Hi just wondering what kind of speed you guys are getting on you 98,99,2000, xc 700. I know that the speedo is off but just wondering what they should roughly hit on the speedo.,,,,,,,,thanks[/b]

I can get about 112 mph on the dreamometer on the 600. My guess with the 700, you would be looking close to 120 mph.

 

My 1999 700 was off 12 MPH from radar, best was 115 on speedo, 103 on radar, kind of a dog I thought. After I traded it, they found a broken motor mt.

 

When my 2000 xc 700 was stock it would hit 119 on an ice road. Like previously posted would have to say somewhere around 105-108 in reality.

 

I agree with all the above posts also, speedo is usually 8-10 mph off, my 98 with 25/40 gearing and the mods that I have has pulled 117 in the quarter mile on asphalt.

mine is a 700 it has psi twinn pipes ,rad valves,hotseat head,and light porting.

I could get it to read 110 mph on my 99'.

I have no idea what has been done to the sled. I bought it 3 years ago. The person I bought it from said some work had been done to it by the previoous owner, but I didn't get the details. It doesn't matter to me. The sled is used for mainly trail riding and now my son is using it. I had the first opportunity to run it wide open this year on a lake in early winter, about 2" of powder and a pretty long run netted the 112 mph on the speedo.

I have just "upgraded" to a 2002, 600 XCSP/M-10. From the initial messing around this past weekend, the 98 can kick it's ass all over the place!! Those 98's XC's are one quick sled.

 

Saw 175 km/h (110mph) on the speedo on my 99 - and that was with tow sled! on snow covered sea ice.

That was with stock clutching, which did great top end even if it took a while to get there. After clutching it, I lost a couple mph up on top, but got there a whole lot quicker.

 

Ive hit 110 with my XC7 but that was according to the speedometer. Im hoping next week to see it on radar. Ive got a hotseat pipe and clutch kit.

 

When my 99 XC700 was new with stock clutching and a little jetting I could see 118mph on speedo and still climbing. This was on a hardpack-ice road. Was hoping for 120 but ran out of room.

 

I HIT 118 ON THE SPEEDO AND STILL CLIMBING RAN OUT OF STRECH , AND THAT WAS ON SNOW ALL STOCK..<1/2 MILE>.

 

i saw 110 on speedo on a long straight trail. rpm's were too high and from my marker on the clutch sheave, belt wasnt making it to the top of the primary either. i think it'll do 110 on radar for sure.

I had a '98 XC 600 that was completely stock except for 120 studs. The sled would hit 104 mph (radar) consistently in 2000' if the air temps were cold and the ice was good. The speedo showed 110, so it was off by 6 mph. A friend of the family had a '98 XC 600, and his also hit 104 (radar).

Many years ago my son and I went ice-fishing with a bunch of my co-workers. Conditions were PERFECT, and I had my sled with me. On that frigid morning, the speedo was hitting the 112-113 mark for me and all of my co-workers who dared to hold it open across the pond. Actual speed would have been 105, I think.

My father-in-law had a limited-build '97 XC 700 twin that was faster than my 600. <edit> I don't have radar numbers for the 700, but it showed bigger numbers on the speedometer.

 

My lightly studded bone stock '98 XC700 radared at 112 every pass (keep in mind I only weighed 155 lbs) ..... I pi$$ed off a lot of big triples back in the day.... dam I miss that sled. My '03 700 doesn't feel anywhere near the snot my 'ol 98 put to the ice...

 

my 99 xc700 only hits 105 on the speedo. whats wrong

Its an old sled so most likely your clutch parts are worn, and it also depends on your jetting. Compression needs to be good.
