Pop off question

[jura]

How much should be the pop-off on a LPW-ported 701 2001 Superjet?
The engine is setup for freestyle.
How to mesure?
At the moment I'm running the stock 38's with 75/137,5/stock N/S.

Thanks.

Have you thought about calling the builder and asking? He'll probably be giving the best advice for that setup.

I am guessing he'd recommend 95 gram springs.

No, Paul recommend me the 115gr springs, but before I had the 95gr springs recommend by FP. What difference should I feel when I put the 95grams back in?

I'd run what he recommends.

X2 that would be my starting point.

You can do a quick check in the Mikuni manual and it will tell you based on your N/S and spring combo approximately what your pop off will be.
