Thanks, will hold off on buying something overseas with the tariffs and crap that's going on for the time being. I don't see why a long thin fabric or old sheet oiled real well and pulled through then stuffed back in really tight won't accomplish the same thing. My wife won't be happy but there is an old sheet that she won't know is missing, lol.

or just a long rubber tube like fuel line with a wire leader.

Howdy Bonz,,,,,I wouldnt recommend putting any cloth in the passage to block off, as it is a high vacuum inlet port all the way through the carb air inlet ports,,,,,if anything gets sucked in it could be a pain in the assss to remedy. The bike will run much smoother with a sync done with the YICS tool, or the YiCS eliminator but will run decent without the tool, provided the carbs are setup correct. Maybe a gas line the just barely slides like DEEBS suggested, not sure if that will block off the complete air inlet along with the carb air inlet....just recommend the YICS tooll for best results, after my long term 40 plus years of having an XJ1100,,,,maxims rock, just harder to get certain parts as it was a one off of the xs1100.....Mike in San DIego and Pa......

Thanks Mike, good food for thought. The reading I've done suggests pulling the long, narrow width cloth through (wet well with atf or oil) and stuffing it back in so it's packed tight the full length of the passage. The tightness of the cloth not just the diameter of the passage, but the length of the passage, seems to keep it from getting pulled in. If it was too loose it definitely wouldn't be good. Once I see how it's running on the street I'll decide yay or nay on the tool.

I haven't read any bad stories about making it worse by sync'ing w/o the tool, just that it won't be as good as with the tool. Is that pretty much the case?

[Socer4m]

HI Bonz,,,,way back on the site there was a picture that detailed the passages for the YICS,,,only three spots need to be closed off,,check out the rubber on the YICS TOOL,,by closing off the rest of the inlet could keep it from synching correctly by varying the inlet air,,,,,so,,,would recommend the tool,,,,but without out it it will run at 90-95 percent if all else is good. If you are keeping the bike I would suggest getting a YICS TOOL, as it is good to synch pretty regularly to keep the xj in peak performance, Mike in S.DIego and PA

[Bonz]

Understood on the 3 spots. Thought... If they are blocked individually by the tool, the rest of it is dead air space around the small margin left by the diameter of the tool and would not affect anything, IMO. If it's blocked fully by any means, it would seem to my thinking to be no different with respect to the sync than blocking them with the tool or not having the passageway in the first place, a la the XS1100. Just thinking out loud.

You know, a gun cleaning brush works excellent for cleaning that tunnel out. There are only four holes in that tunnel that need to be blocked. I don't think anything can get caught on them. I wouldn't be afraid to attempt the oily rag and ramrod method.
Some of these XJ's have the plug on both sides, that may make it easier. I have read of people doing it like this with success.
