Plug reading 101
Ok , I have run into a problem with jetting my CR 144. I just installed a 1368 needle( Mr.Gorr's reccommendation) and reset my V-Force reed tension to the low setting .My problem is that I do not have a main jet large enough to get a good plug reading.I currently have a 180 main installed and the bike runs excellent through the whole range. I can ride aggressively for like 20 minutes and pull the plug it looks perfectly tan but not when doing a WOT plug chop(plug will be white ) I plan on going to a local race in the morning and am wondering if I can get away with running a richer ratio like 40:1 (currently 36:1). Would I risk engine damage ? Or will that even be enough to make a differance??If I recall Eric Gorr had suggested going to a 162-165 main so why Am I needing to go so large on the main Thanks again for ANY help on such a short notice.....
