Hello everybody, I am currently in process of converting a ZX6R 95-97 to a street bike (big handlebars, naked)

I am going to replace the oil radiator with a under filter heat exchanger found in the 98+ models, this brings up a question whether I should blank off the oil lines from sump to the oil radiator or fit a loop to keep this passage open

I have researched the web and on ZXR400 forums there has been a somewhat non-conclusive discussion regarding this matter, where some members have had it just blanked off, claimed they raced this way and it not made a difference, some say that is what they think killed the motor

I have yet to review the haynes manual which I have for this model, but not sure if there are oil flow diagrams there.

The main idea is, in order to run a semi-reliable setup, I want to replace the radiator with newer model, after-market radiator, so that I can get rid of the oil cooler that is now perishing (fins brake away they are rotten) and run a new, larger radiator and utilise the heat exchanger. It seems to make more sense money wise to run such setup as opposed to sourcing two new radiators (£80 vs £350 for coolant, oil radiators that would perhaps fit, £80 ish)

I already sourced a radiator for £80, have the heat exchanger from an engine I took apart, £10 for the heat exchanger bolt, will need a coolant tee, £16.50 for a 98-02 radiator fan and thermoswitch. If I manage to sell my old radiator I will be having a very cheap upgrade and will not have to run 24 year old rad...

I can also confirm that 98-02 models have the same sump, with the oil connections there but they are not drilled and tapped and are not used.

So, would you loop or blank?

loop or blank, either way.......you'll be "cooling" with the rad liquid anyway...............I'd blank it.
