It sound about right for the machine shop work, maybe. I had my heads done by Larry's Motorcycle & Machine Shop, in Oak Lawn, IL. (wfolarry@larrymotocyclemachine.com) for $679.00, this included shaving the heads .030, Porting the heads, Bigger intake and Exhaust valves (2.00 intake & 1.605) new valve guides, cutting squish groves on heads and installing the Woods W 188-1200 Springs which are the springs for the 650 Cam. The woods cam W-6 HF cost $350 and the springs $280. I did not cut the cylinders down because, for one could not find a place to do it and next was told by Larry that the squish groves on the heads would pretty much take care of any detonation. I instead opted to use thinner gaskets from comatic to reduce the deck hight by .023 by using Comatic 0.030 head gaskets and .010 base gasket. The stock head gaskets are 0.043 compressed and 0.020 base gasket. This gave me about 10.5 or so so compression which compliments the 650 cam very well. I can still use pump gas and not have detonation problems. The Comatic gaskets cost $66 (part # C9931 for the head gasket and C-9935 for the Base Gasket. You will need one each (sold in pairs) I also had the cylinders honed and new rings. I spent a total of about $1,500 and did all the work myself aside of the Machine work. Bike sound great, I also added a PSI Carb and Street Walkers 2-1 Rpgees. Loud you say, yes very loud and mean to. I only got to put a few miles on it before I parked it while my rear fender is being worked on, but sounds mean. I hope to be back on the road within a week or so.
