Well after my wreck i started piecing together the m2. Well either i broke the flywheels on impact or i bought them broke. Since the motor is going to be broke down so far why not make it faster right. Obviously i need new Lightened flywheels but any other suggestions?

Well, if your going to split the cases and all that, put a stroker crank in it and stick in the biggest big bore that they make. Since you have to break it down anyway. Shoot, I'd love to have an excuse like a broken crank to peel my bike open. I'd do it just like that.

A stroker crank can severely limit your rev limit and reliability. Go big bore if you must. Leave stroker cranks to dragracers and Harleys.

The 2000 up crank is fairly easy to install with a little machine work...or there's a couple sponsors here that could lighten/rebuild the stock crank if it's serviceable.

Get a darkhorse crank job. (crank job... heh heh heh)

Rev performance used to offer it but it originated with the Hoban brothers. http://www.darkhorsecrankworks.com/

Look at zippers or NRHS thier 88" and 90" kits. With cams and Head work you will be satisfied. The 1250, cams and head work isn't that much of an improvement.

Well ive been drooling over my computer looking at the NRHS website for months now. SoOo we'll see. I saw a 90" and an 88" kit at Revolution Performance but they look like milineum cylinders. I read about problems with the cooling fins touching and causing cracks. It was an old post though and i was wondering if they still have this problem??

That was rectified some time ago. I believe the only clearance issues now are with Mikuni carbs and XB pushrod tubes...they need a little grinding.

Here is a step-by step photoblog thing of a guy turning a new 883 into a 88" hell beast:

I love that he didn't even bother to ride it home!
Just tore it apart with ONE mile on it.
