Greetings

We are Absolute PowerSports NH in Gorham NH. We have installed a Hannigan trike conversion on a 2005 K1100LT (our first BMW conversion) and the bike will not start.

We are a Honda and Yamaha dealer and do not know much about these bikes. It is a long ways to the closest BMW dealer for help.

So here is what it does.... the motor has spark and will run on starting fluid. When you turn the key on you can hear/feel the fuel pump run. The starter spins over and as noted it will run on starting fluid.

In addition to the pump running we get a flashing warning light in the dash when we turn the key.... an exclamation point inside a circle. We also get all of the running lights including the blinkers on steady.

During the installation process we started the bike after the rear suspension and body were installed and the bike started and ran for roughly 30 seconds before we shut it off thinking all was OK. Once assembly was complete we again started the bike, it ran for a only few seconds and died out like it was out of fuel. The bike has fuel.

The kit includes and auxiliary fuel tank. The auxiliary fuel tank is a transfer system to the main tank. There is a separate manually operated fuel pump that is used to transfer fuel from the aux tank to the main tank through the return line from the main fuel pump located in the primary tank. This should not effect the main fuel pump or the fuel injection. However, the motor in not getting fuel.

The kit installation does not require any re-wiring or wiring changes.

We are looking for help or suggestions.

Thanks

Jim

they stopped making K1100LT 1998 - if it is an 05 it is a K1200LT which is a very complex beast - lots of interlocks and the security system can cause a lot of grief

NO fuel, tells me you might have run your transfer pump to the pressure line instead of the intended return/low pressure line. Check your pressure line on the left side of the engine. I bet you have no fuel coming through the hose. Also, check inside the tank to make sure the filter didn't work loose and make sure the pressure line has no slit/leak/ in it. Sometimes if the tank is below 1/2 full you can turn on the key and listen for fuel squirting around in the tank. You shouldn't see a swirl of gas moving around nor hear gas squirting. The pump only runs for a few seconds. It won't continue running ieven if there is a leak. An 05 is old enough to need a new hose going from the pump to the filter. Pretty common leak.
I just made that repair on an 05 a couple months ago. The hose was even goey and held no pressure. $16 fix as that's the usual cost of a short piece of hose for inside a tank.
Good luck and hope I've put you on the right track.

And while you probably already know this, fuel line inside the tank must be immersion rated and not just standard FI hose. I agree with the previous post. Likely you hooked up to the pressure side of the FI rail. Only other thing would be to ensure the fuel line quick connects are fully seated.

First BMW conversion? Did you all offer this guy a discount for being a guinea pig, or was it one of those times the customer begged and twisted your leg until you said "okay, we'll do it!"? :D

Maybe someone saw big dollar signs when they gazed upon the out-of-place customer with a BMW?
I took my LT to my local HD shop just to get a state vehicle inspection. One of the mechanics whimsically shared with me how one of the service advisors was drooling, while mentioning out loud how he'd love to sell the owner a couple of tires and the related labor to change them. Apparently, it's a real gravy job. ;)

At least you're honest Jim. :wave Welcome to the forum! :bmw:
