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.

Can you get some plastic or rubber tubing and get one end to fit over the brass insert and if that can't trap it in the bore of the tube then maybe suck on the other end of the tube to get the insert up into the tubing. 

A friend bought my old FJ 1200 1986 that I unfortunately dropped in one of the cylinders the little brass insert that was part of the coil wire. ( the part inside the coil wire that attaches to the top of the spark plug. 

We have a bore scope and we can see it -- we also are able to grab it with some flexible wire pinchers but the unable to retrieve it with the pinch grabbers due to the overall width of the grabbers once they hold the brass insert.  So basically can pull it through the hole.

Looking for some other created ideas on how to remove -- without a tear down of course.  Is there anything out there like sticky string that is durable enough not to break as well? 

any other ideas?

thanks for thinking of ideas in advance.

89 tubes and wheels and then early 2000's gold dot front calipers, all of ebay of course, then new brake lines from RPM
