How to know if the bike is running lean?
Hello GG riders!
I purchased a gas gas ec 250 2006 a few days ago from a family member with a spluttering problem.
Basically it would start first kick every time but the bike would splutter very bad at anything more than 10-20% throttle, I solved this by running a hotter plug (br9) and changing the mixture from 40:1 to 50:1.
Now I am afraid the bike is running lean, I put a fresh plug in and took it for a test ride for approx 5 minutes and the plug was a very light colour, yellow/white colour which I believe means it is lean?
Is there some sort of trick to finding if it is lean? If it is lean how do I go about making it richer?
My settings:
Pilot: 42
Main: 172
Needle: #3
Needle type is "N1EF"
