RE: Saito 125a
[size=2[font=Just wondering about the muffler , i love the new saitos and i have the 125 myself still new in the box. The only thing i dont care for is the muffler . The older saitos were much better sounding and a little more throaty sounding. How is the restriction in the 125. I plan to use the Perry pump on mine and run without muffler pressure .

I have no doubt that there is a couple of hundred more rpm available when I get braver about peaking the mixture, I just took it to near the end of the rapid rpm increase range when I took the reading.

RE: Saito 125a
Dave,
I get a kick out of people saying they are afraid to momentarily check peak of an engine even after they have 1/2 gallon of fuel thru it.
How can you tell if it's broke-in if you don't check to see if it will hold a peaked needle setting?
I run a ringed engine blubbery rich with extra oil added to the fuel, flushing it for five minutes, then proceed to thermo cycle it several times, leaning it progressively, checking the head temp with my fingers. After about five heat cycle runs (cooled completely between each run) I'll check to see if it will hold peak without sagging. If it doesn't I'll quickly richen it several hundred rpm to cool it off. Do a few more heat cycles and check again. Running a engine blubberly rich helps the con rod but does nothing for the ring fit, sure does make a mess in the yard though.
I use a 1" smaller prop during break-in to keep the load down which keeps the temp down and prevents damage during the initial peaking operations.

This is my 11th Saito from .30 to 2.20 and I haven't ruined one yet. Our methods differ and accomplish the same thing. My personal opinion is that Saitos can't benefit from heat cycling.

RE: Saito 125a
Dave,
I know you love engines and I'm sure yours will last as long as anyones.
I think many people use more fuel to run them in than required, that's what I was trying to say.
The way you run them in makes you happy, the way I run them in does it for me. We both enjoy the hobby.
