Hi All

Just in the process off fitting an Oil cooler to my Fireblade BEC and I wondered what the difference was between a standard duty Mocal Unit and a Heavy Duty unit.

Will the standard dut unit do the job, or should I go heavy duty?

Cheers

I don’t like the description standard and heavy duty, in oil cooler terms it’s about the area of the cooler.
Width and rows, I.e. 300mm x 13 row.
If your running a bike engine then the one that came with the bike is a good start.
Ducting cold air through the cooler increases the performance, letting the hot air out of the engine bay is essential.
Go for s known make Mocal or Setrab, use an oil thermostat.
Look at cooling as a whole, water, oil, heat in the engine bay, wrapping exhausts, heat shielding, letting the hot engine bay air out faster than it cane in.

I was told me a couple of years ago the standard Mocal ones are made in the far east (China?) and the HD ones are made in GB (or EU).

Adding to my earlier post
I had a braided hose clamped with jubilee clips blow off luckily I shut off and saved the engine, the replacement hoses wher swaged on black hydraulic hoses with appropriate threaded ends to fit oil cooler and thermostatic takeoff plate.
