I purchased a 2016 KLR this past week with 436 miles on the clock. First of all I previously owned a 2015 from new I purchased about this time 2 years ago but unfortunately it was backed over by a truck and was totaled at around 1000 miles.
I have a concern about vibration, as long as I do not ride over 55 mph it is smooth, at around 60 I am getting vibes in the seat and pegs, at 65 the bike feels like it is going to maybe not fly apart but shaky. The 2015 never felt like this and was smooth. I bought the bike to ride around on back roads and not for the slab but would like to run a little faster at times.
Would a 16/17 tooth sprocket help with the above concern. I also feel like I am having to shift too soon out of all the gears. I am not planning on riding on any dirt or gravel.
Any feedback would be greatly appreciated.
I'll suggest two major possibilities of your vibration on so new of bike.
#1, Too Tight of final Drive Chain!
The drive chain needs to be loose enough to be able to Lift the bottom run Up to Touch the rearward tip
of the rubber underslider on the swingarm.
#2, Too Loose of engine balancer chain! aka, the Doo-Hickey.
I have encountered a couple of newer KLR650's which the doo-hickey locking bolt was left loose by someone, possibly even the factory!
I urge people to remove the 2 plastic access plugs on the Left engine cover and using a 19mm socket to turn the engine CCW until they see the 'lazy T' mark on the rim of the flywheel.
Then remove the Rubber plug Under the Left engine cover (may have to loosen plastic skid plate) and loosen the 8mm locking bolt Two Turns. (If that locking bolt is/was already loose, that means the Adjuster Spring was the only thing trying to keep the balancer chain in time. And it can't, at higher rpm
Re-snug that doo-hickey adjuster locking bolt to 70-80 INCH Pounds, or just snug on a 3 inch wrench.
Standard sprockets are 15-43 and the engine will turn about 4000rpm at 55-58mph indicated. 6000rpm crowds 85-90mph and I have ridden over 80,000 miles with that ratio only. (Best overall compromise for me & my location.)
