SiBag Posted January 2, 2022 Posted January 2, 2022 Expensive stuff that you can re-spaced. I've seen fcr39's fitted to a bimota SB6 Quote

Dezza Posted January 3, 2022 Posted January 3, 2022 (edited) 750W, RF900?? 750 has BST38, dunno about 900. Usually plenty of 750W carbs on eb@y, although the seller's description of the source machine is often opaque. Strange that, given that W carbs don't fit oil cooled heads without a load of hassel........ Edited January 3, 2022 by Dezza Quote

Joseph Posted January 3, 2022 Posted January 3, 2022 Oops no they are downdraught carbs like lots of modern sporty bikes. Frame shape of the RF allowed that Quote
Gammaboy Posted January 5, 2022 Posted January 5, 2022 Bandit 1250 throttle bodies fit apparently. Carb options: BST40 - most of the world GSXR1100 spec BST38 - GSXR750 BST34?36? - junk the US spec 1100s got FCRs Mikuni TMRs or RSs EFI - Bandit 1250 or respace something. I don't know of any inlet rubber swaps that let you run oil boiler carbs or carbs from something else. RF900 runs something annoyingly small, and downdraft. I think a few people have swapped re-spaced downdraft Yam or SRAD carbs onto RF900s though. 1 Quote

RF900 is a 36 too, and just stumbled onto a thread where a guy re-spaced downdraft FCRs from a ZZR1100 onto a RF, so respaced ZZR carbs may be an option there too (I have a feeling SRAD carbs would be *too* downdraft).

Hardly a feat because RF carbs are downdraught too. None of that will work on 85-95 GSXR Quote
