I've got a 2001 Dr 650. I've started to notice a miss in the engine up to around 50km. I've taken out the carb given it a clean changed filter's. Is the a problem with most of these bikes. If so. Some advice would be great

I have an 06 DR 650. Make sure the small carb filter is clean, i use a small K&N that fits the about 1/2" tube, also try a new set of plugs.
