What is the problem you're experiencing?

Re: Seem to have a restriction

sounds like misfiring then???

Re: Seem to have a restriction
 

defo back fired to day big time then judder like a chicken only get top speed when i rev up slowly

Re: Seem to have a restriction
 

wrong gear? using up-shifting too many gears maybe, using 3rd when it should be 2nd etc... or is this an 'every time' sorta problem not intermittent? (sp?)

Ben.

Edit: SV's back fire quite a lot anyway under deceleration. esp if you have an aftermarket can and no baffle.

you now how to strip and clean the carbs? this is where the problem will be but really you need to wait for spannerman or yc to tell you for sure

Sounds like water in juice or a holed diaphragm, or could be a coil or HT lead breaking down under load.
