The matte paint on the frame is nice.  That shock is shot.  I would just buy a set of Hagons for it.

Would these work? They are an inch shorter than stock.

For unknown reasons, you picture is not coming through on my browser.  The image link is for an Emgo shorty shock.  The Emgo stuff is cheap but I would not use their shocks.  If you have stringent budget issues, look at the Hagons or even the Progressive shocks.  A shorty shock will also disturb the handling of the bike.

Thanks!  Where would you recommend buying Hagons from?

Got almost all of my new parts, still need brake lines and throttle cables, and going to start putting it back together. Planning to lay my engine sideways and slide the frame over it bot it on, put forks on, pop the center standout the swing arm and wheel on. Then everything else. Anyone got a better way of putting a motor in a newly painted frame that will reduce the risk of scratches and be kind to my back.

Hire 3 burly men? I think your method works like a charm, actually. Apply some blue painters tape to the frame while you wriggle the motor in to protect the paint.

before you strap all that back together, make sure you have bare metal or the battery ground to the frame, and between the motor and the frame. It does make a difference in your electrical system and charging.

Just for the NEG strap. On the 550/750 the NEG gets pinched between the mount, frame and motor. Not 100% on yours, but if so, clean to bare metal that lug on the motor, and the mount.

Gas tank stripped and coated in rust neutralizer


All cleaned up


Caswell liner curing


New All Balls roller bearing races installed


Installing bearings


Put old bearing race on the new bearings, placed a 1 1/4" galvanized pipe on top of that and hammered away on a piece of oak to press new bearings into place


Removed logos to sand and paint side covers.  Found CB350F shocks on eBay for $20, cut down spring guard, and painted the springs.  Should have plastic dipped them but I didn't want to drive to the hardware store.

Spokes look a little battered up from rust. No plan to replace them?

Also, be sure to leave a bare metal "ring" around the top of the filler cap. That prevents the fuel from seeping under the paint and lifting it off as it comes down the filler neck. I generally tape off about 1/4" from the top, then sand it to fully bare. Spray from there down to the tank body.

If you are not going to replace the spokes, you may want to remove the oxidation with scotchbrite pads and steel wool, and then clear coat them for protection.  This assumes that the oxidation is only superficial.

Replaced the wheel bearings and almost finished up with the wheels

Removed the bearings out using a concrete anchor


Front wheel bearings removed wedging two screwdrivers and the bolt from the anchor I used to do the rear wheel


Improvised tool for retainer ring


This works too but resulted in some blood blisters when it slipped


Front done


Rear bearings out


Done



Now to rebuild the front brake, fork seals, shocks, swing arm, and put the wheels back on

Finally Got the forks apart.  After several recommendations I went and got a $20 torch and had those stuck bolts out in no time.  Had to get them fairly hot but it worked!







One more coat of primer needed before final wet sand and topcoat

So heat it up and cool it down in water?

HA! With my allergies I couldn't smell a thing but my kids both said "that smells like poop" dropped their screwdrivers and ran inside LOL

Painted side covers and tank. First, is a good shot of the tanks lines and second is a shot that shows off the metal flake.
