Yep, that's my friends 04, I gave him my IMS tank... I was jetting his bike and putting the tank on, I forgot to get the YZ shrouds on his bike. :)

Dang, I don't have one single friend that will give me bike parts and jet my bike. What a bud. :)

Are their issues with the shrouds fitting on the aftermarket tanks? Thanks!

I had no shroud issues with my Acerbis tank. The only problem I had was when I added the Unabiker radiator guards. I had to enlarge the mounting holes in the rear portion of the guards as the tank pushed them out of alignment and the bolts wouldn't thread...SC

The '05 WR's and YZ's use the same shrouds so there shouldn't be an issue with aftermarket tanks and your shrouds. I've bolted up a Clarke tank and an IMS and both worked with the stock shrouds :)

I went with the IMS 3.4 gallon tank primarily because it has the largest capacity I could find of any of the aftermarket tanks and still be rider friendly. (Please don't reply ".....but Acerbis makes a 12 gallon tank that they made fer Dakar.") After installing it I was concerned how close the fuel transfer line ( The IMS tank comes with two 90 degree fittings that screw into the lowest part of the tank on each side. A fuel line is then connected between these two fittings so the fuel on the right side of the tank can move to left hand side where the petcock is.) was to the exhaust pipe. I ain't too book smart but I is smart enought to figger out that gas and hot exhaust pipes should be kept far apart. I e-mailed IMS questioning the supplied fuel lines and if they could withstand being so close to the exhaust pipe. They replied the fuel lines were high quality and not to worry. I gave it a test run around the neighborhood with a small amount of gas in the tank and to my surprise it worked. :)
I took my bike out today to do a race in the So Cal dez and wouldn't ya know it, after fifteen minutes of warming up/ puttin' around camp the fuel line above the exhaust pipe bursts and 3.4 gallons of high octane dump on my red hot exhaust pipe. :) I thought my bike was done for but thankfully it was pretty cool out and I had about a gallon of water on my bumper and dumped it out on the header pipe.
If anyone is planning on buying an IMS tank-please be careful and invest in an asbestos riding suit. Or better yet, go with the Clarke tank.

Why don't you go out and buy some high-temperature rated tube and replace it with the ones that came with your fuel tank. I've got some high-heat tubing and since you complained about your fuel lines melting, I went out in my garage and found some high-heat tubing and placed it on my header pipe for a while after a long ride and it was a little burnt; not too much. Try an auto parts store.

I have an 04 WR450 with the IMS and a Big Gun exhaust.
My left petcock is on the inside of the tank flap miles from the header pipe.

There is only one petcock on my IMS tank and it's on the opposite side of the header pipe, same as the stock tank. The right side of the tank uses a 90 degree fitting that dumps gas into the left hand side of the tank. Some people use a Zip-Ty petcock for the right side gas line and most everyone I've talked to in the desert is wrapping their fuel lines with automotive heat deflecting tape.

Does the Acerbis 03-04 tank fit the 05 model? Anyone know?

Yes a few members have the GYTR (Acerbis) tanks on their 05's. No fit issues! :)

I have IMS tank and I haven't got any problems with exhaust, but my tank was partially melted by AIS pipe. I guess AIS removal kit will be a solution for that problem. If I could only get one :)

Yep, I've got one too. I use it with Unabiker rad guards. I had to flip the rubber grommet around on the mounting tabs to get it to clear the frame and guards and then enlarge the rear mounting holes on the guards...very minor issues. After that, it fit like a glove...SC

Sorry, this is a little off the subject, but I'm looking for a stock 05'wrf fuel tank. Anyone have one in good condition for sale?

I have brand new -05 original tank, never driver. I'm a little bit far away from your location, so delivery costs / time might be an issue :)

I'm sure there is someone closer to you :)

Just my thoughts

I have a 3.1 IMS tank and I have no problems with the exhaust, the Devol rad guards nor the WR shrouds :) , but I had the shop do them as time is something I don't have a lot of..... I presume it's been installed correctly :)

I too purchased an IMS tank for my 450 and had the same thoughts about the fuel line when I installed it. I took the bike for a short ride around the block and the fuel line had a hole burned through it. Fortunately no major incident other than walking my bike back home. I've since done some research and plan to use a heavier fuel line from the right side to the left and will wrap it with cool-tape (by DEI) which claims to resist up to 1500 degrees F. heat sheaths that I've seen online are only rated to 500 degrees F. I will try to more carefully route the line as well. I also have read up on using exhaust wrap for the header. The jury is still out on that one. The interest is more about reducing the chances of things (or me) getting burned rather than the increased performance. Anyone care to comment on the steps you take to wrap the header?

I used the heat shield that covered the tube on one of the AIs tubes so far 12 desert races and 6 long trail rides and no problems knock on wood :D

Is anyone using an aftermarket tank and the Unibiker radiator guards for an 2005 Yamaha WR450? Just wondering if everything fits. =)
