engine noise

999sime · 25-Mar-2005, 22:47

Just got home by RAC recovery after 3hr wait. First good ride of the year came to a halt 30 miles from home. After a quick blast up a hill eased of, went to accelerate again no power just horrible noises from engine.
Has anyone out there had any terminal engine problems with their 749/999?.

Cam belt snapped?

I don't think anyone on this board has had a terminal failure of a 749/999.

I've heard of belt failures on the 748/9** range. How old is your bike? Any recent mods to the engine?

Can you describe the noises?

No belts are ok. due to be changed in 2 weeks though, Sounds more like bottom end.

Flywheel nut come loose? That can happen from time to time. How many miles on the bike?

The bike is 2 years old. no engine mods, the noise is a loud clanking just of tickover, which you feel right through the bike. It does still start ok though.

8700 miles.

I wouldnt be running it if it sounds that bad

It could be the flywheel. If the bikes in your possesion you could emove the left hand fairing panel and the flywheel cover but only if you know what you are looking for.

If the flywheel has come loose then you will feel vibration through the bike. It's not a good idea to start it as this can strip the splines off the flywheel end of the crankshaft.

Loud enough to drown out the open clutch!!. Still soon find out what it is when i stick it in the back of the van and take it to the dealers.
