Just wondering what the best jetting setup for a 2007 PX150 would be with a SIP Road exhaust. I have the drilled air filter and sito plus at the moment.
Am I better off with my current BE5, 150A/C – or should I use a BE3, 160A/C? Any advice on the best idle jet would be helpful too. I know there's no exact answer (particularly for the main jet) as all engines seem to run differently. I just need a good place to start, as there are so many combinations I will be swapping jets and doing plug chops for years to come!
I would be grateful for any help.
