83 gs450L Carb

[Guest]

Hi, I've got a 1983 gs450L I want to get running. I've checked the smaller stuff off my list, so I'm on to rebuilding the carbs before looking for problems elsewhere. I don't seem to have the exact carbs listed in the manuals or online (which I found out the hard war when half my rebuild kit didn't fit). My big questions:

• How can I ID the carb? They are Mikuni, bore-size 34mm. Serial # gives me nothing on google.
• Where can I get diaphragms at a half reasonable price?

Thank you!!

they should be BS34ss carbs,
for the diaphragm, you can go somewhere like here or ebay, or even aliexpress.. ( probably down in quality as noted, ali express are hopelessiwth specs, so good luck there) the jbm place says measure you carb first, they tell you how, NOTE they rate the bs34 carb at #1 in odering mistakes as there are varations in the years.. seems 82-83 have diff part numbers accornding to the suzuki parts fiche 82 is 13500-44110 whwre are the 83 is 13500 49200 / 1350038310

we got decent ones ( so far form aliexpress real cheap for a gs250, we did NOT have to cut the plastic ring to get it on, patience and a little rubber grease and you are all good. set up with the tap / lip on the diaphgram meeting /fitting into the recess in the top of the carb so that the hole at bottom of piston is at the engione side of the needle
you can fit them without https://www.youtube.com/watch?v=gEzKSPIyGBk&t=99s
