I test ran the engine this morning. It wasnt too bad for power. I was getting 7400-7500 on the 16-6 apc prop. Again, the only thing different from stock was the carb, muffler, no head gasket and no backplate gasket. It isnt a "bone stock" test, but its close enough. I am uploading the video to youtube as I type this. It takes a long time to upload, cause the video is in HD. I have torn the engine down, and am going to port it some more. I doubt that I will run it again today, but ya never know. The new ring hasnt came yet [&o] I really wish that it didnt take so damn long for stuff to cross the border. I expect it to be here next week. Frank said it usually takes about 10-14 days to get here. Another thing that would help the engine that I tested today, would likely be a new set of rings, but I want to try a few other things first. I also kinda want to get a header bent up for this thing, and try a canister. I would like it if the engine was a bit quieter at WOT.
Another mod I want to try is changing the timing of the transfer ports. In stock configuration, the tops of the transfer ports are level with the top of the exhaust port. When I increase the timing of the exhaust, I think it would further increase power if I also increased the timing of the transfer ports. It will be a b**** to work on them, but I am very interested in this mod.
