Reds,
You mention above that one of your mods was to move the postion of the stock cams to retard the timing 10 degrees. I believe this mod is the same position that the V Force cams come stock. That being the case, does this mod result in moving much of the power band from the low-end to mid-range? If not, what kind of improvement does this mod do for the P650?
Any comments would be appreciated!

mikey, retarding the cams dosen't really move the power band (because of the CVT) it just makes better power everywhere. The potential of that little engine is there. I built one this summer, same as Reds's but with ported heads and a little more compression, made 42rwhp and ran 5.9 secs in 300ft, just did another this week with 45.76rwhp.
