Ported Cylinder

[cmotodad]

Through a good friend, I was able to have Cliff White port a 500 cylinder for me. For those that do not know of him, he was with factory Honda during the Bayle, Stanton era. All I can say it what an incredible difference. There were parts of the powerband that I had a hard time coming to grips with. The motor now has the tractorlike pull that has a few more revs but is so much better to ride. I think the motor feels like it is so much smoother both in power and vibrations. He still does amazing work with the porting tool. I am doing an 01 250 and he will doing his magic on that cylinder too.

How can we get in touch with him??

Next time you have the jug off, map it for us.

If anyone is interested, I can reach him and make connections. He is a very private guy who wants to take on a small amount of work. You can PM me for further details. As far as mapping the port timing, it took many years at Honda to develop.

May I have an idea what it would cost a guy like myself? I'm trying to budget my bike overhaul right now.

Both Tom Morgan and Eric Gorr claim the 2000 CR250 jug has more potential with a port job than an 01.

2000's had a T on the Jug, 01's have a V next to the reed cage.

Thanks Sean. I am looking for a cylinder for that 250 project. I will keep that in mind. If you know of one, let me know. Bob

I assume you want a virgin jug not a ported one?

I've got a 01 with fresh plating, hasn't been installed or run. Matching wiseco single ring new piston.

Also have a TMR 00 jug with full tilt outdoor MX port job that was done for the blackfoot team. With the correct ignition/pipe/carb it's in the 57 HP range I'm told. Very close to the HRC stuff of that era. That jug needs plating.
