My '93 CR80 runs fine until I put it in gear and try moving around. I get about 20 yards before the spark plug stops working and the bike won't start again.
When I pull the spark plug out, tip/electrode is black and wet like it was dipped in dirty oil. If clean it, the bike will start and do the same thing... run until I put it in gear.
I installed a new plug and was able to ride around for about 2 minutes before I shut it off thinking I had solved my problem. Today I found out I was wrong :)
I just cleaned my carb so fuel flow is not a problem... if anything it seems like it's getting too much fuel, although the air screw seems to be functional and I can lean the mixture up as much as I want and the spark plug will still come out covered in black liquid.
Does anyone know what the problem could be? :bang:
