I got a used MC21 recently, an oil pump was changed as it was leaking, now ONLY the plug in the bottom cylinder gets fouled after each test run, is this a problem of an oil pump adjustment or is something sticking in the carb? Any ideas or solutions? I appreciate any information. Thank You.
Thanks Andy. My bike is stock and ran very well with a new plug, then the next morning it would not start and the plug appears to be wet. Could it be a sticky float in the carb?
The KISS delimiter is by far the simplest solution for an MC21 wire-splice, and definitely worth fitting if you don't want to cut and splice your standard harness.
Any modification requires checking the jetting, and this is no different. Put it this way, you're releasing approximately 15hp (around a 35% increase over stock) from the motor. You'd be mad not to check the jetting! _________________ Andy.

It can be your float height so check that. Do you turn your fuel tap off after every ride?
Sounds like a float valve problem
Float valves are fairly cheap to replace. I don't think the seats that the values seal against can be replaced though. I found it best to replace the fuel tap and turn the tap off when not running the bike. Also keeping the bike upright on a paddock stand helps alot _________________ Why do things simply when you can complicate them
