Swapping to dry sump - frame?

Coast to Coast
Any of you swapped to a dry sump engine and used the frame as the oil tank? The motor I'm looking at holds just over 2000cc of oil and I think I could connect a sealed off top tube to the motor.

Is keeping the oil away from the fuel tank the best bet? And the replies that say "just buy an oil tank" are pointless. If I wanted to go that route I would.
 
Well... First up...

What bike/frame/motor are you talking about. There are multiple factory bikes that use the backbone as the oil tank. Need more info from you to really help though.
 
My SR500 is oil in frame. I like it.
I don't see any reason to keep it away from the fuel tank? The SR tank is directly under the fuel tank.
 
Many of the Brit bikes from the 70s had oil in frame as does the SR500.

They are not generally regarded as well implemented (at least the Brit bikes, that is).

Have you considered an oil tank hidden inside the gas tank?
 
Sr500 or xt550 motor into an SR250. Suzuki gt380 tank with boatloads of room under because that bike is twin spar.

I think I can hide two fabbed tanks beside the spar that the tank can hang over and connect them to the spar as well with fittings. Should be 2300cc worth of room there.
 
The only way you'll be able to use the frame in that setup is to completely cut a section of frame out, fab a tank that structurally sound enough to replace said section and weld it all together. The inside of your frame is rusty. I gurantee it. You'll never keep the oil clean, nor will you be abke to easily close off a section of the stock backbone.
 
Yep. Even the tenere 650 motor can fit. Some brackets, stuff the carbs in there and it's on.

Here is the XT650 motor in an SR250:

That's a deal. You'll spend that much in materials to fab your own setup, and with no 100% guarantee it'll be strong enough.
