The carbs on my newly arrived GS450 have seen better days and I am going to have to clean them. I can't seem to find a rebuild kit for the 450. Am I right in thinking that I'm gonna have to order each individual part or gasket I need? :(

Also What chemical has worked best for you guys that had to clean 18 month old varnish and gunk out of those tiny passage ways. Considering it has been 3-4 years since I last attempted this any advice will be appreciated.
 
OK, thanks for the info.

I just had an idea. What kind of problems would I cause if I just poured some cleaner directly into the carbs fuel supply line and let it sit a couple of hours or over night or would that be to much and I have to take them apart to clean that up anyway? Than again that might eat up some gaskets or o-rings. Never-mind. What was I thinking.:confused:
 
Go to your local auto parts store and pick up a can of carb dip. It comes in a gallon can similar to a paint can and includes a basket that can accomodate one carb body and parts. REMOVE all the rubber and plastic parts before dipping. And follow the carb rebuild series mentioned by Billy. You'll also want to invest in a manometer for synching the carbs once everything's back together and on the bike.

Carb cleaner is good if the bike has not sat for very long. I think you're situation really calls for a rebuild. Here's the link for robertbarr's site. http://cycleorings.com/

Unless you notice damage once you get in, chances are other than o-rings you really shouldn't require any new parts. Just take care separating the float bowl and the gasket should be reusable, was for me on both my bikes.
 
Well I took the carbs apart sort of. I left them attached together via the mounting rail. I just took the bowls and the top of the carbs off to survey the extent of the sludge. I think you are correct it will need to be dipped. It has sat long enough for all the passage ways to be plugged with slime (varnish) and there is only so much carb cleaner (spray) can do. Thanks for the tip.
 
It would merely eat up all the rubber seals, "O" rings and plastic parts in the carbs and cause total destruction.

I'm of no help with the 450. On the plus side, there aren't many O-rings involved. It looks like there's an inlet 'T' that must be rubberized, since the diagram shows no O-rings. The inlet valve uses a washer as a gasket (as best as I can tell -- these diagrams tax one's patience sometimes). The drain O-ring is some huge thing that I don't have a copy of to measure from.

On the diagrams, I can't find a choke plunger (though it must have one per carb somewhere), and a mixture screw (again, can't find it on the diagram).

I do know that I don't have the intake O-rings, so he'll have to place an order anyhow.
 
Clean carbs again!!!

Clean carbs again!!!

Well, after several hours of soaking in Berryman's Chem dip the carbs are good to go! :-D Thanks for your advice guys. I now have to figure out why it sometimes dies as soon as I shift into 1st and 2nd gear, but I have another post for that in this tech info forum. I guess when I can get it running and driving halfway decent and I'm sure I won't be throwing money at it. I have a whole list of stuff to get\\:D/ for it.
