I just picked up a stock/uncorked 03 wr450 just wondering what other riders get for miles to a tank of gas and top mph, my gps said 83.6mph!!!! I think it stock gearing but not sure, and I have 52 miles to my first tank including flipping to reserve, I have not run out yet but plan to ride it till it quits to see what it can get. it also seems reaaaaaaallllllllllyyyyyyy cold blooded is that common? oh it has been jetted...

ps it will become a snowbike this winter!!

Your stock OEM gast tank is 2.6 gallons.

I always averaged 40mpg dualsporting on my 2003 WR450, so my fuel range was about 100 miles before switching to reserve.

If you are riding high rpms and single track, your fuel range will be much lower - but your range seems really low at only 52 miles.

I would recommend double checking your carb jets (get a James Dean kit or something similar) to solve your cold blooded problem and help with your fuel mileage.

I you have the 14/50 stock gearing, then your top speed sounds about correct.

I get about 30-35mpg in single track. Desert racing I get 50miles to a 3.1 gallon tank.

I run 14/46 and top out at 95mph on asphalt and mid 80's in the dirt.

Pull your pilot jet out and see what size it is. Should be a 48 or 45 depending on your elevation. If there is any sign of varnish on the pilot replace it. Get a quick adjust fuel screw if you don't already have one.

Mine tops out at 84 according to my Vapor computer, I've gotten 35MPG and have filled it up at 75 miles usually, not tracked it dirting. I make a loop, top it up, make a loop, top it up.

How were you riding to get 52 miles? Street, it's really low. Dirting especially hard, not bad.

so maybe I flipped the reserve earlier than i thought I needed too and I can keep going for a while, i have a turn track in my yard, and a 50ft table top so I have been just riding around my empty neighborhood (only 5 of 30 2.5-10 acre lots have homes) development and my yard, so not too hard of riding, I guess I just dont know my bike enough yet, I will just have to keep riding it... dang:thumbsup:

As stated, rider weight, terrain, jetting, riding style all add up to fuel range. Mine varies drastically depending on time of year and how out of shape I am. Better conditioning I get better mileage because I can stand up more and ride a higher gear and use momentum a lot more.

What does Cold Blooded mean in relation to fuelling? It's not something folks ever say over here in England!

cold blooded means it takes along time to get warmed up and run good, like it does not want to stay running at first when you initially start it

07 WR450. IMS 3.1G Tank. JD Jetting Kit - 45/165/Red-5

Fartherest I've pushed it was in Mammoth (~8K ft elevation) last month - 125 miles and it took 2.6 gallons to fill up (had 0.5 gallons to spare!!). BUT, I was riding with serious "range anxiety" and was babying it as much as possible. Would have done a lot better if I had jetted for that altitude.

2001 WR426 here, and I get between 30-35 on single-track depending on the trail and how hard I am pushing that day. I run stock (14/50) gearing with FMF Q pipe and all free mods. The fastest I've recorded has been 83 MPH. Not sure if it could squeeze out more if I had longer stretches of road and more guts, but I always seem to max out between 80-83 MPH, depending on the surface and day. Never tried it on asphalt with knobbies, just dirt.

3.1 gallon tank so I can comfortably ride 80+ miles before I start to get nervous.
