Hey guys I know I'm a little out of place being a flat track racer but, Anyone want to tell me why a 78 RM400C that was running a little rich would blow the top off the piston when it's wound up tight. I've done that to two of my motors so far. The only thing I can think of is that I used my 79 400N ignition because the 78 ignition went bad. Do you think it might just be spark knock ( as Suzuki is so clear on how to set/check ignition, just line up the marks, RIGHT ). I'm tired of putting $600 in this motor every other half-mile race. If anyone could lend any info. you'd make this riders day. Thanks Pete
