    Probably overkill for me, but I'm interested. Don't know if I told you but I'm planning on a conversion to a higher cc, but not really wanting a true racer. just more fun(speed) i guess. I know you're trying to sell but, any honest thoughts? Don't wanna buy it someone wants it to really race. BTW, how's the new gig? Haven't seen you on in a while.

    It's good, been busy, doing both that job and still doing work for my old one.

    I just got back from a 5 day camping trip to the Hoh rain forest, we took out motorcycles. Was awesome.

    About the head: The head is fine for whatever size you want to go. It does have HD springs, so if I were going to use this on a street bike, I'd at least get the midrange cam.
    I figure stock-ish compression, hot 'street' cam and some 26mm mikunis with this head would make for an extremely quick street 350. You'd lose a bit of the top end compared to a full on race bike, but 0 to 100 would probably take a lot of people by surprise.

    How have you been?

    Things are good. New house stuff is mostly done, so I'm getting back in the shop to work on the 350. Also, a friend's brother just brought his '77 Triumph 750 up from Austin, TX. And decided to sell it. I'd say 90% of a restoration is complete. Been riding it around some. Fun bike. Lot's of looks for sure.

    I have bought (sorta, long story, maybe barter is a better term) Web-Cam camshaft. Lift is .333/.333, duration 270 and 248 at 0.05". Not real sure where I was gonna go with it, but next to free is a pretty good price. I'm really not worried about the top end for my use of the bike, and a quick 0-100 would be a lot fun. Also have gotten hagons for the rear bought, but still looking for good front end to buy and modify with (prob) progressive springs and such. Trying to find a junked CB550 around here (don't really trust buying that kind of used part without putting my hands on it), but no luck yet. Have found three old kaw's that I need to go measure and inspect. Might work.

    Anything will work if you knock out the neck dowel and weld on the honda one.

    That is my main concern on. Didn't know if that was possible. Not sure if I would trust myself on that kind of structural weld though.

    35mm is what I'm looking for...Really had come to the decision to keep the stock ones, until I took them apart. Not good. So I'm upgrading.

    Any cb500/550/750 is a direct bolt on. Stanchions from the 750 will be too long, but you can slide em up into the triple.
