    I found 4 aftermarket options a year ago when I was shopping.
    4.0 IMS
    4.0 Clarke
    4.7 Clarke
    5.8 Acerbis

    I went with the 4.7 Clarke. It was easy to install. I cut the music wire cross brace in half and connected each half to the original fake scoop brackets on the frame. Stock petcock fit right. I wish it had a locking cap sometimes.
    The two Clarkes and the Acerbis were just under $200 back then from justgastanks.com.

    The Acerbis doesn't require 'major mods' to anything - I think the most people have had to do is pry the lobes apart a bit to get it to slide down over components.

    With two petcocks, you won't have to do the tip & slosh to make use of all the gas.

    with multiple drops on both sides of the bike, the clarke 4.7 has been working like a champ for me...cheap and easy to install.

    i like that idea...of cutting the wire and using that to attach to the wing attach points. i'm gonna try that out. thanks.

    My Clarke 4.7 has withstood several big impacts without undue harm. It doesn't look as good as other tanks, but is well made.

In this case what does "major" mean? What year do you have and did you end up needing specialty parts? Any advice is greatly appreciated. Be the Duck...

    Yep that's what I did. Leave the rubber bumpers on, and DON'T cut the pins. Some people raise the turn signals mounts up one hole and only use one bolt.

    Hi Guys,

    I just got my self a '99 XR600R few moths ago and now have decided to do some changes to it in order to have more range for my trips.

    I was very keen on getting the Acerbis 22L tank but every where i search for i bump into the Acerbis 22L XR650 tank and seeing that you guys have discussed about it before just wanted to check if this tank will fit my bike without needing to do any metal work on it.

    The tank looks like the one you have on the bike but dont know if the mountings from the 99 xr 600 are the same with the xr 650 and if the seat will fit just fine.

    I'll appreciate your comments.

    Any advise on which brand is better would be helpful.

    I have the Clarke tank. The only issue with it is that fuel on the right side does not flow to the petcock at low levels. While this is not normally a big issue as you can put the bike on its side to move the gas - it was a problem for me once when loaded for touring (panniers, camping gear). The bike was heavy and I needed help to drop the bike without damage.

    Hi Albee,

    That what i was planing to avoid, a friend of mine have the same problem, its just a pain in ass.

    But with the Acerbis you dont have the issue as they come with a petcock in each side of the tank.

    But apparently Acerbis discontinued fabrication of those tanks for '99 xr600's.

    Can tell you about IMS as i've never saw one in fact.

    I've got the Acerbis on my 98... no problems whatsoever. Have had it on for about 8 years now, it's rock solid even through some major dumps.

    I like my 4.0 Clarke. Two fuel would be nice though.[​IMG]

    I know this is an old post, but I just got a Clarke tank and have been wondering how to make use of all the gas considering there are two lobes and only one petcock. Do you literally have to tip it to the left to get the gas over to that side?

    Yes... and it is no big deal. When you run out... bike off... stand on the side holding onto the grip, tip the pig down a bit and then stand it back up. Some will make it out like this is some huge undertaking. I suspect they have never actually done it as it is easy:lol3

    Is there a 'reserve' as on the stock tank or do you just have to pay attention to how much is left? So you don't think returning the tank and going with a Acerbis is worth the effort? I haven't installed it yet, so I'd rather know before I put it on, but considering how many people have them and like them, it doesn't seem to be a big deal.
    Thanks for the input! I appreciate it!

    First off I like the Acerbis tank, So I think returning it and getting an Acerbis is a good idea.

    Yes there is a reserve on the stock tank, it also has some trapped fuel in the right lobe in addition to the reserve. Here are a couple of pictures of the stock fuel valve. The brass tube is the fuel pickup for the normal on position. You will notice a crescent shaped hole at the base of the brass tube. This is the reserve fuel pickup.

    One way to get all the fuel with out laying the bike over: is find a piece of fuel hose that will fit tightly over that brass straw. Fasten one end on the straw, weight the other end, and get it flipped over into the right hand lobe of the tank. Now the on position on the fuel valve will drain the right lobe of the tank. Reserve will get what's left in the left side. If you do this you might want to carry a bottle of spare fuel until you figure out what your range on reserve is, because it will likely be different than it was before. It will also be a good idea to put in an inline fuel filter, because you will no longer be able to use that filter screen shown beside the fuel valve in the pictures.

    Thanks for the good info! I appreciate it. I'll probably go ahead and use the Clarke tank for now and see how it works. I got it online, so by the time I send it back and pay the restocking fee, I won't get that much back. If I hate it, I can always pick up the Acerbis tank later.
