hey guys is it normal for the bike to lurch forward when going from neutral to first? also yesterday i was having trouble shifting into second every once in a while, it was like hard on my foot to shift.
 
How old is your clutch cable. It could just need to be adjusted. Some of the more knowlegable people might have more on your problem.
 
What bike do you have? I'm going through the same issue and in fact I think I figured it out (will know tonight). You should have a another cover on top your sprocket cover. Loosen the screw and locknut there about 3 turns, loosen the locknut up by the clutch cable at the handlebar, turn the screw down in the sprocket cover until you meet resistance and tighten the locknut there. Adjust the clutch cable at the top to what the book says (I think mine says about 2-4mm of play).

Put it in your signature, so we don't have to guess and give you the wrong answer

Your bike does not have the external adjuster as above. The adjustment is on top of the crankcase, on the right side

If you suddenly have more free play at the lever, your cable is breaking

I looked at the hand lever and it looks like i still have about half of the adjuster that i can still pull out to bring in the arm going to the clutch.
 
i appreciate the thought at least, im hoping just bringing out the adjuster will tighten up the arm above the case and bringing it in making the clutch engage better. If not i noticed a bolt on the other side of the arm that i could prob adjust too to make its not grinding when i go into first out of neutral.
 
The one off of Cliff's site is for an 82, and the same year 550 doesnt seem to match up to the 850 all that much
 
Cliff will be able to tell you more but he's got an 80 850. I don't think things will have changed much so check out the one on the top of his site.
 
Let me chime in here before you go too far. Questions first: How old is your oil? (important) Do you have any gas in your oil? How long are you allowing for warm up? very important)
The reason I ask these questions is if your oil is too cold, the clutch plates stick, causing the exact symptoms you describe. Gas in the oil will also do it, and dirty old oil makes the plates stickier also. Any or all of the above could be causing your problems.
 
Dude, just replace your clutch cable and throttle cable anyways.

Probably the cheapest underrated mod you could do!


Good thing I replaced my clutch line, because it was Literally hanging on by just a few strands!!!

I can't believe that I kept putting it off!
I "assumed" my clutch was OK....because it worked, just like everyone else!

That's the stupidest thing you can do with these bikes....is Assume!

My clutch feels awesome, and throttle, brand new!

You've correctly adjusted your clutch cable and it's still dragging!:-\\\

The problem lies within the clutch design of the '79 850's.

The oil supply into the clutch basket is excessive, with insufficient outlet holes. The problem is further exasperated when owners run 20w50, instead of the recommended 10w40.

Suzuki issued a service bulletin listing a replacement release rack with a smaller diameter oil hole to reduce the flow through the clutch basket. This caused another problem in that the increased pressure upstream now pushed oil past the clutch lever pivot seal. Their response to this was to modify the supply passage that feeds the oil from the engine case to the release rack. They fitted a restriction jet to the later models.

I have have done these mods to my engine, plus drilled extra holes at the rear of the basket, and the front pressure disc.

Was it worth doing? YES.

I run only 10w40 fully synthetic oil, changed regularly. I find that if I fill the engine to the full mark, I do get some minor drag, when the engine is cold. So, I run mine between 1/2 and the low mark, I have no drag at all. I allow a 2-3 minute warm up before riding off. Very important during our winter months.;)
 
i readjusted the cable and it doesnt seem to be doing it near as bad. Also to answer a few of the questions on asked, brand new oil. Im changing my gearbox and shaft oil tomorrow. Im still getting a bit of a lurch forward when i go from neutral to first. However it is extremely minor.
 
Tighten the cable until there is only a small amount of freeplay at the lever. You can adjust it at the lever or at the engine case, doesn't matter. This is a really basic motorcycle maintenance task. Do you have a manual and take care of other maintenance like adjusting the valves?
