No expert on the F2. I doubt you would gain very much. I would expect you would have to rejet as the F2 head is a bit free-er flowing with the larger valves. Only advantage I can think of is don't the F2 carbs have accellerator pumps? this could, in theory, give better 'pick up' ( or even make it worse by dumping a load of fuel in the F1 head can't cope with? ) personally, once you had got it all correct I doubt you would notice any difference as I would bet the F2 carbs ran leaner ( for emmisions purposes ) and so needed the pumps.

As I say, am no expert on these specific carbs, just my opinion

Also arn't the carb to head rubbers a different size? and F2 ones made from unobtainium!

Thanks lads for input I will give it a miss, wasn't phased by fit have a set of inlet rubbers still softish! would have had to fit a choke cable no biggy. You all know what its like if its there try it.   Never thought about F2 carbs and emissions good point it was in my mind if accelerator pumps would help but all points taken on board thanks, Don't want to create stress instead of fun.
Thanks again to all.
