Last week, I ordered an airbox off of ebay and finally received it, only to find out that the right side cover was missing.  My fault for not seeing that when I bought it I guess.  So back to ebay - The same seller was selling the cover separately!  Had to buy that, too  :'(  The next steps to getting this bike to start would be to check the valve clearances, plug in some electrical connections, install the carbs and try to start it.  Easy Peasy! I'm sure it'll start right up  ::)  I do have a 4 into 1 exhaust manifold that came with the bike.  I think I'll put that on just for start up.  I'll have to get something else in the future.  The thing is pretty ratty!  And I soaked the chain for 3 days in motor oil and hung it at work.  Looks to be in 'ok' shape.  Nothing I would want to ride cross country, but it'll work to test for the dreaded 2nd gear issue on these things.

So who is the resident FJ 1100 expert around here?  Question:  There is the big fuel line (2 into 1) coming from the carbs that goes to the petcock and there are 4 overflow lines coming from the carb bowls. These I understand.  Then there is a tube coming from the petcock that I would imagine goes to the engine somewhere (vacuum)? I'm not sure where it hooks up on the engine?  And also, there are two more medium sized tubes coming from the carbs that I have no idea where go.   If it makes sense, great.  If not, I can provide a picture at a later time.  Thanks in advance.

The vacuum hose goes off #2 intake rubber, IIRC.


The two "other" hoses will be breathers hoses for the carb bowls. Or if the bike is a California model, they might have gone to carbon canisters. Either way, just route some tubing either down in front of the swing arm or up under the seat - don't plug them up.

Thanks for the info.  I see the spot where it hooks up, but there is a small boot covering the port. On the 3 and 4 carb ports,there is a small tube thats there that connects the two.  It appears they have been there for awhile.  Hmm??  When you say carb number 2, I am taking it as the second carb from the right. 3 and 4 are the two on the left.

cyl # 1 is on the far left when you are sitting on the bike.


It doesn't matter where you plug in the hose for the vacuum tap - any of the ports will work.


From memory, I think the earlier FJ's had a vacuum advance (the hose that's on #2 in your pic). Where does that hose go to?

It goes to the number 1 carb.

OK - have you got the ignitor? From memory that hose went there on the first models. If it doesn't on your ignitor then you can route that hose from #2 to the fuel tap and cap off the port on #1.

I'm going to say that it does, because you mention early bikes, and this bike has an 1983 VIN Tag on it.  I remember on the igniter there is a small looking tube or handle that comes off of it.  I didn't know what it was for.  I'll look at that when I get home and see if it's an actual tube.
