the airbox and fitting jets to suit. Maybe i'll also get the short header pipe. I'll still run it in standard form for the next few months before deciding to do the mods. So,...

Hi all. I bought a new old stock TTR250 from a dealer in the UK back in 2007 and had it delivered to my home in Spain. I think it is a 2006 model year, maybe 2005. I rode the bike for 66 miles and changed the oil and filter and then put it on a lift stand in the garage where it has remained for the last 7 years. I di...

I helped my brother Trev with a couple of jobs on his TTR this morning. Firstly we swapped out his shock for an eBay item that I had tested. My testing is quite simple.
