How bad is this?

[jaxx]

Ill save us all a lot of hassle, and cut a long story short...

Whilst riding to a training session earlier, the chain became loose on my gsxr750.

Then the back wheel locked...

It then freed up

and the chain trashed everything it came into contact with...

Basically, its smashed something containing coolant, just behind the clutch adjustment cover on the engine.
What is this? Is it the pump housing? Are they mega-bucks? Is it fubar'd? Should I keep , or just

Thanks in advance for any help
accordingly...

Cheers,
Jack

That's the place the expansion bottle will typically go.
It's not mega-essential, but worth replacing.

When the radiator gets too hot, it will vent into there - as it cools it sucks it back into the radiator.
Often taken off on race bikes and the like.

Ok, sounds good...

Just for my own piece of mind, is that normally made out or a metallic material?
Because there was a big old shard of metal in the bottom of the fairing when I stopped...

Hopefully thats all it'll be, or something equally minimal...

Cheers G

Usually plastic - however there's likely to be bits of metal around.

Might be best if you could get some pics.

[jaxx]

My plan is to get the fairing off 1st thing tomorrow, then have a proper survey of the damage...

Ill keep you posted, possibly with pics...

Cheers for the tips, gives me somewhere to start...

Did your chain actually snap or come off? You need to remove the front sprocket cover really and make sure it hasn't cracked the crankcase anywhere (the main 'shell' of the engine). That lump of metal must've broken off somewhere so find it. You might be lucky and it's just part of the sprocket cover or something else that can be replaced, not always that lucky.

[prawny1]

It's unusual for a chain to suddenly become loose, if you have damage around the front sprocket area i'd say the sprocket has come adrift or the teeth have sheared maybe output shaft or rear wheel bearing collapsed even.

If your lucky the metal will be just part of the sprocket cover, if not it could be part of the crankcase.

Ok, Cheers for the tips guys, always nice to know where to start....
It is now the morning after, and I am feelin a little calmer about the whole situation.

A friend/neighbour has offered to lend me a bike of theirs to use until I get my baby fixed/evaluate the damage...

Im just headin outside to start stripping the fairing etc...

Expect updates,

Cheers

Meant to say before, the chain broke.

The fairing is off, i've stripped it down to the damaged parts

The sprocket cover has taken the brunt of it, but is just about still usable, only one fitting point sheared off.

The part thats confusing me is the part that was holding a lot of coolant, its not the reserve tank I dont think, as tis is mounted by the fairing. Its round, and appears to bolt on to the engine, directly infront of the front sprocket.

All in all, pretty repairable I would say at this point, but we shall see.

Next job is to take the unidentified damaged part off, and head to my local garage, to find out A) What is it, B) How much is it & C) How soon can they get me one!!!

Cheers
Jack

Post some pics up so we can try and identify it?

[nightshaddow]

theirs allot of knowledgeable guys here, and there not in it for profit, always get a couple of opinions if the bike is not going to the garage, they might get confused lol

pics are always handy

Whoop! Parts Identified!

They are, The Water Pump Housing, Obliterated, but the mountings are ok-ish...

&

Front Sprocket cover, Badly Damaged - will replace if I can find one for the right price.

So, to summarise, the parts I need are
New Chain
New Sprockets
New Pump Housing
New Sprocket cover

Im gonna have a look about for prices now, what would you expect to pay for that little lot?

Cheers again all

[G]

New Chain New Sprockets - £100 or so for a set, maybe a little more.
New Pump Housing - maybe £25 or so, depends on the year of the bike and how lucky you are, on the second hand market.
New Sprocket cover - you don't NEED a sprocket cover, again £10 or so, depending on the second hand market (racers often don't use them, so worth looking that way.

This thread needs pictures!

Well, thanks for all the input, its been most appreciated.

I've got the chain and sprockets, cost £120 for the kit.
I've had no luck sourcing the new parts, other than new, and thats gonna cost...

Also, just realised that the clutch push rod was sheared too, will need replacing.

Have looked into it, and the part I was calling the sprocket cover encorporates the clutch adjuster, so is an unfortunate nessescity.

Am waiting on a few places, so when I hear, I will let you know.

Also, Im working on the pics, if only to whore the damage , but my camera has decided to freak out. Would buy a new one normally, but im afraid fixing the bike will cost everything I have...

Will try and borrow a friends...

Ps. The FZX750 I have been loaned is a winner! Cheers Paul!

Cheers,
Jack

Uhhm why exactly did the chain snap tho?
poor maintainance? way pasts its replacement mileage? no lubrication?

Wasnt ment as a jibe just a reminder that neglecting that kind of thing could have turned out much worse, have seen pics of chains slapping peoples legs after snapping and causing some nice damage.
