What's your front track shock adjusted to?

 

[CCC Sniper]

hmmm, not sure what u mean, unless you mean transfer block? its on 1 ( to much track, not enough ski )

 

[Craig388]

CC, Rob posted this in an earlier suspension subject, and I've read it in my race manual also that if the front track shock (shock w/ coil) is adjusted too stiff it could effect top end by as much as 5-8 mph. I couldn't believe what I read at first since I had this exact problem(loss of top end) with my POO POO last year. It all made sense after reading the manual. Too much track angle will KILL your top end. Run that front track shock as loose as you can. Have you also checked your power valves? Adjusted throttle cable, and servo cables? Just trying to help.

I have a sno pro f7 too the 1.375 track takes alot of top end off the fastest ive got is about 104 or 5 i bet the big lug track takes off 10 miles per hour

 

[got snow]

Remember, thats an accurate top speed reading compared to many "optimistic" speedometers used by other manufacturers :blink:

Finally got the F5 out on the lake today, first miles off the trailer. After a few miles of break in, it was off to the races.
Speedo said 108, GPS said 105. Drafted with my Pol xc6sp and got up to 108 on the GPS, 600 did 110 which is 3 mph faster than it ever ran. Good day, cold and had a tail wind. This little 5 is a rocket, and handled great. But then again, I'm used to Polaris handling!

I've never known a xc600sp to run 110mph. Must not have been stock. They run out of gear around 100-102.

 

[CCC Sniper]

hmmm, ill check into it i guess and keep yall posted

thx

 

[sportrac54]

I have a snopro F7 with the 1.375'' lug track . I have reached speeds of 114 mph
consistently in 3/4 of a mile hard pack lake. The trick is not to leave the track too loose as it
will rub against the top of the tunnel and slow you right down .
Check the track , I will bet there is too much free play . h34r:

 

[CCC Sniper]

ok, ill check, but this was just serviced recently as well...... but thx for the tip

My Pol 600xcsp has run 106-107 bone stock, except studs and suspension adjustments, right out of the box. Checked with radar gun and GPS.

I did not trade in my MachZ for a firecat to get "top end" i did it to get a light, quick and high jumping sled.
I guess it's different for you with a F7, but on a bumpy trail you should not have a problem with the lake racers like machZ, RX1 or SRX

And where i live we only have bumpy trails and narrow turns so i think i'm sitting safe

 

[CCC Sniper]

yea i have to wait for my buddy in the trails and alot of time on the lakes..... he gets better fuel milage though, lol

well... i just wanted to see 110 mph ( atleast ) with the 1.37 track

oh well

 

[rev them up]

CRAIG is that on the 1 inch track to???i adjusted my
middle shock to a soft as it goes and i think i lost speed
compared to having it tighten about 1 inch of thread.

 

[Craig388]

Rev, I have the std suspension with the 1" track. 144 studs.

 

[junior]

My F5 on the lake I was going 90 mph on 1 carburater and it was using 1 gallon of oil per 110 miles

 

[sportrac54]

My snopro would do 113 mph as long as the track was not loose . With the big
lug track you have very little clearance at the front of the tunnel . I changed the
track to the 1" lug style and now I get 116 mph on the speedo which radar
indicated I was doing 114.7 mph .

Sportrac54, could you elaborate on that statement a bit please. What differences did you notice in MPH with the track "too loose?" And how loose is "too loose??" Did you do your experimenting on the same day in the same conditions??? Thanks for any additional info! -- Roy
