I have been using 65ml oil cooler on my CG250 for almost a year and I can say that these air cooled engines need it, mine is fan assited with a 4" fan relay and manuel switch, without the oil cooler the oil would exceed 265°F when climbing hills and long rides and traffic lights in the city, now 180°~190°F all day riding, uphills, and days where outdoor temp is over 90°F. Without the oil cooler oil changes where 1300ml now with the oil cooler 1500ml. When changing the oil I empty the oil cooler removing the 2 hoses every 1000km or 600mi. The crush washers need changing also.
Interesting design but I see a few issues - Would this not make adjusting the valves more of a pain when it comes time? Your website seems to have no specs listed at all? Dimensions, capacity, nothing. At twice the price of a normal CG250 oil cooler I would expect some sorta information to make sure it's not just a waste of money. How much does it actually cool the oil temp? Who knows if it's any better or worse than a normal one with no specs about it?
Has anyone conducted tests to compare the cooling ability of this particular system with the ones that traditionally emerge from the bottom of the engine? Furthermore, what would be the potential outcome if both systems were installed simultaneously?
Is the button head bolt necessary for clearance? I ordered a kit off aliexpress similar to this one and it doesn't include that bolt, but getting one at the hardware store shouldn't be an issue. (edit: just check the valve cover fit without the gasket installed, details in the replies)
Note: button-head bolts can be difficult to find. If your local hardware store does not have them, I suggest *bolt depot.* They are online. I’ve bought fasteners from them before on a number of occasions, including *button-head bolts in several sizes.*
@@capcycling6578 Late reply but just for others looking for info. Check whether the valve cover fits flush with the cylinder head without the gasket installed. You check without the gasket since it sticks out but gets squeezed down once the bolts tighten it down. You'd probably damage the valve cover trying to tighten it down with the gasket installed if you do end up needing the clearance with the bolt. I installed my oil cooler valve cover just fine on a stock hawk engine without swapping the bolt. Later, when I installed the motocult big bore kit with the shim on the rocker assembly to compensate for the decked(shorter) cylinder, the bolt became necessary. The valve cover (due to additional passages) would hit the original bolt before touching the gasket surface, and kinda wobble around not sitting flush.

I did everything but bleed that exit line. Will it jist fill on its own after a ride or should i take back apart.

where do i get that kit plz thnx
Probably not as effective, but simpler, *if* it can fit: add *substantial* finning to the valve cover.
why replace that rocker bolt?

Yes, you will need to install a button head for clearance.

IS it okay not to replace the button head bolt?

How long is the push rod pls n thx
There are different lengths of push rods depending on the manufacturer of the CG250 engine.
My bike is a hawk 250cc so i believe they carry the same or similar length
@@nahjohnniyedavis6043 they should be 153mm long
Any updated on the strage 3 kit??
What updates are you inquiring about?
@@devinbiek5951 I was hoping for a results video. Maybe showing the way the bike sounds and rides now after the big bore kit install?
@@kevinalcaraz6904 Send me an email and I’ll make a video for you to hear how the bike sounds and rides. MotoCultparts@gmail.com
@@motocultparts2496 sent!
Why would you need to bleed an oil cooler? The oil flowing through it should purge itself of air.
