A noob question to make you guys roll on the floor and soil your shorts-
 
-As some of you folks know, I just got a 07 640A. Took it for a spin and I was all smiles. :1drink I have ridden in the past, but have never owned a bike. The bike runs flawlessly. But I experienced a little weirdness with the shifter. Obviously user error. But I'm curious. The bike is started and allowed to warm up. Sometimes I have a little difficulty getting the bike into 1st. Not sure, but it appears that if I let the clutch out just a bit, the bike will gently go into 1st and all is fine. Is this normal? Either I read this before, or I dreamed it up. But is there a sweat spot on the clutch? Yes-I cruised through the index. LOL.

I don't know anything about the 640, but I do know that new bikes tend to shift oddly. If you aren't mashing it into gear I wouldn't worry about it until you get some miles racked up.

+1 on give it some time to settle in. A similar observation with KTM's when they are new is trying to find neutral with the bike running at a dead stop.

Is it always like that? When moving or stopped?

It's not uncommon to have the gears in just the right position that the trans can't shift when the vehicle is not moving and the clutch is pulled in in particular on a tight trans. Letting the clutch out a bit will spin the trans shafts around and allow it to shift.

Thanks guys for the responses. They all make sense. I didn't want to break my new toy.:rofl Master Braindead0-seams like it happens only at a complete stop. If I let the clutch out just a bit, then it goes into gear nice and easy. No problem with the rest of the gears.

Sounds perfectly normal. You can also try moving the bike forward/backward a bit (assuming it's in 2nd gear). Best bet is to downshift before stopping, that should always work.

It may clear up a bit over time as you break it in.

If you can engage first gear without killing idling engine its ok :evil

Try any old Moto Guzzi... KTM clutch/transmission is silk smooth after that :rofl

My guzzi is like shifting a tractor. It makes for some interesting practices while ripping ass up a canyon road.

As for the 640 just be nice to it. I have seen guys try to mash gears on bikes and it is just wrong. If you are needing to stomp it you are doing something wrong. With a little time it should break in nicely.

Make sure the free play in the clutch cable is adjusted correctly.....the cables stretch a little after break in..

If you are talking about the first time you drop it into first gear after it has been started cold and allowed to warm up; it is very typical for the engagement to be difficult and jerky due to the fact that the clutch plates are sort of stuck together with cold oil.

Getting into neutral, or into first, after you have been riding is never super smooth on a 640 but it should be nothing like the first shift of the day.

Hey joe,

My 03 has always been like that... I got so used to it that I don't even realize that I am letting out the clutch lever a tad to slip it into gear. Never got a satisfying answer as to why this happens. I thought perhaps something was misadjusted, but can the clutch lever open the clutch too far? Nah, I doubt it. Maybe it is a manufacturing "defect". :dunno

Seikkailu_R 01-14-2008 05:12 PM

Maybe that sweep spot is just where friction in clutch plates overcome friction in transmission. Gears start spinning slowly, helping engage gear.
But plates start slip when gear is engaged.

If clutch is fully disengaged, gears stop?
Sometimes dogs match holes, sometimes not.

Yup, they almost all do that. At least the later models anyhow. Lots of agreement over on SMJ.

Get it in gear then give it hell!

Sorry Joe but none of these guys are telling you what is really wrong with your bike! When I had my LC4 and it did the exact same thing it ended up being the Kanueter Valve in the shifting mechanism. Its located right under the inner shift linkage below the chain line! Fix that and your shifting problems will be over! :thumbup
