Carb problems

Recommended Posts

Okay right to the point my 2017 Suzuki dr650se has ran rough from the day i got it. It is not rough id say 1 to 3000 rpm but after that it vibrates bad, and if i rev it half throttle than hit it to full throttle it stutters and than hits. Only reason I think something is wrong is that my dad got a 2016 dr650se and its smooth as can be both bikes have dynojet. But my bike vibrated like this from the day I got it just never thought anything of it until i rode my dads bike now its bugging the crap out of me!!!!!!! Went through and cleaned entire carb twice the bikes are supposed to be the same so what gives any insight is much appreciated valves are in spec also it has fresh oil and filter

Have you adjusted the mix on the carb?

Yep 2.5 turns out, than tried farther in and farther out did not help so i put it back to 2.5 out from lightly seated

Above 3000rpm it will be to do with main jet and needle maybe to rich.

Also check that the spring inside the carby on the slide is in correct and also check that the plastic seat for the spring is on top of the needle clip to hold it down
