I talked to shearer a while back, he recommended the msd for the saber. said for drag racing the msd is the only way to go.So future plans call for sending my bike to Ryan Hormell at Hormells Extreme Atv in Lafayette. Ill let him order the programmable msd, install it, then dyno tune it to get the max hp and best timing curve out of it..he said its a little trickey to set up initially but once its setup its good to go... guess time will tell..
