Hi ive got a e reg kmx 125 for the road i recently removed the washer from the exhaust and have since started to notice a small stutter /flatspot at around the 7k-9k rev range
i can ride through the power drop sometimes but the jerky ness is not nice .
bikes ok if i change gear around 7k and it seems better if i dont open the throttle fully
i allso think my rear shock is knackerd as it is very soft/bouncy with very little resistance in it
i have checked and replaced the airfilter and removed the carb which was clean need to re check though as i didnt blow through the jets
any help would be greatly apreciated
thanks in advance
You changed the back pressure in the exhaust and that is what causing your problem either put the washer back in or have the carb properly jetted

Always check your rpm and C0 settings.when you remove a part.
