I got my mte all broke in and race tuned, still a bit rich, but tons of power. Not really thrilled with the 2013 pipe, but I am running oval, and need a high speed pipe. I was averaging about 4- 5 minutes on a tank. We run full out all the time though. I have a 7.5 restrictor in it and a works medium pro clutch. I use byrons 30%. I think I am going to drop to a 6.5 restricter to increase fuel mileage and decrease the power a bit. I love the motor easy to tune, has way to much power, and a lot of bottom end. I like the fact that it has a lot of bottom for coming out off the corner, but in a way there is to much bottom. Hopefully a different pipe and softer clutch will help. All in all its a great motor and I am very happy I bought it. Thanks for all your help! You guys are great!
