I am fitting a 25mm dellorto phbl to a 150 barrel bored out to 175 and wondered if anyone has any jetting advise, please? It will be through a standard airbox.

I have used a 25mm on a 175 kit with the following settings, but was running open mouthed.
MJ - 98, pilot - 51, atomiser - AQ266, slide - 40, Needle - D22 2nd clip. this was set up on the dyno and runs really well.

The owner has just fitted a foam filter on the bellows and had it checked at the weekend, I'm just waiting to hear what had to be changed.
