Tom Schmitz A squirrel ran by and told me I ought ot look into building a new dash. That required a trip into the Shed of Horrors to retrieve a front sub-frame. On the way in I found the '08 transmission.

Mea culpa, sorry!
Agreed. I only added the bit about the T bob because to say my cooling systems are bone stock would be technically incorrect.

shinyribs Glad to see that threadjacking is not a crime here. I'm pretty scatter-brained and do it often.

I did some stop and go traffic for the first time today. I had an unusual amount of random errands to run and didn't feel like doing it in my non-air conditioned truck. I spent about an hour in town and the fan seemed to never stop. The temp gauge ( no clue of it's dependability, but it seems consistent) stayed in the halfway zone mostly. It went a little warmer a few times, but I do dog the bike pretty good. I've always been hard on rear tires. It was 90f here, so I guess it's doing OK.

It just seems that if you're gonna carry the mass of a coolant tank w/coolant....might as well make it a radiator and get some work out of it.

I'll check the links. Thanks guys!

OOOOOPS! We digress from the topic. Mea culpa, sorry!

DPelletier The Collective has determined that probably the best/easiest way to increase a KLR's cooling is to use the supercool rad from Mylers......even Jeff said so! https://mylers-radiators.myshopify.c...s-side-x-sides

That said, I've had no issues on my "offroad centric" KLR's with the stock cooling setup (albeit with T-Bob's). I think they cool enough for fairly extreme (for a KLR) offroad rides as long as the fan is working........no fan? then it can get ugly.

Just got back from a fairly decent offroad ride which was mostly 1st and 2nd gear with lots of clutch action......my buddy (A level offroad racer) and I both were fairly pooped afterwards and the fans on both bikes ran for a bit when the bikes were shut off at the top of the summit.

Cheers,
Dave

Tom Schmitz Threadjacking is not frowned on here. Just ask Lockjaw...

GoMotor has forgotten more about KLR radiators than most people know.

Over on the .net site Jeff Saline has installed two radiators on his bike; you might want to hunt him down. Very good guy and a regular over there.

shinyribs Be careful what you ask for! I have lots of questions, but I'm trying to use the search function rather than blasting off a bunch of threads.

One thing I noticed while shopping eBay for KL 600 parts was that they used two radiators vs the KLRs radiator/ coolant tank setup. My bike doesn't overheat, but the fan does run constantly. I remember the KTM's I rode as a teenager used two rads and no fan. Anyway, I'm curious if twin rads might be something for me to look in to since I ride offroad at ( apparently) lower speeds than most.

Did I just derail my own thread?

Tom Schmitz Give a shout if you need any help or info.

The Leaning Tower of Midcentury Ugly that TLW and I call a house is undergoing a rather major remodel. Everything that used to be in the house is now in the Shop of Horrors, so I can't find anything. Worse, my access to where I store stuff is blocked off.

If I can do some digging, I'll find the '08 transmission (it might be in the Shed of Horrors, which is more accessible after I move the edger, the lawnmower, the fertilizers, the old KLR tank, forks, and subframe to get to the three containers of KLR Junque) and post up some photos comparing it to the KLR600 transmission.

shinyribs Don't hold your breath! I've been off two wheels for about a year up until recently. I don't have any plans to render my bike useless this season. Well, not on purpose anyway

I'll collect parts and research what it takes to pull this motor down. I'm not new to splitting cases, but I'm new to KLRs. I'm sure there are some special tools that I'll either need to collect or build.
