GS650G vs. GS650M

BassCliff, I don't believe this oil cooler connection will work on the shaft driven 650 motor since they don't have the oil pressure switch on top of the crankcase like other motors....

Hi Mr. waterman,

I was afraid of that. Thanks for setting me straight.

Mr. darkbane,

I hope you get it figured out. When you do, please share with the group. :-D

I'll hang up on myself now. 8-[

Thank you for your indulgence,

BassCliff

I've been wanting to put an oil cooler on my 83 gs650g and I finally found one on EBAy for a great price. It looks as though it goes on the Katana 650 of the same year.

I'd like to know why you want to install an oil cooler. Have you measured the oil temperature and seen a problem? If so, what do consider a high oil temperature, and at what ambient temperatures and riding conditions do you see high oil temperatures?

Or, is it just for the bling factor?

It's not necessarily for Bling factor considering I'm putting it on a cafe style bike.

I don't have an oil temp sensor on my bike (looking for one). Almost all of my miles are stop and go (seems like more stop than anything) traffic. Chicago isn't a constant 100 degrees in the summer like some states, but it can't get pretty damn hot and stay hot for a while. I ride a lot and sometimes hard, so I guess I'd just like the extra confidence that I'm not doing any harm to my bike. On the super hot days, I seem to feel a bit of a performance difference.

I definitely don't think that there is a need for one constantly operating that's why I'd want to install the inline thermostat bypass and have the cooler for when it needs it.

Plus I'm not used to running at 5000-65000 rpm on the freeway (freaks me out a bit).

I've already read the other threads with this debate, and everyone seems to have their own opinion. If everyones opinion was that it would have no advantages whatsoever, then I probably wouldn't even give it a thought.

Cheers

I don't have an opinion I'm pushing - just looking for information.

I've been using the bike for local trips lately so I can avoid riding at more than 90 degrees, which happens a dozen or so days a year here. However, I'm hoping to get back into touring on it, and it's not always possible to avoid riding when it's unbearably hot. In the first few years I owned it I rode in some really hot weather without any sign of overheating, but I was using 20W50 oil then. I switched to 10W40 for a trip to the Yukon, and found the engine became really noisy by 2000 miles. However, the gas mileage improved by 20%, so now I'm using 10W40 synthetic (Motul). which seems to last a lot longer. I'm hoping it will be as resistant to heat as 20W50.

If you eventually get an oil temperature gauge, I'd be very interested in reading a post of your temperatures for various riding conditions.

I've been looking around for oil temp gauges but haven't had much luck. I like the look of the type you replace your oil fill cap with(I've heard they may not be as accurate though), but they seem to come and go on ebay and the only store I found that had them was in the uk and they didn't ship over seas.

I know there's a guy on here that sells some pretty nice ones that tap into the engine block, but the last time I looked, the ones for the 650's required extra hardware and mounted in a weird and odd looking place. I'll post a link when I find the thread.

Suggestions?

If you're running 65000 RPM I'd like to hear that motor sing!!:-D

On the rear of the head there is a bolt that I believe goes into the oil passage for the valve train. If the pressure there is different from the pressure at the filter cover you could induce flow from one place to another. Run it through a cooler and there you go. The small opening in the head would need an adapter but that would help form a natural restriction. Restriction is needed to prevent pressure from being dropped in the valve train. You would also need lines and additional oil to make up for the system.

An Aussie sent me pictures 2 years ago of his Katana filter system and when I saw the different oil pan I abandoned the idea. But if the head can provide a return or supply source then it could be possible.

The bling factor of course makes it worth it.
