Had 130 miles got it up to 85mph.
Went out yesterday, have 240miles, very cold conditions
(would think ideal) only was able to hit 80mph.
Made a mark on the primary, took another couple of runs,
have about 1 1/2 inches of mark at top of primary.
Definately needs clutching
I would say something is not right with your friends F5. I ran my standard F5 yesterday on the lake. Good hard packed conditions. My F5 ran a consistant 98-99 mph all day. I would say a little less then a half mile run. I am confident it will do a little over 100, after the half mile the snow changed and was little deeper. It would slow by a few miles an hour when i hit that spot. I also compared my speedometer reading with my buddies 2001 ZR800, and when he was running 60 MPH on his speedometer, mine said 55 mph. I think my speedometer is more accurate then the ZR's. I have 280 miles on my sled and no studs.
I was racing my buddies 01" MXZ 800 across a field with about 4" of fresh snow on top of hard packed ice and my speedo read 88. BUT I was side by side with the 800 all the way and I know the 800 will go faster than 88. His studs are really worn and mine are brand new. On hardpacked roads he walks away from me but for a 500 my F5 was kicking ass!
Still havn't held it WOT on a road to see top speed but I would think 100 is about it.
I had my F5 at 88-89 mph in 1000 feet (measured). At about approx. 1/4 mile about 94-96 mph. I still have break-in gas in the tank so I would expect more with straight gas. All of these numbers are on radar. The speedo on the Firecats are dead nuts on.
Last week my i noticed my machine was only maxing at about 85 mph when it would usually max at 99mph so i changed the spark plugs and there was no difference and when i checked the spark plugs again i hit the black cap off that covers the power valve cables right next to the carb jet setting chart and i saw that the cables came off so i put em in and i started maxing at 99 again so i found my problem accidently too :lol:
