The PO has put 10k on with no issue and it still has good/consistent compression. I'll roll the dice.

I may put a gauge on it but beyond that...I'll stick to what's obviously worked for that long.

When you think one does not heed anyone's advice, it is not up to you to ram it down their throat and continue to post your opinions on them. Give it up and move on already. If I help one person for every fifty I give advice to, I'm happy.
I'm probably going to get heck for this post, but so be it.

Not ramming anything down anyone's throat, What I said was don't discount that there is no problem. When I did all the re-development on the T660 I had, and two others, and found all the inconsistent cooling by attaching sensors before and after the front tunnel cooler, the left heat exchanger and the right heat exchanger, then doing the same to an old ZR 600 and 700 with the same cooling systems and collecting all the data and then developing a cure for the problem, I think I did a little homework.

So with all that data (which took pretty much one full season to compile and a few sensors from work) and someone, a newbie, that says he never had a four stroke sled before asks for "any advice" and then in the end thumbs his nose at all the work I did and advice to try and help a very well known problem on his sled after he comes asking for it. I say; so be it; good luck buddy. Not ramming anything. He asks for something then thinks he knows the answers, Thats fantastic. He says he took compression readings? Good, like to know what each reading is. So There is a valve adjusting holding tool you can't get anymore from Cat along with a lot of other stuff for the T660 I have to lend out for guys to use. you think I'm gonna do that now? Like I said good luck

I'm not saying it's a speed demon, but it's certainly faster than "a 55 mph machine". It'll probably do that on two cylinders...
Funny enough, I just mentioned in another thread that I did 72mph today on my '03 660 non-turbo with no passenger and 1/2 tank of gas. It was perfect conditions on a hard packed trail with no wind. I'm sure if you were going down hill and had a tail wind, it might have climbed to 75mph. Obviously this is not radar, but that's what the speedo said. I topped out at 62-63mph with a passenger and a full tank of gas.

You must be mistaken.

Apparently it's not possible...or so I hear.

Your eyes are going bad and/or your speedometer is a mid-late 90's "Dream-o-meter" and Arctic Cat still can't install a calibrated speedo. OR...your track isn't picked and you were simply spinning the track that fast.

When I finally get up north or the lake here freezes over I'll find out myself I suppose.

In just the short run I did out back I easily hit 55 or so(with a 97 ZRT secondary)...nowhere near WOT and have a hard time believing I'm only going to see another 5 mph out of it.

Like I said...the PO of my sled said he also hit 75 going across a lake and he had no reason to BS me nor do you.

I've never seen it but I wont say it can't happen in absolute perfect conditions. I know I've seen 98MPH on my turbo on hard ice/snow and under normal conditions it more like the low 90s. Darn thing just never had a C-Note in it...

It must take a long time to get there though. They hit 50 pretty quick but then just run out of juice and climb at a snails pace.

So I finally got up north Tues. We got a couple inches of snow and the trails north of Hwy 8 are open, groomed and in good condition. Wed I left the house at 11AM, drove 40 miles and never saw another sled. It's great to be up there on the weekdays for sure!

My house is right on the Bearskin trail which runs between Minocqua and Tomahawk. It's an old RR grade so there are quite a few stretches to open things up on. I answered the "Top speed" question in my case. I got it up to 70 at 7200 RPM twice. I was on a hard packed, freshly groomed and virgin trail.

I definitely saw that it got up to 50-55 pretty quickly then slowly climbed the rest of the way for sure. I'm not running the stock setup clutch(driven) either. I found a brand-new Bearcat clutch for $100 and it works great. Nice smooth shifting and handles very well on switchback trails as well. It has the Blue spring and a straight cut 45° helix as opposed to the Red/White spring and multi angle cut which comes stock.

I DO have the spring and another helix on order to try out, but from what I saw/felt...the Bearcat clutch works very, very well with this machine so will probably stick with it. Same size/dimensions in every respect other than the spring and helix so it was a "Plug-n-Play" replacement. The smaller sheaved ZR with the 53° helix and Yellow spring was too harsh. When I would let off the throttle, the sled would "snap" to a stop. I think it is too heavy for sure.

All in all, although it was chilly (4°) the sled ran great and although no speed demon, it was a very comfortable ride and drank very little fuel as well. The OEM coolant heater worked well also. Plugged it in a couple hours before I left and when I went to fire it up the lower end was nice and warm.

Good to hear all is well. In all the years I have had mine, I have plugged it in once. I preferred to see how well it starts in the cold just in case I'm out in the bush without power. 10 seasons on the original Cat AGM battery. Just replaced it this year.

I had never plugged it in so I gave it a shot. After an hour, it was stone cold so I assumed it didn't work. I took a closer look and noticed that the plug had simply come loose. I re-attached it, plugged it in and it got hot very quickly. I'll probably not make it a habit under normal conditions, however I think that on days where the highs don't make it to zero I will plug it in for and hour or two prior to startup though.
