I bought a 1982 Suzuki GS1100e over the summer. Not running, thought it would be just carbs and tires, but it's been taking more work than that.
The bike has a Kerker, individual K&N pod filters, and a Dynojet stage 3 kit installed. I've had the carbs off 4 times now, and the last time I completely disassembled the rack and dipped everything, and replaced all seals.
It starts easily and mostly runs pretty well, but has a bad stumble from 3 to 4,500 rpm. This should be where it transitions from the pilot jets to the main jets. Below 3000 she's smooth, and above 5000 to redline she's very strong, but the stumble is annoying.
The needle is currently raised one clip from the mid position recommended in the Dynojet instructions. The needles were raised two rings when I got the bike, so I compromised between his settings and the Dynojet directions. I'm not sure he ever had it running well anyway, given that he gave me a big box of jets and a set of plugs for one heat range higher.
I'm thinking that at 3-4000 rpm, the slides start raising and the mixture is either too rich (needle too high) or too lean (needle too low). Wish I had some way to measure the air/fuel ratio while riding it.
Anybody have any ideas?
