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.
