I have a Summit 700 136", pretty sure it is a 2000 and I was wondering what are the good and bad things about the sled? Are there any issues that I should fix with that particular sled?
The good and bad of the 700 Summit

I have an 01 Summit 700 with a 144" track, and love it. I put around 350 miles on it last year after I got it and never even fouled a plug. It has 2800 miles on it and i'm pretty sure it has never been opened up. I think it has plenty of power and goes through deep snow pretty good.
Make sure you check out the carb boots, they are know to go bad.
Another thing, the sled has 4000 miles on it, I plan on putting a new top end in it, but should I replace anything else?
If you are going to rebuild the top-end, with that many miles you better split the case and check the crank PTO bearings. My bet is that they are dry as a bone....
x2replace or atleast repack the crank bearings , case o beer says there very dry!!! mine were bone dry , spalled and takin a crap at 2300 mi. not too hard and worth the time. love the sled and still own it, little bit of work and would almost run with the 8's
Why would the crank bearings be dry? Aren't they lubricated by the injector oil?
I have a 2000 700 151" that runs very strong. I have been very pleased with it and am giving it to my 13 year old daughter this year.

The PTO bearing are packed w/ isoflex grease. As said before with that many miles they are going to be dry. I tore mine down every year to make sure thay had grease, had around 5500 miles on it when I pulled the motor & still ran strong. Good sled with a bigger track, lower gearing & a Team secondary.
'Doo "permanantly" lubed some of the crank bearings by packing them with iso-flex grease, rather than relying on normal lubrication. I am sure somebody on the 4m would have the reason why... But anyway, after many hard miles, this grease dries up, gets hard, and goes away, leaving you with "dry" bearings with little to no lubrication. Then you have a time bomb on your hands....tick, tock, tick tock.. I am not sure how long 'Doo intended for this form of lubrication to last, but I feel that every couple of years, or whenever you have the engine opened-up for a top-end job, you really should dig deeper and inspect the bearings. Some bearings last an incredibly long time, and I have seen others go at around 2000 miles. I believe it really depends on how hard the poor motor has been beat on. Apparently, you MUST use the grease specified by 'Doo, and if you buy some from them, they seem to think that it is worth its equivelant weight in gold. I think around $50 bucks for a little tiny tube. There have been numerous threads about other suppliers for this miracle grease, and if you do some searching, you can find it for around $15-20 a tube, if I recall.
