RE: Welcome to Club SAITO !
Bill,
Before I soak it, I'll pull the plug and see how free it spins. I should have done that last night.
After I soak it, I'll let you know what happens.
Also hobbsy,
Any suggestion on what to put in the YS? I would hate to fire it up and have yet another problem. Does the petroleum hurt the diaphragm or what?

Silicone rubber is destroyed by petroleum aromatics. The YS regulator diaphragm is silicone rubber. You should also avoid acetone and toluene solvents. I think Xylene and xylol are OK, they're vegetable based. Plain old amyl acetate (banana oil) should be ok too.

#60 here,
I have my Saito82 mounted side winder in an acrowot, the exhust looks very vulnerable to catching the ground if I nose over, could be a very costly repair. Does anyone do a shorter header pipe?
By the way this engine is great, still running rich as it sucked a 14oz tank dry in just under 10 mins, and when I say dry I mean every last drop. Not many engines can do that!

Yes, the exhaust is hanging in the breeze, but it's a lot stronger than you may think.
If you are really worried about it, get this:
Muffler, Rt Angle Adapter: FA65-1 [SAI65140]
List: $14.99 Our Price: $14.24
frrom Horizon.
If you go [link=http://www.rcuniverse.com/forum/m_3371686/tm.htm]here[/link] I've listed two rigid and two flex pipes that will fit the FA-100, all being 12mm threaded exhaust parts.
Bill.
PS: Performance Specialties also has parts to fit Saito, most are priced about four times the cost of the similar part from Horizon. wr.

Bill,
I stopped by the autoparts store and could not find the Air Tool oil blend of Marvel Mystery Oil, but I did get the regular blend, with that wonderfull mint aroma. That night I pulled the cowl off, pull the plug and also noticed that I had left the crankcase vent tube plugged the last time I did maintenance to change out the muffler. Hum, maybe this had caused my crank case to run lean or make the trashing noise.
Anyway I socked a good bit of MMO to the crankcase, spun the crank and soaked it again, let it set for 48 hours.
Then I fire it up last night, and run a full tank through the Satio 91 with no clicking, cracking screetching or other noise. I'll put the cowl back on and try it again at the field this weekend. Cross my fingers.

With no vent the crank case pressure will rise to the point that there is no amount of oil getting past the ring. In other words, yes, the plugged vent could have given you a problem.

Cheers William, gjeffers,
I was a bit worried that it would damage the head/barrel. I may take gjeffers sugestion and cut the pipe down a bit. If I wanted to extend the thread a bit do u think just running a 12mm die down the pipe would work?

[b]Airbus:
Sorry, I (and I suppose Gary) assumed you had the later exhaust, the straight pipe that is threaded full length. Talking about extending the thread, yours must be the curved pipe.
So long as you have a really food quality 12 mm die with a 1.0 mm pitch you should be able to cut more threads on it, but be careful and use a good cutting oil. The pipes are very hard, a "Harbor Freight" die will probably break before it cuts anything.
You might do better getting the SAI8075B straight 12 mm pipe for $9.75, it's long enough that if you cut it in half both pieces will be long enough to mount the muffler. If yours is the cast muffler you can still rotate it out of the way.

William,gjeffers,
sorry for not explaining myself properly [sm=rolleyes.gif].It is the curved pipe and what looks like a 2 piece cast muffeler.
Thanks again for the advice,
Leigh.

Hi all,
I just acquired a Saito 90T Mark II. It's sufficiently different from the 90TS that the TS manual isn't of great help. Does anyone have a 90T manual they'd be willing to photocopy for me (I'd reimburse and pay shipping)?

Guys,
Please check out my listing titled "Saito 65 Bent Crankshaft?" I have a Saito 100 and the 65 GK.
The 100 runs great, the 65 used to...now it just looks pretty. Any help would be appreciated...I don't have much time before the weather closes in here in Ohio.

Nothing comes up for me in that search. Can you give a link?
Regarding the crank, I've straightened many Saito crank shafts. PM or email for details.

If you measure the outside diameter of the intake pipes, I think youl'll find the older one is larger. Saito decreased the size to keep the air flow higher, giving more consistent running. They did not alter the cylinder to match the smaller size, that's where our current vibration and intake leaks have come from. At least that's my opinion.
First ran into this with an FA-80. Had a dent in the intake pipe, ordered a new one. When it got here it rattled around loosely in the head. I reused the old one, the new one is in my parts bin.
If you do find your pipes are different, you can order the later replaement.
While the difference in the muffler is there, I don't think it will make any real difference.

Well I emailed Horizon hoby on Friday to see if they would send out a straight header pipe to me in the UK, still waiting on a reply [] .

RE: Welcome to Club SAITO !
Well count me in here somewhere. I have a new Saito 82 that I haven't even fired up yet. Should I put some silicone rubber on the intake manifold o-ring while everything is still new and clean???
Thanks,
Ernie

Hold the cylinder in one hand, with the other pull on the intake pipe. If you can move the pipe with moderate pressure seal it, and order a new backplate. Do the order by phone, talk to Dennis Davenport. Explain the problem, he'll take care of you. If it's nicely rigid you can put some RTV in as insurance, but you'll probably be OK without it.
