How to Clean a Carburetor





Introduction: How to Clean a Carburetor

Spring Cleaning Contest

Cleaning a carburetor can greatly improve engine performance and, often times, solve other fuel/air related problems. If a bike sits for any certain period of time without having the fuel drained, the carburetor could suffer damage and thus cause poor fuel economy or even keep the bike from running at all.

If you're bike is carburated and sat over this past winter, out in the elements, or even in the garage, it may need a good carb cleaning!

This instructable will walk you through removing, disassembling, cleaning, reassembling, and reinstalling a carburetor for a 1995 Suzuki LS 650 (Savage).

I bought this bike back in March 2011 and I thought I would record all the modifications, etc. that I do to it before I'm finished turning it into a sweet lil'bobber.

Tools you'll need:
Small flat head screwdrivers (several sizes)
Philips head screwdriver
Pick Tool
Needle Nose Pliers
Shop Towels
Carb Cleaner

I entered the steps in the diagram boxes within my pics.

Remember that ORGANIZATION is a must when removing parts from a bike. Using lidded containers will help ensure that parts don't go missing because of accidents. There have been so many times I have bumped a container and had it fall from my table or work bench. I learned after the first time, keeping parts in a lidded container will keep those parts from spreading out all over the shop!

To reassemble the parts, follow the steps in reverse order.

Hope this helps!

    Will this work with a suzuki boulevard S40 carb?

    how did you shut off fuel? mine days RES, ON, or PRI.

    Hello, very good 'ible!
    You have no idea how much I like your bike! I have been looking for on like yours but here in Seattle are hard to find, I guess. I have a 1975 Honda "Naked" Goldwing GL1000, a 1971 Honda CB500, and a 1976 Yamaha XS650 "Digger" Chopper, but seriously looking for a 1995 Suzuki LS650 like yours. It looks "Custom" just by itself! I really like the shape and design.
    Thank you for giving me inspiration for my next "Customized" Bike!

    Actually I would suggest using aluminum wire for cleaning - its softer.

    Good work - looks absolutely nothing like my carb.

    Be aware some bikes can have up to four separate carbs.

    True, but the basic concept of this instructable is how to clean each one. Removing and cleaning a rail of 4 is a whole other instructable!

    Nice, a couple years back i fixed up our old 76( i believe) yamaha (no i wasn't the original owner.)
    we tried putting air through the tubes and everything wires pins whatever we could find that would fit. nothing worked, So I heard that if you boil the parts in water for a good 5 minutes it should help. So I did that and it worked amazingly. First pump on that starter and it roared.

    I've not heard of that before, but boiling parts is probably way more environmentally friendly than using carb cleaner! Good suggestion!

    Sure its more environmentally friendly but that's not the point :D I just know that it works awesomely well... hehheh
