May have issues with some aftermarket seats getting all the slots to work. With stock seat, the seat pan is flexible enough that you can bend things to fit.

May have issues with choke button fouling tank in full choke position. Generally solvable by grinding off a portion of the choke knob.

Fuel line typically requires some trimming.

Safety wire catch on front of tank is a bit tricky to fit - most leave it off.

That's all I've heard about.

Clarke tank fits poorly in several ways

I've spent some time this winter preparing a DRZ400S for offroad riding in the Rocky Mountains this summer. I've done quite a few things to the intake, carb, suspension, and controls with ZERO trouble. Every item had excellent instructions and went into place smoothly and worked as expected.
The Clarke tank was the first disappointment. The opening for the petcock had to be worked extensively to even insert the fuel pickup. The threaded holes for the petcock bolts were too close together. The tank had to be forced forward just to get the fasteners in place. Finally, it raises the front of the seat so much the cover hangs loosely in the middle, and the seat bolts are very difficult to line up.
I'll roll it out as soon as the snow melts and check for leaks. Until then I'll have my fingers crossed that this thing isn't any more trouble.
Yes, I need the added capacity, but if I could do it over I'd try another brand, NOT Clarke.

Some extra bending of the seat and fiddling with the mounting is more/less par for the course with any aftermarket fuel tank (which tends to go away with time as the seat acquires a new "set"), but this is the first I've heard of any difficulties with the petcock bolt spacing being incorrect. If you're sure the issue is with the tank (is the petcock stock?), I'd return the tank as this is definitely not normal.

I just installed a Clarke 3.9.

Had the same issue as the poster above regarding the hole for the fuel pickup not being large enough. Just had to tweak it a little, then it went in.

Other than that, no issues.

I fit some Unibiker rad guards under there and everything mounted with very little fidgeting.

I just installed my Clarke 3.9 gallon tank. I experienced some of the same issues as others. Below are the problems I found and the solutions I implemented.

1.) The rear tank bolts do not line up.
Bend the wire harness restraints near the steering column that are in front of the tank forward. Be gentle as they are not incredible sturdy.
2.) Petcock pickup did not fit in hole.
Like others I expanded the hole slightly using an exacto knife. I then smoothed the edges with sand paper. one minute job. Per instructions I then blew out the tank with compressed air and also rinsed it out with fuel to get all the remaining shavings out.
3.) Seat is very hard to get in to place where the seat bolts at the rear can fasten.
I cut about 1/4" off the tounge that is fastened to the tank. I found that it was so long that it was hitting plastic in the back of the receiver on the seat and was unable to slide as far up as needed.
The only problem I have is that the body panels on the front of my bike are no where near symmetrical now. The right hand one sticks out 2" farther than the left and it looks strange. I have no idea why this is happening.

P.S. As you can see in the photo I got the Tusk aluminum gas cap since I did read about the OEM Clarke one being garbage.

Hail_TX, I was thinking about putting the Clarke on my DRZ s and I was curious if you figured out what was going on with the right side hanging out like that. Are you happy with it now after it's been installed for a little bit? Did you stick with stock petcock?

BTW, off topic but I'll be out your way Sept 12th-14th in SHNF if you want to ride.

Just saw this. I sent my tank back in to Clarke because of the right panel sitting out so far. They are confident it was just a defect. I should have the replacement back any day. I have not heard from anyone else having that same issue with the panels so I hope Clarke is right that it was just a defect.

I saw your post on TWT. Wish I could have made it but it is a family time weekend. :)
