[f-5snopro]

distance 660 1000 1320
mph 69.23 73.77 76.92

ive been looking at the numbers above from the shootout and i think it was a sick f-5 they tested. after the 660 mark the sled traveled another 340 ft , but only picked up 4.54 mph and this was at wot ? then from 1000 ft it traveled another 320 ft at wot but only picked up another 3.15 mph ?! and if you add the both of the distances and mph together from the 660 mark the sled only gained 7.69 mph in 660 ft ??? thats impossible unless it was sick !!!!!!!!!!!! i hope someone looks into this ! lol

rhs wrote this on "rpm for F5":

I have recently purchased a new Red F 5 with the Team Graphics.
My F 5 has just turned over 100 miles today. I was told the top RPM should be between 8250 and 8400. However, my RPM's don't seem to be consistent. It has been running mainly between 7880 and 7920. At certain times you will get an RPM of 8300 - 8360 which is giving much more top end speed and power.
Today I was out racing a 2002 Polaris XC 600 SP.
For about 15 min my Top RPM was running around 8360. At this RPM I was out pulling the 600 XC. At the 1000 foot mark I was still ahead by about 2 sled lengths.
For some reason my RPM dropped back between 7880 and 7900 and I got blown away by the Polaris. I put on another 20 miles after we were done racing and my RPM has still not come back up to were it should be.
Does anyone no what would be causing this.

I asked on that thread if anyone knew what RPM the power valves opened at on the F5. If they didn't open power would be way down at shift rpm.

Having said that the F5 that ran at Amsnow's shootout, is it possible this may have been the problem. If it was, guessing, wouldn't the Dealers prepping the machines been allowed to examine this problem and repair it?

Just my thoughts. I really expected the F5 to run better after hearing good stories here. <_<
