Title: CR250 Crank Rebuild?
Post by: Xracer on March 12, 2012, 04:14:06 AM

I bought a nice, low-time 95' CR250 a couple years ago from the original owner that I've been slowly restoring into a McGrath tribute bike. The bottom end was tight and I had no intention of rebuilding it, but I had it apart for a new top end.  I started re-assembly last night and found that even though the engine had been shrink-wrapped with clean rags in the cases for the past 2 years, the big-end bearing had rusted and is now binding.  A couple questions;

1) Does anyone know where I can have the OE crank rebuilt with CARE?  I don't want an aftermarket crank, and Honda wants a small fortune for a new one.  I'm in Michigan, if that helps.

2) Since I'll have the cases apart, I'd like to have them cleaned up to look "factory" fresh...what's the process to restore cases to have that new, jeweled look to them?

Thanks.

Your local bike shop or engine builder should be able to handle that no worries.

Check with Andrew Cooksey. If a rod kit is still available he should be able to handle it for you. You'll not find one negative thing about him on KTMTalk or Thumpertalk, he is highly regarded by lots of folks.

http://crankworks.com/ provides crank rebuilding, truing, and balancing for current makes and models. I'm not too sure if they can balance a Honda crank, due to the stamped shields on the crank, but should provide the services your need. Are you dead set on rebuilding your original crank? If not, shop around you may be able to find a Wiseco or Hot Rod crank for less than the cost to rebuild your original. I bought my last crank from http://www.eric-gorr.com/ for a very reasonable price. I've heard some folks have had issues with Wiseco and Hot Rod cranks but I've been running a Hot Rod crank for some time without any issues...knock on wood.

cooksey would want to sharpen his pencil, $165 is a complete rip off. It's a $50 job even with the Honda tin can cranks.

Try Falicon in Florida.

That $165 includes the rod kit, the labor to install and true, and the return shipping.
