Fuel Starving ??

[ecthemc]

Hey guys,

Little history about the bike: Bought it in 2011 new its a 2010 In 2012-13 it was in a house fire and nearly all of the plastics were melted- However, After the fire I cut off the plastics that were warped and drove it to see if it function. It started up like the day I bought it & just looked like shit. Ended up selling the other bikes damaged and this girl sat as she wasnt paid for and wasnt covered by insurance so it literally sat from 2013 - Present

I've gone over the entire bike all the sensors work, all the electrical is good..

I got to the tank part of the rebuild and realized with the old gas in it - i coudlnt just dump it out and replace after sitting so long so I emptied it- seafoamed it ( Standard can) - dumped almost all of it out that i could from the top and put in 2 gallons of 99 octane gas.

Bike started up AGAIN like the day i brought it home- blew my mind.. However - on the test ride I got alot of delay in the throttle response - reminded me of bad carbs but never the less i powered through it to try to clear it out.

brought it back to my warehouse and turned it off, turned it on, turned it off, turned it on and let it run for a bit I wanted to make sure there was no leaks on the new gaskets and that my radiator hoses i replaced had stoped leaking and after giving it a little gas it wanted to die so i stayed off of the gas..

Long story short i kept doing it untill it died and now when i try to start it - I can hear it wanting to start - it basically is starting as long as I hold the ignition it sounds like its firing - compression is good etc.

So.. Bike wont start- wants to fire but just wont stay running..

Is this as deep as the injectors, do i swap the fuel filter ? little input before i refer to a manual etc.

I know my way around bikes I just wanted to know if this is a tell tale sign of fuel starving from the filter or injectors clogged

Thanks for reading my long winded post and preemptive thank you for your time

Definitely could be a clog somewhere, or a problem with the throttle cable. Might even be a fuel leak somewhere or something isn't connected. There is no external filter. The pump is all inclusive and replacing the fuel pump isn't cheap. I am not sure if there's a way to clean it or not. Never took my fuel pump off my tank. Have you tried starting while holding the throttle open a bit?

Hey did a little research and saw its a all in one fuel pump.. I can get the whole thing for about $123 on ebay from a 20K mile bike (used)..

TO DOS:

Un bolt the tank and make sure all the connections are good - Another idea is to take my air hose and try to blow them out and see if that helps, havent got to that yet..


As for starting it with the throttle open - wont work sounds like im bogging down the motor.. Kinda like a "Flooding" symptom from older bikes (same sound).

This is just stumping me because It started up fine - was a little delayed on the throttle response but that seemed normal for a bike that's sat idle for years- it did sit thought with old gas in it for a long time. so thats bothering me.. there was no smoke in the exhaust so Im almsot 100% sure its not the plugs.

oh and there all new cables, new controls with new electrical etc.

Ok here is an update:

I let it sit for a bit and it fired back up but it seemed like it was low on power, headlight was dim and to test the theory I toggled the brights and it killed the bike. So yeah I'm sure those injectors and or pump is slightly causing the issue but after the headlight killed the bike I'm thinking it's not charging or keeping the correct voltage. Does this set off a red flag with anyone ? Talked to a local mechanic and came to the conclusion I don't want to start going crazy with a fluke (voltage meter) I honestly am horrible with electrical so on that angle I would like to take it to him .. If anyone has any obvious solutions please let me know what I can try I'm willing to do a few things before taking it there his hourly is only 65/h though so it's kinda a fail safe.

Thanks

1. The battery may be low on charge or just worn out. Properly charge the battery (or have a shop do it - shouldn't be expensive).

2. With the bike running, you should see 13.8 to 14.4 volts at the battery terminals.

3. If it's lower than that, substitute another 12 volt battery from a bike, car, garden tractor, whatever and retest. If the voltage is still low, you may have damaged the alternator or voltage regulator.

I put a new battery in it, actually had to modify the battery box as the battery autozone supplied me was wider
He sold me the battery the catalog called for ( which out of the box was full charge).

I'll hit the battery with the fluke. Is there a easy way to differentiate between the regulator and the altanator ? Is there a circuit I can test the voltages on to figure out which sysystem it is ?

Thanks, at least I'll be able to confirm if its electrical now!

Given you had fire melt the plastics; how're the air box and air filter, the wiring insulation, and fuses? Those are all plastic and could lead to a short or ground in the wiring, or weird things going in the air induction.

All of the air intake plastics are gone (removed). it is my experience with alot of bikes ive street fightered over the years that doesnt make a catastrophic issue.

The airbox itself is fine, the wiring is fine- none of the insulation/housing on the wires are penetrated.

After the fire I drove it - it didn't have any throttle delay and i let it run for a long time to make sure the system was ok. I let it sit for 3 years since than - however it was damaged by a unknown individual in that time frame and the bike was dropped ( i apologize for not including that in my earlier posts) thus i replaced 2 case covers: Water pump cover and the other case cover. the stator i believe is on the other side where there was no damage.

I see your name is alaskanflyboy so I will assume you lived in alaska for a bit. I am from alaska myself - did you ride in the anchorage area? I used to be a member of akregulators- ever heard of it ?

any who ill post some pictures of the bike to give you guys an idea of the condition it was in and the work that has been done thus far.

update on the voltage- it is not sustaining proper voltage. it is losing voltage as it runs

 

[ecthemc]

For those interested - these are some pictures I have (all mixed together) of the few bikes that were in the fire; my FZ6R before the fire, the damage and work done to the bike since.

BTW disclaimer for the last picture: Dont do that - and that's not me. That bike was supposed to be picked up with the forks touching the swing arm - not the new sproket and chain

Sounds like your stator is bad. If the regulator was bad you would probably get high spikes of power while the bike was running since the regulator keeps the spikes from reaching the battery by bringing the voltage down to a usable level 13-14 volts. The stator produces power so that the battery doesn't drain so if the voltage is dropping I'd say the stator is bad. Not sure if it works on bikes, but when your car/truck is running you can test whether or not the alternator is working by disconnecting the battery terminal and running solely on alternator power. Never tried on my bike so not sure if it works. From what I was told before by someone the stator only charges the battery while moving or when the engine is revved. At idle RPM the stator only produces enough charge to power the lights and ignition.

Wow, that's some serious damage. Looks like your getting her back into shape. Can't say I blame you for going naked with damage like that. The cover next to the oil is the crankcase (timing chain and crank trigger). Stator may have been damaged by heat since bike was dropped on right side (stator is on the left side of the bike). Did you smack the guy for picking it up by the chain and sprocket?

 

[ecthemc]

No, the guy standing in the picture is a associate of mine, wanted to test his new forklift.

We loaded the bike to take it to our electrical guru.

In the pictures you can see my custom Aprilla RSV Mille race bike I had. The plastics were hand crafted fiberglass and they acted as a fire dampener as the fire was between the aprila and the fz6r. The sensors were smoked/electrical was blown on that bike but I still managed to fire it up. Before it sold

So the damage to the fz6r is 100% temperature damage and not direct flame damage.

It is no surprise that I am going Street fighter with this bike and for what it's been through, the ammount of smoke damage to everything from the forks to small aluminum parts getting it clean is hopeless so putting plastics on it and making everything shiny is out if the question unless I want to by hand take the bike apart and clean every part. I'm all all or nothing kinda guy so the fz6r is strictly rat Street fighter until I have something else to replace it and I can rip it apart again. Ive got a business now and alot more important financial things to worry about. I'm not that young kid who can buy/flip/race/wreck bikes I used to be
