I am trying to lower the rpms. It seems like I go thru the gears before I get out of the driveway. I live on the East coast of NC therefore the terrain is flat. I use the bike for short rides and enjoy riding speeds around 50 -55. I am thinking of changing the sprockets to 16/40 to obtain taller gears but I am not sure if the bike will be hard to get going in first.Did not say but I am assumming you want to lower the RPM's Go one tooth bigger on front. Stock is 15 so you want a 16.It is a noticable change in gearing. Some like higher gearing some do not. Depends on a bunch of variables so you must try it for yourself. Good news is the cost is really low. 20 bucks or so and it is easy to do.
I like this plan. Ride a 17 on the I81 to the track. Put a 15 on for better drives out of the turns when I get there.Last summer I rode to Colorado for some off roading action, then to Montana for some mountain work, and then back to Houston to home for some honey -do action.. I carry a 14T 15T 16T and a 17T and change when riding conditions change. I run a stock chain and stock rear sprocket. Change over takes about 20min and some hand cleaner then back on the road. Lets you get the best out of the KLR. Just my 2cents Bye
