Blasphemy!!!

The only issue here is "if you don't have the tools". I happen to have the tools and don't need to go to the dealer, then again... my bike runs. Better to spend the $50 than to clean your carbs 3 times and still not get all the crap out of them. The tools to clean the jets are cheap, but never in stock. Since it's going to be in the 50's Saturday I'd say it's worth the $50 to ride all day. BTW of all the carbs I've cleaned they all ran after, better than anyone remembered them running and I never had to buy a single part. You can have these back in and running cheap, and ride Saturday. Spraying them with carb cleaner isn't the right way to do it. Take the time to clean them right, or have them cleaned right, it will be worth it.

Man, I can't believe how hard some of you are making this. You don't need special tools to clean jets. All you need is some copper speaker wire. Take a short length, strip it, and use the strands to clean the jets. Copper is much softer than brass, and WILL NOT damage the jet. If the strand you are using is too small, double it up. If it is too big, Duh, get a smaller gage of wire. The mains usually don't clog,, TOO big. The pilots,,YES!!

screw it, the bike is junk ......i'1I give you $500 for it

bbhzx11- what are these tools you speak of ? link ?

[richw]

You are totqally wasting your time if you aren't looking inside the float bowls. There are probably dead minnows in there

I asked them how much it would be to pull the carbs apart, clean them and re-assemble. They guaranteed me it would be at least 2 hours, at $65/hr for labor. Not to mention parts cost.

I've actually got a neat little tool thats used for cleaning pilot orifices in gas appliances, it goes from hair thin to about the diameter of a small needle, would that do the trick? The name of it escapes me right now.

[richw]

I have never used anything but hand tools and
spray carburetor cleaner.

For 10 year olds you may need an impact screw driver that you
should be able to get for under $10. Do not mangle the little phillips screws on the float bowls


Do one at a time on a clean bench with a clean floor with a couple of containers to store screws etc without losing them.

The pilot jet is usually located nearest the engine side and all I have seen just unscrew and you can take them out and squirt from the inside.

Don't manhandle the floats and you should be fine.


Then advertise basket case

Should be the right type of tool

[Hardcore]

just use a 1/8 inch drill bit with some wd-40 !
drill out all jets + orifices but spray with wd-40 while doing it--NEVER EVER drill them out dry !!!!!! bike will be killer fast when done!!

+ test the bike with carbs OFF !! crank the bike over while spraying carb clean into the open intake ports--DON'T TOUCH THE THROTTLE while doing this--this should clean out your combustion chamber--don't be afraid to use excessive amounts of carb cleaner--the more, the cleaner it'll get !!!!

[richw]

put a monkey paw in a paperbag swing it over your head while reciting the jaberwaki

[Tabby]

RICHW's other post is right. Those screws could be a pain. If you intend to keep the bike long term, now would be a good time to switch all of the phillips heads that you would normally remove for servicing, to socket head cap screws. Makes things much nicer down the road. I do that to all my carbs. Your tool is indeed a jet cleaning tool. If it is made of steel, and I'm pretty sure it is, don't be overzealous with it. Like my earlier post, the brass jets are softer than steel, so you CAN damage the jet.

[Tabby]

Oh yeah! Hardcore, you are a trouble maker!! Do you want him to fill his pants?

[richw]

Sounds like your chicken....or wize

why not ask for someone to help with you driving to their house ?

[Tabby]

??? I'm thick headed. Was that directed at me?

If anyones offering, I'd be more than happy to on Saturday.

Yamaha carb cleaner can be used "in situ" with a mixture of gasoline. They say to do this as the carbs are still on the bike, but you could do it even easier as they are now off of the bike. Just do it OUTSIDE. Disclaimer: i bought some and have yet to try it but I hope to do the same thing this weekend.

no really, it'll work awesome!! he's gotta try it---plus the bike will rev up SOOOOOOOOO much faster!!!!!!!!!!!!!!

[Tabby]

Heart rate, and blood pressure on himself also. Do they make rev-limiters for your ticker?

it's very refreshing to give your heart a natural jolt of adrenaline!!

[stoinkythepig]

This is what I did when I was in a similar situation. Very lazy of me, considering the amount of tools I own and the fact that I know how to reguild carbs and stuff but it worked

[Tabby]

Thanks Stoinky. I myself don't have a problem right now. I have been a regular user of the Chevron "Techron" fuel additive. Nice to know, just in case.

good plan!
As long as you dont plan on stoppping the thing when you get somewhere cause the plugs will be all fouled up and you wont get a second start out of 'em!!!

Oh well, I got into them today and cleaned everything up. Just waiting on a new set of gaskets for the float bowl covers as they werent salvageable.

Jets were surprisingly clean, so who knows. Diaphraghms were all in really good shape, pulled those out and cleaned off the slides and the pins, as well as removed all the jets and jet holders and blew through all passages with a can of carb cleaner. The holders and jets are still sitting in a can with some cleaner, will reassemble once I get the new gaskets early next week. There was a very light coating of varnish on the very bottoms of the bowls, but everything else was in really good shape. Even the strainer screens on the floats were spotless clean.

If it doesnt run next week, who knows.......

My petcock has always been very slightly leaky, so I ordered a new o-ring for that, so I'm gonna empty the tank out to fix that, and put some fresh gas in while I'm at it.

The carbs looked like a PITA on paper, but when it came down to it, it was alot easier than I thought. All I needed was:

Impact Driver
Phillips Head
Flat head
6mm socket



Now if only I could get the smell of carb cleaner out of my fingers.....

are you soft or sumthin? just use a 1/2 tube of rtv black !!

[Tabby]

Pretty cool Eh? Now you know what's in them. It only gets better. Unless you wimp out and get another bike with FI. Real mens' hands smell like carb cleaner. Not those wimpy guys going tappity tappity on their laptops adjusting their fuel maps. {if Suzuki ever puts FI on the Bandit motor, I'll be sniffing around the salvage yards for the first wreck!!}
