Hey Greg,
Yes I look and read more than I post, this is a great site and the only chance I get to keep in touch with these classic Honda's, mostly superbike riders here in sunny South Africa.
I gather the CB750 tappet covers will also fit the 350 twin? I could also manufacture a batch of those finned tappet covers if there was a call for them, would not be as cheap as the cast covers that are on Ebay though!
If you speak to Terry let him know I have been trying to get hold of him. Thanks.
Kevin.
