Can you rotate it so the piston is top dead and the valves are closed and try and suck it out with a powerful vacuum cleaner.

You could try taping a larger mcdonalds size plastic straw to the hose of your shop vac and insert it through the sparkplug hole.
 I don't know whether those are still legal and available in California .

Did you sell it yet?

It's actually about twice as tall as a main jet. So I don't think there's a snowballs chance it comes out of the either intake or exhaust valve.

Make sure you have all the pieces when you put it back together as well.

Some will remember my 90 from the WCR -- and briefly my 86 too.  Well -- things happened and both fell into disarray for lack of a better word.  The 90 was laid down and the 86 -- well I dropped the brass insert into #2. ( see running problem post).  The good news is the new owner " Gratis " was able to perform what I was thinking of doing which was make one bike whole -- Move the body work on the 86 over to the 90 - It wasn't a clean swap as the mounting was different but he got it done and now he has a clean running machine that IMO has the best looking body of all the FJ's.  Once the tank is painted he'll be done.  Well done Dan.

Maybe also put a shop vac on the exhaust port to add some suction while pushing in compressed air into the spark plug hole?

Exactly. Intake or exhaust port are bigger so easier to blow it out.

Since winter time is best time to collect parts, just picked up another set of 96 YZF 750R SP forks....

Will need to compare both stems to see how much work is required to fit it in.

I think the brass insert is too large for it to come out of the valve. If I recall they are about the size of a main jet and unless you got some monster cams in there I don't believe they would have enough lift to get it to open far enough.

Maybe try some 3m double sided tape on a semi flexible rod to get down in there and just stick it on there.
