Lost Coolant 2000 mille

Afternoon all,

Just had a short ride home from work and as i was removing my helmet i spotted a puddle forming under the bike.

The coolant tank is almost empty and with the fairings off i can see spray all over the front of the engine.

It seems to be coming from high on the left side but i think i may need the tank off to investigate further.

Are there and common locations for water leaks that i should check, or any other pitfalls i should be aware of before removing the tank?

Thanks
Rumple
 
could be one of the rads I guess.
Fill her back up and run up to temp or untill you see it squirting out.
Try not to get burnt!!
 
There is a weep hole on the right hand side of the bike just below the starter motor (its actually the water pump) that when the seals go can blow water although more usually oil.

Thanks, though from what I can see it appears to be leaking from high on the left side.

I have been looking through a copy of the RSV repair manual, has a chapter on "cooling" and shows the routing of all the cooling pipework.

Given the rate the fluid was coming out I think it should not be too hard to spot the offending item.

Kinda bugging me that I cant get out of work today and have a look and maybe get some parts ordered.

Managed to get out of work early and have a look at the bike.
The was a small hole worn in the back of the left manifold/radiator pipe. The ose was rubbing aagains one of the engine fasteners
The angle of the hole caused the spray to aim upward then the fluid was dripping of the bottom of the fuel tank.... hell of a mess

its part 6 in this image if anyone encounters a similar problem, and its bloody hard to spot even with the engine running.
 
Thats a new and interesting one...glad you found it, but i guess the question has to be asked why it happened at all ?

Its a good point and I have assessed why the damage occurred, which is because the pipe was making contact with the engine.
Rotating the pipe you can drastically reduce the possibility of chafing but due to the routing of the pipe I cant say with 100% confidence that some contact will not occur when the engine is in use.

The 2 areas where the pipe is closest to engine parts i will apply some Teflon tape, which will greatly increase the pipes resistance to wear.

New pipe cost £22 with tax and delivery, i'd say I got off pretty light with a cheap part and a few hours of my time.
 
Ive checked my pipework (2000 model like yours) and mine come no where near anything and certainly not any engines related fasteners.
 
Thanks for the responses kiwi, here are a couple of pics showing how my pipe was fitted.
There is very little space for the pipe to fit between the fasteners and the oil tank is once refitted.

Does yours look different?

An unfortunate side effect of the engine being sprayed with coolant, it has become a dirt magnet.
I was planning to do some jovial cleaning this weekend, but as per your suggestion I will ensure that I am serious during the cleaning process :)
 
Conducted some dour faced engine cleaning over the weekend ;) and today the replacement pipe arrived.

Bit of a bugger to fit the top clip where it connects to the 3 way manifold.

The old pipe is about 1" shorter than the new one which explains why its route was so close to the engine, it also lacks the reinforcing fibres in the rubber!
Perhaps the design of the pipe changed since my bike was built (W reg)
 
just raised the tank on its hinge and left the airbox on, the access is not as bad as it looks.
