Pete,
The muffler appears to be a TH12x1A TurboHeader for the Saito 100 and others. The Saito 80 uses the TH12x1B that has a ring machined in the neck to tell them apart. It will probably work okay but you will not get your best performance if it is the A model. Thanks for picking up one of our TurboHeaders. Send me a message if you have questions. You found a great bargain.

I did not tach the engine. The winds out we gusting to 40 mph. Thanks on the test stand and the field cart. The test stand was built from scrap lumber I had around and coated with spar urethane. The spar urethane is fuel proof after sitting a couple of days in the hot Texas summer sun. My field box on wheels has one special feature. It has a 20-watt amp and speakers that I plug my MP3 player into. I can listen to music while I fly. Nothing like listening to the Beach Boys or Buddy Holly music while you are flying. Did I show my age with that one?

I picked up two of those mufflers at the swap meet. My plan was to use the other one on a Saito 65. They are sure a piece of art. Do you not recommend using them on the 80 and 65?

what the????
well I started typing another post, was going to tell you that the guy that sold me this GK100 said he ran it really rich, so I was going to show the valves and how black they are. but I found something odd to me. both valves in my Silver FA100 are the same size. but this GK100 has 2 different size valves. the E-valve is the same size of a 91valave, and the intake is a 100 valve. just looking at the valve ports you can see the Exhaust side has a smaller valve port ID. LOL did someone make a BooBoo. any one here seen this before??
BTW, my manual show me both the Silver 100 and GK100 have the same valve part number. oop, too add, I have a set of 100 valves I bough from Horizon and they too are each the same size.
see how black the valves are, and you can see one is larger.

The valves should be .428" exhaust and .468" intake. The .91 is .428" for both.

With a lot of flying, my fuel with Klotz Super Techniplate (20% castor) will make the exhaust valve black with a lot of carbon build up. If you put the valve stem in a drill press chuck at low speed and spin it, Scotchbrite will clean them very nice.

The steel wool and Comet are for cleaning the valve, not actually seating it. And then, carefully when cleaning the actual valve face.
Dave, you had me scratching my head!
Never saw an engine with an exhaust valve larger than the intake. An easy slip up though.

The Gypsy Queen is riding with me in the mom mobile on this cannonball run. If i put a big can of fire hazard in there she would probably hit me with the iron skillet she keeps around in case I really cheez her off....
Could put a rack on the hitch but that would guarantee getting rear ended by a distracted driver LOL.
Ok Guys. The grilling may start now😉

Using the 5 gallon, steel VP M-1 empties. Pretty stout cans and already properly labled.
I buffer in between the cans with styrofoam and secure well.
And yes, a sharp eye in the rear view when stopping. Something all surviving motorcyclists learn about
That keen eye as well as keeping a viable escape path ahead, even when it means stopping a car length behind the car ahead. I know you know what I mean.
That gaspoline in the tank is even easier to light!

Could leave the Queen at her throne.
The Norwegian Princess would certainly allow me a leave along with the Royal Coach. She is very well atuned to the methanol aquisition runs.
Considered a tax-exempt, environmental mission. After all, not a fossil fuel.
Plus, flying keeps me away from the Castle at times for many days in a row.
Then again, we could make a separate side trip sometime.
How huge is your new plane?

when I took the FA91 apart I used Versa Chem Metal Compound on the valves to clean them and it worked very well without hurting or scratching them. I used Versa Chem Metal Compound on the valves because I had more of it than the Clover.
as for Seating Saito valves I have read here on RCU somewhere that people have used gritty toothpaste, but I sure don't know how good it works????
sorry for the edits, its rather dark here and hard to see the unlet keyboard!

Yep. That's what I was thinking to Gary. Forgot the pencil eraser face clean up. Slightly off topic, but how are you transporting that cheap methanol. I am heading down to Alabama to pick up a plane. Thinking bout filling a twenty gallon steel drum on the return route.

Rules vary by state, some by weight, some by volume. Most allow for 4 approved cans of five gallons. That is what I have been using as a guideline from PA thru OH and into MI.

As some of you may know I have a scratch built Ryan SC-W build going on over at RCG. I have been thinking about servo locations and was wondering if a micro servo mounted to the back of the firewall be sufficient for a Saito .82 or .91? Anyone here have an experience mounting a servo to the back of the firewall?
