Technical / CR 125 compression test

« on: March 13, 2011, 06:44:10 PM »

Does anyone know how much compression a  2002 CR 125 should hold ?  I just did a top end job  and would like to check compression  just to make sure everything is good.

Technical / fouled plug

« on: March 13, 2011, 03:46:27 PM »

Well my first ride of the season didnt go quite as planned.  I fouled a plug right off the bat.  Luckily they had an accessories shop at the track office, where I bought another plug. The bike fired right up and ran great for an hour or so, an then after a little water break, I fired it up and I rode about 100 feet and that new plug fouled. So I tried to clean it  but no go. So I gave up for the day.    Does anyone know why the plug would foul like that ?  I never had a problem B4.   Last fall the bike ran great.  I think Im gonna do a little jettingchanges to see wat happens. Any help would be appreciated.

Technical / 2002 CR125 carb

« on: March 11, 2011, 07:58:41 PM »

Im having trouble with my mikuni carburetor on my 2002 cr125.  It leaks gas out the overflow tube continuously while idleing, but not while riding, as soon as I crack the throttle it stops for awhile, but starts again when it idles back down. Could the float level be off? I didnt have this problem last fall. I cleaned the crap out of that carb, so I know theres no dirt in there. And I just rebuilt topend over the winter, greased the linkage and steering stem  etc.  and did all the regular maintenance stuff.  Any help would be appreciated.       Thanks Dan
