Those look very cool. Likey!

Hi All,
Anyone have contact info for John Smarsh?

Thanks

Very cool and informative thread. Living in a city with some of the worst gridlock in North America, I worry a hell of a lot about some of the heat and noises I have coming from my beloved inline 6 when stuck in traffic on a warm-to-hot day. No scary smells yet, but it's good to know that a cooler like that can have such an impact. TBH, I had never heard of an oil t-stat like that, I like the idea of speeding warmup while putting a lid on the higher temps.

Same question from me. Is he still around and making his kits?

I don't think he is coming here at all anymore. You may try CBXWorld. His name there is 415zr1, I believe.

Hey all - I have 4 questions about the Earl's coolers:

1. What width are people using? It looks to me like the Wide is the right size (body width is 13", core width is 9", center-to-center width on the fittings is 9-3/4").

2. For having AN fittings welded to the OEM fittings that attach to the engine, should I just get straight fittings and then have one end cut & welded to the OEM piece? If so, what's a good fitting to start with?

3. Are the Earl's fittings worth the extra money over something like the Jeg's brand fittings? With all of the fittings & couplers required for this, the difference could add up to over a hundred bucks. I notice a big jump in price from Jeg's to Earl's, and then a similar jump from Earl's to Aeromotive.

4. Is -10 hose appropriate? The fittings on the cooler and the t-stat are -10, but the fittings can reduce down to a -8 or -6. I assume that the cooler is on the low pressure return side of the lubricating system and that the big hose is desirable, but some confirmation would be good.

Thanks!

From the dimensions and photos in the first post in Smarsh's post on the other forum, it really looks like the Wide, not the Extra-Wide. Based on a length of 14.7" for the top bracket, I took measurements in the photo and estimated that the output holes are 9.9" center-to-center. The dimension for the Earl's Wide cooler is 9.75" c-to-c. The Extra-Wide is 12.125" on that same measurement, so it really does seem like the Wide is the cooler in question.

Placed a big order for hoses, fittings, cooler, and t-stat with Jeg's just now.

Here is what I am doing. I am using a standard Racimex oil cooler. It has "banjo fittings" on the cooler, but they are easy to get and incorporate into oil lines with the CBX motor connections on the other side. Simple fabricated brackets connect to the stock oil cooler brackets.

Very cool setup.

I ordered my parts for the 13 row cooler, t-stat and A/N fittings yesterday and the plumbing drives the cost way up. So many fittings and couplers - and that was going with the cheaper Jeg's fittings - if one shelled out for Aeroquip it would be mental. But I decided to go with the A/N fittings and hose ends instead of push-lock & hose clamps because I really do think that they're very cool. A cool bike deserves cool plumbing. :)

Thermostat on an air-cooled motor?

Why bother?

I believe it is for the same reason they are used on liquid cooled engines. If you have an efficient oil cooler, it is possible, given the right conditions, to cool your engine too much.

Looks great Mike.
Will there be much of a restriction in the flow through the small hole in the banjo bolts?

Barry: Shouldn't be a problem. It doesn't show well in the picture, but there are four holes in each banjo bolt.

Precisely. I put a big cooler on there - the thermostat will help it get up to temp faster, and make overcooling less likely. Overcooling is not a rare event if you take every opportunity to ride in Toronto. I feel like the more time it spends at or near optimal running temp, the better the overall engine health and oil consumption will be.

Also - why engineer when you can overengineer? I mean, a bike doesn't need 6 cylinders.
