1: if you use the stock petcock it is backward ether the fuel line faces foward or you install it backward or you get a petcock for a 06 or older steel frame wr
2 : wr rad shrouds do not fit right you ether hog out the hole or use Yz450 shrouds
3 : the seat fitment angle is a bit off . the fix add a washer or two to the front seat mount ,trim the seat pan to match . this is not a have to but it does make it fit better
I've got the yz shrouds but have not trimmed the seat pan yet , but I have spaced it, notice the gap between the tank and seat tapers to nothing . this will give you a few more miles , but rejetting the bike right does about the same . I get around 80 miles woods riding and 120 miles road riding

Seriously... IMS 3.1 is on the top of any 07' and newer mod list. I trimmed the key hole in the seat pan and it fits fine with no washers on the tank tab.
IMS works great with sub mount stabilizers and unabiker guards too:prof:

I also have a 1-2" spacer from the shrouds to the Unabiker rad guards Saves some wrestling and you don't have to trim your shrouds

Thanks for the help guys! I ordered a IMS tank today so I could have it for the weekend! I like the fact the rad guards will work. On the stock tank I was able to add a 1/4 inch aluminum spacer under the front mount to increase the point of where I run out of gas at. It helped by 6 miles farther, but If I was racing I would just set it on reserve.
Desracer - Your petcock will be relocated forward more on the IMS. A couple different approaches to this problem.
1 - Get a longer fuel line. This works good but in my opinion leaves a lot of extra fuel line hanging out there to get caught on something.
2 - What most of us do at first, install your petcock backwards in the new tank (inside out). This will put the fuel line connection in a position that you can use the stock fuel line and everything is nice and tidy. The only issue here is that the petcock gets a little hard or ackward to operate.
3 - What most of us have eventually ended up doing, is to purchase a WR petcock from a steel framed era WR (06' or older). That will put everything in place as if it was factory:thumbsup:
Good luck, I was getting the same mileage as you with the stock tank especially in the desert. I have since mounted up the tank and leaned out my jetting to a more appropriate settings and I can get 70 - 80 miles no problem:thumbsup:
