WOW, brings back memories as I owned one of these about 1972. Mine was tricked out with preston petty fenders and a Hooker expansion chamber Yours is in great shape.

Hey Lou, it is great to hear about memories of dirtbikes and riding, they never go away! That is really cool to know you had a 72. I think back of all the fun I had on a dirtbike and I could write a book!

Regards,

Scott

Wow, nice bike. I had a a '74 TS 125 Suzuki - my first bike. It had a "down" pipe. I can't believe we used to ride these things on trails. And this is a rotary valve intake, too. Very trick at the time.

Hey Frank, I was just reading in either Dirtbike or Dirt Rider about KTM working on rotary valve 2-strokes. They suposely are much cleaner running machines and that would keep the goverment at bay and we can still have them around.

Regards,

Scott

I'd like to see how they do that. The big emissions bugaboo for 2 strokes is the total loss lubrication system, either pre-mix or injector. This can be partially solved by having the crankshaft bearings lubed by a separate, recyled oil supply but the rod bearings still need lubricant. Direct fuel injection can help with fuel-based emissions and cut down the unburnt fuel in a two stroke. A rotary valve is a more positive sealing device than a reed valve, since it is mechanical. Maybe that's what's needed to to work with the fuel injection.

Still, adding the intake to the right side of a modern, liquid cooled, power valved two stroke, plus a lube system, makes that a pretty busy place. The intake would likely be on the left side.

Did anybody here ever do a "port job" on a rotary valve intake? Meaning you filed the opening bigger to increase intake duration.

Hi Frank, I thought I read somewhere that someone did that on a snowmobile motor.

My 84 Can-Am ASE 250, as an option from the dealer, you could buy different OEM rotary valves.
