if your flat out all the time on a race track they will give more power . if your on the road id stay with the 28's as they are far better all round and as mush extra bottom end as top . The big carbs would be very damp at low revs and only come in to play in the band .

As above: Stick to the PWKS .
There's Much more to a carb's performance than mere throat size.

Pretty sure Pwk 28's are good up to mid 70's bhp. Maybe a programmable ignition would get you some gains ? Dusty  |
