Project "phoenix" has come to a halt...

To do a compression test you need a compression gauge. It looks like a gauge with a line coming of it and at the end of the line is threaded and will screw in to where your spark plug will go. Crank over your bike for a couple seconds and check the gauge. Do it for all the cylinders. They all should read the same.
 
Also check your fuel pump and fuel filter. You said you could
hear your fuel pump when you turn the key Right? replace old filter
could be backed up some to keep your bike running smooth.
 
Yeesh! I hope you get this figured out. You've been rebuilding your bike, right?
yep...going on two years and $6400.

Jesus.

I hope it is something as simple as a relay in the wiring harness, man. If it's a fuel delivery issue, there's a solution just around the corner. Testing with a damn multimeter can take forever though if you don't do it all day, every day for a living.

Perhaps there's an issue with the ECU wiring? The ECU controls the fuel delivery unless you've got a PC, right? To check the wiring you should be able to unplug the stock connectors under the tank and test with your volt meter, right?
Yah...I hope it's something as simple as that. I have a bad feelin about that multimeter...I'm all thumbs when it comes to electronics and wiring.


Stock connectors under the tank? You mean like the diagnostic plug an stuff?
Yeah, the plug for your injector rail. You should be able to check your voltage there, right?
yeppers...

Power is going through...but I think I need to check how much is going through. Gotta find me a multimeter first.
 
No idle...no start. She'll crank over and sometimes try to start, but she won't maintain idle. She cuts out and sputters.

More stuff


I'm about ready to give up.

Please....help a brother out.
Pac if I was you I would change things back to the last time it ran....then start your mods one by one till you find the thing that caused the problem. It does sound like a fuel issue of some kind tho. Hope this helps  
wink.gif
no mods aside from the pair valve being removed and blocked off.

The external fuel filter was a neccessity, as the old one is already 7 years old. There aren't kinks in the fuel lines, though...and the lines are clear.


Gaaaah!!!
I don't mean to insult your abilities Busa but when you replaced the PAIR valve and block offs you did plug the vacuum line correct?

Just trying to help. Walk away from it for a while and let your thought process work it out.

You'll get it!

hogger...
I believe I did. Cut new gaskets when I put on the block-offs.

Plugged the hose outlet on the left backside of the airbox, plugged the outlet on the #4 TB...

I got that correct, right?
Pac, I believe facing forward from the rear of the bike, you need to plug the big hose outlet on the back of the right side of the airbox...not the left. Its closest to the idle adjustment screw.  You mighta' unhooked/plugged the wrong hose......
Left, schmeft, same thing.

Actually, I was mistaken on that one. The outlet I plugged is on the side opposite to the IAT sensor. The other side is just some sort of catch for water/liquids in the filter.


ok..got that one right. One down.
 
I'm sorry Pac
sad.gif
sad.gif
Yah...me too, Em.
down.gif
'Sokay, though...with the collective power of the board and my mightily incapable hands, we'll get this solved.



I hope. If anything, I'll just hafta sell a kidney and turn the bike in to the dealer here for them to work on it. I wouldn't be suprised if it costs me at least another grand.

hmm....sounds easy enough!

Now I just gotta get my hands on one of those gauges.

old filter has been replaced.

Set up an external one, so I'm thinkin I have that covered.


At least, I hope so.

Best of luck Pacman... Sorry I cannot be more helpful but good luck Bro...

thanks, Revster...and no worries.


I'll get this hammered out somehow. Actually, it WILL be resolved...it's just that one way to solve it is waaaaay more expensive; i.e. dealership route.


I'm gonna try and get it done to the best of my capabilities. At least I don't hafta pay myself $70 per hour for labor.


Gonna be pricey to go the alternative route, but at least it's there. I don't really trust them, but I have no choice. Gotta bend over the barrel and take it like a...err...well, whatever. Somthing like that. Just gotta try an scramble to get the money together.

Oh well. Guess I'll be off to go mug someone.

once again..walk away..think about it and then sometime in the middle of the night you will wake up screaming and find the problem.

hogger...
 
that is possible. Although when I get up at night screaming, it's usually to go to the bathroom.

Pac have you had the bike running since you installed the external fuel filter? Are you sure the internal pump will work with the extra lines and distance of an external filter and still give you the pressure you need? And is the ext. filter the same rating as the internal? If the external flows less fuel your gonna have a BIG restriction in the system....and a lack of fuel where you need it most...your motor
wow.gif
If the filter is down way lower than the tank and/or the internal filter was your gonna be fighting gravity with your fuel flow which will also lower fuel pressure. Depending on your set-up you might need a stronger fuel pump. I hope we can get you going...you've had the patience of 10 saints.....if anybody deserves a good ride on the worlds fastest bike its you

Come to think of it, no. Bike hasn't been running since I put the external filter on.

I talked with RSD extensively on this (he had an external filter set up as well) and he said it wouldn't be a prob. 50k clicks on his bike with nary a problem.

I didn't check the flow of the external filter...the inlet and outlet fittings are smaller than the outlet and fuel rail fittings on the Busa. I'm thinkin it should still work...but I'm starting to think that I could be horrible wrong.

Guess I should take some pics of the set-up. Hopefully that will provide the good folks here with more info and enable them to get a clearer picture. Mebbe I'll also look into a pump with a stronger output rating.


Thanks for the kind words, man...I appreciate it.

I really hope that I get to ride soon...I really do.

okay...here's the answer. Your battery is falling below 12volts hence why it won't idle but it will crank. Add a charger to the battery and prove me wrong. It it starts with the charger connected.....problem solved.
did you try this yet? Even if its a new battery don't overlook this. Bike WILL NOT RUN WITHOUT A GOOD BATTERY AND OVER 12VOLTS. Bike WILL NOT RUN WITHOUT A DIRECT CONNECTION TO AN OUTSIDE POWER SOURCE EITHER (ie: battery etc)

you know, I was wondering if I responded to this one! had to look through the post again...seems to me I missed it. Sorry, bro!


I hooked up a pair of jumper cables from my little truck battery to the Busa battery. Tried crankin it over, and the crank was noticably faster. Much better, IMHO.

Only problem was that the bike still wouldn't idle.
rock.gif
She'd try an crank over, but no idle. She'd sputter for a second but then cut out again.


I'm gonna post up some pics of the set-up shortly...hopefully it'll help.
