Bike "jumps" when shifting from neutral to first

Hi. When I put my 83 maxim 750 into 1st while standing the bike tries to "jump" forward a bit even with the clutch fully depressed. Is this an issue?

 

It could be that your clutch is miss adjusted (very common issue), but a fair amount of clunk in that particular shift is normal.

 

It may just be a clutch adjustment, or it may be severly worn clutch clutch plates. Try adjusting the cable first and see if that helps. If not you may be looking at a new clutch.

 

I have the same problem. Only to first though. It only does it going into second on up if she's not completely warm.
So how do you adjust the clutch cable? Its not like the throttle cable

There is a series of nuts on a threaded end down where it connects the arm by your right foot.

 

There should also be an adjuster at the handlebar end.

The "clunk" going into gear is caused by clutch drag. Even a perfectly adjusted clutch will produce some drag, resulting in the "clunk" especially when cold. An EXTREME "clunk" or a persistent one does indicate the clutch is dragging and needs adjusting.

Worn plates won't cause drag; they'll cause slippage.

 

If your idle is too high, you'll also see this behavior.

 

There was a post on here about clutch adjustment. I can't remember who posted it. I followed it to a T and it worked like a charm.
