I bought a replacement lever and put the plate in (there was currently no choke plate in it) and noticed that the jets were currently #62 and #165. This seems really rich compared to stock yeah? Especially as it doesn't have an aftermarket pipe.
So my question is: would there be any point using the new choke, since it might just run way too rich and flood the motor?
Also should I decrease the jets so it's not running so rich? The plug was completely coated in carbon and looking at the piston through the sparkplug hole it seemed to be black too.
Extra info: has a 630cc kit but not sure how that would affect jetting that much surely?
Thatīs the stock jetting used in Europe, here in Portugal they came 62/165 from 91 up
