Has anyone experienced/heard of the new CR125`s having problems with detonation? A few guys are saying it over here in the club that I race in and having just bought one I am a little concerned! If this is in fact true is there any easy cure?? :bang:
Slighty richer jetting (and even slightly retarding the ignition timing) can often cure pinging trouble as well, though I dont have any first hand experence with the 05 cr's its probably worth a try.
If you use straight leaded fuel like C-12 your bike will be VERY rich. Dont be suprized if you have to drop 3 jet sizes. If you make the commitment to run leaded race fuel have the head volume decreased to match.. You cannot EVER put unleaded in it again.
