3AJ oil cooler relocation?

Post by keny72 » Fri Mar 16, 2018 8:13 pm

So I wonder if anyone has relocated the oil cooler on a 3AJ? (or 1VJ for that matter)
I been looking at colors old Dakar Teneres has used, and noticed the 86 XT600 Dakar bike has the oil cooler under the headlight

Ok, it don´t have the twin headlight of the the 3AJ, but I started to think if, for example a Honda VFR750 -86-89 oil cooler could be fit hanging below the front faring.... :book:
Image
And is it big enough? :fireball:

Toughts are welcome
:tenere:

Which oil cooler are you talking about? the short one on the MK1 3AJ or the longer one on the MK2? (1990) and do you need to relocate it? the one in the picture is not a Yamaha item (on the bike).

One member on here was playing with the idea of a cooler from a Citroen 2CV, but i dont think its necessary, you could put two of the longer 3AJ items side by side if you welded lugs to the frame.

You can buy generic OIL COOLERS any size you want.

What are the respective length of my 1 and Mk2 3AJ oil coolers. Think my bike is a Mk1 but seems to have a long cooler on it.

Interestingly I noticed that the DT125R Tenere (2 stroke) has a fairing very similar to that on the 86 works XT600! Maybe it would fit!

Would it be possible to mount it to the front frame down tube, this is the location used on the old BMW gs bikes and it works well, obviously a need to fabricate a bracket for that job on an XT but is there any reason why it wouldn't work, plenty fresh air coming in there and front fender should be keeping most of the muck off?

The oil cooler in the picture I posted is a 1986-87 Honda VFR750F RC24 oil cooler (its about 10 cm shorter than the long 3AJ oil cooler, 25cm vs 35cm), that is hanging below the headlight on the VFR as orginal place. I don´t need to relocated the oil cooler, but as the long one I have on my 89/90 are a overkill for where I live most of the year, and the location the 3AJ oil cooler has (1VJ for that matter) is kind of puor, as it`s in way of the air flow for the cylinder, I think a relocation would not be a bad idea. But have to see...life is a bit of :fan: right now.....
