Super Jet jetting or tuning? help please 701 stock w 38's & coffman stinger pipe

[Skinz]

I just put on a Coffman stinger on my snsj. My motor is 701 stock w 38's. And I am wondering if I need to re jet or just tune. I put on the pipe and of course runs great out of water lol. I dropped it in today and it was bogging down big time and stalling the motor. Can I take the jets out of a set of 44 I have that we're originally on a 650 bored to 660 that had the same pipe. I did a wave blaster sn engine swap and took the pipe off the 660 and put em on my 701 haven't put the 44's on because I need a manifold for them all I have is the stock 38's and manifold as of now was going to put the 44's on when I buy a new head and do it all at once​

Opening the top screws would likely help but upping the pilot jets and or dropping the popoff slightly will be required. You need to learn how to tune if you want a decent running ski.

Ended up going w 135 an 75 jets from the ski clinic that's what they recommended. Dropped it in the water and it was close need to adjust the high screw and should be set
