LAST EDITED ON Sep-28-04 AT 03:48 PM (CDT) Finally test flew the Tony this past week.Have about 5 flights on it.
Had to shim the tank down to get lap times the same. The 72 saito just doesn`t have the power needed for this altitude. I put a bigger venturi in it but still not enough. Should have the 82 back next week which I`m having balanced.Tony seems to be flying the same as before which is a good thing.I`ll let you all know how the 82 works when it comes back.

Saito 82 balanced? How are going to balance an 82. And if that is so, The .91 would certainly get the nod if you can do the same thing. This sounds like a major development!!
Milton,
You cut accouple of grams of the inside of the piston. And add some tungstun metal to the crankshaft. Greg in Denver colo.is doing the work on it.Hope to hear back from him soon for the report.

Not surprising to me the Saito 82 has zero additional counterweight as compared to the Saito 72. This could explain why it is such a shaker.

Is it possible to ask this Greg about the Saito .91. Many years ago, I rejected the Saito 91 in favor of the Saito 80 (The Saito 72 had not come out yet) because of what I felt was too strong a tendency to "Rhumba." In light of the FAI 15cc ruling, maybe this Greg can help me develope a serious a#$ kinking motor if he can work his same magic with the 91. Now, it is important to remember, the Saito 91 DOES NOT have a problem of EXCESSIVE vibration, it just has more of it than a Saito 72. In fact, the Saito 91 is considered one of the smoothest 91 4 strokes out there. But, if it can be made smoother still, then I feel I may have the makings of one the deadliest stunt motors ever developed.
