Ims tank for gen 2

Hi All,

Can anyone help me with info on installing the IMS gen 2 tank. Instructions that came with it leave much to be desired.

Much appreciated.

A modest proposal:

Contact IMS Customer Service.

Otherwise, video clips may be on the 'Net.

The internet instructions leave a bit to be desired - there are photos, but the magnification feature doesn't work.
I just bought an 08 KLR - the PO installed the tank but did not hookup or retain the vacuum lines, so I carry 10 gal, but only get to use about 7.2 before condition "no mas".
Looking over these very same instructions, I think all I need is some vac line and a t fitting, but we'll see in the next day or so.
Good luck & let us know how it went.

Again, I'd think a two-way conversation with a knowledgeable IMS Customer Service representative might be useful . . . but maybe the firm has no telephone accessibility nor Internet chat capability . . . if that's the case, pity: I'd think a company would want its customers to use its product to the maximum capability available . . .

Update

Again my thanks for all your support. I have thus far been doing quite well but need help with a few finals.

1. The vacuum pipe removed from the carburetor that leads to the thermostat that was required to be disconnected...What happens to that?

2. The T connection resulting that as per instructions was moved to the left, one is the 4 inch and the other 14 inch. Which one connects to the IMS tank and what happens to the other vent?

I installed an IMS tank10.7 gallon tank on my gen2 KLR. It is not the California modle with special pollution controls.

On the non-California models the vacuum line from the carburetor Tees and goes to the petcock and the Air Injection System up on the head. The IMS internal pump is vacuum pulse powered, so you just Tee into any vacuum line and run a new line to the right side line at the rear of the tank. This line connects to the pump inside. The left hand line out of the tank is the tank vent line and just hangs down behind the engine the same as with the original tank. When the engine runs the pump always has vacuum pulses and continuously pumps gas up to the petcock.

Ims gen 2

Many thanks. I am correct in reading that to mean that both T lines from the main vacuum on carburetor connect to the petcock and I can then connect a T fitting to the disconnected line that runs to the thermostat and connect that to the right vacuum on the tank?

Appreciate your patience.

Totally confused

I just went to look at the bike and here is my situation.

I have a total of 5 lines now, 2 from the T connector running from the main carburetor, 2 that was originally connected to the petcock from the carburetor and 1 that was connected to the main carburetor vacuum and runs to the thermostat.

Are you able to tell me where to connect these to?

Many thanks

On the petcock the line to a metal elbow pointing down is the fuel line to the bottom rear elbow on the carburetor. The other line at the rear of the petcock is a vacuum line leading back and connected to the vacuum port on the front of the carburetor.

The "2 from the T connector" and the "1 connected to the main carburetor vacuum and running to the thermostat" are all just vacuum lines connected direct or by TEE to the vacuum port on the front of the carburetor.

Any one of these three can go to the thing you call a "thermostat" that I assume is the Air Injection Valve with hoses near the top of the head.

Another of these three would be the other end of the vacuum line on the petcock. See above.

The third would connect to the vacuum line on the right rear of the tank for the internal pump.

These three are all just vacuum lines and it doesn't matter which goes to the Air Injection Valve or the Petcock or the Tank. They all just supply vacuum, but don't leave any loose and open or none will get vacuum.
