Frustration to obsession
Ok, carbs suddenly went weird in September.
It's been a frustrating 2 months, troubleshooting and tuning this BST36SS rack. I have the bike sides off for this project, so I can test ride it, and quickly take the seat and tank off for carb access.
Haven't spent much money but many days trouble shooting and testing. Fully tuned in detail, but still it idles at 2200 rpm after full warm up. This has been a problem all along with this carb/engine combination. I'm blaming the carbs, I think they're hopeless.
Last possibility may be a worn diaphragm, will try replacing that, but thinking about replacing the whole carb rack.
Have a search on ebay for 89-92 gsxr1100 carburetor, but also considering buying a new RS36 flatside rack.
Kinda pricy at $1000 for the rack, filters, throttle grip and cables.
In comparison to cars, this would be like replacing an OEM Rochester with a Holly. An automatically choice for performance improvement.
Will be doing other track day upgrades on this bike, have a fiberglass one piece tail and seat unit (94-95 Yoshimura Superbike), and headlight panel on order from Airtech.

This wear kinda discourages me from buying used carbs, because the restoration/rebuild cost does add up. But keeping the original parts is kinda cool.1982 GS1100G- road bike

Cell phone problems....Love my old HTC M9...great phone. 3-4 years old now, but still does what I need.
Anyway, the rear case got damage, and the power button would stick in.
Now this is one of the new cameras, that the back is not supposed to be removed. But the internet provided.
Got it apart, pushed the plastic back in place, seems free. Put the back on, and good to go.
Once I get my outer, protective case back on, it should be good for a while.

I started cleaning the garage for the first time in years, and after moving, sweeping and tossing things around, I realized my 79 project bike had been neglected too long.
So, into the ultrasonic the 29 SB rack went, piece by piece.Attached Files1978 GS 1000 (since new)

Finally got around to starting up my 1980 1000G again. Only one cylinder would fire up. Pulled the carbs and they were clogged up with this black, crystal like substance. cleaned up the secondaries, emulsion tubes and fired right up. Need to do a better job if I plan on storing the bike for a while. Hopefully it warms up again!

His wife is an android, he built her himself. Sure does a wonderful job cleaning dust too.
