I have a new CRF250X that smokes a lot. At idle, just a wisp of smoke is there. When it warms up, it gets worse. At fast idle, smoke boils out the exhaust, like a cold 2-stroke. Blipping the throttle makes it even worse.
Anyone else have this problem? Owners manual doesn't give any break-in procedure. Will the problem get better? Anyone have any ideas? Very disturbing! pando @ verizon.net
