1970 CB750 Frame Question
« on: February 03, 2009, 04:25:33 PM »
I have a titled (not in my name yet) 1970 CB750 frame that came surrounded by parts from various year bikes. The bike is currently apart in preparation for conversion to a cafe racer. My question is are '70 frames rare? As in too rare to cut off the passenger peg stays? I would hate to destroy something that may one day make a comeback.

The purist will no doubt want your vin or serial number to determine value.  It may very well be worth more than the run of the mill 74

I am out of town for a month, but I ran the numbers on the frame and engine to see if I had something that may be worth restoration. After determining that the gauges were not correct for 1970, neither were the headlight ears or bucket, along with a few other things. I realized that trying to make 1-1970 would be financially challenging for me, I would be better off picking up a complete bike....

Here is the post where I was trying to determine the pedigree of mutt I have: http://forums.sohc4.net/index.php?topic=28198.0

why do you want to cut off your passenger peg stays? Most exhaust systems and rearsets acutally use those to mount (not to mention the centerstand stop on most aftermarket exhaust systems). Is this just a fit of overzealousness or do you actually have a plan for the bike and hanging the exhaust and your rearsets?

of the top of my head I would say hack up a later frame, the earlier frames are worth more.

I plan on going with a minimalist exhaust theme... Either a 4-1 that turns down and out-ish at the collector or the 4-2 that I currently have and turn down and out-ish at the collectors, so I will have to hang them somewhere there in a manner that gives them some limited motion. The details will be created on the spot. As for rearsets, I am going to fab a piece that welds directly to the frame. Center stand? We don't need no steenking center stand. I do understand the usefulness of a center stand, but on this one it has to go.

I would prefer to use a later frame, if there is someone in the Houston area who would like to swap a titled '70 frame for something later (titled), I am all for it.

I picked up an early 1970 frame for $20 and e-bayed it to a sandcast freak for $325. If yours is an early type, sell it to someone who wants and will not hack it and buy another later parts bike with your profit. There are tens of thousands of later frames available.
Everyone is happy.
