Clutch sticks at first startup

This has happened usually after the bike sits for a couple of days, I start the bike in neutral, pull in the clutch lever and when I shift into first gear the bike lunges forward like the clutch isn't in. If I try to start the bike in gear with the clutch in the bike also lunges forward. After the first or second time it seems to engage. Any ideas???

A characteristic of "wet" clutches; cold oil forms some adhesion between clutch disks.

Several countermeasures; among them, hold brake on, increase rpm in neutral, then shift into gear. A momentary lurch occurs before the clutch disk bond is broken, a higher rpm prevents engine stalling during this brief incident.

Then, ride on!

Welcome to the world of wet clutches. They do this to some degree or another. Some of the riders claim their choice of engine oil affects the clutch plate stickiness that causes this lurch you describe.

Force of habit now, developed from a few dumps and bumps, if a bike with a wet clutch has been sitting for more than a few days, I'll grab the clutch lever, pull it the bar, and let go of it before I start it IN NEUTRAL...then blip the throttle a time or two, grab the front brake lever, and drop it into first. Another simpler method is to rock the bike back in forth a bit in gear, just enough to break the clutch plates free.

What oil are you using?

Weird.. My BMW airhead never does it.. (It's got a dry clutch)

I don't even think about doing this.. I just rock the bike while pulling in the clutch. Just a foot or two and it's not an issue.. Pretty good lurch if you don't, though.

Mine does it too. It's the nature of the beast. Just pull in the clutch and rock the bike a few times while it's in gear, that will free it up.

glad someone asked this question. i'm sure there were quite a few of us with the same issue. i was getting a bit tired of looking like a tool in front of my neighbours after making an obnoxious scene starting mine with the 98dB jardine exhaust, then stalling it when i go to put it in gear. so thanks!

I think all my bikes for the last 30 years have done it.
Didn't even notice on the KLR. Nature of the wet beast.
