I have the Workshop Manual for that bike, It includes loads of fault finding help, Pictures, Part lists & wiring diagrams etc. If you would like a copy email me @ slippery.steve@ntlworld.com

Or look at my small guide I posted @ http://www.howtomendit.com/answers.php?id=143363

Best of luck!

ok heres what u do if u bought it second hand the carb was prob dirty if not cleaned clean it and cheak your jets if they are clean too the its not carberated there will be fuel mix and air mix turn them but dont forget where they are at the min if u can not do this take it 2 your local repair shop and ask them to carborate it wont be expensive around 20 pound
