Please explain what your thinking about. 16 tooth sprocket or big bore is kind of a comparing apples and oranges thing. Alan A13 Iowa gbennett69 wrote:

This question is confusing. What is it you want from a KLR, more low end power or more top speed? Many guys seem to think a 16T with the stock 43T rear sprocket is too much gearing for a KLR motor, ie, lugs it down too much, makes it work too hard. Some guys run a 14T on the freeway and just rev it out. Some guys go with a 45T rear sprocket instead of the stock 43T and switch between a 16T and 14T front depending on the ride (highway or dirt). I found that for the fire-roading I just did the stock 15/43 was fine, didn't even need to slip the clutch much, just kept it moving. How much you weigh and how much gear/luggage you haul is definitely a factor in this decision. There's a FAQ worth reading. The jist of it is, spend money on suspension and leave the engine alone. Having said that I was seriously considering the 685 kit from Cary. Reports say that the engine is Much Smoother with the forged piston. I just rebuilt my engine with new doo parts and a used head from an '05 and the engine was much smoother just doing the doo and valves. Plus, I'm getting 53mpg with the stock setup (pipe, jets, airbox, everything stock) and don't want to mess that number up. Doing the L-mod and upjetting will get you a few more horsepower but mileage will drop down to about 48mpg. One guy reports a 20% increase in power with the L-mod and bigger jets. Let's see, a KLR stock is about 36bhp at the rear wheel, so that would be about a 7bhp increase, from 36bhp to 43bhp on a 420lb. bike. You're still not going to give an R6 a run for its money until you find some very tight twisties and - you just gave up 5mpg. If you're constantly wanting to get from 0-60mph in under 4 seconds or go faster than 85mph you're probably on the wrong bike. My stock KLR seems to be happier at 5k rpm and 72mph than going much faster than that. Oil consumption reportedly goes up at prolonged revs higher than 5k. http://www.bigcee.com/klr650faq.html

But I have to ask, is the 72mph ACTUAL or what your speedometer says, which is probably at least 5 mph off, unless you fixed it somehow. I'm about to get a new front tire. Is getting a larger one the best way to get closer to actual mph? I have switched between 14T, 15T and 16T but the 15T is what I have on my bike know. It may stay on. However, when I took a long trip last spring, much of which was on the Interstate, the 16T was really nice. Vibration and engine noise was down. I put the 14T on when I got into the mountains and had I not done that it would have been a disaster. I suppose when one has the 16T on he really needs to be careful not to lug, which can easily be done by hitting a lower gear. At the risk of being seen as rambling I have one more comment, uah, question. Why are the speedometers off -- showing that you are going faster than you really are? Could it be that it helps keep the speed down and therefore results in less accidents? rw TotalHealth.bz Focus On Truth --------------------------------- Be a better friend, newshound, and know-it-all with Yahoo!

I also found the speedometer on my 07 to read 7% high. I expect that error will increase to as much as 10% as the tire wears. I,m not sure if you can get a 21" tire with a outer circumference 7- 10% over stock. If you know of one let me know. You could dissasemble the speedometer and bend the needle back, so to be accurate at 60mph. This would reduce the error to less than 2 mph in the 40 - 80 mph range.

I just put one of those label maker stickers on mine: Reads, "This is just a suggestion." ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!
