It seems like my rear cylinder does not run. Iv'e seen others have had this issue (some with front) but they never come back and post what the issue was.
New to me bike. prev owner could not get running thought it had bad injector
they had hacked the wire harness pretty bad so I replaced that
I get a c28 code for the stva so for now I removed the secondary throttle blades
The injector prev owner assumed was bad tested fine but they had butchered the nozzle so I replaced it (tested it for click and flow)
had c codes for the 2 Iap sensors due to missing vacuum lines (replaced those)
bike will now start and run
Front exhaust temp is around 330 rear around 110 (pipe not shields)
Have spark on all 4 (old plugs was black so went ahead and replaced them)
sometimes when starting it will burp out the intake
pulled covers and checked cam timing front and rear, looks fine
Only other thing I can think of is ecu....
do these bikes have ecu issues? maybe not activating injector or leaving it stuck on?
anyone else ran into this?
