camchain tensioner

(1/9) > >>

bigmockuk:
ive had to take the head of my 550 k3 3 times to find out what the loud tapping sound was,it sounded like a very loose tappet even tho i knew they were all set,bike was misfiring on no 2 so while i had the head off i removed the valve springs thinking one had broken but all was good,so after i took out the camchain tensioner i saw what the issue was,about an inch n a half up from the bottom (facing towards back of engine) something has been hitting against it,so i thought maybe it had came out of place since i had did about 100 miles since barrel was last off,so i put it all back together and noise was still there  >:( so pulled it apart again and put a slight bend where the shiny groove was from whatever could be hitting it,built it up and hoped it would be ok but its not,its not as loud but still there,any one any ideas as to what could be hitting against the bottom of the tensioner?

SteveW:
Is the bottom end of the tensioner sitting properly in its groove in the case?

Very easy to fit it without it sitting in the correct place.

DomP:
Do you have any photos of the tensioner?

Seabeowner:
The bottom of the tensioner sits in a pocket in the crankcase. Best to remove the sump and check that it is correctly inserted.

i dont have pics which is totally unlike me i take pics of everything i work on,my next question has just been answered,can the tensioner be seen from below when sump pan is removed? so thats my next job,if its half dry tomorrow i`ll get the pan off,take some pics n hopefully find a solution,so i`ll upload pics of what i find,cheers guys
