What do you guys think iq440 2007 for a yz250f 2008

So summer is over and i am selling my race bike and a guy offered to exchange a 2007 iq 440 that has never raced (he told me it ran about 7 or 8 gas tanks) with a big gas tank , studs, and ****...... it is not converted to trails exept for the tank and head.
It is completly stock........ oem track, pistons, nothing has been changed.

for my 2008 yz250f.......290cc big bore, port and polished head, suspension revalve.......... with brand new michlins tires and brand new oem plastics.....

I'v been ridding motocross forever and i've had bad experiences with used ones. I'v heard that snowmobiles were up much faster than motocross's do?

I can tell if a bike has been beaten up from a mile away but dont really know allot about snowmobile so this is why i want some of your opinions.

How much is this sled worth in canadian$$$ ???
What parts to check out....?
Compession how much???

Any info will be welcome....................ROCK ON

kl;

oh and i forget it was suposedly baught end of 2008...........and the track is not studded.....
