I know that there are many choices when it comes to cooling our oil temps and what units to install.  Seen a few bikes that have the 10 row lower bottom of down tube mounted Jagg, and some have twin 10 row oil coolers mount on the down tubes.   Would like to know what is and would be the best installation for an 09 SERG with lowers on it?  Any input and pics would be great!   Thanks!

I  have installed the Jagg 10-row down in front of the voltage regulator for several customers and all reports are positive. Use the J4600 adapter and be sure also to get the anti rotation device as it keeps the adapter from rotating when removing and installing the oil filter.

After the oil cooler get this to keep your oil cool while sitting in traffic.

I replaced the H-D center mount oil cooler with twin 6-row Jagg coolers on the down tubes. Additional cooling was good for 15-20 degrees, but I don't think it will work with lowers.

Did you use the Jagg adaptor? Or stock  SERG adaptor?  Thanks Doc

Doc,

Using the stock SERG adapter since it's already installed. If I were to purchase a completely new system, I would opt for the Jagg adapter.

[HDDOCFL]

What were your temps before the Jagg coolers install. And what are they now? also what out side temps?   Thanks Doc

First I assume you have seen these pics, but thought I'd post them again, I installed two Jagg ten row coolers after read Donny Peresen's book , he highly recommends there use, to do the right side you have to make the bracket, from my conversations with Jagg they are considering making one but I've seen nothing yet, it's just a reverse of the Jagg left side bracket but with the arms longer, we did some engine work and bumped the compression up to 10.5, I now have over 17K on the bike and have not had any problems with over heating, like ALL coolers when you sit in traffic, the coolers don't cool, but as most of my riding is long trips they work great for me and if I do get caught in traffic once moving again the engine cools down quick, most times the bike runs at about 185-190, (themostats don't open until 185) In real hot weather I might see 210, that crap about 245 being OK is just what it is......... crap. Install is straight forward, I run the the oil though the right side then over and though the left side then back to the jagg oil filter adapter. The jagg coolers are ten row, the HD is 8 row, to get the same cooling effect the HD cooler slows the oil down, that results in a pressure drop, for that reason you should not use and HD cooler with an additional Jagg, Jagg coolers have less pressure drop so you can use two in tanden without a problem. In the end how much cooler or how much faster does my bike cool down, who knows but with all the past problems with the 110 motor I decided it can not hurt.

I have a question on the coolers you have, or better said, on the install of the coolers you have.

If you're going to put them on and have them "out there", why would you not have them facing the air flow rather than mounting them on edge and then blocking what air flow there is with the flat plate mounting brackets?  Air only free flows through the core in one direction, not 90 degrees to it.  I realize just being there they are producing some heat exchange from the oil to the air, but they could be so much more efficient if mounted flat with the brackets just on the inside edge to the bike frame?

I know function over looks.  They're not as clean looking as the OEM cooler they're replacing but are probably a lot more efficient.  I'm still curious to know the reason you mounted them in this manner.

Nice bike by the way....   Orange/Black definitely the best looking and the fastest!!!

I figured I'd have to explain that When I started with this project the first thing I did was talk at some  lenght with the great folks at Jagg. Here is what I learned. For many many years all their coolers were installed (& tested)  facing flat side to the wind.   Keep in mind, Jagg, while a leader in cooler tech. is a small company. As part of their duties they were visiting the pits of several of the Nascar teams that use their coolers,  in many cases as transmission coolers. While at the rear of one  of the cars they saw a cooler put "on edge" towards the air flow.  They warned the team that the cooler was never designed for that install & as such was not work well "edge on".  The Nascar guys just smiled winked and said, have you ever done any wind tunnel testing @ Jagg, they said well not that much,  The Nacars guys went on the say, did you notice the "angled lift" at the front of the cooler?.  Looking again "oh yes what's that for?"   Nascar by using wind tunnel tests found that by installing a "lift" at the front of the cooler, then putting the cooler "on edge" to the air flow that MORE  air traveled though the cooler because of the low pressure area created on the backside of the cooler   than if it was put face first.  Now you know too why Jagg now  puts  "lifts" on every vertically mounted  ten row cooler they sell.  Neat .    PS by the way, in I'd say 90% of the time when others look at the bike they never even notice the coolers are installed.

Jettjockey !!!   you should not use and HD cooler with an additional Jagg, Jagg coolers have less pressure drop so you can use two in tanden without a problem. In the end how much cooler or how much faster does my bike cool down, who knows but with all the past problems with the 110 motor I decided it can not hurt.
   



I did try the jagg 10 row vertical in series with the HD cooler and adaptor, and it was a big let down ,also I believe it made the engine sump by taxing the oil pump. I am back to stock now till I can get some $$$ together to try out your same set up.  Thanks Doc

Can you run that set up with lowers on?
      

[jettjocky]

NO,
1) don't believe there is the space for both
2) with no air running over the coolers they will not work.

It's not that hard to fabricate the right side bracket, just reverse the left side & make the arms longer to clear the exhaust header and rest inside the brake peddle.  However  prior to doing so,  you might want to call Jagg, as I believe they at one point were considering offering a right side bracket.
