Well I have a long history or racing atv, motocross and sxs and now getting into mowers. Up here in Canada our local event have an open class so can do pretty much anything as long as it's got a hood. I was thinking of running a 1 1/4 axle with either a RAGB or LAGB. Do I need to run a cvt system with that off of the motor? Could anyone point me to right direction or forums I've been reading these this forum for a few days and haven't found the right awnser dummy version lol. and my mower has a 16hp twin
