Default 91 suzuki katana 600

when I get on the throttle around 8k rpm it just revs like i pull in the clutch or something. Im a fairly new rider and havent had any probs with it like this so far. If i gradually increase my rpms it doesnt seem to do this. what is the prob. Could my chain be to loose or something. Help me out...Thanks! No other driving issues that I can notice besides that.

The Clutch kits are pretty straight forward if you are mechanically inclined. If it's you're first time inside I would suggest having a more knowledgable friend be there for the assist.

What kind of oil is in it ?
If you don't know, a change......using actual motorcycle oil might help.

Is there any slack in the clutch cable ?
There should be a tiny bit.

What's the redline on this model ?
The engine and tranny will last longer if you stay away from it a bit.

P.S. Chains don't "slip".

+1 on the oil, that was my thought is it having automotive not 4stroke oil. Chains can jump the sprocket, but the RPM's wont jump, you will feel the thump from underneith like your seat is coming off the bike.

Did you use oil labeled for use in motorcycles?

Oil made for cars has an anti-friction additive that doesn't belong in motorcycles. The clutch on your bike is "wet," it is completely oiled at all times. Motorcycle oils are designed to lubricate without causing clutch slip, which sounds like what you have. If you used the wrong oil, change it and you should be ok after a while. Might even change it again after 500-1000 miles.

If you don't think oil is the problem, the clutch may need adjustment. $100 or so at a good shop.

And if it is a cable actuated clutch, 30 seconds and zero dollars in your driveway. There should be a tiny bit of slack in the cable and there is a simple adjustment for that.

If the automotive oil I bought didn't have the friction modifiers is it still good to use? Every time I look up an oil thread I get a headache.

If the oil is labeled SAE "CE," "CF," or "CD," but does not have the API label "AMF", and the oil is not intended for use in the 48-contiguous states, then it's probably not a good idea to use it on odd-numbered days in temperatures above 28 C.

Just buy the damn motorcycle oil. They sell it at WalMart.
