new FJ owner carb questions

[holes41]

 

Out of curiosity, what are all the hoses and T fittings for coming off the front of the gas tank for? It is a california model if that makes a difference.

That sounds like what I saw on CA FJ's. It is a vapor control system that uses two charcoal canisters, check valves, bunch of hoses and a solenoid. It controls what direction the vapors go depending on if the engine was running or not.

I replaced a t fitting there that had broke, I was considering going throught those fittings and hoses but being that they are just vapor recovery they won't affect the way it runs , is this correct ?

UPDATE.. parts arrived but everyone make sure you closely inspect your parts, 2 of the carb rebuild kits contained #52.5 pilot jets instead of #42.5, so I went ahead and just ordered 4 #40 pilots. Bike should be done in a few days . I can imagine scratching my temple on that situation if it went undiscovered!

Good catch on the jets.  Shows you are paying attention.  Whats the saying, "trust but verify"...

I found another small issue. The internal washer for the oil filter is missing, Yamaha calls it a "washer plate", does anyone know if there is a washer out there that I can find besides from the factory?

I don't know what the dealer wants to charge you, but the washer can be had for $2.00 here. http://www.partzilla.com/parts/search/Yamaha/Motorcycle/1989/FJ1200W/OIL+FILTER/parts.html

Thanks Fred, Its 3.76 at the dealer I just didn't want to wait another 3 days ,  no luck in my drawer of washers but I will check another local source tomorrow before I order it.

Did you get those kits from me? If so can you please send the incorrect jets back to me and I will send you out the correct ones. I will credit you for the shipping cost back to me, but I need them to show the manufacture the issue so it does not happen again.

Also, if you change over to the spin on oil filter adapter, you never have to deal with the washer or spring again.

Randy I am not sure where my mechanic ordered the kits but if it was from you I can send the 52.5s back if it helps prevent this in the future. Im not worried about shipping costs . we already got 4 #40 pilots and they were shipped super fast so they may be from you, my mechanic is in Hanford and I'm in Fresno. I will be ordering the adapter soon when budget allows as well as your oil cooler kit. You know how these central valley summers are.

Guys I need some help regarding my carbs, the mechanic put everything back together and set the floats to 22.3mm using a float gauge and measured them from the curved edge of the float, he set the screws at 2.5 turns and says the bike runs excellent and rides excellent, jetting seems to be spot on and no leaks,,, until after a 20 mile ride he shuts off the engine, puts the bike on the center stand and there is a drip from 2 of the carbs coming from what Yamaha calls "choke vents" not the overflow. im about at my wits end here, any ideas ? every part in the carbs is new except the diaphragms and floats PLEASE help before I take a sledge hammer to this thing

[movenon]

I am sure others will be here shortly to help out.  Sounds  like he measured at the correct point but did he do it with the carbs at somewhere between 90 and 70 degrees tilt ?  If he did it with the carbs upside down the they are probably out of adjustment.  Voice of experience...
Other than that the usual check, clean the needle and seats and new o rings, sticking floats... Hopefully just an adjustment.  If two of them are leaking I would look at the float adjustment.

Have faith when it is running correctly it will be fine.

Thanks George, he also said it seemed like there was pressure but I didn't understand what he meant. Could it be something with the Ca emissions equipment?

[movenon]

Pressure ?  Perhaps fuel pressure from the fuel pump ?  What is he going to do about it ?

I told him there was talk on here of the fuel cap issues and he said that was one of the 1st things he did was the flapectomy, he wants to check all my smog stuff and if he has to hes going to pull the carbs again and redo the float adjustment, I am not sure if he did it upside down or not. He currently builds alcohol motors and other race related builds but he began his career as either a Honda or Yamaha factory technician in the 80s, his reputation here is well known in the amateur racing circuit, I didn't want the shadetree tweaker touching my bike lol. I have faith he will nail it, it just hasn't gone smooth like id hoped. For the generous discount he is giving me I hate to see him put another 4 hrs into this but it may just have to be. The good news is its runs perfect , just drips from choke vents on 2 carbs. I wouldn't think new needles/seats and orings would be sticking especially on multiple carbs
Wouldn't too high of a float adjustment cause a drip from the overflow tubes instead of the choke vents ?

I talked to the tech this morning and we covered everything that he needs to check & resolve. I think once he checks & adjusts a few things you will be ready to go.
