Anyone making them to customers specs? Basically I need a stock 05 CRF450 tank but an 1 1/2" shorter in the front. Coil and sealed off rad stubs in the way.
Capacity not an issue for MX.

It's turned out harder than I thought and I still have to finish the bottom and fab the mounting points for the shrouds and seat. I should have gave it more capacity as it sits pretty low anyway. If starting again I'd make some changes.

Re: Custom aluminum tanks:
I like it. Those hand built tanks look like stealth bombers. Care to share the aluminum thickness?cryzsurfer wrote:It's turned out harder than I thought and I still have to finish the bottom and fab the mounting points for the shrouds and seat.

Custom aluminum tanks:
For the top half that is exposed to falls and such I went with .125" and the lower that is protected by the frame I went with .062". For some reason I used ~.200" for rigidity and tapping for the back flat part, but if I did it again I'd do that part different. I wanted it to look trick for the most part and not to lose any weight as there's plenty of power to handle a few extra ounces. While I wait on my engine I'm slapping an 01 YZ125 engine in a 2001 CR125 chassis. This is actually a very easy swap so far.

Re: Custom aluminum tanks:
I race an 01' CR125 along with the 87' CR500. Great chassis, slow as molasses stock. I'd love to see those pics of that swap if you don't mind. Here's an article on my 01'. We're trying to figure out which air boot works best and I'll build an aluminum airbox to match it. Project bikes are the bestcryzsurfer wrote: While I wait on my engine I'm slapping an 01 YZ125 engine in a 2001 CR125 chassis. This is actually a very easy swap so far.

How did you thread your bung? Were you able to find one pre-fabbed? I'm interested in getting a aluminum tank made, but it seems that I'd have to find someone to turn the threads on a filler neck for me, and then weld that to the top plate. I'd seen a KTM 690 filler neck for sale, but it's like $150.
Bob, do you still have something in the works for custom built tanks?
Thanks!

I had a cracked YZ tank and cut the top off to get it into work. Brought that and the cap to a machinist friend at work and had him machine it. My motor is done and ready to put it back into the frame so I can finish the bottom of the tank. Been tied up on a YZ engine into a CR alloy frame and getting my modded RZ350 back onto the road. Rode the iron frame 98 5 Hunny a lot last weekend which was a blast. Good weather is upon us.

You can get fittings that replace quick fill caps insert with an insert with a std type of cap from IMS, Clarke and Acerbis, they are between $65.00 to $69.00 USD last time I checked, at Just Tanks .com.
Or do as crysurfer did ( but take the whole tank to a machinist with the cap).
I do some alloy tanks, the pic below is a length that will do the 3 tanks I'm just about to finish.The time I spend doing this by turning handles would be better off used for other things, and if I priced my time I'd just go to a machinist , but I like to do as much of a project myself.
