Hey guys, I've never documented a build here but I'm getting pumped about this one. A friend of mine gave me a motor from a 75 cb550 that is in great shape so I began looking for a frame. Ended up coming across an 82 cb650 nearby for $250 so I got it on Saturday. The guy said the motor had been siezed, he got it going again, then it sat. Just starting to tear into it when I have time. With any luck the motor will work for the summer and I can do a full swap over the winter. I will get some pics of the tear down later.

I was looking at those. Their weld on hard tail kit might be my winter project. Very affordable if you get the unassembled one.

Write up with pictures of how to do the full hardtail kit right.

I will repost it here as the full write up then.

Thank You Alex Christian for showing and allowing these pictures of a proper way of doing a hardtail kit conversion.

First he braces the motor mounts. [Figure 1] Figure 2]

Next he clamps the 2 lower rails so not to move. [Figure 3]

He then adds supports from the lower rails to the back bone.

Now he has the frame ready to cut the rear section off to his lines.

In these pictures you see the tail section removed.

He now slides the new tail section in with a support at the rear axle plates.

He bolts it to the rear mount plate he welded in earlier and straps the two pieces together. [Figure 10] [Figure 11]

He now uses a Jack to straighten the back bone vertically.

Now with a laser line he checks the back bone is straight horizontally.

He now tacks and welds the rear section on checking for straightness again. [Figure 14] [Figure 15]

This is the finished product.
