I've been trying for 6 months to figure out whats wrong with my 01' RM 250, and finally got the jetting almost right...
The past few rides however at about 1/4 tank fuel the spark plugs just completely die! I've tried both b8es and br8es plugs and they don't even really looked fouled, just seems like alot of carbon type buildup. I put a new plug in and it fires up and runs great until it kills the plug! Removed the magneto cover and it was pretty dirty inside, so I cleaned it out with non chlorinated brake cleaner the best i could. Rode it with a fresh plug and same thing, it died around 1/4 tank fuel. Do magneto's go bad like that, or do they just stop working all togather? I don't really understand where to look next, any better way to clean the magneto? Those suckers are expensive, like $300 i seen!
