klr stock kickstand

Interesting. I didn't think you had an overflow res. I'm amazed it can fit in that location. And I always thought you had dual fans. Clearly, at speed you have quite an efficient cooling system; however, under slow, demanding conditions, it's only marginally better without a second fan. It sounds like it serves you very well which is what matters. You don't need a reservoir if your marginal cooling rate is satisfactory. In fact, I have never blown my rad cap into the reservoir using a 50/50 mix even with one rad/stock setup. As far as prices I was throwing out, merely I priced an OEM radiator ($310) and OEM fan assembly ($313) sans relay, sensor, etc. So even if you could simply mount a second stock rad and fan, it'd be over $600 just for these two parts retail alone (my point). But it's not a plug and play scenario anyway. You'd need different hoses, connections, routing and a manifold design to optimize the cooling. For example, dumping one hot radiator into another to cool it further isn't as efficient as distributing one source into to two independent radiators with fans. Now, Jessie Jame's Monster Garage might be able to cobble something together over a weekend (not one day, for sure), but it would not be engineered/optimized. Just relocating the reservoir (keeping a stock look) would be a challenge. It's big. Plus reconfiguring wires, relays, horn, etc.? It'd take me more than a weekend...I'm certain.

SNIP <><><><><> <><><><><> What most folks that do this have found works well is using a right side radiator from a stock dual radiator set up. I chose the KLR250 right radiator, fan and overflow reservoir. Coolant flow is from the head/stat housing to the bottom of the right radiator, out the top of the right radiator and into the top of the left (stock) radiator and then out the bottom of the left radiator and to the coolant pump inlet. I do have dual fans. One on each radiator. Adding the fan on the right side radiator required relocating all the electrics normally in that area. The fans both trigger off the sensor in the bottom of the left radiator which is the coolest coolant in the system. There is no sense in using a fan(s) if the coolant is already cool enough from passing through the radiators. And I've found that is the norm and not the exception. The KLR250 overflow bottle is much smaller than the stock KLR650 overflow reservoir but works well. Again, mounting it in the location I chose requires lots of work. After I completed my dual radiator set up a local motocross shop owner and I were talking and he showed me a bottle from an MX bike. It was hanging from the left side of the sub frame. I think that would be a great location on the KLR650 and very easy to plumb and mount. Combining the dual radiator setup with a Thermo-Bob or similar stat housing with by-pass works great. In cold conditions I still have coolant at operating temp in about 2 miles after start-up. A 195 degree stat is just about required to allow the coolant to get hot when using the effective dual radiator approach. Without the hotter than stock stat the coolant will never get to operating temp in temps below about 70 degrees. Two radiators are just too effective for the amount of heat generated in this cooling system. I think dual fans on a stock radiator is more work than will prove worthy. I think an easier way to get better cooling is to increase the cooling capacity using a tank plumbed into the upper radiator hose. It would be pretty easy to make from aluminum tube (a very good heat transfer metal) with a couple of nipples welded on the ends. Maybe make it so it would hold about 8-10 ounces of coolant. It would kind of act like a second, not so efficient radiator, and could be mounted near the front down tube reducing or eliminating many of the issues associated with adding a second radiator.

Jeff - In most cases, coolant passing through one rad + fan (stock system) at discharge will be cool enough. However, under extreme conditions and slow velocity, I'd sure like to measure your dual system vs. mine. Maybe places like Moab, Death Valley, Baja, Anza Borrego. My system runs very hot and constantly in all these places except at higher speeds. I don't have a Thermo-Bob, but I understand its value. Kaw cut corners in many KLR areas including the cooling system. However we've all come to conclude (for its value, at least), it serves many if not most riders very well--as is. It's a few of us that must tweak to squeak out that last bit of special utility. I'm very inclined first to enhance the OEM circle shroud, fan size and proximity. Next, I'll consider adding a second fan (several types on order) to see what it offers. Really speed solves the problem, so initially I'm sticking with R&D focused on marginal cfm/sq in. until my results say go fish. Now, what a bugger moving all relays, wires, horn?, etc. to accommodate #2. I don't think a stock 650 reservoir would fit anywhere else internally, so you have to go smaller. My BMW heated vest port is where the old kickstand switch used to be. I do like your setup, but at this point I'm not interested in dual rads simply due to vulnerability and cost. Adding some aluminum tubing without a specific way of cooling it won't help (at least until velocity increases) as 8-10 ounces will heat up within minutes and simply become a heat sink plus add another point of failure.

I've enjoyed reading the many posts on the cooling issues, and there seems to be an area I've missed if its been covered. I think before I did a bunch of expensive (in money and/or time) mods, I might consider what I could do to improve stock radiator and fan system. Shrouds have been offered. Yet, what about the possibility of increasing the fan's RPM or replacing the motor with one that spins faster? Alternately, what's the potential of changing the pitch of the fan blades to increase air volume and/or force? (might have to space the fan out from the radiator depending on pitch angle) We do it all the time with props on airplanes and boats. A combination of the two? Just food for thought.

I am looking for a good condition stock size KLR kick stand if any are selling. Thanks Crash
