Hi I bought a cbr600 black frame 2001 model was used as a race bike from day one now it runs total loss ie no charging system and no fan no coolaint bottle just a overflow bottle now I want to add a water bottle but can't find were the top hose goes coming down to the bike I have my overflow hose in the bottle but were does the other one go and how far should my radiator be topped up to help please

 

You can download a Service Manual (very helpful): LINK. On the F4i, there is a nipple on the side of the filler neck on your radiator to which the coolant reservoir hose attaches to. The hose should be routed on the right side of the engine. As for the radiator fluid level, it should be filled to the brim. Run the bike to operating temperature with the radiator cap off, and keep filling as needed (it'll suck it down as it warms up). Once satisfied with it, put the cap back on and fill the reservoir to the recommended level.

 

thanks for that ok now without having the bottle installed just now what should the radiator be filled to as the cooliant bottle is not fitted yet just running the coolidnt in the radaitor

 

All the way to the top ... and I would attach the coolant overflow hose to the radiator lest it sprays stinky coolant all over your engine. Also be careful about getting it on your rear tire. But technically, you shouldn't be riding without the reservoir hooked up, imo. I'd wait until you attach it to ride it.

 

Thanks for the much needed help
