MOPED ARMY

I have looked all over and for under a $180 I can’t find a way to do a yz60 kit with OEM parts. Would and OEM 60 head help out or is this just a situation where I need to quit trying to be different and get the malossi kit like everyone else?

Fresh powder!!!!

Is this pistons rings in the right spots? Top and bottom that is?

I like the black and blue so well that I think I’m going to have my control housings that go on the handlebars done in black and order decals to replace “stop” “start” “run” “horn” “hi” “low” and so on.

I am pretty happy with the way it’s coming together, I’m going to take my time the beat I can and do this thing up right. Over the winter I am going to tear an engine all the way down. Have the cases blasted outside, powdered silver, and have a really good looking ride. I need to find or modify some other metal fenders for this.

Any suggestions. For metal fenders? I guess plastic would work. I’d rather have sheet metal though.

Is it wise to powder-coat the head on an air-cooled engine? I would tend to worry about reducing the rate of heat radiation. A black head would radiate heat best, which is why heat radiators in electronic devices are black anodized, but that's not really a coating. Is a powder coating thick enough to prevent good heat conduction?

I haven't seen powder coating used in high temperature applications, now that you mention it. You're supposed to use an oven to set the stuff. I will readily admit that old, overheated, oil-stained bare aluminum is not the most attractive finish we could wish for, but cylinder heads on air-cooled engines lead a difficult life.

The cylinder head temperature on a properly-running Volkswagen Beetle air-cooled engine (40 hp, 1970) was 410 degrees F, according to the instructions on the cylinder-head temperature gauge I bought from JC Whitney around 1978.

As John Muir said in his iconic VW repair book, it is necessary to cool the burning heart of the beast that bears you.

Long long way to go, but I like where it’s going

I had this little issue and the seal went in to far on the right side, but my sleeve allowed me to fix it up.

Thanks to some awesome members here, you both know who you are, I changed both crank seals, honed my bore, set my ring gap, and have my carb ready to go.

I apparently have to purchase an impact screw driver.... then I can do my intake and reeds. But I’ve got a hell of a lot done in two days of work over two weeks(powder coat took some time.

Thanks PD, Thanks Again Jack

Far far from done but I am getting there.

How do you time these damn things?

Almost there

So if everything went back in smoothly after the seal change, I’m solid?

So I got a great engine(this far out of this rebuild)and the stuff all came back good from powder coat.

But now that I’m reassembling all the different components which I broke all the way down s well, I seem to be getting a very good idea of the utter torture this machine must have been run through. Things like brake lines, kick stand springs, hell a brake spring..... Even taking a good look at the tires and seeing the flat contact patches. No wonder I have a set of 99% condition Oem QT brake shoes, the first owner pinched the rear brake cable so hard it never worked again nor is it repairable with any amount of heat or beating, I did try some oil but realized I was wasting my time.

Either way I had to try it out so without brakes of any kind or a twist throttle, I ran some 60lb mono fishing line down the carb slide, tied it off and ran it to the handle bar where I made a crude pull throttle. I went for a little ride. The jets, port cleaning, and exhaust really did give it a good upper midrange boost in power. I used the old show against the front tire for a brake trick. There were no wrecks but I’m pretty impressed.

I took the drive shaft apart to paint the tube housing today, sure was a lot of chewed up black rubber coming out from the pinion shaft..... is there a seal inside that backwards hex key fitting I need to get changed right on out?
