Your gonna need head work springs and cleared rockers for the 5050. It's leaps and bounds over the hc2. It's great for me but maybe not for you. How do you ride. Oh if you don't go 11:1 piston you'll lose a lot of bottom end. It's not a drop in cam like a HC it's a big boy cam. Some say the best some say it's garbage but there's ton of custom grind out. It's according to what you want. But for the 50/50 contact DL700 he's the owner of the pattend he sells whatever aftermarket parts there is and some custom ones.Where can I find one of these cams? I have a stage 2 Hot cam sitting on the bench that I took out of another Rappy and was going to put that in for now. How does it compare to the 50/50 cam?
Now I gotta pop my head off. Check piston and head out. From where a throttle plate screw got sucked into engine. I may change from 50/50 to the 51/50 and 14:1 with inframe drag pipes. Trying to build a 90hp n/a bike.WOW!!! 70HP is huge.....must be a damn good cam. Did you have any head work done? What is the +3 TB?
