Re: Wasted Tuning?
I also wonder what the influence of primary compression ratios is on the performance results for any given motor, i.e. enlarging transfer feeds in casing and through transfer passage will reduce primary compression, which in itself may be of benefit or detrimental to performance.

Re: Effect of humidity and air temperature on carb performance
I was hoping that the G needle would have arrived before the weekend, however, the H needles + 8-hole atomiser have certainly helped. Sorry that I've not got more to report at the moment but the bike is certainly becoming more rideable.
Cheers for now.

Re: Effect of humidity and air temperature on carb performance
I believe your taper is the reason why you run a higher main jet that most other folks_____your GJH is the same as the "standard" JJH in terms of diameter and length, but you have a leaner taper. As the taper kicks in just before you go onto main, the bigger main is compensating for the l...

Re: Suzuki 190
Had a couple of 190 conversions,one with a 150 barrel bored out,and one with a Tv175 barrel,both went very well,but the Tv barrel had the edge. What do you think is a realistic maximum bore for the small block cylinders? The reason that I ask is that as the result of a cock-up, I received a couple ...
