1st gear "jump"...?

I just got my first KLR, ('05, stock, with 2200 miles on it) which
also happens to be my first motorcycle. After a few hundred miles, I'm
finally feeling comfortable on it and I absloutely love it! What a
great machine!
I have noticed something, though, and I'm not sure if it is normal
behavior for this bike or motorcycles in general: when I'm stopped,
idling in neutral with clutch pulled all the way in, and shift into
first gear, the bike jumps a little bit. It's nothing serious, just a
small movement, but it is noticeable.
Is this normal? If it is abnormal, I'd like to fix it early. I plan
on having this bike for a long time, and I want to keep it in the best
shape possible.
Thank you all very much for your input. Go KLRs!!!

You need to adjust your clutch. Probably best to do it below although you
can do a fine adjustment at the lever Directions should be in the owners
manual.

Couple questions to help answer yours.
Does it do it when you first get ready to ride,when the bike is not
quite warmed up?
How much freeplay do you have in the lever.
Many of our KLRs require a few revs with the clutch in, when gettin
it warmed up to ride.
This prevents a big crack goin into first, from neutral, cuz the
clutch plates are kinda stuck together.
Bogdan nailed it if you have over an inch of freeplay in the lever.
Good luck and keep us posted,
Rod

While that is true in his case, I'll note for further reference that if
the bike has been sitting for a while with the clutch out and you pull the
clutch lever and kick it into gear, it is normal for the bike to "jump" a
little. That is because the clutch plates have a bit of "stiction" that is
especially noticable when they've been sucking up to each other for a
while. All multi-plate clutches do that, because there's nothing to force
the clutch plates apart other than their normal warp (just as there's
nothing to force your front disks apart other than the normal warp of the
disk). Thus if they've been sitting up long enough to "stick" to each
other, you'll get that little "jump" as the engine kicks them loose from
their embrace.
You'll notice more stiction with 20w50 than with 10w40 oil. Unless you
live in Death Valley or normal summertime temperatures in your area are
above 90 degrees, you probably want to just stick with 10w40 oil anyhow,
it'll give you better lubrication during the very vital warm-up period.
Synthetics will virtually eliminate stiction, but they cost a bundle and
it's unclear that they'll result in longer engine life for a KLR engine.

I have a 2001 with 1700 miles on it that does this after sitting for more than a day. In fact, it snubs the engine when I shift into first gear. I changed oil but have not seen any change. I will try the clutch adjustment when it stops raining here (Green Bay, WI).
I have just received the service manuals that I purchased on eBay but have not had time to look at them at all.

1st gear "jump"...?

Thank you everyone for your qiuck responses to my query! This KLR
group is a great thing!
The concensus is, then, that a little jump when dropping into first,
especially when the engine is cold, and especially when heavier oils
are used, is normal. I did use a heavier oil (15w40 semi-synth)
this last oil change. I live in Tucson, and it's going to be hot as
blazes in no time, so I figured I'd give the bike a little thicker
oil to combat the searing desert temperatures.
Thanks again!
I look forward to picking the collective KLR brain more and more

Normal but not good. As I recall, Elden who has inspected many klr trannies
stated that the first gear is often chipped. You should pull in the clutch
and blip the throttle before shifting into first when the engine is cold;
that frees the clutch plates and allows a smooth entry into gear. The shift
into first should be smooth when the engine is warm. Again, if it's not
adjust the clutch cable.

That's helpful info, thanks. I tried "blipping" the throttle and
working the clutch a few times this morning, but it still gave me
the clunk. It does subside as soon as the engine is warm, though.
I am running a thicker (15w40) oil, in aniticipation of the blast
furnace of a Tucson summer that is inevitably approaching.
We have had some semi-cool (for Tucson) mornings (low 50s!) lately,
though, which could account for some stickier than normal clutch
plates, no? Sorry all you cold weather folk, don't mean to rub it
in! But you'll be laughing soon enough, when the KLR and I are
panting like tired dogs as we suffer through blazing asphalt and
stoplights to get up into the higher elevations for some
relief...thank God for the mountains!

Or with the engine off, put the bike into first, pull in the clutch, and
try to move the bike. If the bike's been sitting a while, you'll have to
give it a pretty good "bump" to unstick the clutch.
Then get on and start it up and ride.

Every bike I've owned (a Yamaha, a Triumph, and now my KLR) has clunked
hard into first gear at the first shift in the morning. I wouldn't
worry about it.

Actually, 40-weight oils are the thinner ones recommended by the
owner's manual. You might want to consider 50-weight oils for
summertime in your neck of the woods. (Mobil 1 15W-50 seems to be
available in most Wal-Marts and it does a good job. I haven't used any
non-synthetic 50-weight oils, though, so I can't make a recommendation
if you prefer dead dinos.)
