Cleaning carbs. What should I replace?

[dimlocator]

1982 GS850g 24k mi. Carbs are all plugged up and I'm just starting to take them apart for a good cleaning. I only want to do this once, so while they are apart what should I be replacing?

Thanks

Hey....I know where you live....well, not exactly where.

Do this. Step by step...it's a great tutorial. Check Cliff's site too, it's chock full of 850 lovin'.

Make sure you strip the carbs completely (ie every component separate) and clean everything twice. You guys can get a good carb dip so a 24 hour soak should do the trick.

Plus it's well worth replacing all the rubber O rings: http://www.cycleorings.com/

And check your float needles to make sure that they aren't worn (magnifying glass helps). If in doubt replace.

Check the diaphragms for pinholes. Hold them up to the light and if you can see any tiny holes replace them.

I forgot.....be VERY careful removing the pins that hold the floats. The posts that hold the pins are subject to snapping off when your trying to get the pins out. If you can get enough of pin started, grab it with a pair of needle nose pliers and gently twist it out.

X2, just did this and it worked great, follow cliffs page and replace o-ring set.

Use good fitting screw drivers!!!!!

Just to add-- IT is mandatory!!! to replace ALL the O rings..

I second this! Dont get in a rush and try to remove things with the wrong screw driver, it does not end well.

Also if you can't get any jet or whatever out, soak it in carb cleaner and try again tomorrow... Don't rush when you are doing this.

Protect the carb float posts while driving out the pins.

Get some JIS screwdrivers. Great investment.

Shim the carb needles while the carbs are apart (assuming your bike has stock intake and exhaust). Shave down the orange plug 1 mm using sand paper. This improves cold start performance and reduced surging and improves driveability.

+1 on protecting the posts - they do break easily if you aren't paying attention or you are having problems removing the float pin parts. CdNoel put a post in Tips and Tricks on how to fix them if you need to - http://www.thegsresources.com/_forum/showthread.php?t=159769&highlight=broken+posts
