IMS 4.0 install problem

2002 DRZ400E.   Hey all. I'm having an issue with my new IMS 4.0G tank. I have it installed now (took 1 1/2 hours to get the Emperor rad guards and the IMS tank to bolt together well) but the seat will not fit far enough up for the rear seat bolts to line up, they are still about 3/4" away.

The plate doesn't really adjust. And I was hoping to get some input from anyone that has installed the same tank to a 400E before I cut the seat plastic

And before anyone asks, yes I have hit it aggressively with a mallet...:smirk:



I have had to lengthen the seat hook on more then a few plastic tank installs...  tankhook.JPG.0de00f55365689042b03da99f87c3f49.JPG

Is there 2 models one for E and one for S,SM?. And you have the correct one?

Yes I have the correct tank for the E model. The issue isn't that the hook won't reach the seat it is that the seat hits the seat hook too soon. If I cut the plastic under the seat it will allow the seat to move up another 3/4" or so and then the bolt holes will align. Not a big issue just wanting some input before I take out the sawzall.....

I had the same problem with my Acerbis tank. it isn't the length of the metal tab its the width. measure and grind it down to the proper width and it will slide forward enough for proper fitment. see before and after pics below.

      My beater/chase the kids/farm bike sprung a leak in the 30 year-old plastic tank.  I found some exact matches on ebay for cheap... but as we know the stickers no longer stick and the tank looks lame (to me) with out some glitter on there.  So, I decided to go for a steel tank since I rarely lay it down and don’t take good care of it anyway.  So I found a steel tank listed as from an XR600R.  I knew it was not from that bike, but from the pics I knew I could make it work with some custom mounting.  It came today and looks like it’s going to be easy to do.  My question, can anybody say for certain what this tank actually came stock on?  I’ve found pictures that match the decal, but not the mounting flanges.  I’ll post a picture or two once I’m done so you guys can drool at my ‘race ready’ XR 🤣
      Used 4 Gallon Clarke tank off of my 2013 498RR.  I know it fits other Beta models but I'm not sure which ones.  Comes with its own petcock.
      $150 + shipping, PayPal preferred
      This is off of my 2013 498RR, I know it fits other models but this tank has the mounts for the newer (2014 + ) plastics.  Don't know if the earlier plastics line up or not.  It uses your stock petcock, so it doesn't come with one.
      $125 plus shipping.  PayPal is my preferred payment method.

      While fueling my XR650 the other day, the IMS fuel cap came apart and the smaller piece dropped into the tank. Doing a little research, I found two styles made of plastic: (1) with 6 squared off cogs (2) with 5 rounded graceful cogs - pics attached. Mine is the former.
      Yes, I can buy a new one, but if I can just buy a seal that would be great. Online pictures of a new cap show the same two pieces that I still have. The question is, what holds them together? Did it break or does the seal, a clip, or something else (maybe in the tank as well) hold the two pieces together?
