A little bit closer every day. I have to go grind a groove in my rocker shafts and then I can torque the head and get this back in the chassis.

I wasn't sure at 1st about the all black on the older motor having a shiny one myself, but  have to admit it looks sweet. Good job.

Big fan of the black too.  Impressive

Thanks everyone for positive comments.

The all-black look is reminiscent of the early 80's Yamaha 'Midnight Specials'

Even Triumph now is making an all black motor. Would it surprise you guys to know that at least the cases on this motor my brother did in black over 40 years ago. I've just take it a step further and blacked out everything in varying shades of black. I think the paint scheme and the rest of the bike are going to tie in nicely.

Be careful where you park it at night,you don't want a parking lot incident.

Did carbs go through full baking after coating? If so, did slides move nicely..?

Yes they did, not 10 minutes at 400°, but 15 minutes at 375°. They slides move freely in the bores. I don't foresee any issues from the coating process. Anything less than a full cure could possibly see issues up the road with contact with fuel spillage. These castings got nowhere near deforming from that low heat.

Hey powderman, I got some kz650 powdercoated engine covers that have been discolored by fuel...think of anyway to polish it out?

[Powderman]

If you can wet sand the discoloration out you can cut and buff just like if it were paint. After you do that and clean them thoroughly put them in your oven at 400°f for about 20-30 minutes. I suspect your parts were not fully cured if it's discoloring from fuel contact. Actually i would secure it in the oven after wet sanding and before cutting and buffing.

I will try it.  Thanks

Ready to go back in the frame.

good for you

Gorgeous looking motor, and totally digging the black. Carbs came out excellent!

Thanks, can't wait to get it back in the frame and making some more progress towards completion. Needs about $1k and I just don't have it right now.

Looks fantastic, Powderman. You are making me want a Triumph...

[ken65]

Very smart. Looks good.

Had this finned rocker box oil cooler in the box of parts and went to fit it to the rockers only to find it is for a pre unit 650 that doesn't have fins on the rocker box. Fins got in the way of it fitting up against the box. I had to chuck it up in the mill and machine the back side to fit the Bonny head, it ain't pretty on the back, but it can't be seen and I was of course going for function over form.

[Powderman]

Details, details, it's all in the details.
My new grip was too short for the existing throttle tube, so I had to machine 3/8" off the tube. Also the tube being raw aluminum and the grip being transparent threw the color shade off from the other side so I had to powder coat it black to match.

Before:



After:



I couldn't find any spacers locally so I cranked up the bench top lathe and made the spacers to locate the caliper brackets on the lower legs. They are now ready to weld to the lower legs.

[754]

I hope the piece you are planning to weld is bigger than that..like a long piece, that goes to both bolts..maybe wider on the weld edge, to keep the heat and distortion from that mount area.

I have a source for excellent TIG welders that understand my need to not distort the tube from welding. I may have to go in with my hone afterwards, but I expect that and see it as no big deal.

The bracket should be substantial enough for the job. 5/16" by 3-1/2"
