    UPDATE

    Winch mount and winch arrived today!

    I also grabbed a few goodies like a snatch block and a quick release fire extinguisher mount as they are soon making it mandatory to have a fire extinguisher when riding in the bush up here!

    15 hours on x4 now, waiting on the 20hr mark for service even though a guy at dealership told me first was at 10!!!

    Also the yam sales guy told me to only ever run x4 on 87 octane which I thought was strange and I confirmed he was wrong tonight when I opened the hood and it says 91 on the air intake!

    Also need to get some black paint and start going around a few parts. The bolts and some other parts starting to rust are upsetting my OCD! I donít mind scratches and dents but somehow rust bugs me!!!

    Actually made me go out and check and you're right, it does say 91:



    But that's using RON:

    What Octane Ratings Mean | The Streetside Garage

    Pump values (In the US) use: (R + M) / 2

    I think the difference between R and M is around 3-5 so for example:

    (91-R + 87-M) / 2 = 89 Pump
    (89-R + 85-M) / 2 = 87 Pump
    (87-R + 83-M) / 2 = 85 Pump

    The manual calls for:

    "Your Yamaha engine has been designed to
    use regular unleaded gasoline with a pump
    octane number ([R+M]/2) of 86 or higher, or
    research octane number of 91 or higher. If
    knocking or pinging occurs, use a different
    brand of gasoline or premium unleaded gasoline. Unleaded fuel will give you longer spark
    plug life and reduced maintenance cost."

    Ah so he was correct in saying 87!!! Itís sounded strange to me and after them being incorrect about a few other things I just jumped to conclusion when I saw 91!

    I think you will be needing new spindles far sooner than you get them to rust through. If it were me, I wouldn't run sway bars all together.

    Really?? You think it will handle ok without them? Iím thinking the sudden signs of surface rust on things was from the road spray while towing it to the trails.. there was a lot of salt on the wet roads and it wasnít washed immediately!! Iíll have to remember that!

    Sway bars will keep you flat when drifting a corner, but they will make the ride miserable on the bumpy stuff. They put those on our Rhinos and we promptly removed them. I even designed new bushings for the Yamahas that do not bind and yield a smoother ride. I broke my back 18 years ago, so ride comfort is a priority for me.

    I'd unbolt the bottom and zip tie the bar up to try it out. I think you find better independent suspension without the bind.

    A good compromise would be unbolting the front sway bar and leaving the rear on (on the X4)

    That's a good idea. I would try it both ways actually. There's different ways to improve the ride with seating and such too. I went to an air seat that is stitched around a steel tube to hang and six inch longer a-arms.

    Definitely going to try this.. it got very bumpy for the passengers in the rear when we werenít even feeling a bump in the front so maybe worth unbolting when passengers are in and just donít drift as hard!!
