Take off your front sprocket cover.

G'wan g'wan, g'wan....:D

All you need's a 5mm allen key (or socket).
Undo the two screws, unhook the cover from behind the clutch slave cylinder, lift it away, and have a look.

Is it filthy? Full of a foul mix of mud and chain lube? :o
Or is it spotless, because you clean around here all the time?
:saint:

If it's filthy, clean it out properly, and examine the sprocket retaining plate.
Is it in good condition, and are the 2 small allen screws correctly tightened?
And what about the sprocket itself? Teeth hooked and/or worn?

Front sprockets have to transmit the power of the engine through a very small number of teeth: they have a hard life.
Keep an eye on them.

















As you've probably realised, I'm only posting this cos I took mine off yesterday for the first time in ...... let's just say, a while, shall we? :lol:

I daresay many of youse guys check here regularly anyway. But if you don't, it's not a bad idea to do so regularly. Those sprocket retaining plates can fail, y'know...

You have no idea how much filth I found around my 750's front sprocket a couple of months ago - better for everyone that you never know.

The horror ... the horror ...

:o

Hmmm, spent some quality time over the weekend cleaning and lubing, never thought to look behind there though. I think I'd better go and check it out - good advice.

Ade.

If you ever wondered where all that chain lube goes that doesn't make it onto the back wheel, but disappears from the chain, look no further.

The chain damper pad on the swinging arm is another good hiding place, as is under the chain guard.

Sticky or what :o

Look for witness marks on the plastic cover to see if the sprocket retaining plate has failed allowing the sprocket to move along the shaft and rub on the guard. There was a recall about this but i think it was only on the ST series?
