Claudes cylinders are as cast in duration like he said 189/122. I ported the intake, transfer tunnels, matched the transfers to our gasket that fits the cub cylinder and cleaned up and polished the triple and main exhaust ports with out changing heights.
With the lower port timing and sniper pipes the peak rpm is going to be lower than the high porting timing bike we tuned recently that was at like 10,500rpm peak with shearer small bore pipes. Without any dyno time with snipers I cant predict what they'll do but Id think both differences should pull the peak rpm 1k or so giving the front side of the curve a little better pull and tq come up a earlier with a long and linear graph.
