I think i may have found a way to see if these are viable. put it together cycle the engine a few times (let cool) and disconnect a hose and put your thumb on the end and see if it has any pressure.

How do you run setup magnet in the loop? does the gy6 even run that hot? I modded my CVT cover and temps went down.

That would work. You could actually start the engine and see if oil spurted out of the line. A few seconds wouldn't hurt anything.

There's a magnet?

I did some testing with an oven thermometer a while back. You go on a ride an stick the Martha Stewart in right after you get back. The lowest I saw was 230 F and it would get up to 260 on a hot day:

Modern oils can handle those temps but it's a stretch. An oil cooler would help but you can change your oil a lot too. As you said, there's debate about whether those coolers even do anything. Also, could they even be hurting the cooling process by rerouting the pressure? Something to think about.

Sure, get some more air flowing through the cover, increase the radiating surface, it acts as a heat sink for the case, makes sense. Rich

in that case they could make finned CVT covers, it would take much to go on alibabba and order a container oh CVT covers made to your specs if a gy6 parts seller was willing to invest the money.

Yes magnet, i run magnetic drain plug just for the added insurance, you never when little something something might find it's way in after rebuild or oil chance. my guess though if any thing if does pick something up there is gonna be a lot and it won't be good.

also is the debate on weather they work based on the oil pump volume? would the volume depend on scoot to scoot due to the cheap nature of the gy6?

Another thing where are people mounting these at?

scrappydog has one on there 200cc ask them they can tell you they really work

[cdoublejj]

Yeah just like their A9 cams, which i bought and was completely Fked up and made the scoot unrideable and yes it was installed correctly no ifs ands or buts. I would not trust their opinion or just any other seller (they are there to sell). I have friend who is a very skilled race/engine builder who I've been going to for advice and so far i have to say the mods the make the biggest difference are the home grown ones. /rant

also i wonder if any of these would fit a GY6

I wonder if a person could find a epoxy that could transfer heat or conduct it so that some fins could be attached to the bottom of your gy6 to cool the oil with in it. fins such as a computer uses to cool the cpu except much larger. That would be lot better in my opinion as it is non invasive and not apt to cause a leak. john

I know people that have adapted heat pipes.. they seemed to work OK...

[cdoublejj]

Arctic silver makes an epoxy i'm not sure if it is up to those temps though because they stuff is actually removable with enough heat. People say the stuff is permanent but, it isn't enough cold or heat and it pop off with little force.

i suppose if once had a way of mounting on aluminum heat sinks you could use regular thermal paste how ever they run hot enough i'm sure they would work with out paste.

There is also an additive you can put in your oil to conduct more heat it usually helps to have an oil cooler though.
