what model bike?
I see your profile, but that does not mean that is the bike you are speaking of.

a slipping clutch can result from a cable that is not releasing all the way,

or from having used an oil with Friction Modifiers in it.

does the clutch also slip if you apply wide open throttle in other gears, or only just as you are taking off from a stop?

my first solution would be to pour in 4 oz of Sea Foam in the crankcase and ride it for 100 miles or so.... give it a chance to dissolve anything on the clutch plates.

drain oil, new filter, and fill with an oil that does NOT have any friction modifiers in it, and try again.

Oh, OK, that's going to be your problem, then. Car oil has friction modifiers in it - special additives that makes the oil really slippery. When you put that oil into an engine that has a wet clutch, the clutch plates then slip against one another, like you're experiencing.

I would add a whole can of Seafoam, which has solvent properties to the crankcase. It will thin the oil, so be gentle - ride the bike gently for around 100 miles or so, then drain that oil and refill with new motorcycle oil. There's a good chance that will solve the problem.

If it doesn't, you may be looking at a new clutch, to replace the friction material.

do as WingAdmin suggested,

I said 4 oz but I think he is more correct, you need a lot of solvent to get rid of the friction modifiers.

If you pull the dip stick, does the oil smell burnt ???

Per the Owner's Manual .... never, ever add an additive to the oil. I'm currently doing a transmission repair because someone did. It's a nearly new 2003 with 4,700 miles on the ODM. Here is a picture of the additive. If it was oil, it would drip away, the black stuff will not do that. In this case it is probably ZDDP.

If the oil might be at fault, the best oil to try is Honda's GN-4. I just advised someone else who's been using Honda's semi blend to switch to GN-4. When I test rode his bike, his clutch would grab towards the very end of the clutch lever travel. After changing to GN-4, his clutch grab was more normal. Also, verify that the clutch m/c is not over filled. The fluid level should not be above the fill level under the cap. The other thing that can cause clutch slipping is dirty clutch fluid that is plugging return ports in the clutch m/c. Is the fluid under the m/c cap clean and clean ???

Then check the clutch fluid and replace it if dirty. If none of that helps, then it probably time for a new clutch.

Is your clutch lever moving freely ??? When you grab the end of it, there should be no more then maybe 3/8" of up/down movement. The clutch lever's bushing, pivot pin, and brass bushing should be cleaned, lubed, and inspected every 8,000 miles. Be sure that the rubber boot that protects the push-rod at the back of the m/c is not torn.
