Thanks again for the kind words everyone.
There could be a real market for parted out 250f's
I paid $500 for a brand new frame, subframe and swingarm from a
large volume Honda dealer. Those same parts would have cost
three times that under normal circumstances. In all, I probably
saved two or three thousand dollars on new components.
This conversion, combining a CR500 engine with a CRF250 frame is
one of the harder ones to pull off. Using a CRF250 frame and a 250
engine, or any other brand, should be much easier and also appeal
to more people as the four stroke frustration grows.
Is it for you or someone else? Are you racing it?
This one is for me and I can't wait to race it.
What did you do to the motor
I went all out on the motor. I scored an HGA lightweight, close ratio
transmission from an old friend, the crankshaft was balanced by Crank
works, all the rotating internal were Cryo-REM treated, Hinson clutch,
Cylinder and head work by Eric Gorr, VForce 3, Keihin 39.5mm PWK
and a 2001 CR250 ignition with a vortex programmable, switchable
ignition. Below are some pictures of the internals.
212 lbs is VERY impressive for the weight!
Remember that a CRF250R has a dry weight of 204 lbs. and a CRF250
engine is not that much lighter than the CR500 engine due to all the
extra parts. This bike was put on a comprehensive titanium diet: Fork
and shock springs, all engine bolts, linkage bolts, all fasteners, footpegs,
axles and even the brake caliper pistons. The light weight transmission
and CR250 rotor saves even more and lessens the "flywheel" effect
which helps the bike change direction easier.
