I have done this before on other vehicles of mine, i saw a post here somewhere about it also. In that post/link it said when doing it to reduce the gap by .010. So I tried it on my bike, but started with just over .030(my gauge doesn't have .032 on it). No noticeable difference, so I dropped to .020 like suggested, it seems to have made starting rpms slightly lower, like I almost need to rev it slightly for warmup. After its warmer it seems to idle slightly higher though. Anyone else do the side gapping, what gap did you end up with?
