Thanks for the replies lads.
I'm having a bad experiance with the jtx at the moment. My clutch has completley siezed, i put it into first and the bike took off into my garden fence. I also noticed theres a mashed sump bolt on there and there was no airfilter in the airbox. And to top that, my airbox was melted back togeather from the inside. I spent out 40 on a new airbox, 10 on a sump bolt (allen type) 8 quid on a air filter, now i have to strip my clutch.
i give 600 for her, 97 model. it feels like a good buy bad buy at the moment.
