carb questions - carb boot torque

[tab1324]

I am in the process of doing the 'triple clean' of the carbs and let me tell those who don't believe in doing it 3 times - it's worth it. The bike was backfiring when starting and would keep running. Lots of advice from this forum told me to check the pilot jets... One of them was plugged. Also found a very small hole in one of the carb diaphragms I hadn't noticed before - plastidip will be used to repair it.

The carb boots will also get plastidip treatment. When removing and re-installing them, is there a tourque requirement? I don't have a manual yet, but am finding I really need one. It's an 82 XJ1100.

Also - What is controlled by the small screw on the top of the carbs? The idle adjustment is the butterfly adjustment right??? Is the small screw a high speed adjust or something?

Thanks,

Tom B.

I don't believe there is a torque value specified for the carb boots, but if there was, it won't be too high.

As for the screws in the top of the carbs, they adjust the air/fuel mixture at idle. When removing these, VERY gently seat them all the way in first, while counting the turns. This will give you a base starting point when you put them back in. Be very careful not to overtighten as the tips can break off. See Broken tip removal. Turning in leans the mixture, out richens it. To set these properly, a lot of people use a colortune. Colortune

Hey there Tom,

I read your other posts in the other threads, and Brian was correct. You found your pilot jets clogged, and now you have found your Pilot Screws, which are another part of the IDLE circuit and adjustment. With the butterflies all the way closed, the bike should idle when these pilot screws are adjusted properly. Usually about 1&1/4 turns out from gentle seat!! You'll want to remove them, watch out for the little parts, rubber and metal washers and springs, and do a good spray cleaning thru the pilot jet circuit!!!

Then, like Ken said, make sure your grips are on tight, cause you're going to need them!!! And keep your right foot ready on the rear brake so when the front wheel comes off the ground, you'll be able to bring it back down.....the front brake won't work when it's not touching the ground!

guess it's a quick bike huh? I keep hearing that... Hopefully by the weekend I'll be feeling it.

Tonight I put the carbs back together, giving them AGAIN a thourough cleaning, paying special attention to the idle circuit. You say I should get the butterflys all the way closed and then back out the idle adjustment about 1 1/4 turns? Is that a good starting point or shouldn't I have the butterflys open slightly?
