Brians 7/12 Posted November 11 Posted November 11 (edited) Do RS Carbs when bought new generally work as set up from the box… straight on bike & run?… obviously fine tuning will be required !? Also if so… will they work on all O/C engines straight off… whether 600/750/1127/1157 GSXR/F/GSF Mk1 & Mk2… or do I need to order for the particular model I require !? Many Thanks in advance Edited November 11 by Brians 7/12 Quote

Many Thanks in advance My RS40s worked out the box on a 1340 motor If you size the carbs for the correct engine size you should not have an issue starting it..... they come with main installed and one up and down as spares 3 Quote

Many Thanks in advance RS38 worked fine for my 1216, like said, select the right size. I would venture to say that for a totally standard engine you could use a size under. I'm thinking that it would improve lower rpm torque, thats widespread knowledge, but since they flow more than CV carbs, you may not have the associated and as big of a loss in higher rpm HP than when you fit smaller CV carbs. RS34 on a Bandit 12 engine for example could prove a good combo @Gixer1460could probably help with some engine expertise on this claim 2 Quote
Gixer1460 Posted November 12 Posted November 12 Agreed on that - a M8 with a well tuned Blandit fitted some FCR41's and had them properly set up - but, although excellent power, proved not good on the road. Changed to RS36's = night & day difference, still good power 150's hp but torque to die for! If it was std'ish Blandit say, 34's would surprise a lot of people! 2 Quote
Brians 7/12 Posted November 12 Author Posted November 12 Thanks guys… it’ll mainly be for a standard GSX1100F engine… but was hoping to lob them on the B12 engine for a bit first till I finish project 2 Quote
rodneya Posted November 13 Posted November 13 I have RS36's on my 1170 Kat with velocity stacks and Ramair socks and I had to go up a size on the pilots and run the larger jets. 1 Quote
Upshotknothole Posted November 13 Posted November 13 I have RS38s on an 1127 and they're boring in town, but they make up for it in the mountains where they can be wide open. If I was going to be sensible and it was going to spend most of it's time in town I'd probably go with RS36s for more usable bottom end power. 1 Quote
Blower1 Posted November 14 Posted November 14 I have RS38s on my 1360cc GSX with dot head. All the other parts as from the box except the one step leaner needles and smaller main jets. 1 Quote
