Hate to be sitting here typing this out especially when i've literally bent over back wards to look after my pride and joy like most, Anyway noticed an issue after a recent incident due my lack of judgement. Otherwise Bike was running perfect before storage and after. Let some one see my bike and they revved the engine really high and i noticed this rattling sound after..
Changed to full synthetic Motul oil around 7 months ago, Everything else was working fine no issues, starts up perfectly. 4T 7100 10w 40.
So many threads appearing with similar issues. Have narrowed it down and just need you help to confirm please. Full details are above which hopefully will help us pin point
CCT- Some point to the CCT which i'm hoping it is. CCT can get got thrown of balance due to the sudden
high to low rpm
rod bearings - Can cause damage to the engine and is the last thing a bike needs. Apparently the main
cause is when beginners take the rpm to high and not moving. If it's this i'm screwed :)
Or hopefully just a loose nut. Have added some video with similar sounds
video below - Cold start, idle
Almost sounds like a timing belt issue on car. So have decided not to ride till it's sorted anyway. Only riden 3-4 times since, not very hard at all, urban areas not much on highways
Hopefully nothing not a problem, let me know what you guys think please
Thanks again, take care
