Only hitting on one

[spyderspyke]

I have a 2010 RS and the other day I started my bike and it was only hitting on one cylinder so I thought it was ether plugs or wires so I changed them but still the same thing any thoughts?

Did you check the spark? Sounds like you make have a breakdown in the coil?

 

[spyderspyke]

no it has no spark to the back cylinder

Then you have a problem further up the line from wires and plugs.

I already knew that but what else

Coils....

Only thing left is the coil or the power to the coil. After that you have the electronic ignition...:dontknow: if you have or can get a shop manual (on line $20.00) it will show you the steps to track it down...

no fire

my 09 did that and wound up having to replace the plugs and wires
