Motorcycle Repair: Suzuki 1981 GS550T quits unexpectedly, fuse box, thegsresources

Question
I had the gas tank and carbs cleaned at a cycle shop and a tune-up. It is still operating intermittently. The bike quits unexpectedly while riding. I re-cleaned the tank myself (a hand full of 8-32 nuts shaken vigorously) and got a lot of gunk out of it. I have been over the wiring and replaced the main fuse box which was a mess and had been rewired (I bought the bike used). One cylinder is not firing - I suspect the ignition coil. Any suggestions would be appreciated.

Thanks,

Dave Campfield

Hi Dave,

You may be rioght about the ignition coil. Suzkis are know for their charging system failures. The below listed website has details on this common problem, and the fix for it.

Send me your email address. I'll return repair files on carburetors, and more. My email is: mshively1@woh.rr.com

If you have to replace electrical parts, I recommend Electrex USA. They have fixed Suzuki's electrical flaw.
