Hi,
Took the fazer for its first proper ride out the other day.
Went to snake pass, and despite my slow a55 riding, I enjoyed myself - the renthal low bars worked very nice (except being a bit vibey sending my fingers to sleep - balance carbs?)
Anyway, I must have done 150 miles over the day, but on the last 10 miles the bikes started making a horrible "DUNK", or "CLUNK DUN" every few seconds from the drive chain area.
I nursed it home very gingerly as the whole bike seemed to stutter and lurch as it did it.
I had a look today, assuming the front sprocket had worked its way off (heard this is common issue) - but the sprocket is fine - thought it might be the chain, so I adjusted and oiled it - that was fine too with no lumpy issues when rolling the rear wheel on the centre stand.
So next I banged it into gear and THERE it was, every few seconds the chain jumped - it looked as if the front sprocket was locking for a micro second every few revolutions, same through the gears...however
it DOESN'T happen if I pulled the clutch, I could pull the clutch in and it would carry on spinning nicely, so dramas, and then as soon as I let it out it would come back.
So I think it is something to do with the clutch (I guess ti wont be gearbox if it happens in all the gears..)
Anyway, before I whip the side case off and strip the clutch, any bright ideas about what it might be?
The bike has 50k miles on it, and not very pretty - but not had any issues till this (I commuted on it daily last year for a month or so, and did one track day session the other week when the local track let newbs have one 20 min go for £10!)
Thanks
