Dyno Testing 1985 RZ350 Yamaha

Once I had the engine back together and some break in time on my 1985 RZ350 Yamaha, I needed to throw it on the dyno and do some testing. I wanted to find out if changing the ignition curve helped or hurt power. I also wanted to confirm my jetting here in Colorado Springs at 6000' altitude was okay. The initial pulls resulted in quite a bit of smoke in the test cell area, due to the excess oil I had in crank area for assembly, and because I was running a small amount of oil in the gas (premix). I just wanted to be extra sure the crank and pistons were getting enough lubrication. Once that oil burned off, there was much less exhaust smoke. The engine made adequate power for only 350cc, a dyno sheet is shown at the end of the video.
