crf450 187 cam carbon pro

Recommended Posts

I was running stock needle 3rd clip 45 pilot and a 170 main. The temp was 50-50. Now it is 90-95 and I cant get it to idle. The fuel screw doent do anythig.It is realy rough and stalls out quick. It is also hard to start hot. I lowerd the pilot one and no help. So I moved the needle to clip 2 and a 168 main. I seems to idle now. :thumbsup: But doesnt that seem to lean? Any help please.

At those temps I bet its way rich. Drop the pilot to a 40-42. If the thing idles with the screw in all the way its too rich on the pilot. That cam doesnt require a lot of jet.
