I originally ordered the andrews H48 but while waiting for my thundermax tuner to arrive, I decided I wanted a big bore kit as well my bike has always been hard to start hot and I don’t have compression release heads so I got s&s mr 103 easy start cams and an S&s 107 big bore kit. I have not had a chance to ride it yet because after 4 weeks of waiting jp informed me it was gonna be 2 more weeks before the tuner would arrive so I had to cancel my order and ordered one from Fuel Moto yesterday, I have started the bike but have not rode it yet but it starts and restarts easy the cams work great!
