After speaking with Stuart at Krazyhorse, i was surprised when he said that the larger throttle bodies made no difference even on the Dyno.
They come in 52mm 58mm and 66mm.
All they do is reduce icing. So if your 3 wheeler suffers from this. It may help.
Cams i think from memory are 545 569 and 618. 618s are an interference fit. With the 618s you may need the 650 spring set because of the higher lift.
Roller rockers do not make a large difference on Stage 2 or 1 engines. Stage 3 and above get a boost from them.
Somewhere i have the S&S parts list. When i find it i`ll make it available.
