gowen:
Hughes, a few people have had good experiences with Eric Gorr and his replating (he uses US Chrome), you could have him to some porting while it is in his hands too. Who knows, maybe even a big bore. :-D

hughes:
Thanks I was am going to send him an e-mail right now. What will a port job do for engine if I keep the standard bore size :?:

gowen:
Well, you can choose where you like the power, low-mid range hit, or a mid-topend hit, or what you call Mo-Better which he just works the ports to give power everywhere, like a spread out type deal. I had mine ported for mid-top hit, but that was cause he was doing a big-bore which usally tends to rob the top-end power. It is better to call him than to e-mail, he has never returned an e-mail from me. You could also post on dirtrider.net under the Eric-Gorr forum.

hughes:
Thanks, I was just on his site and looked up the porting for diff. powerbands. Looks like I will call him. Porting looks to be $200.00. It would be nice to have some port work done to smooth my power. This 87 500 has a tubo powerband. I think I will need to just get re-plated bore.

hughes:
My honing turned out good. The plating did not flake at any of the port openings. I'm going to install the new top end and replate later.
