21-3-2015 - 1125 engine noise, time to take action.
i have been starting and listening for engine noise on this bike for some time now, but it is very difficult to pin point even if you hear some something ( most off the time i hear nothing ) .. checking the basics... coolent empty.
1125 engine noise , will refill the radiator also.
1125 engine noise, oil drain looks not really nice... and lumpy ? i wonder if this is still the first oil ?
1125 engine noise , some metal on the drain plug, but as the engine is still very new ( only 2700 km ) there can be some debris on the plug as the oil also lubricate the gearbox.
1125 engine noise , oil siff cover also some debris.
1125 engine noise , flacky stuff not really much
1125 engine noise , cleaned the siff and put it back as i will take off the clutch cover to check the water pump / oil pump.
1125 engine noise , with a c-clip in the clutch cylinder this will prevent the cylinder to pop out,
other 1125 noise for diagnose..this one is clear as it sounds just like a ducatie running in neutral , when you pull the clutch the sound is less / gone. so clutch out to check the mainshaft nut holding the hub.

1125 clutch noise, with a lucky grab you pull out all the plates in one time, best to stack some back to loosen the clutch hub nut , or make a locking plate from some old clutch plates.
1125 clutch noise , the problem i thought it was, a loose hub nut, was not it , there is to much play on the transmission dampening , these springs should be tight , but i can stick a screw driver inbetween with out problem.
