Thanks for the reply it runs perfect the tach didsweep when I first got it , also noticed it's hard to start most times , I haft to actually hold down the accelerator to get it to start about 80% of the time just wondered if it was a software issue. other that that it runs great there is a big difference in my old one verses the new one old one will go pretty close to 70mph the new one must have really low gears in 5th gear every 1000 rpms is 10mph at 50 mph in turning 5000 rpms so about 30mph is as fast as I go in it. Thanks Again for the reply. Matt
