Last fall my 400 Foreman quit so I let it set till now. Yesterday I was looking it over and found that it has intermitant spark. When I push the start button there is little to no spark at all. When I let off the start button it fires once or twice then stops. If I keep pushing the start button over and over and over again it tries to run but will not. It fires every time I let off the start button but no start. The battery is new and at full charge so I know thats not it because it works fine in my 3 wheeler. The air cleaner is clean and its getting gas so I have to beleive that its electircal. The coil test good so that leaves the CDI box, regulator or the stator. Who can tell me what ohm readings I need to check the stator and the regulator? Also is there any way to check the CDI box?

TIA Fuzzy

Well this just sucks

I was sure someone would help a guy out here. I guess not as there have been 66 views and no replys. Looks like I'll have to break down and buy a manual.

I had to re-send the shop manual sections ... The first email with all 3 sections came back because your ISP or mailbox wouldn't accept the file because of size .. I re-sent the sections 1 at a time and I think you got them this time ..

I have never had that problem with my bike, but my sled was doing the same thing. It was the stator.
