Whats up guys? Long time no see, it looks like I have not posted in about 4 years!
I am helping a buddy troubleshoot his 250R this week. He fouls plugs pretty often, usually one per ride. Here is what I know.
On the carb: The jetting seems to be close all the way across the throttle range, no surging, sputtering, bogging or anything. It has never missed a beat and runs like a raped ape.
Fresh piston, rings and bore: made no difference.
Electrical: I think the gremlin hides here. He reduced the gap on the plug and it seemed to help it not foul them, but then started again. Thats what makes us think it is here.We have been trouble shooting with the clymer manual and almost everything checks out but...
The secondary coil test, I think it should be 7.4k to 11k ohms, and it is 3k ohms.
The kick test, it seems to spark weak but it is blue. Not fat, just blue.
The stator, pulse generator and everything else is within specifications, but there is no real way to test the cdi box.
Do you all have any ideas?
