Title: Carburetor - regeneration has gone too far
Post by: wagnerosss on June 03, 2024, 02:46:19 AM
Hello everyone!

After a not very intense season on my GS500, I decided to clean up the carburetors, which worked, but had problems with slightly uneven operation. The previous owner probably didn't clean them, and the first time I only used a repair kit without cleaning it in an ultrasonic cleaner. I didn't want to move too many elements at that moment, to minimize difficulties with synchronization later, etc. At the same time I wanted to do it myself and have fun with the repair process itself. So I decided this year to remove them again and clean it properly, deeeeeply.

What went wrong? I dismantled the throttle with butterflies... Yes, I didn't realize that the screws were staked at the factory. Interestingly, they unscrewed quite easily, so I didn't realize it at first. While I can fit the butterflies to the correct carburetor, I'm having trouble with the screws.

Blue Loctite, new screws, proper support for the throttle shaft and the bolt itself, leaving the old ones and re-staking them? Maybe some of you have already done this?

I can kick myself for not reading enough about carburetor regeneration, but I haven't heard about staked screws. Now when I know it, it's obvious for me. What to do. There's no use crying over spilt milk now. I hope the carburetors can be saved.

Cheers!

Are the new screws from Suzuki or Mikuni? I ask because sometimes Mikuni uses
"Phillips electronic" spec fasteners. They can be hard to tell from metric. Computers
use Phillips spec screws.
