Had a chain bust on me many years ago. Bunched itself up in front of the front sprocket and punched a hole into the gearbox.

Fortunately it was brand new (just a week old). Initially D.I.D. inidcated that I may have fitted it incorrectly. Once I explained my engineering background (they didn't ask for proof) they agreed that it was probably ok and quickly provided not only a new chain, but also paid up for new crankcases, roadside recovery etc etc. Good on D.I.D.

Mentioned to a Mille owning mate of mine that I used WD40 to clean my chain and he said there was a thread on the RSVR net that reckons this is a bad choice of cleaner as it removes all the good grease etc from the X/O rings due to its penetrative properties, anybody with more engineering savvy than me have any thoughts?

[Pete A]

That's right, WD40 can affect some O rings, as it's made up of petrol distillates, amongst other stuff, and can cause them to swell. We recently had problems with some components at work, and I spoke to the technical guys at WD's head office and our O ring supplier, the consensus was to either change the O ring material to Viton (the green coloured ones used in carbs. etc.) or use a silicone based lubricant instead.

Surely it takes a lot to snap a chain??

I've never had one go (yet!!!) and I'm generally quite slack when it comes to looking after the chain. It tends to be when it gets shiney that I think "hmm better put some lube on that".

Never ever cleaned one though, just slap more lube on.
