I like the idea of installing an oil cooler myself considering the temperatures here in FL. But I wonder what the optimum operating temperature is for the engine. You may not want to cool it down too much because that will bring other issues to the surface.

In 1980, I believe YamaMama put a cooler on all xs850's. I had rigged one to my bike for quite a while, but now I use a Lockhart cooler year 'round

T.C.,
Those look like the style pipes I originally had. Nope, doesn't work that way. Wish that it did.

Hey TC

Mate, I already have a factory oil cooler, that's the problem. I want to know why the Mac systems won't fit because it looks to me like they should, the radiator part is up nice and high way away from the headers and the oil lines follow in the front of the frame down to the connection points so how come the Mac system wont fit?

The problem with the OEM coolers and adaptor plates is that they still use the OEM filter cup. The cooler adapter plate is another 1" thick, and this positions the filter cup another 1" lower closer to the pipes!!

That's why I and other's prodded me into making the SOFCA, because it's only ~1.3" thick, and the spin on filter is narrower than the OEM filter cup, and so with about a IIRC 3.5" or 4" diameter space between the #2 and 3 headers near the filter cup, the spin on filter will fit in between just fine! Look at the pictures in the link!

Sorry, times up at the coffee shop I'm using the wireless access at, will have to reply to other ?'s tomorrow!

That pipe looks like a Kerker and Kerker prefers to make a pipe that works well even if maintenance is affected. As TC pointed out you can get that filter out the front. It's a tight fit and a HOT place for the hands but I used to do it that way when I had Kerker pipes on my bikes back in the 70s. Other pipes that do not affect the oil filter re & re will not delver much added power like the Kerker does. a well tuned set of stock carbs and a Kerker will add about 15% more horse power. It's one of the few pipes that really adds power to these bikes. TUNE it and KEEP IT is what I say

Pipes and SOFCA

Thanks for all the replies!!

TC,
The pipes are Kerkers and after all the advice/information I will be doing a lot of measuring. Unfortunately its been raining here since last Friday and as you can see in the pictures The "G" lives under a carport susceptible to getting wet when the wind blows during rain storms. Ok, Ok, I know what you're thinking.... I do have a cover for it and I cover it when not in use!!

TC, thanks for the suggestion regarding the SOFCA. I will definitely measure the space for fitment and get back with you on it. Since the G does not have an oil cooler any suggestions as to make, model, mounting method/brackets, hose routing, etc. will be appreciated.
I want to do my own oil and filter changes and this seems to be the ticket there.

79XS11F,
The original owner told me that's why he installed the Kerkers and jetted the carbs to match. He said the difference in power was substantial. I am very happy with that since I didn't have to go there. The only issue I have now is that the guts of the tailpipe are starting to rattle some. My mech suggested I take the insides out and sodder/weld the loose parts and put them back in since thay are still pretty much intact.

Wildkat,
I've been reading a lot about the Progressives and I'm definitely giving them serious consideration. Except that the ride has not deteriorated to the point where I can justify the price of the progressives!! Maybe if I loose some weight the problem will go away!!!!

My focus now is going to be installing the brightest lights possible and the modulators for them.

Perhaps the baffle material is due for replacing. If the baffle is the same as what was on my Kerker it will be about 2.5 feet long and fully perforated on its length. If the wading is worn out the and will contact the pipes in the colectlor area and rattle. Don't pack it too tight if you have to replace the packing material.

Rob,

That's what I was thinking, I just need to pull out the guts and see what's going on in there. I'll keep you posted.
