Hard right or left plus bump would make me think about a fault within the wiring harness as it is zip tied around steering. Big history of too tight zip ties breaking wires.

Mr. Towerworker,

Lose wirings' issue came to mind/why when sputtering happened after sharp turns. I rechecked wirings again, checked good.

When bike sputtered two days ago, I have minimum fuel in tank, No warning light yet

Is it possible that no fuel to pump momentarily after I leaned hard left or right?

I filled the tank up today and rode for an hour, Hard!!! No Sputtering.

Could this (sputtering) caused by combination of Bad Coil and Fuel Pump/Fuel Issue?

1. Bad coil is the primary cause of hiccups when it got hot, unable to put out more juice to plugs. As I mentioned, bike will run ok (coil cool down) after I stopped riding 10-20 minutes.
2. Low fuel in tank caused pump to suck in dirt or got hot plus momentarily no fuel to pump and hiccups occurred.

I will have to wait after I did some serious riding for a few days.


thank you, sir for your suggestions

Re: 2002 R1150R Sputtering fixed Coil Issue

Post by gaijin »

After 2 1/2 days of riding hard, I believed the problem of sputtering when bike got hot, Solved. Replaced bad coil and bad spark plug wires (one of the wires has cracked/broken near cylinder head).

Will continue to find another problem, hit bump and left/right lean made bike sputtering.

That sure sounds like a wiring (electrical) problem not fuel. Something grounding out! Look at the front loom that leads to the HES.

With motor running and bike in neutral, you could experiment with the "sharp turn" effect:

1. Keep bike vertical and turn handlebar back and forth through full arc;

2. Keep handlebar fixed in center position, and lean bike over from side to side (best with some help).

Results of experiments might reveal cause of the sputtering.

Sweatmark,

Unable to duplicate the causes of sputtering by lean the bike side to side or full turn to left or right. Bike ran normal.
I even checked all wirings under steering column for free movement or binding, also, ground wire to starter. All checked good.

I took the bike out for 30 miles ride, ran good even turn hard left or right.

Just close to get home, did the right turn. Bike sputtered mini-second and go back to normal.

Will check and recheck again


thanks

If me, I would pull every plug including the big one to the ecu and clean and look for corrosion. Your in a wet climate. Corrosion is hard to see sometimes. I use "Deoxit" on all my stuff including aircraft.

^ that reminded me...my 1976 Honda CB 360 would occasionally 'sputter' and I couldn't for the life of me figure out why. I'm only marginally mechanical so beyond checking the basics of fuel/compression/spark I was at a little bit of a loss. One day I was poking around with the 16 pin connection on the main harness and jiggled it with the bike running. Sure enough, what ever was being interrupted caused the bike to cut out momentarily. Even taking the plug apart everything appeared clean until I dug a little further to find corrosion at the very bottom of the connection on the pins. Seems that the battery overflow was missing the hose to drain to the ground and instead whatever weeps out of a battery was dripping on this connection and probably had for years. Ordered a new connector and terminal ends and when they were all replaced never had the problem again.

I can't offer any assistance other than to echo Kirby's recommendation to double check all of the plug connections since other elements seem to have been ruled out. My Honda experience is probably as far away from a BMW as possible so I'm only relaying this story to say that sometimes it's the simplest of things that might create a problem. Best of luck-

Re: 2002 R1150R Sputtering More Question

Post by gaijin »

I rechecked the free movement on wire harnesses, repaired anything that looked bad included pulled the wirings while bike is running. Still unable to duplicate the sputtering when turned hard left/right. I will leave HES alone for now and focus on fuel pump.

After I read several symptoms of bad pump which I refused to consider that I might have bad pump. Here are the reasons.
1. Bike ran at accelerated speed, 50 mph (80 kmh) which it is my average speed in Japan for me. Bike has started to sputtering/jerky and resume normal.
2. Poor gas mileage, I am normally see Yellow Warning Light about 270 kms; Now it is about 230 kms and jerky started but all the time.
3. Heat issues, I used to mentioned about sputtering when bike got hot. I assumed that could be HES and Coil issue. Bad coil and spark plug wires. Solved. Bad pump created heat to engine, lack of fuel. After stopped riding 20-30 minutes, bike ran normal.

I will take a chance by replacing fuel pump; I considered as due to be replaced at 99,000 kms. I found a fuel pump for $99, not whole assembly at euromotoelectrics.com

Will find out, soon.

I have installed a new fuel pump, checked on wire harness again, cleaned the connectors, turned left/right and looked for binding etc.

I took the bike out on a short ride and hope to duplicate the sputtering, Not Happened yet. Since it was a short ride no more than 80 kms, I will have to wait and see, keep my fingers crossed.

Minor changes after replaced old fuel pump.
Bike still sputtered after leaned and turned left/right, 45 degrees
- Less frequent after leaned and turned included from dead stop.
- Less Jerky or violent than before.
- Shorter time of sputtering.

Will continue to search on this problem.

temperature is in mid-50 F; bike ran ok on 30 - 40 miles. Not sputtering.

Will do more riding tomorrow before snow or too cold to ride.

Re: 2002 R1150R Sputtering Fixed??

Post by gaijin »

Folks,

Honestly, I do not know that I fixed it (Stop Sputtering); I will not find out until next Spring when temperature get warmer.

I rode about 150 miles last week, up and down the mountain, twisted/turned, duplicated the turns/leans. No Sputtering.

Is the temperature has anything to do with it?

It is cold this time of year in Northern Japan, 10C and dropping.

Replacing parts:

Ignition coil, Spark plug wires, Fuel pump and Filter.

14C, took my bike out for a short ride.
Bike ran good, No acting up (sputtering) yet.

I will find out more in 2-3 weeks when riding season start in Northern Japan.

I am hoping that sputtering will not occur again.

Took my bike out for 200 kms check-up.

No Problem. I had several issues with this sputtering; it is so frustrating.

If it happened again, I will forget about it and ride easy.

IAW. New Owner
Bike misfired at all ranges two weeks ago when outside temperature was around 28C - 35C
He was stuck in heavy traffic etc.
After bike cool down, it has no issue at all.
He rode the heck out the bike, seen him everywhere in town.

Yes, I decided to rid off the bike; I am getting too old.
I bought a small car with good gas mileage, to go places.

Sorry to see you off the bike! :(

I hope you decide to get another at some point. :)

With the spluttering - I was going to ask if it happened when the bike was leant over ONLY, or if it happened when the steering was turned?
IE - is the effect caused by steering movement, or by angle of lean?

I once had a very, VERY weird issue with a ZR550Zephyr - it would cut out ONLY when the bike was leant over to (if I remember correctly) the right, and ONLY when it had been raining the day BEFORE. Drove me insane for about 3 weeks (commuting 40 miles each day into London - so mostly motorway and straight roads - the bike was 'usable').

EVENTUALLY I traced it to the fact that:
a) the main ignition control box was tucked into a plastic box under the seat
b) the wires for that control box entered into it on the underside
c) the drain plug in the plastic box was 'partially' blocked.

So - the plastic box would fill with water - MOST of which would drain out, but SOME would be retained...... JUST enough to short out a couple of the wires in the connector block that fed wires into the control box! I eventually figured it out while riding down the A40 one morning (after spending 3 weeks searching the wiring for faults every damn night), so I pulled over, ripped the seat off, discovered the box was sloshing with water, and (lacking a pin) I pulled the control box out and turned it over, so the wires weren't in the water. PROBLEM SOLVED! :D

Some issues are just weird...

I thought your issue MIGHT be water trapped in one of the electrical boxes somehow.
