So i've got my alukit installed running a uni, estoril, sha 1412 with a 66 jet and it's spitting fuel from the exhaust. The plug looks a little rich but it seems to me after looking at the spreadsheet that a 66 jet on a kit should be on the lean side and i'm worried if i go any lower it's just going to be trouble. Before i installed the kit i was running a 61 and the plug chop was right on the money.

On other question while i'm at it. I'm waiting on a hi comp 70cc head and read the other day that you should down jet again with a hi comp head, is that right or should i leave it, run the head and hope it evens out?
