MikeRC, I try not to criticise but I'll have to agree. If you go thru all that trouble why not go ahead an invert your engine??? Or spend the $$$ if you can and buy one of RCV's 4 strokers. Bignasdy, IMHO amigo you might as well stayed with the origional cowl. A big ole' cylinder head stickin out of the side just doesn't do it justice with all that extra work. If it were me, I would put a four stoke inverted on it with a "flex exhaust" and try my best not too muck up the lines of that pretty bird. These opions are mine and not those of RCU..... [8D]
