So, I'm hoping I have made good choices for parts. I know there are lots of mod threads, but they all seem a bit different or are looking for different results. I have ordered a PVL flywheel , standard length billet rod, 10.8 pound "improved" springs, and air filter and adapter.
I have removed the governor completely, but went with the lighter springs because I'll be happy with sub 6000 rpm. Went with new flywheel and rod for safety since my boys and I will use the bike...(my fat tire bobber in the project logs). And, who knows , maybe some day I'll use the parts for another project.
I've drilled the jet to .035 , for now, and ported the intake and exhaust slightly to remove the sharp edges and round the short side radius...once I figured out what the heck that was... :laugh: I left the intake with a rough finish. I'll also lap the valves.
That's all I plan to do for now, hopefully I haven't done anything that will hurt the low end..? Or having a decent low idle? I read that the lighter flywheel could affect that. How about the 28 degree timing on the flywheel, is that even a bit much?
The bike will have 22" wheels and the gearing I'm starting with is 12.96:1 (10-24-10-54), but that's easily changed. I wanted to start low because we have some hills and rooty trails where top speed won't be too important. :smile:
