If you recall in Vol. 41 No.10 we freshened up the motor with Screamin' Eagle parts which included a new cam, a set of tappets, pushrods, .010 over pistons, and head and cylinder work. Going into this build we knew that a stock 80ci Evo would only have around 50-60 hp so any gains would be good. But we were excited to see what the new parts along with the air intake and pipes would pull out. Dave placed the bike on the dyno and logged in all the bike's info.

17. Once the bike was brought up to operating temperature, Dave twisted the throttle and on the first run the bike pushed out 70.1hp and 66.7 lb-ft torque but was running way too rich at the top end. So after a quick main jet swap from a 76 to a 72 and one more run, the bike topped out at 77.1hp and 73.4 lb-ft of torque. The first thing Dave said was that if the pipes had baffles (backpressure) we could do better. Something for us to think about in the future, but as for now, Chris just wanted to ride the bike and enjoy the investment. Enjoy Chris!
