There's heaps of knowledge here. Search for it. Sometimes clearancing is needed. I'd go with stiffer springs either way.

Better upgrade 2nd gear if it's still the original 01 tranny for sure.cams are a preference on what riding you do most of and what your looking to get out of it I out a stage 2 in mine cause I do alot of trail riding and I went ahead and had the middle intake guide and seal ground 1mm just for insurance some say you need to some say don't I didn't take a chance and went ahead and did it stage 3 I think you do all 3 intakes but don't quote me on that one I read it on here somewhere ahwile back do some research on what you think your looking for

You need to decide if spending hundreds is ok or buying a 700. If your looking for power gear it did now ya ride, open the air box up and put an exhaust on it, then ride it, if not happy then do a stage two cam, if not happy from there you will spend thousands getting more power. I spend money in suspension and handling before I go in a motor now days.

Stage 3. At least with 700's, you don't fee a significant different between stage one and 2. And even with stage 3, you won't feel any real low end torque.

Stage 2 is the common cam for a 660 and may need springs. Stage 3 is normally for built motors like more compression, big bore, bigger carbs, intake and exhaust mods. As said though, start with the "Big 3" first. Intake, exhaust, and jetting. You should notice at least a 5HP increase. Next would be a cam, and they like more compression.
