Set up for Pro-Tec head and pipe

[doogietj]

I am getting ready to install a Mach 1 pipe and a 170 psi rec head on my boat and I am wondering who else is running a similar set up. i am looking for any tips, warnings etc. Also what people are running for jetiing.

I have a 90 super jet 6m6 cases, 61x cylinder( twice over bore) and a single 44mm carb. I already have a stainless prop. I don't know the pitch but it was in it when the boat had a b-pipe.

Thanks

UHM, KEEP THE B-PIPE on IT

The b pipe is long gone the previous owner of the ski hacked it up to fit a lamey powervalve cylinder and did not want to part with it.:frown:

Then I suggest a 125P / 145M a 2.0 n/s w/ a 95g spring in the carb for starters I always start at 1.25 turns on top and bottom then get bottom right then tune the top end. Bolt her on up and roll bro.

2.3 Needle Valve

Specs that protec gave to me. I have the same setup minus the bore. When I told him I was boring over 1 mm he told me the same carb setup will apply.
