4 cylinder DL650?
« on: December 18, 2015, 09:34:46 »
Looking for some spark plugs on Evilbay using DL650 in the search and it produced lots of hits for packs of 4 spark plugs, I'm sure mine only had 2 the last time I counted  :shrug:

K7 onwards are twin spark plugs per cylinder.
https://en.wikipedia.org/wiki/Suzuki_V-Strom_650 notes the changes though models

Wish I had the extra plugs, only running on one pot at the moment.

Running on one...changing the plug is an obvious choice but I'm sure that there is history of coil failure too. My memory is a bit rusty, so no guarantees but just try swapping the plugs between cylinders and see if the problem moves with it.

Found a couple of new plugs I'd bought a while ago. Thanks for the info about the coils, going to start stripping bodywork off this afternoon and dust off the test gear  :)

One more possible cause of running on one cylinder is corrosion in the crimp connection that feeds power to the fuel injectors. Each has a yellow/red wire that should be live when the ignition is on. If one is dead, it can be jumpered to the Y/R wire from the ECU to bring it back to life.

Thanks for the injector wiring info GW

Well it took some ingenuity to get the front plug out  :)  both plugs were a bit sooty (may be due to low rpms urban commute?) and gapped OK, they were fitted 5k miles/2.5 years ago.

Tested coils, both OK so fitted new plugs and of course it ran fine, I hate not finding a definite fault as the next time I might not be at home when it fails.

Just got to adjust the clutch and put the bodywork back on.
