RAD Flywheel Drag?
Anybody running a RAD charging flywheel on their ski? Just put mine on (ran a stocker before) and feel an increased drag when I turn the engine over by hand (i.e. the engine is slightly harder to turn over with the RAD flywheel than the stock one). Just put this engine together and have not tried to put the stock flywheel on, but don't see how I could have mis-aligned the RAD one (if that is what I am feeling).
I'll probably swap flywheels tonite to see what happens just for peace of mind, but wondered if anybody else has noticed this. Was thinking that maybe the RAD has stronger magnets and that's what I'm feeling?

Flywheel should not stop motor from turning over easy.
If its on a GP1200 I would take it off and put the stock one back on.
Have heard of lots of cracked flywheels.............

if you'r last motor was low on comp the new one would be harder to turn over.

I'm turning it over without the spark plugs in, no comp. It turned pretty easy with just the cases and crank. Then I put on the flywheel and its cover and noticed the drag. Put the pistons and cylinders on next thinking that it would be easier to turn over (without the rods going every which way), but the drag was still noticable.
When I put the RAD on, I tightened it down by hand as tight as I could get it, then wedged a small piece of wood between the flywheel and the case to hold it while I torqued it down. I was wondering if that had somehow mis-aligned the wheel slightly, but I don't see how it could once everythign was torqued down to the proper spec.
I'll stick the stocker back on tonite and let you guys know what I find.

To remove the coupler or flywheel take some old jeans and roll up a section then place into the exhaust port and wedge it between the piston and the cylinders.
Flywheel and coupler have different torque specs.
New motor should have more comp than old motor.
I would ditch the rad flywheel I have only heard bad things about them.

Have Crankworks lighten your stocker. My RAD flywheel drove me crazy for 2 years, then it blew up.
