keihin carb on gs450?

[stevedestitute]

I recently bought a 1980 gs450s. When I bought it I knew it had some carburation issues. It would die if you tried to rev the engine past 4000ish rpms. I did a quick disassembly and clean of the carbs and got it running to the point where it could be ridden but I knew it still needed some work. I bought a set of carbs off of ebay to use for parts as needed and brought it to a local shop to have a good cleaning done and the best of the two sets of carbs to be put together to (theoretically) make one good running set. Unfortunately, after all of this the bike still won't sit at a good idle. I saw on a Sudco site that keihin has a set of carbs for the gs450. Is this true and has anyone tried fitting these carbs and what results did you get?
Thanks for the input,

cycleorings.com sells O-ring kits, including the critical intake boot O-rings you will need. The GSR carb rebuild tutorial linked on the home page will lead you though the process. It's easy to rebuild the carbs as long as you can follow directions and not looking to short cut the process. The O-ring kit is only about $20. If you just can't do the work yourself please look up chef and send the carbs to him. He will do the job right and send you back a set ready to bolt on.
