I know they dont make hardtail kits for my 71 cl350 besides i want to custom make my hardtail anyway. My question is does anyone know how or a guide i can use to build my frame jig? I plan to mock everything up and tack it in place real good so nothing moves and mock everything up make sure it fits, take it apart and take it to a professional to be welded and then piwdercoat it. On another note. Could i make a soft tailed bobber out of a cl350 without too much work? Railroad crossings are abundant here

I found this on the goggles. I have no experience modifying frames.

I've done that. I now have a jig, but I used to use the swingarm. It really works best if you want to stretch it several inches. Simply weld your swingarm solid then weld your new axle plates to the rear, then put in your frame rails. I'll try to find an old thread to link. I don't have a thread here on that build.

Here you go... I don't claim liability for all the misdirection it may cause, that was one of my first builds. The basic theory is sound though.

Is yours one of them without a cradle under the engine? I've seen them done too.. Can probably dig up a thread somewhere

Is something like this what you had in mind:
This was one of the bikes I got in a package deal with another CB350.
The rear of the frame had been chopped and the PO had a hardtail subframe built. It bolted to the swingarm pivot and motor mounts. Upper part needed to be welded to the frame.
I decided I didn't want to go in that direction. Removed the hardtail frame and sold it to another DTT member.
I can post other pics if you want.

I don't like stretched frames so I kept the swing arm in tact on my bobber. I just welded it solid. This bike rides down the road great, it's comfortable and handles great. The sprung bicycle seat adds a decent amount of bump protection.

Hardtailing a cb350 frame is a NIGHTMARE. You're better off finding an SL frame to modify or... Find a prebuilt hardtail frame. Something for a twin (Triumph, BSA, etc...) and change the motor mounts to fit your engine. The stamped steel CB frame is just not designed to be anything but what it is.
) but PLEASE don't use the swingarm as part of the hardtail. There are a number of reasons why you shouldn't. I won't get into all that and clog your thread up, but... Do it right.

Thats actually pretty clever... Similar to the Triumph and Sportster "bolt on" units. Still dont trust the stamped backbone as a mounting point for a hard tail though.
