Hello everyone%

I have 2005 C90 and for a past 4 months I have bin in a shop 2 times% and and still can't figure it out what's wrong with my ride. What is happening is runing poorly and misfiring rear cylinder, while driving bike is jerking and hesitating, just running bad. I have to replace rear cylinder fuel injector twice because of that. Something is causing the rear cylinder fuel injector to fail. Coils are good I have switched them to see if will transfer the problem to the front cylinder but NO. So they must be good.%

Guy's do you have any problems like mine ride?

Help me to find the cause. I love this bike.

Thank you

Doed this have a coil pack system or cables and separate coils. If its the latter did you chck the cap and cable also have you checked the plugs. Could it be fuel related if you have definatly discounted the electrics side?

Any other symptoms.....or details that you forgot to mention ??
Like maybe it only does that when HOT.....or cold ?

I think you need to find a different shop and have a complete engine inspection done, including compression and leak down tests.
Could be an intake manifold vacuum leak or a head gasket leak.....or a lot of other things.
Apparently it is NOT simply a bad injector.
