    I agree! You could start with a CT200U.

    Good idea because parts are scarce.

    Inverted Manifold for Mikuni carb?

    The fog was reversion, and your question about mild cams, yes, they are wide LSA, short duration and mild lift for the same reasons. They are better over a wide RPM range, hence "general purpose". The choices we have are to adjust plenum volume, valve overlap and header size and length to...

    Ohh I’m kind of exited Japanese 2 stroke??

    Be patient. Go away and find something else to do. Today is the first. Pour some kind of oil on it and come back on the 14th.

    Another vintage trike mower!!

    It looks more like an oriental flower bouquet holder, so you can pick up dandelions as you mow.

    Another vintage trike mower!!

    Do we have any guess what that is between the steering handles?

    Tire Changing Rig

    Wrap a ratchet strap around them. Crank it just until the beads touch. Use low pressure to seat the beads or you will need to remove the valve core to remove your strap.

    Got a link or a picture? One of those would make this thread a whole lot more interesting.;)

    Ohh I’m kind of exited Japanese 2 stroke??

    Crank is not pressed into the case. The crank might be two pieces pressed together at the rob journal. Don't worry about that now. Once you get the piston moving, rock the crank back and forth, see if there is any slap, knock, looseness in the bottom end. If not, you probably don't need to take...

    Inverted Manifold for Mikuni carb?

    Valve overlap is the amount of time, in crank degrees that both valves are open after the exhaust stroke. If everything is tuned properly, the exhaust leaving the cylinder, into a tuned header, the exhaust will continue to flow after TDC because, remember, air has mass, and once you start it...

    What is the fuel for that fire? Kerosene?

    Ohh I’m kind of exited Japanese 2 stroke??

    Forgot to mention: Using Coke is OK, BUT if you don't get results or if something else comes up, or if it takes a long time, or, for whatever reason, you let the coke dry in the cylinder, now, you have a sugary varnish mess to remove before any oil can get to the rings.

    Ohh I’m kind of exited Japanese 2 stroke??

    I ventured into wine making during the 2000's. An old guy told me never to become discouraged and never rush the process. He said " The greatest virtue of a winemaker is patience". More heat is rarely the answer. The same advice goes for anybody messing with ancient equipment. It took years for...

    Inverted Manifold for Mikuni carb?

    Here's an interesting fact to ponder: Air has mass, even without fuel in it. As stated be @ole4 , curves in the runner cause the air flow to become disrupted. Here's a rough description of another fact. With your throttle open and your valve closed, pressure in the plenum or runner is trying to...

    Ohh I’m kind of exited Japanese 2 stroke??

    Coke is good. Patience is best. I mess with a lot of old farm junk, and the best ring solvent I have found is trans fluid. New, used, whatever. On the smoke motors, you can pour it in the intake and exhaust, too. The piston is also both valves. Fill the case with it if you have enough. Since you...

    Clinton Panther parts lot

    Did any of you folks bid on this pile of parts? I don't want to deny any of my forum friends these parts. If you want them, bid on them. They are not mine, but I am a Panther hoarder. :eek: If nobody from here lets me know they have bid, I might take it on Saturday.

    Inverted Manifold for Mikuni carb?

    Look at a trombone for ideas. Maybe a couple of O rings and a set screw to hold it where you want it? I agree that cam timing will be a factor. This might only adjust the intake runner to adjust for camshaft valve overlap. Interesting idea.
