Have you cleaned your carb,checked all your fuel lines,filters(may be one in the tank also)? I had a simular problem with my 90 Exciter. Seemed I had a pinched or restricted vent line to my fuel tank and it would act up in a manner you describe. You could try next time when you go for a rip, when it starts to act up ,quickly open your fuel cap and see if it makes any difference. If it keeps acting up I would suggest cleaning the carb and jets, replacing all fuel lines and test your compression. [ Next Thread | Previous Thread | Next Message | Previous Message ] |
