What's your range on the stock tank? 08' wr450

2 gal isn't much, I put a 3.1 IMS on my wr250r. Do most of you with 450's run the stock tank?

25-35mpg depending on rider and terrain

Searched all threads, going with IMS 3.1, same as my wr250.

Keeps the tank low and narrow. That's what I run and is the best for fit IMO.

As stated, depends on rider weight and terrain. Riders with more throttle control and/or better cornering speed seem to get more range out of a tank, understandably. Plus good jetting also helps with range.

I seem to hit reserve around 50 miles, then empty at 65-70. Riding hard. I recall my old wr426 getting around 120 miles off the 3.1 gallon tank. Waaay better mpg. Can't figure it out? I thought I'd average closer to 80 miles on the stock 08 tank..
