Okay, I appreciate both of you sharing your knowledge! It sounds like you both believe that this 2 peddle one wouldn't give me much more throttle response and torque, and just so I understand, it also wouldn't require much of any porting except getting the piston? Would you guys say that's pretty accurate with regards to this 2 peddal one? It's too bad really, I liked that it had no offset and works with my current carb, but if it sucks, it sucks, haha. My PK80 has 47mm cylinder with 8mm studs and came with a 32mm intake that has been ported. I'm currently using a 15mm billet intake. The bottom end is a 40mm stroke.
It sounds like the 4 peddle OZ one sounds like the one to get. How difficult is it to port for someone who is still kind of a beginner? It's possible I can ask my friend with the mill to do it, but he's a busy man and I should really learn it. I have a flexible multi speed dremel. It would be okay if I have to get another cylinder. I will do some more reading up on these things and I will shop around for the 4 peddle ones and see what I can find.
Thank you
