Here's the saw coming apart for measuring the port timing.
That would be fun, except the 441 I did is in NY It responded tremendously. I was very pleased with it.
That piston is wild looking!
Nice to see the Germans are getting a sense of humor! :hmm3grin2orange:
Pretty darn exciting if you ask me. Dealers don't even have these on their shelves and here is one in Ohio being disected!
Don't get more cutting edge than this!
Thanks Brad.
In this pic you can see how progressive the transfers are front to rear. I think I understand what they're doing here. By opening the intake side first, the pressure is higher on initial opening, and all of that pressure is directed to the back of the cylinder, and then progressively moves forward. I'm thinking this is an attempt to more positively purge the exhaust from the cylinder. Instead of opening the transfers all at once and "blasting" the exhaust out, it's being pushed out from the back forward. Make sense?
That is standard two-stroke scavenging. That is why they are called loop scavenged. Up the back, over the top, and down the front.
