    Should I port these? B-pipe

    Looks like you may have a newer manifold and an older headpipe. Believe the latest pipes come opened up to 47mm. What's your setup? Might as well set them both at the optimal size for your engine setup.

    701 dual sbn 44 jetting

    Early on after this setup was together I was in the low 20's of pop off (can't remember exact pressure, tried so many variables in short time), with am FA's, it ran well down low to mid, but I couldn't use enough low speed screw to make this damn thing cold start the way I like (I refuse to have...

    701 dual sbn 44 jetting

    Sounds like you need to reconfigure your pole breathers, and/or add a vent in the hood. That alone should not effect your jetting that drastically. I'm currently reverse jetted in my '10 sj, stock hood breathers,130p 125 m, 50psi pop off, 2 1/4 turns out on lows (fine thread screws) don't...

    Plug reading

    It won't be close at all. Few seconds isn't long enough, and tied to a dock the load will change. If it's difficult to hold the ski WOT, may just wait until an ideal water condition? And I second what spark plugs said, check wash. piston wash will give you a much better overall reading...

    New Bike Day!

    Phazer 2 as in a snowmobile? Those were real good sleds way back in their day. And huge perk is parts are dirt cheap and plentiful.

    Billet Head

    Just to pick your brain, What kind of loss would there be just leaving the spark plug like that, and not fully enter the chamber? Only reason I ask is I'm thinking of how many times I have had to use the wrong plug in a pinch, ES in stock heads and HS with aftermarket, and can't tell a bit of...

    WTB: php 898/tpe1021/964 or other billet motor

    His 964 my first year at SFF made me a believer! It sure put some strokers to shame on the bottom end hit.

    So uh... what about the fx1? Seems like everyone has a very different interpretation of that ski.

    10/18 skat

    If it's a skat slimline should work pretty well.

    Superjet is very "pipey" with the new setup.

    Try a bigger pilot jet. If it blubbers, you may need to compensate by taking some fuel out of the high circuit.

    Wanting opinion on superjet

    Roundnose is top heavy, especially with that damn stock hood. Look how many aftermarket hoods and pole lowering brackets were made To remedy that years ago. Some people like the top heavy feel, others hate it. I know a handful of old farts that won't own another 96-07 hull (you lurkers know who...

    @Themist456 where you located at in Illinois?

    Wanting opinion on superjet

    A roundnose isn't going to flip any easier than a squarenose IMO. Both will be very difficult if hull is stock. squarenose SJ's typically handle better than 96-07 roundnose, but in the end will come down to rider preference. Also, squarenose top deck is very weak compared to a roundnose, you...

    Ethanol fuel 93 octane

    Retarded timing, also too late/slow of ignition, can burn valves due to the extreme high temps. and also potentially due to fuel still burning while valves are opening, similar to how with a 2-stroke too late of ignition will melt the exhaust side of piston.
