That oil cooler radiator is the same one that came with my Lifan 140cc engine from DRATV. It evidently had some sort of blockage because the oil pressure caused it to balloon and crack spraying oil all over my garage floor a few seconds after starting it for the first time. Doubt that would happen with the CG engines because of where the oil is tapped and diverted but I'd keep an eye on it.

That's a good point. It would be advisable to fill a new cooler with oil before installation, to confirm good flow.
If an oil cooler were to fail out on a ride, it could be disconnected with some simple hand tools, although the banjo fittings would still be exposed. One of the hoses that is routed to the cooler could be re-routed between the two banjo fittings to allow one to continue riding. One litre of oil might be required, so always travel with one.

Certainly it would. The TT is based on the same CG pushrod motor.
Thermostatic bypass creates complexity. I'd rather have the valve on the valve cover, which would allow me to close off the cooler in colder weather.

It would take 3 valves unless a guy was able to source a 3 way valve, Then you would need 2..... |

it normally involves one valve that opens to allow flow around the cooler. the resistance of flow in the cooler allows most of the oil to bypass it. there are manual bypass valves also and all they amount to is two T fittings in the oil lines with a valve between them.
doesn't get a whole lot more simple than that. here is an example of a thermostatic bypass valve. http://www.amazon.com/dp/B008BTJFJ4/...I1DY8YRKYTBGYJ how it works

Oil needs differential pressure to flow, so it won't flow backwards. A valve made like the animation above doesn't shut off the flow to the oil cooler, only in the bypass. Even with the bypass valve fully open, part of the oil flow still goes through the cooler. |

The CG oil cooler with a valve on the valve cover would be the most foolproof. It's a simple lever on top, and when you close it, oil is not routed through the cooler.
I did a quick search, but I'm not finding any examples right now. I know I've seen them, and that's the version I'd choose.

The perfect solution.

I put set of these on:https://www.rockymountainatvmc.com/p...lex-Handguards, they mounted up really easily and appear to be very strong.
