    RN 2003 - B Pipe rubbing on sponson bolts

    I will get it welded. But relocating sponsons sound like abit of work.. the ski is newly painted. What about grinding the sponsonbolts 80% down(leave a about 30% of the locknut), sand them round, and then put turf along the side of the hull where the pipe hits and over the bolts? Cant imagine...

    Superjet - Bogging down after 3-5 mins at full throttle

    Lot of good theorys here, thanks! I guess i Will start with plugging the hole in the chamber. maybe the engine didnt get enough air because of the leak, and thats why it died? Do you think jb weld will do the trick or should i get it welded at a shop? I did a compression test today, 158PSI...

    Superjet RN - Leaky midshaft housing

    Hi, My superjet (RN) got a leaky midshaft housing, when the jet is sitting in water i can see a small stream of water coming from the rubber between housing and bearing. Not a big leak, i would guess it could sit at least 2 hours in water before it starts to get serious its no problem while...

    RN 701 B pipe carb settings(noob)

    Do you have any recommendations compared to stock? Before b pipe the idle was good, never died, and not to high. What is typically changing with b pipe? Do i need to turn idle up or down compared to stock? This forum is awesome! Would never made it without it Best Regards,

    RN 701 B pipe carb settings(noob)

    Ah! Im a moron.. I read the b pipe manual, and for some reason i misread the high speed setting.. see pic. I thought that meant 1/2 turn, but off course 1 1/2 turn. So i turn high speed to 1 1/2 turn out and hope for the best! Appreciate the reply:)
