Since im only so far going with the stock bore size high comp pistons there is a good chance i might actually have to go slightly leaner, maybe, seems the guys on the roadie forum when doing the same also went leaner, but going up to the 108 you will have to alter the mapping for sure.The roadie guys have been way aheah of the warrior on mods and even though they have carbs the fuel is still the same fuel.When mine is done ill post the numbers before and after on the dyno.I still wish power commander would come out with a PC3R for the warrior, S$%^ they have one for the fuel inj hardleys.
