How fast have you guys had your 700s going on snow? When you reach these speeds, what RPM are you running at? Should I be closer to 7900 RpM or 8100 RpM on the tachometer, at which will I be making more power?

The fastest i've had mine going was about 118-120 on a very hard packed/icy road.

I also had it going ~110 on a railroad grade.

PS. *It's stock with 144 FasTrac studs.

i had a 2000 700 and fastest on the lake was 101.

Really? *My friend has a &#39;98 Formula Z 670 and I have seen over 105 on his speedometer in a medium size field. *I&#39;m sure on a lake it would register faster than that.

By all means, I&#39;m not saying that was true speed....I&#39;m just saying that I&#39;m suprised that you&#39;re not seeing faster than 101 on your speedometer on a lake. *Maybe your speedo is really accurate or something.

the doo speedo&#39;s are pretty accurate.I have seen 110 on a rail trail by speedo(104 on gps).on trail this year short runs I seen around 100 speedo(gps verified it to be 93.4 mph).tach reading right at 8000 00 mxz with 2800+ miles and 144 woodys, boyesson reeds and 260 main jets.

dooman,thats a few to many studs for me,1440 LOL

On my 02 MXZ 700,I have seen 111 mph on my speedo @ 8000 rpms.That was on a lake with a full tank of gas,I weigh 245# *Sled has 120 Sabers.I&#39;m sure it could faster if I good hardpack and lost some weight. http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/confused.gif

on the hardpack trail AFTER amsoil put in 179km on my 02 700 mxz 144 studs for just a second i got too cold and let off.held it to the bar for maybe 20 seconds.i am going back to cochrane to retest this i will let you know how it works.i only weigh 145 and had 1/2 tank of fuel http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/tounge.gif

I think i just figured out why my sled is not as quick now.lol ,but I did correct that

112mph here, down an icy,long road
