Interesting.  Most of us dream of building a "monster" motor and he wants to "unbuild" it.

He may have easily been able to swap his engine for a stock one also vs BUTCHERING the RC engine. Now, that was a shame.

We're still here if he needs us.

I'm sure there are some guys here that gladly will swap engines with him. A good complete stock engine for the RC engine with all parts as it was. I'm sure that the value of the engine is when complete with all RC stuff in it. Parting out cannot be an option, right? There are better alternatives available today.

I prefer a complete crank with rods from APE. New RC grinds from Dynoman or Megacycle grinds from MRieck.
72mm Pistons from already mentioned guys.
I'm sure that MRieck make better port job than RC did back in the days when the knowledge about porting has been further developed during the years.
5mm valve stem is newer stuff, right?

I know the camshaft and valve cover did sell on ebay, the rest never got a bid but he hasn't relisted the parts.  When I asked him questions about the parts on ebay he didn't seem to know much about the RC stuff.

interesting that he talks about having an early non f3 head on it?if he wrote the book he would know about oilways etc?bill also his description of how the early swinger would mount does not line up with what I have read?

For someone that writes with such authority he doesn't seem to actually know what he is looking at, have any historical information or a thirst to find out the real answers.
Shame.

This was the guy that bought the bike, then tried to flip it a week later and after that didnt get his money back took it apart?

Supposedly the crank and rods are also sold.  Just got an email back from him.  Also said he is considering using the big bore pistons with a stock crank and rod combo!  I offered to buy some of the misc parts but my price must have been too low as he is trying to sell the parts to someone else.  Oh well.

He is NOT known for 750's, just the little guys. We are known for 750's which is why we know more about these bikes. I do NOT not #$%* about the little ones either. To that goes much credit to him.

Here's my take, he wrote a book, I assume that took research.
 Then he tries to get the stock parts back for this bike, gets hung up a bit by a milled down brake bracket, leading to spacing problems..
 But me looking at it thinks, if he researched a bit, he would have ended up here, been able to quickly find what is correct... Possibly would have been able to trade for what he needs,  plus cash difference...would have been the easy way to do it..
 But I get the feeling he is being a bit greedy for what he wants for his stuff.. I mean realistically. It is old speed equipment for hat has been run a bit... So there is always the element of doubt, and lack there for desire to pay full price for used older stuff....coming from the buyers.
 Had he come from the start tohere, he may have been able to sell the whole motor,  which could have gone back together, but now it gets pieced out.

Yeah this guy is in way over his head.
Don't care how much he knows about 305s, he clearly doesn't know much about 750s....and even less about speed parts.

If I remember right he bought the whole bike rather cheap?  Something like $4k???
My bet is he thought he would make a boat load of money flipping it.
But now that has failed he feels trapped.  This trapped fish out of water is now flailing all over the place.
Sucks that a cool bike was killed and now this guy is lost.

yeah on the swingarm thing I don't know how you get sprocket alignment on the brake side alone on the f3,seems the sprocket has to move to get that with an early arm,hope the person who got it was not counting on an f3 bolt on,and yes too bad a cool old bike got parted out!bill

What do you have to say about that KMB?

Perhaps that double row sprocket set up was easier?

Hello All,
I now own the CB750F talked about in this forum.   I have the duplex final drive sprockets and chain if anyone is interested.   Also,  the bike in its present condition is an everyday rider with the engine that was de-tuned.
