Jim_M 178 #2 Posted September 24, 2011 Do yourself a favor and forget the 4 speed, it won't last. Get an 8 speed, 8 pinion transaxle. Share this post Link to post Share on other sites
jonsteffen 6 #3 Posted September 26, 2011 the four speed has the 1 1/8 axles and the 8 pinion i bored everything out to run the 1 1/8 axles :thumbs2: Share this post Link to post Share on other sites
Jim_M 178 #4 Posted September 26, 2011 Get an adjustable pulley for the crankshaft and a couple of different size belts. You can change your gear ratio by opening and closing the pulley. Share this post Link to post Share on other sites
