Already has the lighter bulkhead and tunnel, long track and skid, drop & rolled chain case, ect. Definitely worth looking into. http://www.snowest.com/fusetalk/mess...ighlight_key=y
Starting in 99, Cat upgraded to the wider 15 sprocket. I also did order the newer upgraded chain w/ my gears. I hear it's hard to break this set up. I actually decided to go a little lower than I'd planned. I'm going w/ a 18 tooth upper and a 40 tooth lower, putting me in the neighborhood of 77.8 mph @ 9000 RPM. This sled will fly up the mountain w/ those gears...

Unless just the T-cat did, none of the cats came with a 15-wide top gear except the sno pros. 18 is also a really small top gear. I wouldn't personally go any smaller than a 19.

18/40 is 2.22:1
19/41 is 2.15:1 and 80 mph @ 9,000 rpm
0r
20/43 which is 2.15:1 and 80.4 mph @ 9,000 (this is also a perfect fit in which you don't even need to run the tensioner)

Just seems like a lot of power behind only 18 teeth.

I'm absolutely not above being ignorant. I allready ordered the gears, do you seriosly think it will be a problem? Keep in mind this sled is mostly stock in the motor, right at 172 honest horses. Only mods I want to do is DD pipes w/ a can...

I just wouldn't run one that small. I'm sure people have done it without problems, but it's one of things you just do for piece of mind. I'm not sure if you've ever seen an 18-tooth gear in person, but they are very small, even compared to the 19-tooth.

If you already ordered it then just run it and check you chain case fluid often for signs of excessive wear. I'm in no way saying it's guaranteed to fail(don't want you to think I am), just expressing my .02

also I think you're right, from what was explained to me by the service tech mike, the t-cat changed in 99. He said they had allot of the older sleds w/ the 13 wide sprockets and chains comming in w/ broken chains...

You can run 13 wide on the bottom gear, but I would stick to at least a 15w 19t top gear.

I've thought about HVYO setup, but I watch my chain case pretty close and haven't had any problems. Perhaps I'll do that this season.

I run 19/43 on 8t 3" extros @8000 rpm and I think it's just right.

Well like I said I ordered the 15 wide 18 tooth upper... I guess we'll just see what happens....

Schu, Hyvo is the way to go for sure. If you compare side by side to oem cat gears, you can visually see that they're stronger.

A HYVO 13 wide gear is supposedly 30% stronger than a 15 wide cat gear. That is a HUGE difference, especially if you're talking big HP numbers.

Default Re: Looking for a sled. (questions)

Old suspension was pretty slumpy so today I ordered new Kimpex shocks , along w/ new front springs. Thought about upgradding to fox floats or to a remote resivour shock, but I'm trying to keep my spending to just the neccesaries. Also ordered a Holtzman ATACC. Then I ordered a Clutch tunning and theory book (thanks schu). As soon as MCB performance opens on monday I'll get some D&D pipes and and MBRP can in the mail. Only thing left would be a digitron digital guage for EGT's. I just havn't decided wether i want to spend that kind of money for EGT's. I'm confident that w/ reading plug color and piston wash that I can tune my sled to a the high performance level that I want and w/ the ATACC I can keep it there. Yet w/ all the money I'm putting into this sled I guess I'd be stupid not to have EGT's

Default Re: Looking for a sled. (questions)

Well I finally finished up the suspension and chaincase... Still needs a little carb tuning but it's close. Scary close. So I unloaded the machine and pulled it around back of the house. The thing is stupid loud w/ that new MBRP can. I just tapped the throttle and my new gears and crisp mid range brought the front right up into the air. Now I'm super stoked to get this thing out on the hill and see how high it will climb. Having a new M to just pour oil/gas into and pull the cord has gotten me lazy on the mod. But hearing that fresh 1000cc rip and feeling the pull has me dying to get that 151 on the hill. I just can't wait to see my buds face when I blow past his XP's high-mark... "you just got spanked by an eight year old arctic cat!" Nuff said, I'll post pics after the weekend of the climb.

Wow, all I can say is wow... Grabbing a handful of that throttle is absolutely un-real. I just happend to get my jetting right before crashers today, the sled ran absolutely incredible. I litteraly have 30 miles on the motor, the rings havn't even seated. And it absolutely flew up the mountain. The thing catwalks like it's a joke! I couldn't be more pleased w/ the performance. The gearing w/ the 151 track is perfect. The front suspension needs some adjustment, but other than that it seemed flawless. I'm so pleased that all the hard work and hours have paid off...
