Laugh all you want, but if my only goal was to just beat you I would just slap my YS 110 or tuned 91 fx in there and hang on To get absolute maximum power out of this particular engine is what I`m after (without using a long pipe)[X(] I have flow ported the sleeve and now I need to test different plugs, fuels and possibly tach it with one or two less headshims, drill the stinger of the muffler. I find this very interesting and fun and can`t wait to get a chance to experiment more with this rather pretty engine, damn weather[:@]
