81 1200 Project

[brianinpa]

Me too Joe, me too. The engine install should be really easy with no fuel tank or swing arm in. :yahoo:

I just need to take care not to scratch anything that has already been painted. :head bang: I think I will take those parts off just to make sure.

 

[joedrum]

Lots of laugh...you can scratch them taking them off too

 

[brianinpa]

Motor is in and timed and the tank is in. Now I better figure out how I'm getting the fuel from the tank to the carb...

I'm throwing out the electrical life ring once again....

I am looking for a power source for the 1200 fuel pump that will turn off with the key and the kill switch. I was PMing Dan several weeks ago and I was just going to use a source that would turn off with the key, but I decided to go with the kill switch also.

Will the black/white wire going to the coils do that? I don't want to start poking wires, nor kill the battery looking for one. :smilie_happy:

Coil positive lead after the kill switch best place to tap in.

Isn't that the way the factory wires the fuel pump? :headscratch: opcorn:

Is the black/white in the schematic?

I looks like it, but I suck at reading schematics...

I would run it through a relay to keep load through the kill switch to a minimum.
Could power the ignition through the relay too.

 

[brianinpa]

Could one relay power both the ignition and the fuel pump or would it be better to use two?

It's been a while, but check to see if the accessory fuse doesn't fit the bill, with switch, & kill switch. :headscratch: Last time a electric fuel pump was hooked up to a guy's 1100, we had it wired to come on with key & kill with kill switch. Hit the key, with the kill switch in run mode, you hear pump turn on, to fill the carb's. Much quicker starts, a relay was wired in to make sure plenty of power got to the pump, & no wires got overloaded. :yes: Not sure if we used the accessory or not to switch on power to the relay :nea:

One would be fine.

When I replaced my fuse block, I wired my stereo directly to the hot wire for the accessory fuse.

 

[Denver]

Using that to trigger the relay, as well as your stereo, should be fine. :headscratch:Most stereo's do not require a lot of power :nea: If it does, use the relay to power both, pump uses very little power. :yes:

 

[brianinpa]

Well, I tried the stock fuel pump relay from the 1200I donor bike and had it wired in: hot lead coming from the fuse block, trigger lead coming from the kill switch and the output lead going to the fuel pump and got nothing... zip... nadda on the multi-meter when turning the key with or without the kill switch in run. So I decided to just say screw it and I bought a new relay, added a ground for the relay and then I was getting a click with 12 volts coming from the output lead.

arty:

I added a couple new wires to run from the relay to the fuel pump, and now I am ready to install the intake and carb and dump some fuel into it. I am just going to forgo installing the stock 1200 carbs and just go straight to the single carb.

 

[joedrum]

good deal opcorn: sounds like good plan to me

 

[brianinpa]

I did something right... I installed the carb and hooked up the wires, turned the ignition and I heard the fuel pump running. Bring on the fluids!!!

 

[Denver]

Love the sound of an electric fuel pump in an 1100 kicking in. :yes: Sounds like victory! :smilie_happy:

 

[brianinpa]

I may have pissed off the neighbors a little bit...

:hihihi:

Sounds good from here!

A huge weight was lifted when that thing fired off...
