My Suzuki S40/LS650 isn't starting, or starts but wont idle. I also noticed that it's dripping fuel after I try to start it. I have an idea that it's the carburetor and would appreciate any suggestions. I'm going to try to remove/disassemble/clean and reinstall the carburetor myself, and wonder if there is something I should be looking for, or something that needs to be replaced. Many thanks
Sounds like the carburetor, float, and/or float valve may be dirty.
NOTE: A service manual will be extremely helpful as you go thru this process.
There is no reason to take this carburetor apart and not rebuild it. So, get a carburetor rebuild kit, which contains the necessary seals/gaskets and other items needing replaced.
After disassembly, all of the main parts need to be cleaned with carburetor cleaner. Look for blocked passages and for areas where there is/was residue to ensure it is all cleaned out.
There is some good information over at SuzukiSavage.com for many maintenance topics for LS650, S40 bikes. There are also a few "how to" videos on YouTube.
