Hi Everyone,
I have a 1990 Banshee with Stock engine FMF pipe, K&N filter and FMF reed valve. Everytime I come back from riding for few hours, the new spark plug becomes black and little bit wet. I had to change spark plug every few hours so I don't have problem getting it to kick start.
I use NGK B8ES and 26mm carbs with 300 main jet, 30 pilot jet, 2 turn out air jet. I use Motul 800 systhtic oil mixed 40:1. I run my banshee 1000-2000 above sea level.
Any suggestions? Thank you for your help and Happy Thanksgiving.
