Hey everybody...

 

At least those of you still around to read this...

 

FINALLY got the bike back together in time for a late DV run and she won't start...All lights come on, everything seems to be funcitoning properly, gas flowing she just won't catch!1

 

As usual...any help much appreciated!!!

I mean I know how to check a harness but not sure about the HES?

 

TIA

Sure hope you made the run to Death Valley.....Let us all know who have been following your recent trevails on the site......

OK, fuel pump spins when you turn the key on (with sidestand up)? If yes, then your pump's working.

 

Are the hoses plumbed right? The upper hose (on the sending unit) is the pressurized supply:

it goes to the upper plastic manifold tube, and the lower hose goes to the lower plastic manifold tube. In the following image, the configuration is shown for checking the pressure in the fuel supply:

 

626841-press.gif

 

You shouldn't need to actually check pressure, but verify that your hoses are routed properly.

 

If they are, and you're still not firing, pull an injector out of the throttle body and see if it squirts fuel while you crank. If it does, then see if you've got spark.

 

Report back if you've got fuel AND spark but no combustion.

Since you just finished your spline lube, let's look at things which were disturbed during the operation.

 

Mitch started with the fuel lines. Is it possible that one of the fuel regulator manifold tubes is pinched? O2 sensor wire disconnected? Neutral switch disconnected? Sidestand switch wire pinched by starter? Kill switch engaged?

 

Keep your search limited to the things you touched while doing the spline lube. Retrace your footsteps.

Assuming the RID comes on, the neutral light comes on, and the fuel pump comes on, I'd say reversed fuel hoses are probably the most likely cause.

 

If those check out OK, verify that you have spark. (Please clean up and ventilate any fuel you spilled checking the hoses...and remember that fuel vapor is very explosive.)

 

Then check other stuff like the O2 sensor connector, etc.

In checking the spark by pulling a plug, reinserting it into the wire, and turning over the engine, preferably in a semidark garage, it is important to keep the plug body grounded. I believe this warning protects the coil. --Jerry

Grounding the rim of the plug while attempting to fire is indeed important; without that, voltages build up high enough to damage the coil.

 

Testing like this is also easier if you happen to have a spare plug lying around to use, instead of having to remove the particular plug that's installed in the cylinder head. thumbsup.gif

Thanks again to all for yet another speedy response!!! thumbsup.gifclap.gif

 

 

Fuel lines not interchangable!!! Who woulda thunk it dopeslap.gifdopeslap.gif

 

Bike goes Zoom Zoom now!!!!

 

Thanks again and off I goooooooooo........

Just to kind of close the book on the "why", one hose is the high pressure hose from the fuel plump in the tank to the injection system, the other is the excess fuel return hose to the tank post injectors. Reverse them and the fuel pump attempts to pump fuel the wrong direction into the system.

hey cameron

 

I am so pleased for you if i was closer i should like to shake your hand mate. I just know when i get to do my clutch there is going to be a field full of splinters from the head scratching. I hope the bike went well for you please let us all know how the machine runs .

kind regards

stay upright

Thanks for the Kudos....!!!! And to you Ken for the explination..!! grin.gifthumbsup.gif

 

Am afraid they might be a bit premature...everything was ready to got to DV until one final check revealed that the rear brake rotor was bent... bncry.gif

 

I'm guessing from when I dropped the final off the workbench doh!!! dopeslap.gifdopeslap.gifdopeslap.gif

 

Oh Well...I'll get another one of those and then maybe I can goooooo....

 

Thanks again everybody!!! thumbsup.gif

Sounds like me--struggling to work with utmost precision in the machine shop and then hit the wrong switch or lever and take a huge gouge out of the work...or drop it. Usually happens when working too late into the night.

 

Let me give you my kudos on your persistence and can-do-it attitude. And for good measure here is a Calvin Coolidge quote that I keep on my wall:

"Nothing in the world can take the place of persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and determination are omnipotent." ~ Calvin Coolidge

 

And I've been looking for more cost effective rotors and found these Ferodos. Don't know anything about them but thought I'd pass on the link. http://www.kneedraggers.com/details/Ferodo_Brake_Rotors_BMW_R1100RT--505228.html Looks like one for your bike is $112. --Jerry

Thanks again Jerry for the encouragement!! I just ordered a rotor from these guys...thanks for the tip..will let you know how it works out.

 

Thanks again

Warning: The bolts that hold the disk to the rear drive can be very tight. Make sure you have a tight fitting wrench and use some heat.

Agree.

 

A few minutes per bolt with your heat gun should make life much easier.

 

I can't comment on the Ferodo rotors, but I had Ferodo pads on my RT for a while and really liked them. They're a pretty well-known name in motorcycle brakes, so I wouldn't hesitate to try one of their rotors.

He He....

 

I used to take great pleasure in mastering difficult music...now my greatest pleasure is heating up tight bolts and wrenching them out!!!! eek.gifeek.gifeek.gif (Insert evil demented laughter ala a bad Allister Crowlery impersonation)

 

But seriously...thank you that is very useful information.

I was thinking about this the other day. Is there any reason that an impact wrench (with heat) isn't recommended? Seems like that's what we always used on the dirt bikes, and they're mostly aluminum, too. I know that heat is required to break the loctite seal (and it'd be a nasty idea to twist the nut head off the bolt by using too much force without heat dopeslap.gif), but it seems like an impact wrench was made for situations like this.
