I've had a lot of bikes and find the klx to be the easiest bike to stall. It has such a small "catch point" that my fiancee stalls it all the time at stop signs and lights? I even dropped to a 13t sprocket. Is this typical? The bike is a 2007 with around 600 miles on it.

 

What's your idle set at?

 

Clutch cable/lever action smooth/lubed? Freeplay correct?

 

I've ridden tons of trail and race type dirt bikes. When set up properly...correct jetting, etc...the KLX is not an easy bike to stall. It has a decent flywheel and a really low end, torquey powerband. No disrespect, but I'd suspect the fact that you mention it's a lady that's having this problem. Now, I might be totally wrong, and she might be women's class A enduro rider...but your description sounds like a rider who doesn't have a smooth clutch and throttle technique. On the other hand, your particular KLX may be too lean or have another issue causing a touchy throttle/clutch engagement, but it's not the general nature of the bike. Being an '07, do you know its history, mods, or any problems?

 

The less power a bike has the easier it will stall, stock this bike has 17hp. Gearing plays a role to, but highway gearing and minumal power output make for a bike that could be prone to stall. That being said I've never noticed it at all.

 

Usually if the rpms go below 950 it stalls

 

For what it's worth.
My son was just learning to ride this spring and he was stalling his 2007 klx250s once in a while, but now that he has some experience under his belt he seldom stalls it anymore. Confidence in giving it a little more throttle I think is what helps.

 

In my experience, I always found the KLX pretty much stall-proof. Nothing like any of the little 2-stroke GP replica bikes some of my friends have owned over the years!

Is it stalling as the clutch is being released (which may indicate operator error)? Or when the clutch is disengaged or after the clutch has engaged and revs are building (which may indicate a carburation problem)?

Certainly when cold, the bike can be expected to hesitate a little...

 

It is not normal for the KLX to be easier to stall than other bikes. I don't stall this bike any more than the xr400 and 500s I raced over the years. I love the low idle thump too. Really, I about never stall it.

You've got a skill problem or a problem with the tune.

 

I think she really just needs more practice. I raised the idle to 1400 and it helped a little. I dont ride it because i weigh too much for it with her lowering link.
