Something about oil temperature that might be of interest but may or may not have anything to do with KLR oil temps concerns my KZ650. Since it's air cooled it may provide a totally differennt story but after I put a Yoshimura 716cc kit + ported head, carb mods and header on it I was concerned about oil temps so I put on a thermostatically controlled oil cooler and a good quality water temperature gauge with the sendng plumbed in to measure oil sump temperature. I verified it at 210*f and found it to be pretty much right on so at least that much is a controlled test... . Anyway from what I remember once the bike had warmed up enough for the temperature to stabilize the oil temp in normal riding would run around 180 -190*f except on cold days, as a guess say below 6-7*C and even then it wasn't a lot cooler. On hot days, for Nova Scotia, say 26-30*C flogging the bike on a back road the temps would get up to somewhere around 210*f. If I remember right the oil got the hotest riding 2 up at a pretty relaxed steady pace maybe around 120kph or so and still then the highest temps I can remember were around 220*f. For years I typically ran 20-50 Castrol GTX but in later years switched to synthetic (Motul, Mobil, Motormaster) and seem to remember the temps to be enough cooler that it was quite noticeable although I don't remember by how much. Anyway not a very controlled test but maybe of some interest to some. An aside to this that is also perhaps of interest is that I still have this bike, I bought it new in '77, it has just over 100,000k on it but at about 85,000 I replaced a weaping head gasket an found the cylinders or cam bearing surfaces to be showing no noticeable wear. The 716cc kit was put in around 50,000k so the oil which I change between 4 and 5,000 is doing a good job. Anyway have a great weekend to all especially here where it's a long weekend.......Greg

I'm more concerned with how low the oil temps are in normal riding and how long it takes to get up to temp. But oil temp is very load dependent, so high speed riding with lots of wind resistance on a hot day would be your worst case. I have "stock" wind resistance but did run a test one day when it was 110F, and rode at 75 mph indicated until oil temps stabilized - at just under 240F. For me that's an extreme case; it's much more common for me to see temps in the 180-210 range, and that's after 25 miles of riding before it stabilizes. > > So the point is you need to assess your riding condition. In my case, I don't consider these results to mean that my oil is at "extreme temps". But if you had a passenger, tall windshield, and panniers on a summer ride and drive fast, I'll bet you could get into an "extreme" temp range where that question is a valid one. > > Bill Watson > Phoenix, AZ > > > --------------------------------- > Park yourself in front of a world of choices in alternative vehicles. > Visit the Yahoo!

I suspect you could do the same with the stock KLR seat. I started with a flat Corbin seat and modded it to a semi-dished shape. This gives a reduced driver seat height without giving that deep trapped sensation of an old tractor seat like the Corbin dished seat. 1. I drilled the centers from the rivets holding the cover for the forward 2/3 or the seat and poked the remaining rivet bodies through the base, 2. peeled the cover back, 3. separated the foam from the aft 2/3 of the base using a long tipped flexible knife, 4. starting at a transverse ridge in the base between the rider and passenger positions, I reduced the thickness of the front half of the foam to 1 1/2 inches using a bread knife for slicing and nummerous 1 1/2 inch nails stuck through from the top of the foam to act as depth guides. 5. further shaped and smoothed the foam for final form using a coarse rasp, 6. using the foam as a guide, shortened the nose of the base by cutting perpendicular to the long axis 3 inches back from the front, overlapping it 1 1/4 inches with the base, and reattaching it to the bottom of the base using J&B Weld Epoxy and several screws with nuts (this is necessary to fit the cover over the foam and the base), 7. glued the foam back to the base with silicone and also used the glue to shape and fill in the gaps and rough spots at the edges, 8. stretched the cover over the foam and the base, working out wrinkles, 9. re-riveted cover to base using next size larger of pop rivets with thin washers to match. If you want to see the results, I can send you a pic. It's very comfortable and effective.
