Tracker-ish cb550
« on: Mar 13, 2019, 00:18:32 »
So I bought a Ď76 cb550 a few years ago that came with a titled extra frame. Iíve slowly been gathering parts for it and thought it might be time for a proper build thread. Progress will be slow with a wife and kids that take priority, but Iíll post updates as Iím able to make them.


I scored a nice set of triumph Daytona forks for cheap and wanted to use them on this. Threw on an old xl350 (I think) tank that has been laying around for years, and Iím excited to use it. I also got a wheel setup and swingarm off a cbr500. Hereís how she sat for about a year until the past few days when I grew a wild hair and decided to jump back on this thing.





Lopped the back end off and started to work out a new one. Nothing like a toilet paper prop to get angles just right...





Tacked in. Figured I had to get this part set, angled, and centered so I had something to aim for with the supports underneath.





This is the new support. Nailed the notches even without a tube notcher, but making another to match on the other side has been a pain, haha. Iím super close, but itís quitting time once the kids are in bed, too loud doing this stuff in the basement!





Thatís it for now.

Bruce comes home from the pub and sees Sheila watching Gordon Ramsay's F%*#ing cooking show on the telly.
Bruce says; "What are you watching that shit for? You can't cook to save your life!."
To which Sheila replies; "So what? You watch porn movies, donít you?"

Thanks for tuning in guys, I appreciate the interest! 


I got the second side of my subframe cut to match using a handy little trick. I rubber banded toothpicks all around the support tube and slid them up until they touched the upper frame rail. Once they were all touching, I secured them in place with tape and was left with a perfect template for the notch I needed to cut.








Slid the template down, traced it onto the tube, and viola, the results speak for themselves. Iíll be using this method to cut my compound angle notches from now on.







Next up is the two front supports that will tie into the front of the new frame hoop and the backbone.

Genius. That would have saved me a ton of "refining" on mine. Definitely writing that one down

I canít take credit for it, I YouTubed how to notch tube and came across a guy who did this with welding rod. I donít have any of that, but figured toothpicks would do the same. Those I have haha.

That's a neat trick for the tube notch.   I know somebody else will say it but you need to check tire clearance at full shock compression on that straight tail loop.   It's a detail that bites many in the butt.

Yes, I am often in awe of brats, cafes, etc that I see with just a couple inches between the tire and hoop/fender. Sure it looks low and mean, but how the heck are they not slamming on the rear tire?  I definitely had that in mind when setting my angles, and Iím still planning on an upsweep on the back to increase clearance, just havenít done it yet. I think Iím going to end up cutting the back of the hoop off and welding it back on at a steep enough angle to create a pocket for the rear fender to nestle up into. Hereís a little photochop of what Iím thinking. This should give the rear a bit more clearance still.

Good call on the kickup.  IMHO they look way better  too. 

Most of those slammed bikes seem to have the suspension set so stiff it might as well be a hard tail.  Either that or they don't really ride them at all and it's for the Instalikes.

Haha, yeah, I think the gram has a lot to do with it! I built an xs750 for a guy a couple years back and he would often send me pics of bikes he found on Instagram and ask if we could do something similar. I had to burst his bubble more than once and say yeah, we can do that, but it wonít be rideable anymore haha.
