Thanks for all the replies and suggestions. Oil cooler, and lower gear ratio sound like great ideas. Anyone have any suggestions on a decent oil cooler.
The more I drive this thing the more confident I get. I have stuck to mostly secondary highways, love traveling country back roads. So far I've taken it on a 200 mile trip, and just over the weekend another 150 mile trip. Bike ran great on both runs. Thinking about putting another 400 miles on it this weekend camping out in the Adirondacks. I definitely plan on lowering the sprocket size, and will before I do any long distance straight highway riding. For the most part it does pretty well on the highway between 55 - 60 with the stock sprocket, you can really tell the engines working though. I would definitely like to lower those rpm's before going any serious distance. I'm really impressed with how the light bike handles on the highway too for the most part. Thanks again for everyone's suggestions and replies. Much appreciated. |
Here's one like I have. https://www.aliexpress.com/item/CG12...a1554e1c417690

i don think the bikes need oil coolers on them ,unless your doing a ton of city rideing,in 1975 they did not have them on the 125 version,highway rideing gives one plenty of air more then one needs to keep the engine cool ,now again though i know personal choice hear ,the one that goes behind the front covers ,if i was going to get one would be the one ,the one that comes out the side of the engine down lower looks like it gets in the way .and in the south during the hot season may help too? i wonder how much more oil the engine has to have running through the cooler ,my thought being the bigger oil filter is not allways better ,as the engine has to push more oil around then it was designed to do

The oil cooler is design for cooling the oil. Keeping the temperature lower on the oil will prevent the oil from breaking down as fast thus longer life span of oil and engine components. The cooler oil temps will cool the engine a little. Maybe 10 degrees but the main purpose is cooling the oil. To give an example. Before I installed the oil cooler the oil would turn black before I could put 500 miles. I changed my oil a couple of weekends ago. With a little over 1100 miles the oil was a dark golden brown. Cooler oil temp also help keep the clutch cooler. No problems finding neutral once the engines up to temp. :tup:
It takes about 1/4 of a quart more oil which will be a good thing. |
you have the one up in the front plastics area ?? ,i say while they may not need one in every case ,i wont say never on this ,i just wonder how much more oil flows though the cooler ,or does it flow through the cooler needing more oil ,i would think it needs to flow through the cooler to keep it cooler right ,a month from now when in get the other mods done who knows they look cool in the right spot

The oil flows through the cooler. It take about 1/4 of a quart more oil. I have the mounted up under the tank plastic.

The CG motor uses a large portion of the oil pumped through the system to cool the cylinder head. Plus, oil starts to break down and oxidize as well as lose its viscosity and lubricating capabilities if it gets too hot. The ideal oil temp range is around 180-200 degrees in a piston engine. |
My air-cooled street bike (v-twin) has a Delphi EFI system that will actually prevent the cylinder head from getting too hot by cutting spark every other cycle until the temperature drops. It has a small oil cooler, but it does happen very rarely!
The 'stutters' spark mode has only happened to me on days over 100F and when traffic was jammed up. |

The system continues to inject fuel to cool cylinder. |
