Glad you got fixed up, but you should know: your bike is still under warranty (less that 3 years old and less than 36,000 miles) so your repair would have been done for free if you brought it to a BMW dealer;
There was no appointments available from any BMW dealer within "Range"
when this happened that could look at the bike that day or even within the next few days. Remember, I was not in my home town and leaving the bike and going home was an option that was a disaster in the making. I did not tell the tech what year the bike was and nether did he ask and I am assuming the BMW tech quoted me for a bike that was done recently was not a warranty repair. Yes, at the time I did not consider it a warranty repair. It was a tragic failure and the thought did not occur to me. My only objective was to get it fixed. Yes, it would have been covered in a warranty situation.
2. no reputable BMW dealer would have replaced anything but the fuel pump if only the fuel pump was damaged;
To further this point, the BMW tech said this pump came from BMW as a "Unit" and would be replaced as a whole, not just the part that actually failed within the unit.
3. Replacement of a fuel pump on. K1600 by a BMW dealer would not have cost $1,500; nor would a dealer have quoted a price for the repair on a bike under warranty that the dealer had not even seen;
When I queried the BMW tech about the problem of course he said it could be a mired of possibilities but he did say "With the symptoms you described it sounds like the fuel pump is inop and that he did one with the same exact symptom last week."
I then asked the appx
cost associated with this repair, (*I had not yet given him the year of my bike.) He said:"Well I just did this repair and the range could be as much as $1500, but the problem has to be diagnosed."
Of course I asked for the "Worst case"
scenario considering my predicament.
4. usually, a BMW dealer who doesn't have a part like a fuel pump in stock can have the part overnight;
The issue was not if he could get the part but I was limited on the distance I could safely ride the bike in that condition and hence that shop could not "Squeeze me in"
until a next week. Yes, my post stated the pump would be "In next week"
and I stand corrected that it was the appointment next week, not the pump.
5. most, if not all BMW dealers would not diagnose a problem like yours over the phone. As a bad fuel pump is not a common problem with K1600s, any number of things could have been the cause of your problem from a clogged fuel filter to a leak in the system, to bad gas (much more likely than a bad fuel pump) to malfunctioning coils, to any of those bad things that you were thinking when you were thinking the worst;
I did simply ask what the problem could be and as stated above: When I queried the BMW tech about the problem of course he said it could be a mired of possibilities but he did say "With the symptoms you described it sounds like the fuel pump is inop"
and that he did one with the same exact symptom last week Now it was me that pressed him for a "Off the record"
diagnose considering my predicament and he obliged knowing my circumstance.
6. that a non BMW dealer had the fuel pump to your bike in stock makes you a very lucky buckaroo. It's unlikely that even a BMW dealer would have the part on the shelf.
Yes, I was fortunate. The part was ordered by the shop and the customer had skipped on the appointment and the part had been there for a while. Lucky, yes, incredible.
7. There is no way for anyone but a lab that can disassemble your pump and conduct sophisticated tests on its various parts to know that your pump failed because of ethanol in the gas.
Modern gas is extremely susceptible to damage fuel component if left untreated in the system. This is a known issue especially for older carburetor bikes. This discussion had been quite involved with an ex Honda guy who was one the development team for one of the "Other"
6 cylinder bike (*Honda CBX) who happens to be the premier rebuilder of only old school carbs, (Welcome to The Motorcycle Project!
) and knows the properties/problems of modern fuels, additives, etc. Yes, he is not an authorized BMW tech and has probably never seen a K1600 but his extreme in-depth knowledge of fuel properties is unquestionable. He explained to me the disruptive nature of modern gas left in any fuel system.
Now, to be fair, this failure would have to be sent to a lab for analysis and then the outcome would have been the same conclusion with a high confidence level that the gas caused the failure. Could it have been FOD? (Foreign object debris) Not at all likely with the sophisticated filter system within the fuel system.
This is a Scientific paper written of the destructive properties of ethanol based fuels:
"Abstract. Generally, ethanol fuel emits less pollutants than gasoline, it is completely renewable product and has the potential to reduce greenhouse gases emission but, at the same time can present a multitude of technical challenges to engine operation conditions including creation of very adverse engine deposits. These deposits increasing fuel consumption and cause higher exhaust emissions as well as poor performance in drivability."
8. It is highly unlikely in any case that your fuel pump would have failed due to ethanol in the gas as there are no parts in it that would have been affected by ethanol. So, please forgive me if I am wrong; but somehow, I'm not buying your story; or as is sometimes said on this forum: I'm calling BS.
The tolerance levels of a fuel pump on this bike are high. There is no "Wiggle room"
for gas that went stale and created a gunk that prevented the pump from operating. Now I was wondering why you would go to such extremes to dispute my post. For reasons unknown your "Expertise"
may have been challenged by my post or perhaps you think I am new to Motorcycles, (*I have 9 bikes, rebuilt 4 from the ground up, been riding for 43 years) and I have been a professional Pilot my entire life and mechanics are not new to me. Of course my Aviation background and the years spent in classrooms discussing fuel and other unrelated mechanics does not qualify me as an expert in the field of modern BMW bikes, but does allow my the ability to comprehend in depth discussions on this subject.
It was not
and frankly what a unwelcome post to a new member here.
