2001 cr125 problems

[Cr125rider17]

I just recently bought a 2001 cr125, the owner said the bike needed thoughing and that he had just replaced top end. The bike has a aftermarket pipe(FMF gold series power core 2). I rode it once at Slades Park in Surry Va. After awhile of riding it took more and more kicks to start. Finally it did not start and the kick start had very low compression. I replaced the spark plug and it started but still had very low compression. Once I changed the plug it started, but Idled very high. I fiddeled with the idle screw on the carb but it didnt seem to have much affect for when I gave it gas it started Idling high once more. The bike now does not start. :bang: Any help would be great

Your engine is dead. That loose carb helped it breathe in dust, sand or whatever you were riding in. More than likely you need a top and bottom end. Also, the cylinder bore will be ruined. Probably around 500 dollars in parts. Motosports has smoking deals on complete engine kits. Get a hold of Eric at forward motion to fix your cylinder. http://www.motosport.com/offroad/pr...Engine+Parts+and+Accessories^subCategoryID~75, http://www.forwardmotion.com.mx/

yea, you need a manual and take it apart look at the top end and see what it did on top.take the carb off and the the reeds and see if theres sand and dirt in there.

Also, I would check your seal with the air box and rear carb boot, and cracks in any rubber boots.

If you need a rear carb boot I have a brand new one that I don't need anymore. I thought it would fit my bike, but got the wrong one and the dealer wouldn't take it back. Its for an 01 cr125.
