Just run with the R cooler. You'll have to add a 'T' to one of your coolant lines for the R cooler, however that's much easier and costs a lot less than drilling/tapping holes in your new motor.

I've done the same swap with a friends bike and by adding the 'T' we have yet to run into any cooling issues or any leaks.

 

Personally, I would go with the TLR cooler as it should keep the oil at a more consistent temp (being that its liqued cooled and the coolant is tempature controlled via thermostat) and to boot it makes for a more tidy engine and allows you to fit either a TLS or TLR exhaust system. The only downside is that a TLR cooler will not fit a 97 TLS engine:banghead

If you do use a TLS cooler, you will also need to install the restrictor jet thing in the oil gallery.

 

I run my TLS race bike with no oil cooler (TLR Cases) and just used the S Oil Filter threaded attachment.

Different story here in the UK, never gets much above freezing :lol

 

I have a 97' S with a 99' R motor I use the R oil cooler with a tee in the radiator hoses made from copper plumbing 3/4" from the hardware store and soldered together... looks trick. I also did Luminarystl swap with him and made the same cooler tee for him. My engine runs great and seems real consistent temp. wise. It does not overheat either. The bike looks cleaner to me without that big cooler hanging out there.

Why wont the TLR oil cooler work on the 97 TLS??:coocoo

 

The flange on the TLS Crankcases has too small an OD for the TLR Heat exchanger O Ring to Seal on.

 

:stupid

plus the ID is also soo small that if you somehow managed to get the TLR cooler to seal, the crankcase flange would block about 65% of the oil passegway through the cooler.

 

Thanks for the explanation and the pics!!
Looks like I have an extra TLR oil cooler I cant use now:banghead

 

damit i bought one for my TLs 97 then read this :banghead

 

...would there be any benifit to running both coolers - it gets really F'ing hot over here in the summers?

 

What is the average oil temperature on a TL :O

 

:dunno What the oil temp runs at. But oil too cool is bad too.

Nice stuff there.

Prolonged use of a car engine in conditions where the oil cannot reach its correct working temperature will cause sludge formation and crankcase oil dilution, leading to excessive wear especially in the cylinder bores. Optimum engine power will only be delivered at correct temperatures. The elimination of drag in engines caused by cold oil is a most important consideration, especially with a racing engine, revving the engine without a load will not put much heat into the oil and devices for preheating the oil may not be available.
It is therefore desirable to control of the oil flow through the cooler by a thermostatic device, we call an oilstat, set to divert oil to the cooler at 80ºC (although a wide range of settings is available for special applications). This is the minimum temperature required to evaporate and dispel contaminating substances.

 

...thanks guys.

As a practicle matter, Its not obvious to me how you'd get both to work at the same time without hindering the function of one or the other (thinking about that restrictor jet...):O
