is yours a ZR and are you trying it with the stock 19 (13W/19S) 50 (13W/34S) (90Pchain) gearing first? according to the spec sheets the (1.0 lug) ZR uses 9T 2.52P drivers where the LT (1.6 lug) & M (2.0 lug) use the same gearing but with 8T 2.86 drivers.

B-last ZR chain case OEM Parts Lookup

looks as though the gearing is similar to some 16/17 M & XF models

maybe a lower top or taller bottom - if the chain adjuster will accommodate that alteration?

I found an 18T 13W/19S Top Sprocket, 13W 18T (19T internal) - Arctic Cat - Hi Performance Engineering which might be the ticket and they do list a 17T and other top gears for folks looking to gear up/down depending on chain tensioner limitations.

Speedwerx gearing chart fwiw...

Im going to look at a BLUE one later this week...Do they come with tunnel protectors ?...In the hands of a good tuner, I can see potential for close to 85 mph topend...with some aftermarket goodies and a lightweight rider...

the blue ones look better

85mph might be asking a bit much of the one lunger when in comparison an 85hp SP500/ZR4000 runs about that speed with 20/46 gearing in good conditions. if you look at the chart with the 400's 19/50 gearing and 9T 2.52 drivers @8K - low/mid 70's is about it without adding hp and changing the gearing - removing the battery, starter and cabling should shave a good chunk of weight, if you don't need e-start. I honestly don't recall or think I've seen or heard what the max rpm is for the 400?

there's only so much to gain with these without spending 600 $ and the best deal I've seen from Catextron recently was the 2020 Sno Pro 6000 137 for $9,995 - or the RXC for $800 more during Snowmaggedon. so, the blue one's look nice. :)

I read in the other thread someone who rode it said 7600...9T...21/48 gears...7600...with 10% o.d. can get close to 85 mph...Add a pipe with the right clutching and 85+ might be reachable with a 125 # rider...

Blue is not a very nice looking sled. Probably my second least favorite. RPM wise this engine can push close to 8000.

does it run that high on the revs? I seriously can't find a 'published' number anywhere... Arctic Cat’s Single-Cylinder 2-Stroke EFI Engine

having ridden a 500 (& 720 version) with 20/46 in both for several years in you name the condition I believe you will be very hard pressed to get these going that fast on normal snow or even hard pack without a LOT of room to run. as the Snowtech article states... The bottom end and mid range was where the power was generous and fun to use, where on the top end it flattens out. That said, the top speed capability of the ZR 4000 was still amazing, it just takes a while to get there.

heck, there are numerous threads in the Procross forum from guys with 120hp+ 600's that are thrilled to hit 90mph on 'snow'.

I have owned 3 6000s. A 2017 rr 129, 2015 rr, and still own a 2017 rxc. Not one of them were 90+ mph sleds on trails. Touched 90 here n there. I don’t consider a plowed lake real world numbers. All my sleds are set up very well. Skis aligned, track aligned, clutches gone through and adjusted just right, and I weigh 180-185 in gear. Not sure we’re you guys are riding to get these 100 cat 6000s.
don't believe it, ask Joe ZR 6000 top speed


and, the blue one's look the best :)

My dealer has 5 coming in for stock in the south east metro area of Minnesota. None have been sold yet in case someone is looking for one, for a Christmas gift. They might even have them now.
