250-500cc IMS Fuel Tanks

I am thinking about putting an IMS tank on my 08 wr250. Can you give me some pro's and con's about either going with the 3.4 or the 3.9 gallon tank. Pictures of the two different tanks installed on your bikes would be appreciated.

Go 3.4IMS. Got one on my '06 WR250. She'll go 90 miles before reserve.

Thanks for that.

Does the stock WR 250 gas tank have enough capacity for a 2 hour hare scramble, without refueling? If so, about how far or how long of a range do you have?

Nobody knows?

I am not sure on the 250, but on my 125 I have ridden 31.5 miles at race pace(about 2hrs10min) and had about .75 gal left. So figure 15-20 mpg depending how hard you twist the throttle.

I would say not if it is a open HS. I can rarely make it 2 hrs on my 125, and thats in tighter midwest trees. Not 100% though. Depends on the rider level and course I would say.

Very true. I am also running a PWK, some have said they get better mileage over the TMX. The course was a 10.5mi loop with about 7 miles being tight woods(1st/2nd gear). Also, the leftover fuel was more like .6 gal now that I think about it(remembered draining the tank into a milk jug).

anyone know if clarke makes a big tank? i looked on rockymountain but they didn list anything.

This should fit a WR. The fitment of my 3.4g IMS is far from perfect on my '06 WR250....
