hi ,
I have an issue on my 2010 DL650 , its started to run poorly ,mainly miss fire and loss of power . so I tried to go for a run out 4 weeks ago , bike starts and ticks over , headed out and within 300 yards power loss and miss fire happens , pulled over and bike stalls , reluctant to start up again easily but managed to start and limp home going in and out of the miss fire issue and running OK . once sat a while ,bikes does the same , starts up and idles OK , revs and sounds smooth , turn off ,restart and sometimes it sounds terrible and obvious miss fire on front cyclinder.
turn off , restart and its OK again , but everytime I try and ride ,the original problem happens.
things I've done so far
replaced plugs
checked primary and secondary coil readings ( OK)
adjusted valve clearances (a little out so re shimed to tolerance )
replaced air filter
checked fuel tank for debris /rust ( all clear ,clean tank )
removed injectors , checked over cleaned and replaced , measured resistance and checked for voltage supply from ecu ( all OK )
no fault codes on dash , even borrowed a obd reader on laptop , no faults while engine running , can't see any issues on the live data .
its driving me crazy , any ideas would be appreciated , many thanks chris
