Question A lot of vibration above 4000 rpm

Since I'm fairly new to riding and only have about 1100 miles on my 2009 klr, I was wondering how much vibration is there usually at 4000+ rpms. It seems like a lot.

Also, I was wondering what peoples normal shift rpm is....mine seems to be the 3000 mark....slightly below for 1 & 2, and slighlty above for 4 & 5

I just hit 3000 on my 09 and it doesn't have a whole lot of vibration above 4000 rpm. It does increase a little on the pegs though. I haven't paid a lick of attention to when I shift though.....I just listen for what feels right for where I'm at.

I don't have problem with vibration; perhaps it's something you just get used to on the KLR.

Check your chain for proper adjustment and adjust the doo.

I shift at 4500 from 2 through 4, 5000 for 1-2. Usually run at about 4000-4500 rpm in any given gear.

I have an 09 also, I think the vibration is very low for a one cylinder bike and what vibration there is I cut back by putting a 16 tooth sprocket on front that dropped the rpm down and took away a lot of the buzz at highway speeds..I ride and 05 Concouse the KLR is no inline 4 cylinder for smooth and I do get more vibration over 4000 rpm's on KLR..As far as shifting there are no hard and fast rules,other than don't lug it. Things change starting out or riding up hill will take more rpm then running on the flat or down a hill...Just like a car the more rpm's the more speed the more fuel.. It sounds like you have a good idea of what is going on and with time you will be telling us how it's done.. Ride on grasshoper and may your crashes be few

Ahhh, that's how you guys get 60 MPG !!!

Anything less than 3000 to me is lugging it. Mine seems to run best between 3000 and 6 - 6500 anything more and it tapers off fast. The vibes are there always being a "thumper".

Gray-haired riders don’t get that way from pure luck.

anything above 3500rpms in any gear below 5th sounds like its about to explode.....unless its suposed to sound that way. Plus I'm usually at the speed which the manual recomends shifting when I'm at or around 3000 rpms.

60?.....I'm still pulling about 40mpg. But I figured it was becuase of my weight (295) and the fact I ride mainly streets.

Nah, Just joking because i've seen the claims and wondered how anyone got that kind of mileage! I tip at around 220 and DOG mine mercilessly and get about the same as you.

I agree with flash here. I don't like to run it much under 3500 as it seems "luggy".

First gear on the KLR is stupid-tall. The 1-2 shift drops 1500 rpm, so shifting at 5000 puts me in second at 3500 and feels right.

All the other shifts drop about 1000 rpm, so shifting at 4500 puts me in the 3500 range, and I move up to 4000 which I find coincides with many speed limits with stock gearing.

Normal operating range, then, is 3500 to 5500, though it has seen 8000 rpm. Booyah!

If yours sounds like it wants to explode (and it's not 'just you') perhaps your balancer chain needs to be adjusted.

Pop the little rubber cover off the lower left side of the case and get an 8mm socket on the bolt. Turn it out one turn. Rap on the head of the ratchet handle with a screwdriver handle to help jiggle things a bit (that lets the lever move and adjust the chain). Then turn the handle back one turn to torque things back up. Understand, that bolt doesn't need, nor can the doo stand, a lot of torque. Just snug is all it needs to be.

If the engine is not noticeably quieter after that (and it's not 'just you') then you may have a doo spring that has given up and is not tensioning the lever. Very common on the Gen2s, and indicative of a need to dive in there and do the doo.

Gas mileage - I slab in at about 240 and pretty regularly turn in 47 mpg +/- 2.

The manual also talks about the sixth gear, which I have never been able to find...

If you go with the 16 tooth the mileage would be 50 EZ I was 38-48 with the 15 tooth and now 40 when I'm running it hard and 58 under speeds of 65 and shifts at around 3500+ - and no real loss of torque...I'm 210 lb's and maybe 30 + lb's of junk in my hard bags...I will admit I'm 50 + and a mechanic so I run my stuff with in it's mechanical limits. I'm shore there are riders that push harder then this old man...
