125-200cc IMS or stock WR

I am a proud new 2013 CR125 owner. Need larger tank. I know its been discussed in here but which one? I would rather buy the IMS for the 1/2 gallon or so over the WR. Been reading about fitment woes though. I have one on my 07 with no issues. Those of you that had fitment problems did/would IMS stand good a for replacement? Thanks for any insight.

Oh yea did I mention? This bike is AWESOME!

I have a '12 WR with the IMS tank. I had no issues fitting the tank to the bike. The seat is a little more of a snug fit than with the stock tank, but no problem. The only quibble I have with it is that the shape of the tank around the filler cap interferes with the left fork leg on full left turns. I pulled my steering stops way in for tight woods, and I have to readjust the left stop out a little more so I'm not banging on the tank.

I also did not find that large a volume difference between the stock WR tank and the IMS. I measured mine as 0.24 gallon more than the WR.

Really, so what volume did you come up with for the stock WR tank?
Also, that is the only issue I had with the 07 IMS tank but the steering stops are ground down for tighter turning. Was always going to use a heat gun and remedy it but.....never did. It just won't go completely to full lock. Bumps the tank.
While I've got your attention. That conversion you did with the CR125 ignition w/KTM lighting coils. Will it work on my 2013 digital ignition as well? Thanks,

I've got the old ims on my '09. Seat is a pita to get on, sometimes to the point where I need to loosen the tank bolts to get it to fit. In addition it pinches the crossover hose for the radiators although that could be remedied by lengthening the hose.

The left fork leg also hits it quite a bit. I haven't turned out the steering stop and it hasn't caused any issues after many crashes but it seems like something bad will happen sooner or later. I hadn't thought about reshaping it with a heat gun, maybe i'll give that a try.

As far as the ignition goes, as long as the stator is the same it should work. I think i'm going to wind mine up myself. I've done a few on other bikes and it's fairly easy.

I've found fitment of the IMS tanks is a crapshoot. The 1st one for my '09 fit pretty bad, like uranys the seat was almost impossible to get on. After it leaked IMS replaced it free of charge and the new one fit much better. Just put an IMS tank on my YZ250 and again the seat is hard to get on and 1 of the shrouds doesn't line up.

That's why I bought the WR tank from Hall's, no fitment issues, looks like it belongs, and no capacity increase with IMS's new tanks due to the fuel injection remold for the 4t Huskies.





The only advantage I see with the IMS tank is if you want white.

The old CR ignition was digital - the same more or less - I believe so yes it should work
The WR changed to digital not CR

Thanks

If you end up picking up a larger tank, let me know if you want to sell your stock tank.
