VIN's / Unstamped sand cast replacement cases?
« on: February 17, 2010, 07:46:55 pm »
About a year ago a fellow called me up and said he was an old Honda dealer from way back, but sold the dealership a while ago. He had some CB92 stuff I was interested in, but he made mention that he had a set of unstamped sand cast replacement cases. Has anyone seen or heard of this? It seems possible that Honda may have sent some to the parts department if ordered, but I personally have not seen any.

I just got the exhaust off and inspected it. #2 and #3 pipes are unstamped and in decent shape. #1 and #4 are HM300, with #1 pretty bad around the joint between the exhaust pipe and muffler and #4 is pretty good. The #4 pipe must be a very early HM300 because there is no indent for the brake pedal like on all the other HM300 and HM341 pipes I've seen.

Steve- Thanks for the reply. I've got Andy marked down on my swapmeet map at space S-10. I'll definitely be stopping there. The part of the frame that is damaged is in the front down tubes in font of the motor, where they slide into the wishbone piece that the horn bracket is mounted to.

I figured out what the cracks are- bondo. Where the bottom downtubes slide into the slotted female end of the wishbone there is some type of repair damage. I won't know the extent until I get the bike disassembled and the frame stripped.
I'm going to Mid-Ohio and will see if I can find some of the parts the bike is missing. I probably should wait until I find out if the frame is salvageable before I buy more parts, but I only paid $250 for the titled bike and can always sell off what I purchase if the frame is trash.
The original sand cast cases are long gone- what happened to them is anyone's guess, probably chain damage.

I just picked up the bike. The engine has restamped smooth replacement cases with the 10 hole clutch cover. Frame has the horn bracket on the left side. Unfortunately, the frame is cracked on both legs of the wishbone down tube,- maybe from stress or a frontend hit? Was this a weak area of the frame prone to damage? I looked at my K1 frame and it has spot welded strengthening brackets on it, so my guess is a weakness in the frame design. Who is a master repairer of the 750 frames, especially with knowledge of the early frames? I will need to send it off for inspection and repair.
As far as correct original goodies it has the original ignition switch with matching fork lock, carb set, front wheel and brake assembly, handlebars and switches, rear fender and tail light.
The seat had been recovered, wrong bodywork, broken top triple tree clamp, plastic lenses broken on the guages, broken side stand frame bracket, boogered up single cut front fender, rear 16" drop center rim. It has decent HM300 stamped exhaust on it now.
I'll have to start stripping it down soon.
