I'm giving serious consideration to the Fuel Moto Big Bore 98" Kit even though it may be a bit over the top for my style but its a complete top end that (less heads) that sounds awesome.
My question; has anyone built their motor with this kit and what is your take?

 

I built my RK to 98". I didn't use FM, I sent out my cylinders and had them bored. I like the way it runs. I had the heads ported & polished and had the springs replaced so I could run a high lift cam.
I only did it because it needed a refresh up top due to high miles. So if you like the way it runs now don't bother.
