I have a WC223 with stage 1. With a TAV and 60T it was great on my CT200U-EX. I'm now planning on building it up some for my new full suspension MB200S. I don't really want a high revving engine. I want low end torque. I spoke with tech at EC (they're great) he suggested. A pinnacle rod, this creates more lift and so the compression ratio goes up too 10.5-1, 1.2 ratio roller rockers made by NR Racing, 26lb valve springs, 6 degree key that will put timing at around 32 degrees, set valve lash for intake at 0 and intake at .001, 6000rpm limiting coil, with stock carb use a .36 jet if running a header with muffler .38 open header. I might even go with a WC22 blueprinted slide style carb. I've already done some port matching and porting/polishing. He said I should see a significant HP and Torque increase. How does this sound too y'all ?
