Your gas mileage will go to about 16/15 of what you had and your engine revs will drop to about 15/16 ths of original numbers. I I have put on about 30,000 km with the 16 tooth, and I've had no problems. Some people claim that the power loss from the top end makes you work the engine even more, but I have not noticed this at all. I don't claim to be racing Hayabusas' either. DC joenowlin wrote:

Note that it takes the same amount of energy to shove your bike at 70+mph no matter what rpm the engine is going, and this is the main predicator of gas mileage at high speeds. Running the engine at a lower rpm may increase the efficiency of the engine slightly, but the main energy usage at those speeds is simply shoving your tall bike thru the air. I've never heard of anybody who got the 5mpg gain in gas mileage that you're claiming from the sprocket change. Well, not folks who are going fast enough to need it, anyhow .

The question is not one of "working the engine more", the question is one of simple physics. While an engine running at a lower rpm is slightly more efficient than one running at a higher rpm, it takes the same amount of energy to push your bike thru the air no matter what speed the engine is running. The difference in engine efficiency between 4600rpm and 5000rpm is probably not that significant, though the reduce in engine vibration (and increased comfort) may make the sprocket change worthwhile for you. -E

I've had my 16t sprocket on for about 2 months. I love it. I have no idea how it has affected my gas mileage. My KLR is basically street driven. Revs are cut about 450 RPM at 100kmh. You have to work the lower gears a bit more but 4th and 5th are AWESOME!! Up to 90 kmh and sometimes even 100 kmh I am in 4th gear. 5th is almost an overdrive gear for me now. Pay a few bucks more and get a good sprocket. I think mine is made by PBI. Cheap ones could be out of balance and affect vibration. Also be ready to fight that sprocket nut for first time removal. It's best to have a helper holding the rear brake. You'll probably need a breaker bar. The washer can be used again, no problem. Jake makes a nut that you just tighten and you don't have to worry about torque. However, if you intend on leaving the sprocket on permanently, just flatten the existing washer and use a NEW part of it to bend over the nut to lock it in place. Good luck!!!

I've ridden enough from Jax Fl to Anderson S.C to know that I get different gas milage from three different sprockets 14,15,16. --- In DSN_klr650@yahoogroups.com, "Eric L. Green" wrote:

Obviously an inferior FAQ, since the "real" FAQ makes no such complaint, as miles and miles of experience from numerous riders have attested. Kinda like the WD-40 chain lube argument. Krokko

Hey, then lets just call a spade a spade. I bet the original poster was referring to MSM, the source of all kinds of apocryphal lore about the KLR.

I have an '06 with the same misaligned instrument cluster. I fixed mine by not looking at it. Now it's just fine. Don Spike55 wrote: My instrument cluster seems out of center too.
