The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Why do you thing this carbs would be better than stock CV carbs on GS 1150 ?
Whats the advantage ?

Adam M.
 
Adam,
The difference between stock CV's and flatslides is incredible. For one thing the flatslides have accelerator pumps in them that give an extra shot of fuel under acceleration. When I switched to the RS flatslides the increase in power was such that my clutch would slip when really letting it rip. You do lose some bottom end, but once you get into the upper revs the motor just rips through the gears. When cruising along you do have to roll the throttle to keep from just bogging down. But once the power really comes on just keep the throttle pegged as you go through the gears. Even a slight twist of the throttle makes the bike jump.
 
are the RS carbs closer related to the VM type carbs on the late 70's GSs? no accelerator pump on mine...but no diaphram either. the bog thing is okay if you know how to ride with it...when it does pick up though...yeehaw :D
 
The VM's and RS flatslides work on the same principle, the throttle acts directly on the slides with no butterfly or diaphram as with CV's.
 
I picked up a set of 1989 GSXR1100 36mm carbs on ebay but have not installed them yet. Are these flatsides?

They are flatslides, but they are also CV's. RS flatslides are smoothbores and not CV type carbs. CV's rely on vacuum to raise the slides and the throttle acts on a butterfly valve. RS carbs have no butterfly and the throttle raises and lowers the slides directly.
 
can't you easily tell by the 4 screws that are on top of the cv and semi flatslide carbs???? the ones that allow the diaphram and slide to be removed.

That and the presence of the butterfly on the cylinder side of the carb.
