Why have you not bought them yet?

I've approached both sellers about buying now, but both want to let their auctions run.

Therefore I am currently winning both auctions.

Seems that fate likes appearing at opportune times

2 CBR600RR heads have appeared on ebay, both have been flowed and ported and both have the kit cams in.


Hmmmmm......shall I ? 

I'd want to know, who, where, when and how much work they've done ....

I stripped the bike down over this weekend, got the engine out, then stripped the top end down and took the head off.


These are the results


Top of block


Underside of head with gasket


Top of block with gasket popped on



What d'ya reckon ?

Water is being consumed throughout a day

A friend with an 05 RR has similar overheating and coolant loss symptoms. We could not find any evidence of leaks anywhere, engine hot/cold/stopped/running, so my friend decided head gasket - removed the engine to get it rebuilt. The engine builder told him that there was nothing wrong with the head gasket, but diagnosed a faulty radiator cap that could not keep the coolant under pressure.

I would suggest whatever you end up doing, replace the rad cap too for the sake of £15.

Rad & cap have both been replaced already

Nothing is jumping out at me. There is the possibility that you may have a porous component in the mix.

Looking at left hand cylinder something going on as it looks washed the carbon has been washed away it is even on other 3 cylinders
if you have air bubbles coming up to the header tank all the time when it is running does point to head gasket what does the gasket look like ? it has been apart for a while now might have a rust line some where showing the leak ?
