HELP! 2002 R1150r Problem

Postby carknut » Wed Sep 12, 2018 12:00 pm

Hello all long time lurker new member thanks!

I have a problem with my bike that I cannot figure out. The story goes like this...

About a month ago I filled the tank and took the bike on a 70 mile evening ride. No trouble at all on that ride. The very next time I tried to start it 2 days later it wouldn't start and idle. The bike would crank fine, but only start with the throttle cracked open (like a loaded up 2 stroke) if you let the throttle close it will just bog down and die.
Things I have checked and replaced are:
Verified throttle cables are in their seats.
Fuel filter and all lines in tank.
checked the operation of fuel pump.
pulled injectors to verify they are pulsing.
pulled and grounded plugs to verify spark.
New plugs installed.
checked HES, I did eventually replace it with a brand new bosch.
cleaned airbox and filter. verified there were no obstructions.
pulled cat and exhaust to make sure there were no obstructions. ( I have a young son)
verified battery voltage at 13.4 (odyssey AGM)
pulled fuse 5 and reset motech. (not sure this applies to my twinspark model)

With all this the bike drips fuel out of the exhaust junctions. while trying to start Not sure if that means its overfueling or if the multiple attempts to start have just filled the engine. I am at a loss, and am about to part the thing out I'm so frustrated. I have no dealer within 4 hours and no gs911.

Mercy street gang.

A shot in the dark - ¿ even at 13 Volts y pico, maybe the battery isn't up to scratch when under load ? Some intelligent battery monitors don't really charge the battery to full capacity, especially if it's of a certain age. Try giving it a full whack with a beefy charger.

Otherwise, with a twin-spark bike, I'd ALWAYS suspect the stick coils in any instance of iffy, intermittent or irregular starting or running.. Especially f the bike has been subject to damp storage. Every twin-spark this-century boxer except the very latest models has the very same stick coil, so if you know another boxer owner, try seeing if you can swap out his stick coils for a try-out. Be careful pulling off the cap if you don't have the nifty alloy tool. The plastic one in the tool-roll snaps for fun.

This is the list of people I'd trust with my bike

Hi Sykospain, I messed up my bike is not a twin spark It's an 02. No stick coils. If the battery cranks good and hard, It should at least want to run right?

Man! allot of work just pulling the tank and filter pump plate!

Have you messed with the blue painted throttle stop screws?
That is all I can think of after all you have done.

It will run and take throttle right? I mean the only problem is that it won't idle??

The ecu is VERY rarely the problem itself, but maybe some corrosion in the connectors.

If it won't idle but runs otherwise it seems to be a throttle stop issue.I have seen exhaust/intake clogs (rats) cause similar problems.

Keep us up, a strange problem! (the best kind) we may learn something new.

Hi Kirby.

The bike will start and run with open throttle at 4k rpm+ but then end up stalling. If you close the throttle it dies instantly. It also sounds 'rough" I haven't tinkered with the throttle bodies other than pulling the intake runners back to verify both butterfly's were opening. (they were)

So start and run up to 4000 rpm and then it stalls? Or close the throttle and it dies. Both?
It really is strange. My first guess is clogged fuel filter, or intake/exhaust blockage.

You did state that you checked that the cables (at the throttle bodies) are seated?? yes?

One other thing is the TPS on the left TB. If it is sending bad signals to the ecu it could cause all sorts of craziness. Make sure the connections are good at the plug to the TPS. Clean them w/ something like DeOxit (what I use). It can be checked if you have a good digital multi meter and the wiring diagram. I am away on a trip and have no access.
And make sure the cables are also raped around the throttle wheel on the TB.

I can confirm the cables are seated. I can start and rev the bike to 4k rpm but then it will stall. with the throttle closed it does die instantly. I wonder if its not the tps or fuel pressure regulator.

Doesn't make sense. Even if ridden hard and put away wet after 70 miles, there's nothing that would spontaneously combust to leave you stranded 48 hours later.

But it seems combustion IS the problem.

Bad gas or water ingested? But you pulled tank and dissected. New gas afterwards?

You've turned the bike inside out.

Rotates freely with plugs out?

Nothing plugging intake runner?

TPSs don't normally fail unless damaged or becoming very wet. I damaged on on a gs crossing a stream and the engine would not run at all almost.

Did you ever use a high pressure washer on the machine and get some water in the tps? (I hate theses washers and used without discretion they can wreak havic on electrical connections and bearings)

Where did you fill up? It sounds to me like a (very) bad batch of fuel.
Have you emptied the tank and refilled from a known good source? (eg a reliable branded station rather than a supermarket?)

carknut,
Surprising that nobody mentioned the TB synch hose vacuum caps on the intake manifold bottoms, especially on a 16 year old bike. They can still be in place but severely cracked, which also could happen "all-at-once" during a heat cycle. If there are hoses instead of cap-offs, remove them and cap off the downward pointing brass spigots. A short 1" length of hose with a ball bearing or a gasket sealer coated screw inside the short hose will also work. You should also be able to find the permanent correct size ID caps at an AutoZone/AdvanceAuto/NAPA/O'Reillys franchise. My 2002 50R came with quality rubber caps that never failed in the 7 years I owned it, but some riders on high mileage OilHeads have connected the 2 TB spigots with a length of hose, "helping" to equalize the 2 intake vacuums (essentially the throttle "opening"). That would near perfectly smooth out the idle, especially if the throttle shafts are really worn out and sucking in outside air, at different levels, at every throttle closing.

The symptoms you describe definitely point to a vacuum leak.

The ADV thread was getting testy.

Dunno if carknut is checking here... but his experience following fuel pressure regulator replacement suggests a cause.

"The ADV thread . . . . "
Why . . . . That's Blasphemy!
I did not consider it, even though I have been there. Sometimes the extremely vast audience does not respond at all to newbees as they can be too difficult to deal with. :roll: #-o [-(

Reckon I will always be devoted to our board here, but there's much to be gleaned from ADV as an oilhead guy.

hmmmmm vacuum leaks for me caused it to rev weird, but not die, or I would have mentioned it, here or other site. Wouldn't rule it out though!!! and, as I told him, I bet when he finally figures it out, he'll be angry because its something simple, easily overlooked. just as in the vacuum system....

lol @cyclerob.... Iv'e asked a few questions on multiple sites before.... wide net, much info to sift through, but more GOOD info to glean.
