Jetting

I have a non standard exhaust my plug was white and I would bog at 45 i changed the 125 jet to a 135 now it bogs at 55 would a 145 or 150 jet be too high for a 125 or is it try and see?

I'd like to get it back to 65 as it did before.

 

What scooter and what carb? Or put the std exhaust back on!

 

just buy a 150 and try? no harm in going a little too rich. if the 150 helps you could try a size smaller and see if it helps or a size larger again. theirs no right or wrong answer, whatever your bike runs best on is whats best for your bike lol

 

Thanks i have ordered a 145.
