Frame conundrum
« on: May 12, 2013, 11:15:51 AM »
I got a near complete 1978 Cb750K for a hundred bux yesterday!
It does not have a title and had no rear shocks but turns over and starts easy with great compression. Was missing tank and the seat but for a hundred bux , I figured there was no way I could go wrong.
Wanna make a "bratish" style bike like this one here somewhat minus the Firestones and maybe a super bike bar instead of the clip ons. Anyhow about the frame. Anyone know if a 74cb750K frame would line up in the neck area well with the 78K . I have a titled frame for a 74 and am thinking to just cut the neck off and have a bud of mine who is a pro do the transplant. I was thinking that would be easier than swapping everything else over the the other frame. What do you guys think>?

You think cutting and resetting a steering head would be easier, ?  I would have to disagree, just swap frames, far easier.  ;)

Much easier & legal to switch the frame.......but retain the K8 swingarm / chainguard to be sure the sprockets and chain have room.

To cut and weld and line up properly you would have to take them both apart anyway. No brainer, switch frames. I have cut and welded on them, lots of work and don't burn that paint, it will make you sick.
No matter how many times you paint over a shadow, it's still there.

Was always wondering about this lack of title issue?  Seems some states require a title otherwise your frame is toast.  In AZ I'm to understand you can take it to the MVD, post a bond and eventually get a title.  Why couldn't someone take the bike to a state that allows this, get the title, then transfer the titled bike back to their state?  I realize that's allot of time and some money but seems it would be allot cheaper then swapping engines, cutting frames, etc.

Well I have a 550k and I was thinking about doing the same thing with my frame and let me tell you I am glad I didn't because it was a breeze tearing down to the frame.

I undid the electrical up to the front end, removed the whole front end with one clean pull including electrical. That saved a ton of time. I would say I worked on it 4 hours and it was stripped bare.

One reason I went this route is so everything can be cleaned and painted if need be. In the end I will be much happier.

Have you ever been stopped and have a cop ask to see the frame number or engine #?

right ?!  i'm in a similar predicament, only i have a titled frame but the head has been attached to another [unknown] year/model, so i have frankenframe.  the welding job looks spectacular, but i don't want to run into a bunch of oddball fitment issues.  considering switching VIN plates to my unmodded, untitled frame and just redoing the stamped in VIN myself.    :P
