Engine Oil Cooler

All righty then. This isn't a big topic on here but I seriously believe half of the engine heating problems come from lack of oil cooling. I'm gonna venture out and try adding an filter adapter and a cooler to my bike. Experienced opinions welcomed.

Adapter link. 99 percent sure it will fit in the space but I'll have to put elbow fittings on it.

what ever floats your boat man... I personally don't think our cooling issues stem from the oil not transferring heat correctly, but rather from improperly maintained cooling systems. An oil cooler is only going to be a band aid to the actual problem... you know you could have picked up an oil cooler from NAPA or Autozone for a lot cheaper, and it would have come with the connectors to splice into our existing oil lines.

most of the bikes with oil coolers are actually listed as air/oil cooled, meaning that they depend on the oil and a cooler to help keep temps under control.

another thing to note... an engine that runs 10 degrees too cold is actually doing more damage to itself than an engine running 10 degrees too hot (as long as we are talking that the heat is coming from inadequate cooling and not something like timing, or plugged exhaust).

All of the cooling system issues I have seen on the boards here have been from a part of the cooling system failing, not from the coolant not transferring enough heat away from the oil... Well er ok, so a clogged radiator won't allow the coolant to pull heat away from the engine and the oil, but that is because the circulation is blocked, and no heat transfer is taking place. But like I said earlier, part of the cooling system failed.
Most recent case of engine failure due to excessive heat was due to a faulty impeller shaft circlip, which allowed the impeller to slide off the shaft, and stop circulation of the coolant, resulting in no heat transfer and catastrophic engine failure.

Putting the axillary oil cooler on will only help cool your bike while the engine is running, but won't help while idling at a stop light, where we need the extra cooling the most.

Thumbs up Good idea.

I like oil coolers,especially those neat candle stick types, there slim easily mounted, and don't interfere with normal air flow. I'd rather have my engine running cooler than on the edge of boiling, specially as it's an older bike, with a larger chance of cooling system failure, than not. Perhaps even run a lighter grade of oil to compliment the lower temperature.

As always I value your opinion,,, but I also think your wrong. I to do mechanical work with 2 years mechanical school and 35 years of wrenching to go with it. I do believe oil has a lot to do with cooling an engine. Water only circulates in the outer portion of the engine case and heads which is already exposed to cooler air. The 750 has what, 1 1/2 quarts of coolant with only 1/2 being in the engine at any given time while half is in the radiator, neck and hoses. the latter two are hidden under the tank and are not exposed for cooling purposes. The engine also has what, 4 quarts of oil that is in the engine that isn't exposed to any cooling source other than the filter and the bottom of the engine case which both are the closet thing to hot asphalt other than the tires. Oil cools more fiction producing parts than water/coolant ever thought about. Bearings, cams, chains, crank shaft, rod, transmission gears, stator, drum, and balancer shaft and gears are all cooled by engine oil/heat transfer.

With all that said, I don't have major engine heating problem. Radiator has been dipped and engine clean well. But here in the South you will see a tree sweat in the middle of July/August. After a lot of hill/mountain riding you'll will see the temps going up and the fan running more often than not. Hills = engine load = friction on the engine internal moving parts= higher internal engine heat = oil reducing internal engine heat by heat transfer to oil = oil with higher temps! Oil is totally contain in the engine case. Cooler to remove high temps from oil doing it job. FLOATS MY BOAT very well. More than not in the last decade bikes come factory with oil cooler. Not a radiator.

As to cutting in to the oil line to the head. nah! My bike is my baby. I don't half azz nothing on it. I don't want to just cool the head which is exposed to fresh air and coolant. I want to cool all the oil that is doing heat transfer for internal parts that are not coolant cooled.

Chuck, I couldn't talk you into an oil temp gauge? That is info I would like to see.

If I find an inline gauge small enough I mite just do that. Put the filter adapter on and put it into the lines before the cooler is added. I'm thinking the engine temps staying down to common operating temps with less fan time will let me know that all is worth it.
