An even cheaper version is from Harbor Freight, probably came out of the same factory in China. With a 20% coupon, they're practically be giving these away. https://www.harborfreight.com/hardwa...ent-67554.html
Sounds cheap until you're out on the road with a fuel leak.
I have all these Chinese O Ring kits. There's usually something in there close but seldom exactly right.
Y'all use this stuff in your bikes if you want but there's no way it's going in one of mine.

Instructions

Has anyone used this web page for separating the carbs?

http://www.angelfire.com/ia/z/FZ1carbremoval.htm

About 2/3s down the page, the Separating the Carburetors (Reverse the procedure for installation) instructions start.

Thanks,
Eric

Looks reasonable, but I'd only remove/rebuild one at a time. Start on the one side and work your way to the other

Chuck:

Sounds like a great idea. Do you know where I can find the size of the O-Rings? I spent the extra bucks and ordered them from Yamaha, but I think that I would like to make sure the correct size is in the Northern Tools kit.

Thanks,
Eric

I just used the ones that fit.

I do not. I happened upon mine through a friend aircraft mechanic, so I've used it sparingly. When I need more I'll order it online as well, with shipping almost doubling the cost. Oh well, it is the cat's meow (for specific applications like this). Do it once, do it right.

FWIW, I've always just used Vaseline for any fuel or ATF O-rings, fuel injectors, carb parts, trans lines. You're just looking for something to lube it so it doesn't shred when you install it. Honestly spitting on it is probably enough.

Spitting....that sounds like fun.

I have some Liquid Wrench Silicone Spray in the shop. That should work ok.

I deal with o-rings just about daily on life preserving equipment, so I tend to go overboard in some cases. I'm just used to making sure components function to their highest reliability. At the very least, use a lubricant when installing, as Parker will tell you, that is by far the time when o-ring damage will occur.

It would suck having to tear a carb bank out and apart just for nicked o-ring. I should say, does suck. Been there, done that.

Personally, I don't like silicone on silicone o-rings because it makes them swell. That's not intended in the design. I do like the EZ Turn, as it will stay with the o-ring a very long time, not evaporating or washing away. Slippery o-rings are good o-rings.

I wouldn't want to lubricate the O rings with something that might break down the questionable composition of that Chinese rubber, over time.
I have rebuilt the carbs on both my bikes. The 05 was done in 2017 and the 04 was done in 2018.
Neither had given the slightest problem nor had either been apart before, so I figured it was time to have a look inside them.
Everything I removed looked as good as what I put back, still haven't had a problem and intend to keep it that way.
I see no reason the OEM parts I used won't last as long as what was installed at the Mikuni factory if I am able to assemble these carbs with equal care and precision.
A tube of genuine O ring lubricant won't break most of us up so it worth taking a chance to save a dollar or two?
Not to me.

Chuck:

Interesting article on Silicone Lubricant https://pressurewashr.com/silicone-l...ubber-o-rings/.

Looks like the grease or paste works better than the spray, due to the additives to make a spray, a spray.

This looks like a winner https://www.super-lube.com/o-ring-silicone-grease

So does this one, but it is more expensive https://www.amazon.com/Dow-Corning-V.../dp/B001UHMNW0

Thanks again for the comments,
Eric

Seems like it should work, however I'm surprised that silicone is recommended for natural rubber. Back in the old days I had some natural rubber brake lines in a British car and the previous owner had used silicone fluid which basically destroyed every rubber bit in the brake system.

This is all new to me, I've rebuilt countless automatic and manual transmissions, engines and other mechanical things with O-rings and until this thread I had never heard of "o-ring" lubricant, nor ever seen it referenced in a service manual.

Chuck,

O-rings are fantastic and highly capable components, but only if the engineering behind it is sound. In most applications, as long as you use the components that were properly engineered for the application, all is good with not much to worry about.

However, questionable materials (China Freight parts), practices, and operating beyond design tolerances, may end with less than desirable consequences. Think back to January 1986. Not a fault of the o-ring, but operating outside design parameters.

https://en.wikipedia.org/wiki/Space_...enger_disaster

I had 247,000 (hard) miles on my first RX7 with the rotary engine, a 1980 model. Those o-ring side seals were fantastic.

Also, I tend to stay away from silicone lubes, as silicone has a fantastic way of migrating everywhere, and possibly in places it isn't desirable. At an aerospace company I used to work for, we actually shut down our space lab for two weeks for cleaning due to silicone contamination. The stuff can be a double edged sword.

I just struggled with this springs. I did not know anything about them but i was able to get it back. Fine, small pliars and some luck is needed.

I was trying it one day and got frustrated, then tried it the second day and the spring went back at its place very easy...i swear i did nothing different

Chuck:

Ok, that makes me feel better. Maybe the lubricant is for newbies that can't get the o-ring in without "nicking" it. Experienced people are better at getting the o-rings in correctly (they have had lots of practice). I am more used to getting wood joints to come together properly, than putting in o-rings.

Ok, I am definitely listening....I will try to not make a mess and only keep the lube on the o-ring. Another reason not to use a silicone spray....

Good advice...When frustrated, walk away and come back the next day...I can do that. I do it every time I measure twice and still end up cutting three times...
