Ive broken-in and tuned 2 saito engines using the method described in the link below(91 & 100). FLAWLESS ( for me anyway). I have yet to have my first Saito quit(91)...and the other I just broke in a few weeks ago and have yet to mount, but the idle is just perfect and smooth with great transition. Take a look at the site. Alot of great info on Saitos in one place.

Upon initial break in , obivously the needles are sloppy rich. One tank lasted about 5 minutes on the Saito 100. After tuning and running on bench at all rpm levels, I got a solid 25 minutes out of a 10 or 12 ounce tank( dont remember which). I sure Ill get a bit less in flight; but expecting at least 15 minutes if not more.

Take your time and become a perfectionist at tuning. You're planes will live longer - my way of thinking anyway.
