I got the Vance & Hines Straightshots on today. They were listed for a C50 but fit perfect. It was the first set I put on a cruiser and it took less than 2 hours. It's raining here today so I was only able to go about 5 km but the fuel injection seems to work fine without the power commander, I have one on order but don't think I'll need it. Should know better after a couple good rides.
