In 2003 I put a 540cc kit on the bike which included mild porting, shaved head and a new intake set-up. I used a rad valve, lectron, and K&N. I later added a intake spacer. I ran a Pro-Circuit Plat. I also cut 6'' off the Pro-Circuit silencer to cut down on restriction. That worked get! I started with a 5-1 needle. I blew the top end in an hour, I was in a hurry and didn't have time to tune before my first hillclimb. Then I rebuilt the top and switched to a 6-1 needle. With a few days to tune I got it right. Then I was able to race 10 more races problem free. The carb was expensive, but way worth it. At the end of that season I did end up running it out of gas. That wasn't pretty. I came across a crank shop ad in a mag. that claimed to beable to stroke cranks. I hadn't ever heard of stroked 2's. I called and the guy said he could balance and stroke mine. That was the beginning of a huge equation to figure out how to finish the motor once we had it done. My builder accepted the project under one circumstance. I buy a Digritron E.G.T., so we tune this monster one built. The motor is done, but hasn't been fired yet do to exhaust. I've talked to three pipe builders and they all want the bike to build it. They'll all in California, a couple thousand miles away. We're going to run oxygenated fuel. We're hoping for 100h.p. If your considering a Lectron for your sled, you may consider a Digritron if your going to be in different climates and temps. That's where the Lectron pays off. Being able to turn that wonder top screw to change fuel rate instead of changing those d**n jets. I'll never change another jet again..
