So i did sort the problem out turns out the wood ruff key was damaged on the fly wheel side and was causing bad timing that was causing it to back fire and in turn blow the seals out
all repaired now and running as it should
thanks all
Hi
Thanks for the reply. Seals was tight there was a grove in the bushing but seal didn’t sit on this so I cant see that being an issue, bearing was good and didn’t see any play in the crank.
Iv now turned the bushing down 2mm as couldn’t find a replacement and fitted a 36.52.8 from a ktm...
Hi everyone
Ok so I recently bought a 2006 ec 300 the bike did run relatively good, so after a few rides I decided to change the oil, when I drained it only 600ml
Came out so i replaced it with 900ml and it started smoking really bad and burning oil.
I?m guessing the crank seal was already...
