    92 vxr performance mods?

    I recently got a 92 waverunner vxr. I have replaced all fuel lines and cleaned the gas tank. I have been looking around for performance products to try and get a little more out of the 650. I also rebuilt the carb. I was wondering if the following were a good investment.

    Protec intake grate and ride plate.
    Tdr waterbox


    I was also looking at a solas impeller.


    Any input would be appreciated.


    Also, are the 701 and 650 exhausts interchngable, I haven't been able to find a pipe for the 650.

    If i remember correctly you can't use a 701 exhaust on a 650 bc the exhaust ports are sized differently. Old 2 stroke parts are becoming harder to find, but try GroupK or Pro-Tec for starters...

    (Correct me if I am wrong on the exhaust thing, guys)

    Thanks for the input. I'm going to order a pro-tec ride plate tonight. I was trying to avoid Engine mods like porting right now. Does anyone know how much a tdr waterbox opens the 650?

    701 cc pro VXR , Riva exhaust , ocean pro head, pro tec port job , dual mikuni 44s, oil injection removed got me to 54 back in 1993 ! those were the days. 650 vxr parts are not interchangable like metioned above stick with pro-tec back in the day they were the yamaha experts

    I just sold my modded VXR Pro that was running 51mph. They are a lot of fun but on the 650 model just do what you mentioned then ride it for a couple years until you grow tired of it. Then buy one with more power. Those hulls become quite a handful at around 50mph!
