Cincy, you don't have to run one of those 836 Honda's, I've been running a Yamaha 600r, since 05, it now has over 60 nights if racing on it, and is very competitive, I built it as a dummy, out of parts from different engines off Ebay, really never intended to run it, all it's had is a new set of plugs in that time, so don't let the engine thing run you off, this season we have at least 1 Kaw, 600, a Suzuki 600, and my Yamaha 600r, not the R6, which is still in the car, from 05. It is new technology, at a fraction of the cost, you still have to cut and plate the engine to run the QC, but you don't need aftermarket anything, just bolt it in, and go. If you feel the need, you can go to 700cc, but with most of these engines, enough parts will interchange, you still don't have a bunch in them, and it's all stock parts. Rod bolts for mine are $2.50 ea, as compared to $300.00 a set for aftermarket pcs. Bob
