GSXR 1100H 1987 Carb change

Hi,

Any advice on whether this would be a good fit - Mikuni RS38-D19-K RS Series Carburetor (RS38-D19-K) - 38mm

If I go with these do the default jets and needles suffice for aftermarket k&n and exhaust or do I need to look at a dynojet kit?

Appreciate the help.

Those should work fine properly jetted. It'd been quite some time since I messed with RS flatslides but you'll need Mikuni jets (available from Sudco,etc) and no,you do not need to utilize a Dynojet kit.

I'm sure one of the oil-cooled experts will pop in and either confirm or correct me if I'm wrong

If you had the pick would you fit 38mm or 40mm flat slides?

Only race once maybe twice a year in classic festival, otherwise street riding on occasional weekend and 4-5 day rally rides.

If the engine is stock,stick with the 38's. Just my opinion though as I know folks who ran 40's on a stock 1052 but it was strictly for drag racing and he wasn't concerned with low-mid rpm response.

Are you buying new carbs or used?

Sudco's tuning manual will answer your questions.
