My buddies have all had banshees over the years, but none of them were modded. I just currently picked up a banshee with a very strait frame, but a blown motor. I thought I was just going to bore the motor and rehone it, but I found alot more problems. The previous owner threw a rod, cracked the crankcase, and destroyed the right cylinder.
So now I have got a new set of cases and I am thinking about getting a new cylinder kit for it. I mainly ride trails, and the trails that I ride have alot of open places like fields and long roads were you can really open it up. I also really want to be able to outrun all of my buddies.
So my question is what kit to get. What will be the pros and cons of a 392 versus a 421? What brand do I need?
