The tank was the first thing that was worked on...

It was cut open, blasted inside and out, and resealed. All work was completed by Moyer Tank Restoration.

Body work and Paint was completed by John Hartnett.

All Emblems, and trim will be replaced with OEM.

The paint is a version of the original Candy Bacchus Olive. We took out some of the candy and gave it a darker more metallic tint.

The frame was the next...

All of the black pieces were stripped, sandblasted and given a two stage, black epoxy paint.

Ill post some more of the build later....

Nice! I have a green '73 that will be getting that treatment perhaps next year.

I really like how that frame came out 2 stage epoxy? Is that as durable as powdercoat? What kind of cost would I be looking at to have my frame done like this.

Thanks!

I chose the epoxy because it looks great and corrosion protection of epoxy is hard to beat. The other reason i picked an epoxy is because its easier to touch up. If you scratch a powdercoated frame its tough to fix and I plan on driving the hell out of this bike.

The total cost to powdercoat was a little bit less, I think about $150 less.

youn6372 · « **Reply #24 on:** August 24, 2011, 07:08:35 PM »

We finally got the motor into the frame, hooked up the gas tank, and threw in some oil. The bike started up on the second kick and it started on the electric start before a short in the hand control smoked up. It hasn't run in 17 years so its a great night. We have some finishing touches, then the first 20 miles to break in the new pistons and rings. Cant wait to ride it!! It sounds great with the MAC 4 into 1 but the quality of the MAC is terrible.

rickmoore24 · « **Reply #26 on:** August 24, 2011, 08:08:38 PM »

I agree about the MAC. I have one myself and I don't really care for the sound, look or fit. But it was cheap. LOL Again, really nice build.

tango911 · « **Reply #27 on:** August 25, 2011, 05:57:44 AM »

great job on the paint. looking awesome.

CBNJ74 · « **Reply #28 on:** August 25, 2011, 09:12:04 AM »

Wow man I'm speechless. I just picked a a green 73 with 15k on the clock last month. Over all it's in good shape for it's age. I've been cleaning it up here and there. Would it be rude to ask the costs involved in accomplishing a build like this? PM me if you like.

youn6372 · « **Reply #29 on:** August 28, 2011, 04:02:50 AM »

Well I drove my project for the first time. I think its safe to say this bike hasn't run in at least 10 years. A few things need to be addressed like the brakes, the horn, the positions of the controls, and the oil return line developed a leak and got oil everywhere.

Im still waiting for my restored speedometer and tach to be returned to me, (Bobs in Howell Michigan......)

It did sound wonderful and had plenty of power. The Pirelli Demons were nice and got scuffed a bit and we are closer to breaking in the pistons and rings. My ride was short (oil) but the problems are minor and we should be finished, after this stupid "hurricane."

chewbacca5000 · « **Reply #30 on:** September 04, 2011, 05:29:37 AM »

Good job! Bike looks great! Where did you get the tank decals, the ones that go around the black area? Thanks!

Prospect · « **Reply #31 on:** September 04, 2011, 07:40:38 AM »

very nice job. Paint looks fantastic. How long did this restoration take?

gto_ron · « **Reply #32 on:** August 06, 2013, 12:03:47 PM »

Just read your thread, you do really nice work.

youn6372 · « **Reply #33 on:** August 08, 2013, 06:47:01 PM »

I wish I could take all the credit. I had some very talented people working with me to see this project through. I recently put a CX-1 cam in it and I'm working on the carbs. Its a blast to ride.

dooger54 · « **Reply #34 on:** August 08, 2013, 06:56:43 PM »

I'm restoring the exact same bike, even the same color. Was planning on getting the Mac 4 in 1 also. Did you consider any other exhaust?

I actually have an original set that are in storage. I also have a cool set of Hooker 4 into 2. I put the Mac on because it was cheap. I figured in a few years when it was discolored and old. Ill buy a new one and replace it.

CBNJ74 · « **Reply #36 on:** August 20, 2013, 12:52:29 PM »

I have the MAC 4 into 2's on my exact same year and color bike. I've been pretty happy with them.

youn6372 · « **Reply #37 on:** November 15, 2014, 07:15:06 AM »

Its still looking great! Thank you to everyone here (Bill Benton) who has helped me keep my SOHC on the road.
