Stay away from the map for the HMF full system, and small airbox mod. Makes the bike run WAY rich. I use the map for just the yosh slip ons, and it could be a bit leaner in the higher rpm's but for the most part its spot on. I would see if they have a map for just the hmf slip ons and try that one out. I have yosh slip ons, drop in cams, stock filter, small airbox mod, 44lb fuel injectors. Hopefully it works out.
