My 2004 R1150R (50,170 miles) suddenly developed a cold hard starting starting issue. It takes a lot of cranking and various faffing around to eventually get it to fire up. Once it is warmed up though it starts like it used to - almost immediately on pressing the start button.
- There are no other issues with the bike and it doesnt seem like ive lost any power. I'm not a real aggressive rider though so not sure if I would notice a subtle drop in power.
- This issue came on suddenly - a day after I changed the oil and washed it last weekend. However I rode it immediately after the oil change and it fired up fine.
I have done the following:
1. Checked the Battery. Battery is ~2months old. When fully charged (engine off) it reads 13.3VDC measured at the battery terminals. When I turn on the ignition it reads
12.2VDC. When I start cranking it goes to 10.3VDC. I think this is normal right?
2. I checked for spark on the upper plugs (i have a dual spark engine). There is no spark on the right cylinder and a faint spark on the left cylinder. I swapped the coils between left and right and the faint spark/ No spark followed the coils.
I suspect the stick coils after test #2. Before I pull the trigger on new coils I would like to make sure. My buddy has an '03 1150GS (single spark). Does anyone know if single spark stick coils would work on my dual spark bike to do a quick test?
BTW the Part number for the coil on my bike is 7 671 896-01
Thanks
