    Yamaha superjet RN 2001 701 question

    I own and ride multiple skis...though I have far more time on my Kawasakis. I currently ride a self-rebuilt JS440/550, 440 pump driveline with 550 topend 0.5mm over, SBN44, WC pipe, new electronics, 0deg bar, quick steer etc. (see profile pic) and it handles great. It is a smaller machine but has plenty of power for my 225# frame and can power tailstand and turn on a dime. My Superjet is obviously heavier, more power, but totally stock. I'd like to improve the handling with minimum changes i.e. no cutting of the pole etc. The steering feels a little loose when riding but not at the nozzle when I test the cable movement and it tends to porpoise a lot. I know body position is most of the issue and therefore would like to maybe just swap bars to get my hands further forward. I don't want to swap an entire steering system i.e. Blowsion. I am practically laying on the handle pole to get forward but my arms are only so long...suggestions? I also have another JS440/550 (full 550 motor drop in), and just acquired another JS550 all stock 1985 for the wife (she hates the size of the Superjet and loves her 'little ski' - she previously wore out the drop in motor ski as a JS440

    Really? No replies? In the vintage kawa threads, I would have had a plethora of responses by now...even if some were not so useful. I am riding both skis most days right now, but it is a big adjustment between rides...

    I like the ride of my 650sx over my sj, but the punch of the 701 is hard to beat

    I believe he's looking for tips to improve handling with bare minimum effort.

    Things to look for or adjust without cutting and pasting... Add on parts ok also but I'm not looking to add $$1000s in upgrades.

    You can get a shortened turnplate for $50-60 bucks off eBay. then grab (or make) a set of 0 degree bars.
    I'd post in the WTB section on X-H2O.com. Tons of SuperJet guys there that are always upgrading their skis to the latest and greatest, so you could pick up their cast off parts cheap and get a lot of advice there as well.

    Find and extended ride plate to help a bit with porpoising. Going from a JS to a RN is going to be a totally different animal as you’ve already experienced.
    08 Superjet
    Limited B pipe, Girdled ADA 35cc, Toby footholds, Riva scoop and stock D cut ride plate.
