Years and Models of Carb Compatibilty?

[Ironriot]

Alright techie gurus I need to make sure on something. All carbs after 1980 on GS models 550 and up are the same right? Please tell me I'm right [-o<. I need some carbs and I found a set off a 750 for 25 bucks

1000s and 1100s use 34mm. 1150s use 36mm. The 750s and 850s use 32mm. Not sure about your 550.

Thanks for the reply. Now to go measure up my carbs.... *Where's that damn ruler*...

The 550's were 32's as well, but they use different intake boots for some reason.

Not sure if you looked at this tread http://www.thegsresources.com/_forum...ad.php?t=73723

What year is your 550??? My wife's "85" GS 550 has only 2 carbs, Don't remember what year this set up started, but I think The GS 550's were the only 4 cyl GS's with only 2 carbs.

Yeah I think that started in 85 or 84 if I'm not mistaken. Before that they used four mikuni CV carbs. Mine is an 81 by the way

650s are also 32mm.

Does anybody know what the compatibility of the boots between different models? Do they vary a lot between different engine sizes?

[Nessism]

You can compare the part numbers on line at places like Alpha Sports or Flat Out. I don't think you will find a lot of crossover since the 16 valve engines have a different style boots than the 8 valve engines and the VM carb bikes are different again. http://alpha-sports.com/suzuki_parts.htm
