Pre-Season Carb Cleaning

[movenon]

Good on the carbs.  First challenge is the broken screw.  Take some pictures when you get them.  Can't comment on the screw removal until we can see it.
If all else fails you can use your carb body. IMO that looked like a pretty good deal considering the price increases that we are probably going to see on the carb related items.  Worth it just for the sides and diaphragms.

Received the carbs yesterday! Began looking over them this morning at work. Diaphragms are all good! Has all stock jetting and the guy pretty much mutilated the needle seats getting them out ... but they are out. As for the stripped screw, have a picture.



I tried individually pricing the things I needed for these carbs ... completely surpassed the price of just buying 4 rebuild kits haha! So, 4 rebuild kits will be ordered along with #40 idle jets and the SS screw kit. After all of that arrives, it's just a matter of throwing everything together and dialing it in!

My first thought is to leave the screw in,  don't take the butterflies out.  I see no need to disassemble it that far...?   Buying a complete kit is the way to go, all new jets, emulsion tubes, needles (adjustable), fuel air screws, needle and seats, O rings etc..  IMO RPM is the best place to get all of that.

IF you decide to take that screw out. soak it with a mixture of acetone and  ATF fluid and try to find a small JIS screw driver or modify a small Phillips head driver.  Be careful not to bend the shaft or beat the shaft bearing in the body.  I would leave it alone if possable.

Make sure you get the gravity feed needle and seats if that's what you have.  88 and up are fuel pump seats and are smaller.  Study the fuel inlet hose system, you will have to probably have to use your "Tee's" or order the parts to make that work.  Take pictures before you tear yours apart if possable.

Or just replace the one body that is bad on your bank ?  What direction are you going to take ?

It helps to dress some screw drivers down so the fit nice and snug in the straight slots of the jets etc.. helps from tearing them up.  Inexpensive drivers work well for that.  Just a tip.

Along with George's recomendation for complete repair kits from RPM, I would also recommend getting this kit as well:

http://www.rpmracingca.com/proddetail.asp?prod=carbkit&cat=24

It basically replaces all the  phillips head screws with SS allen head bolts and includes additional O-rings that aren't in the other kits.  If you ever have to disassemble your carbs again, you will defintiely appreciate the allen heads.

+1 on that

Just was looking at your picture. I was assuming the existing screw is the problem but perhaps its the empty hole that is the problem.... Let us know...

If it's the empty hole that is stripped find out the size of that screw... If its the empty screw hole, try to fine the screw if he sent it. Check the threads on it.  Either the threads stripped on the screw or the shaft, or both are buggered ?  First try would be to install a new screw (ACE hardware).. Might not hurt to run a same size tap in it.

More info ?

I remember trying to remove those screws once and they really didn't want to come out.  I recall getting about a 1/8th turn and then the screw getting tighter.  I came to the conclusion that it was peened on the thread side (like a chain rivet link) so it wouldn't accidently fall out, which would be a very bad thing given its location.

If you replace it with a "regular" screw make very certain it's in there to stay.  If it was me I might consider something like a pop rivet (but I would want it to be as flush as possible.

The missing screw hole does have a screw and it does thread in all of the way. He removed all of the other butterfly's except for that one. After checking the overflow holes and main fuel feed inlet of the offending carb, I can use one of my carb bodies.

The SS screw replacement kit was the first thing on my list even before I removed the carbs from the bike ... the second thing quickly became the pods while I was removing the airbox haha

I plan on using everything that I don't get in the RPM rebuild kits for the new carbs from my old carbs (diaphragms, fuel/overflow fittings, etc.) and I'll be ordering everything for my model year. All of my fuel T's are in good shape, except for the o-rings. I also removed the needle seats from my original carbs and they are now unusable. I noticed the needle seats were different and even the idle jets look different than my gravity carbs. That being said, if anyone (or you know of someone) that needs some random parts, I have some.

Once I deposit some money I made over the week doing side work, my rebuild kits, pods and PCV filter will be ordered. As far as I can tell, that's all I'm going to need. Thank you guys so much. After this carb work is done, I'm moving on to my chain, sprockets and a front tire! Then it'll be time to ride again.

Sounds like you have a plan.  There are 2 styles of pilot jets.  Use the ones that come with the rebuild kit. Should be picture of the jets here.

Advice: change out the large O rings that go between the intake manifolds and the head.
