The others in the group know a lot more than I do so take my comments with a grain of salt.

Your 1188 CC kit essentially gets you to a 1986 or later FJ1200 and the jetting you have is in line with that. Since you say the bike runs well I'm tempted to say the PO who installed the 1188 kit took the time to dial it in. You don't NEED to do anything but if you want a bit more from the engine add RPM pod air filters, free flowing exhaust and then the carb jetting changes for those changes will wake it up a bit more and it will sound better.

I strongly suggest the RPM pod air filters instead of the stock airbox. Pick any open (no baffle) exhaust that makes you happy. You can find some used slipons on ebay or buy a new Delvic exhaust. I use the HRS needles and springs in my carbs, links below, I have noticed an improvement in performance with these. The needles and springs must be used in conjunction with each other. The needles and springs are common for the FJ1200 carbs, not sure if your bike has the FJ1100 carbs or the FJ1200 carbs. If you have the FJ110 carbs I'm not sure if these needles and springs would work the same or not. Pilot jet size probably ok, but you may need to add some more fuel with the fuel mixture screws or go to 42 pilot and have less worry about a clogged pilot. With those changes you should bump up the main jet size to 115 or larger but that depends on your area. I'm in NJ and use RPM pod filters, straight through exhaust with short slipon mufflers, 42.5 pilots, HSR needles on 3rd clip from top, HSR Dyna Springs, 120 main jets and bike runs great. I think regionally carb settings are different. I received feedback from our FJ brothers on the wests coast and tried their jetting in my bike but even with the same configuration it just didn't work in my bike, my bike needs the big mains. In talking with some others on the east coast of USA their jetting is more in line with mine so while each engine is different I think the region can matter too.

Looks like it's a 3 cylinder affair and also looks a bit like a Fazer.
I'm with Motofun on this one though there is no beginning for me as i'm well past that stage.

Update #2.  Not as much progress as I would like.

Installed new float needles, needle seats and o-rings in carbs 1-3.  For carb #4, couldn't get float pin out without breaking something, so that carb did not get a new needle and seat. Cleaned rest of carbs and found very little debris or varnish in there.  Floats looked high but left as is.  Put back together and tested on bench to see if carbs would overflow.  Carbs #1 and 2 immediately overflowed.  Took these apart and noticed the floats from the rebuild kit had a different orifice size.  I don't think that's critical but I decided to put the old seats and needles back into carbs 1-3 with new o-rings.  I also adjusted the float level lower on carbs 1-2.  Put back together and bench tested and it did not leak.  Installed carbs on bike with a temporary gas tank.  Started bike up and it ran fine.

I then replaced the engine oil as it has been contaminated with some fuel.  Tested again with a temporary gas tank and carb #3 overflowed immediately.  Seemed to seal itself, so I started up the bike and again it ran fine, and carbs did not overflow.  Ran bike out of fuel and drained carbs as I will be away for a while and bike will sit for several months. 

When I'm back (in the New Year), I'll look into those float levels again and adjust lower as they are still higher than spec.  And I'll find a new float and pin for carb #4 so that I can cut out the one that's stuck in there.  Lastly, the gas tank petcock, that I replaced the diaphragm on, was holding for a while but started leaking again.  I'll need to dig into this one again in the spring.  All in all, quite frustrating.   

I opened up the carbs to deal with a fuel leaking issue (separate post about this) and had a look at what is in there. 

Main jet is 112.5
Pilot jet is 40
Pilot air jet is 155
Needle is 5FZ74 with circlip on 3rd notch (5 notches total)
Fuel air mixture screws 2 turns out
Air box is original, and air filter is OEM as far as I can tell.
Exhausts are OEM.

Again, the FJ has a 1188 cc overbore kit installed.  Not sure if that's reasonable carb set up with that kit, or if anything raises red flags, but that's what I've got.

Passenger seat is too small, otherwise, I'd buy it if Yamaha decided to take notice and make it.

Thank you Pat!  Really have appreciated being able to list the bikes on the forum.  May hang out for awhile.  Keep the rubber side down 

Excellent! I'll revise the post title as ***SOLD***
