Welcome!

I'm a big fan of the KLR (Kiehin CVK40) carb. Very simple and easy to work on & parts are readily available.

If you're willing to pull it off, soak it in some hot Pinesol for about 30 minutes, totally rinse (put it in a pan and let it soak for a few minutes) in hot water, blow it out with compressed air and put it back together. About any pour-in-the-tank, carb or fuel injection cleaner will help finish it, I just go ahead and use Chevron or Shell gas with Techron.

Had the dealer the other day tell me to soak it in simple green and poke out the jets with drill bits. Place I bought it from appear to be going under, think he was the only one in the building. Happy I can come here for real advice from experienced people with these problems.

Thanks so much for posting all of your carb pics and advice Tumbleweed. It was invaluable today when I pulled the carb out of my '03. It hadn't run for over a year, it would start and idle, but that's all. Now, following your tutorial, there's fish aplenty.
I've been unable to ride for the last few years, (bad hip, new one for christmas) but plan on getting out very soon.
Thanks again.

Drill Bits? Absolutely not! The Jets could be damaged -aka enlarged - by using a metal cleaning tool that is harder than the material in the jet. Brass, or copper are acceptable for the Brass jets. Motorcyclist Magazine recently had a one page pictorial showing the basics of a carb clean and suggested using a strand or two from a Brass Brush to clean the jets. A Nice option as the brushes normally have wavy/kinked bristles, that would help break up the gunk. My stripped copper wire strands have not failed me either. Both need some cleaning fluid to work with.

Shifting gears - Good Job J.C. - I'm glad to be helping grow motorcycle rider/mechanics skills.

The float bowl screws are exceptionally soft, even with a new good fitting screwdriver you stand a good chance of stripping the screw head.

Before you start work on the Carb, head to the hardware store and pick up 4 - 4mm x 14 cap (allen head) screws (16mm will work). I spent $1.25 yesterday for 4 stainless cap screws.

I had to clean the Carb due to a clogged pilot jet with 375 miles on a new KLR.

Make that 8, 4 for the bowl and 4 for the cover.

Try a soak in some Pine-Sol.

I'm wondering if it is ok to use welding tip cleaners to clear passage ways. They are small diameter files and could damage brass jets. But I was thinking of the other tunnels that need cleaning. Probably not a good idea, but I thought I'd ask.

I would not use anything abrasive to clean ports or jets. Carb cleaner and brass or copper wire will get the gunk out.
