Yamaha triple fuel mileage, SX, SXR, SRX, Viper

I never use my gas gauge as a source of how many MPG's I get. I fill up the tank at the gas station, reset odometer, ride, fill up at gas station and compare how much gas it takes to odometer reading.


Havent filled/rode sled since. Cant give you an exact number until I refill tank. I know based on 12 gallon tank versus 144 miles and still have gas left I am getting 12+ miles per gallon.

Clutches are cold to the touch, new belt, big track defection but no racheting, bearings are new, track rolls nicely to a stop, PV's are all opening and clean, no pull thrus, no apparent gas leaks from fuel pump, fuel inlet at gas tank, cap, or breather tube.

Gas mileage sucks!

What about track lugs rubbing
 
10-13 mpg... Just depends on how hard you ride.. 02 Viper, Bender trips, Clutch kit, geared, M-10, Ect... And it uses alot less oil then the Old V-Max..

What do you consider "big" track deflection? Running a track to loose is just as bad as to tight. I had a friend with a 02 SRX that always ran his track really loose, just to the point of ratcheting , when riding next to him on a lake during some top speed tuning, his track would come straight down off drivers, hit the ground, come back up at 45', hit the rails then follow under the sled. His top speed was 105 gps. We tightened up track, speed went to 114. Just a thought.
 
Not sure on mpg, but I'm around 200-220 km on a tank, that's hard trail riding too..
I'm usually within 2-3 dollars at the pump compared to my dads apex
 
to get correct track tension, you need a lake or rail bed.
loosen track to the point where it ratches on hard launches.
then start doing speed runs.
tighten track a turn then make another run, always in the same direction over the same stretch. You will almost always see speed increase
keep doing this till your speed goes down, then loosen back one turn.
 
10-11 mpg on SLP piped Viper in normal driving (fairly agressive). I remember seeing 275km per tank when it was stock so I guess 14-15 mpg stock. SRXs get ridiculous mileage stock for the power they make, which makes etecs not that impressive after all.
