Thread highjack alert.......
I am running GSXR 750 carbs and they are nothing but trouble, badly spaced by the last engine owner, I also have a set of carbs with a rear diameter of 32mm but not sure these will be big enough for a Pinto 2.1 running a highly modified head and RL31 cam.
What size are the 600 carbs you boys are running.

My carbs arent respaced the manifold is just made to suit the carb spacing

The zx6r carbs are 36mm if i remember correctly these seem to flow enough for 170bhp on spuds current setup and also made 180bhp when he had some cams in

Terry. just in case they of any use, theres someone advertising in today north devon journal classifieds, they breaking 2 ZX6R's so at least you get to see the carbs and no postage as local

Thanks Tony, will pick the Journal this afternoon.
