K1600 Cylinder firing Order

<< < (3/4) > >>

GS Jim:
Just curious, what brand/number were the plugs?

e7navy1999:
NGK Spark Plug LMAR8AI-8 set to .032 gap,  Just had one plug over a decade that was bad.  It only misfired when it was a engine temps

GS Jim:
Yea bad luck, out of the litteraly hundreds of ngk plugs I've bought over the decades I have never had a failure.

e7navy1999:
Me2.  This was the first bad plug ever 4me.  It only became intermittently bad after running engine temp was reached.  I first swapped out the coil and the fault was still there so then I ordered in a new plug and walla..runs like BMW is supposed too.  So far no engine light and fuel economy is back to 43/44mpg

botus:
this is not correct

Cylinder #1 coil fires 1
Cylinder #2 coil fires 5
Cylinder #3 coil fires 3
Cylinder #4 coil fires 6  GS911 reads "coil #4 is the 6th in firing order"
Cylinder #5 coil fires 2
Cylinder #6 coil fires 4

GS Jim has it right in his post

--- Code: ---Don't know if this helps but the BMW RSD says to check valve clearance by setting TDC in order of 1,5,3,6,2,4 and numbers the cylinders 1-6 L-R facing forward.
--- End code ---

going down the list below is the engines firing order

Cyl #1 with coil 1 goes pop (thus if the bike happens under cranking to get compression on cyl 1 would be the first to go pop)
Cyl #5 with coil 5 goes pop next
Cyl #3 with coil 3 goes pop next
Cyl #6 with coil 6 goes pop next
Cyl #2 with coil 2 goes pop next
Cyl #4 with coil 4 goes pop next   AKA - "coil #4 is the 6th in firing order"
