Default 2004 550 Fan Trail Touring - horrible gas mileage.

I have a 2004 550 Fan Touring - original engine. no meltdowns or seizes (Knock on Wood!).

Anyways, given the data posted here and on the web. I decided to do some stuff to protect it from any mid range meltdowns.

1. Enlarged vent in hood where the fan duct goes. I still have to smooth out the hole a little better. I probably increased the size of the vent by about 25-30%.

2. adjusted the nut on the oil pump cable by about 1 turn. to give a bit more oil. The line on the oil pump arm still doesn't match up with the mark on the pump at WOT, but it's a bit closer now.

3. Shimmed the needle jets on both carbs so it is at clip position "2.5" vs the stock 3.

Went for a 200+ mile ride yesterday (over 12h with lots of stops) with 3 Yamaha 4strokes, 1 artic cat 4 stroke 2up, and a 2010 Rush 600 CFI.

My fuel consumption was pathetic. I averaged 9.25miles per US gallon over the 1st 160miles.

On the last stop, I put in 35.4L for 82 miles, the 3cylinder 4 stroke yamahas put in about 20L, The Rush 600 and 4 cyl 4 stroke Yamaha put in about 25L.

I am going to take the shim off the needle jet and return to the standard 3 clip position on my sled.

I googled the web, and the only post I get about fuel mileage is about 11mpg. Does anyone here have numbers for a 550Fan mileage?

Thx,
P

What were the conditions? Loose trails making the sled work more than hard pack trails? What was the air temp?

It's going to be tough to compare gas mileage to those sleds you mentioned, those are all new technology engines. Those guys are probably getting 16 MPG if not more and they've got a ton more power than your 550 so they're probably not into the throttle as much as you are to maintain speed.

gearhd6,

Thx for the reply. Trail conditions ranged from pretty bumpy in the morning (groomers weren't out too early after the Superbowl), and better in the afternoon. As the day went on, we were on trails that were recently or even freshly groomed.

The temps started at high 20's (probably 28-30F) in the morning, and fell to probably high teens by dark.



Yeah, when they get upwards of 60mph, I am into the throttle pretty good to get any speed over 50mph. Probably at least 3/4. I don't find much umph from 3/4-WOT, so I would try to keep it to 3/4 throttle cruising max.

Also, I was only getting about 80miles before I was getting close to reserve, so in the afternoon, I was really trying to nurse the throttle without falling to far behind, as it was 20 miles between gas stations.

P

Would a 6yr old belt with 3000 miles lower fuel mileage too?

i have a 700 touring edge and the gas mileage is terrible especially compared to those machines you are comparing yours to
i just changed my top gear in my chain case from a 22 tooth to a 23 suppose to make a big difference and i am going to put a set of boaster bottles as they are suppose to help as well
gas economy is the only concern i have with my sled be nice to figure it out

Your gas mileage is terrible. I can get about 150 miles on a tank, never gone that far but think it's doable. That's with a 500 Indy Trail. Similar but not quite the same as your sled.

Yeah, I played with the carbs last weekend to try to protect my motor from the "550 Fan edge chassis mid range lean out seize". I raised the needle jets with a 0.020" shim. I took the shims out last night.

Does your machine have a 12 gallon tank? According to the polaris specs available online, my machine is supposed to have a 12.25US gallon tank (46L)?

Thx for the info.

Yeah, I'm doubtful that I would get that type of mileage (14-15mpg) on my machine.

My machine is 645+lbs with a 136" track
Yours looks to be about 470lbs with a 121" track.

I'm hoping that I get 12-13mpg....

I get the same mileage, just over 9, with my sled ( 05 550 touring). Motor has been rebuilt twice (original belt lasted longer than the original motor). But I've got 4,500 miles on the third motor and 7,500 on the sled now.

Hi Barnyardbanker,

Thx for the info. I believe your sled probably has been rejetted to the team tip specs with the larger needle and needle jet, which probably makes the fuel economy worse.

I returned my needle to the stock position this week. Was out for a 50 mile run last night on pretty fast trails. I hope to post some more mileage figures soon.
