Short story... I bought the Santee frame from a kid that didn't know what he had, and the weld on little pieces are quite scary! I am no welder, but looks like he closed his eyes on some of the welds. So going to strip off all the "new" add on to the frame and make my own motor mounts.

I picked up the motor really cheap on Craigslist. The guy didn't want it any more and didn't know anything about it. He said he "tried" to see if it turns over by turning the kick starter. He put oil in the cylinders trying to "free" it up. I figured for as cheap as I got it, I could be still in great shape if I have to rebuild it.

Got it to my shop and it leaked oil every where as he had both cases off. Someone "tried" to paint them red. Looks like really thick paint or lots of coats of spray paint. They didn't even try to cover up parts of the motor when they painted. The shift shaft looks to have pliers put on them and screwed up the splines. I went ahead to see if I could turn the motor over from the crankshaft bolt. At first it just loosened it self, but rocked the crankshaft back and forth slight and it "broke" free. Now it turns over easily. I am pretty sure I will be putting new rings in it and possibly have it honed. In doing research on the motor I found it to be a 78-79 Special.

So here is a picture of then engine mocked up in the frame. As you can see it is not sitting right in the frame. I am wanting to put a 21" front rim with an 18" rear disc. Looking also to have my friend help me make a girder front end. I have very crudely photoshopped of how I am envisioning the final look. I already have the gas tank.

Any input is greatly appreciated. I will be asking several questions on the way.

(Also this build will taking a while, as I have a gs1000 cafe project I need to complete, along with my life long "old car" build)

Well I was finally able to get to the shop to do some work on parts. Should have been working on the GS, but oh well. Took a while, but got the engine covers looking pretty good. Now I have to decide if I want to powder coat them super chrome or keep sanding/polishing them.

But of course take a few step forwards and one back. On cleaning the carbs, I broke one of the posts of the float pin. Don't think I can epoxy it back in? Or can I? Anyone have any luck epoxing a post back in? Also I did try the tricks to get it out, use socket on the other end, heating the pin, but ultimately it broke.

Here are some pictures of the progress, and one of the carbs painted and baked/cured.

Well just scored a "pile" of carbs on ebay. Hopefully can make one work and maybe some correct jetting bits too (wishful thinking).
 
The slide cutaways are shallow, makes for rich mid-range.
If you do a forum search 'cutaway', you'll find about 33 threads to wallow thru for info...

I was able to get some 2.5 slide cutaways the other day. Still will do my research, I am far away from needing the carbs.

Thank you for the info.
