Have read all the posts/stickies on here and there, just want to clarify: CR 250 CDIs went digital in '00 and while '00 and '01 have ideal maps, post '01 CDIs also work fine, right? One can just silicon the unused electronic power valve control servo plug? And the ignition coil can be original CR5 o...

Happy New Year all and thanks in advance for any insights. I've installed a '01 CR250 digital ignition in an '86 motor. Bike ran OK though spark was weak, ie yellowish; now it's non existent so bike won't start. With an ohm meter I have discovered: 1) Stator plate is short circuiting to ground 2) Pu...

Eagle eye indeed and well, that'd explain why the '05 CRF plastics fit. duh!

was told suspension was out of an '07 CRF250, can you tell if that's the case!?

Norcal, Pleasant surprise indeed. Am guessing I have an '04, and hence Gen 3?

thanks for the prompt reply. will get a measure on that and revert. here's a piston shot. a few slight vertical scratches and just below the second ring you see where the grey is worn off which matches with some glazing in the cylinder wall just above the exhaust bridge (other pic). otherwise the in...

Here's my story: '86 engine just rebuilt the motor from the crank up and compression is only 125 psi (know protocol and used two different testers). Also passes all leak tests, new top (and bottom) and bore (1.5 over). Pulled cylinder after only 1.5hrs of ride time and cylinder wall/piston all look ...

After a year lurking, about equivalent hours to earn a law degree I reckon (not that I'm a lawyer!) I'm finally introducing myself. Long time rider, street and dirt, an American expat in his youth of old age living in Hong Kong. Got China's first CR5! rebuilt from crank up '86 motor in a '97 CR250 f...
