Painters fancy themselves "Artists" and thus time is of no relevance to the gifted!

July 16th update: stopped at the painter today and all the tins are done except the gold stripe he paints on the tank. So here are a couple pics of the blue / green. Now don't get upiddy...it is so hard to get the blue / green to show up nicely with the camera. Got the PPG code from a member here and it was identified as the Honda blue green. It looks dead on in person. So we are getting closer. I will pick up all but the tank tomorrow.

Yah, Jerry you know first hand the kind of job Joe does here. It is that nice. Now add that gold stripe to the blue / green...wow. She should stand out nice. Getting antsy to get this back together and on the road.

That all depends on the clear coat used. The paint itself is not fuel resistant at all.

Update July 25th - got the top of the air box installed, ears and front fender. Nice to have some color finally on the bike.

Stev-o · « **Reply #209 on:** July 26, 2014, 11:46:46 AM »

Looks great Johnie. Did you put the wheel on first and then the fender? I find it easier to put the fender on first.

Old Scrambler · « **Reply #210 on:** July 26, 2014, 06:32:40 PM »

Looking Good...........as expected from a pro

Looks like you and the bike might be ready for a ride around the lake on a sunny day in September. Let me know when your up for it.

Johnie · « **Reply #211 on:** July 26, 2014, 10:42:52 PM »

I changed it up a bit this time Steve-o...I put the wheel on, then the fender without the stays. Did the stays last before I had the fender tight. That way I could get the fender on without the stays scraping around on stuff.
Dennis I will let you know when she is ready to ride...

June 9th - time for an update - the 72 CB350 is done except for the OEM mufflers which will go on soon. Now I can get back at this KO. I had painted the frame in front of the motor a couple weeks ago. This past weekend I got the side covers polished and the KO back on the lift for the final assembly. Put on the newly painted center and side stands. Glad to get back at it...

As usual, looking great Johnnie! What method & tools have you found works best for polishing when you keep the engine in place?

Johnie · « **Reply #213 on:** July 27, 2014, 06:48:26 AM »

Thanks Dave....I polished the engine side covers and valve cover with a 6 inch cotton buffer and rouge. Works good and gives a nice clean look.

Still doing the Red->Green->White rouges in that order? I'm getting close to start buffing my covers....

May be a foolish question, but it's chucked in a cordless drill, right? Just have a couple charged battery packs & off you go?

Johnie · « **Reply #216 on:** July 27, 2014, 06:30:14 PM »

Dave...my first tip would be to forget the drill and get a good buffing wheel. I have a 6 inch Craftsman bench buffer I use. You need to get the alumimun hot to let it flow a little when you are buffing and a drill will just not generate that much heat. That being said, if you want to use a drill you may get some nice results but not as good as a bench buffer. The first thing you should do is use a chemical stripper to remove the clear. The red rouge will take it off, but it does take a while. It is much easier if you let the stripper get it off for you. But go ahead and experiment with it. The red rouge is a rougher system which will cut faster and deeper. The green rouge will take out the marks from the red. The white will take out the finer marks from the green and give you a nice look. When done some guys clear it again, but I never clear as I want to be able to touch it up whenever I feel like it. However, I have never had to touch it up with the wheel. I just use Semichrome or MAAS polish to make it look great again. A caution for you, use safety glasses and a dust mask as it is dirty work. Plus, a good thick work glove as the aluminum gets hot. Take your time and let the rouge do the work. Use one color rouge per wheel. Do not use the red wheel with green rouge. You do not want to cross contaminate the buffing wheels.

You can usually get the 1/2 HP buffing wheel at Harbor Freight fairly cheap. +1 on some thick leather gloves to handle your parts, as the aluminum gets a little toasty with friction.

David B · « **Reply #218 on:** July 28, 2014, 05:59:01 AM »

Ok, that makes more sense. I picked up a buffing wheel this spring and am figuring out what works best. Your tips help with the learning curve, thanks guys. For some reason I thought you'd done all that polishing while the parts were still on the bike. If that was the case I was pretty impressed and wanted to know the trick!

Johnie · « **Reply #219 on:** August 03, 2014, 06:49:03 PM »

Update - August 3rd - got the bottom of the air box and overflow tubes installed. Cleaned some oxidation off the 5 prong male connection and put dielectric on it. Checked and cleaned the other connections. Got the bucket, blinkers, handlebars, levers, cables, MC and gauges installed. Connected the bucket wires and found a broke female ground which will be replaced tomorrow. Left to do is install the carb slides, plugs, new plug wire ends and the battery. Waiting on the gas tank from the painter as he is painting the gold stripes. I have an extra tank to use if I am ready to fire it up and he is not done.

The plastics look so nice! I bet you can see your reflection!

Johnie · « **Reply #221 on:** August 04, 2014, 08:06:45 AM »

The gauges...when I did the red KO in 2007 I ordered the Yamiya faces and covers as LeCram was not around yet. Never can go wrong with the Yamiya stuff. This time I thought I would try LeCram so I can compare. For this current KO I decided to use the original faces since they were in such nice condition with no warping. The only fading seems to be in the red zone which I can live with. I am not after a concourse here. In comparison, the Honda covers and Yamiya covers are a bit thicker than the LeCram covers. So when I put the LeCram covers into the gauge holders they would not tighten down. To remedy this I had to modify an extra set of gauge rubbers to make up for the lack of thickness on the LeCram covers. Once I doubled the rubber thickness they would tighten down fine. The other thing I noticed in comparison of the faces, Honda and Yamiya have the cut-outs for the miles and trip meter painted black on the inside lip. The LeCram has those areas unfinished plastic color. Not a big deal unless you are after the way it looked OEM. I was just going to use a black sharpie to paint it.

Looks great Johnie! Take a pic out in the sunshine so we can see the green in it.

Johnie · « **Reply #223 on:** August 10, 2014, 07:52:19 PM »

Yup...getting close to getting it outside for pics. Still do not have the tank back, but soon...I hope.

Johnie · « **Reply #224 on:** August 15, 2014, 10:47:24 AM »

Update August 15th - Got the KO running this morning. She is a "rainbow" bike as I have a spare gold tank on it, red side covers and blue/green everywhere else.

Painter says he will have the side covers and tank back to me by the end of the month. I did take a video and will try to post it later, but for now here is a pic of the "rainbow" bike. She is not getting fuel in #3 so I have to check that out. Bowl is full & spark is good. I did take it down the road and she shifts smooth to all 5. Actually runs pretty nice for only 3 out of 4. So now comes the fine tuning.
