Title: Carb differences?
Post by: Arch stanton on June 28, 2019, 10:15:40 PM

I'm pretty sure I read on here.
Something about 750f1 carbs being better than those on the earlier K,s. If this is the case. How so?

Bump.
Surely someone has a opinion on this.

I don't think they are any better or worse than any of the later (K1 onwards)  K series carbs. The F1 carbs as standard gave smaller main jets 105 as opposed to 120 in the K series, but that was down to the stock 4 into 1 exhaust. At some point in K production the tickover adjusting screw moved from one side to the other, the F1 being the same side as the later K's.
