Thanks for the info Pat. I'll just go with ~1/3 of total travel then. Can anyone confirm that the KLR650 has 9 inches of rear travel? Thanks, Ted - Denver

I've read that just like the fuel tank spec, it's actually less. Like about 8 inches. Why don't you measure yourself? It only takes 3 bolts and 5 minutes to drop the shock out of the bike. MrMoose A8 (Barbie and Ken special)

Ok, good.

Ok, also good. I wanted, and got the same thing. Here's the place where a lot of guys go wrong though. To run it "a TOUCH" richer to run cooler..........you need to adjust your card only "a TOUCH". You can gain that through turning your fuel mix screw 1/2 turn at a time till the temp drops. (probably not more than 1 full turn) Not much huh? It's not, but the slightest changes in adjustments on the KLR carb make a big difference. Changing the main jet size, even if your going just 1 size is a HUGE difference. If you did that (as many guys have) you will lose top end speed, top end power, and many mpg. Don't do it. Anyone wanting to play with their fuel mix on the KLR should first ride the thing and pay attention to every single thing your bike is doing that relates to your carb. Your bike will tell you how/where to adjust it. How it starts, warms up, comes off the choke, leaves from a dead start, wheelies, how fast it redlines in each gear, operating temp, mpg, etc etc and write it all down. Then make one small adjustment, and start over with the riding/testing/writing down process again. I've learned that with the KLR, there is a VERY SLIGHT gain in a few different area's while adjusting the carb a LITTLE BIT. After that anything you do to continue richening it makes your gains take a nose dive hard and fast. Save yourself the hassle and heed this advice. I have found myself dialing in bike after bike now because so many guys are just tossing in this and that and adjusting here and there, and you just can't do that with a carb. The last one I just did brought the guys power way back up, and his mpg from 30 to 49.6, and that's on Ca fuel. MrMoose A8 (Barbie and Ken special)

Just open up the air/fuel mix screw 1/2 turn. MrMoose A8 (Barbie and Ken special)
