Will oil change affect clutch?

Usually you will notice some slippage when they wear out, you may have some grooves worn in your basket and/or hub, perhaps the plates are sticking “out” of the grooves and not disengaging when they should.
If you replace the clutch check for grooves, and replace the springs as well. Hope this helps.

I first tried full-synth (5W40) too, and i notice the same feeling about the clutch ; not slipping at all, but very short and violent.
The reason of this is the reduced viscosity of the base oils used to make synth oils. Now i swiched to a semi synthetic ester based 15W40. And this feels a lot more progressive.
Watch out for expensive 'Motorcycle Oils', in fact these oils are often fomulations used in automotive oils a few years ago, altough they are claming these oils have a limited amount of friction modifying additives to avoid the clutch to slip. BULLSHIT
Try a good quality automotive 10W40 oil, this will work fine.
DON'T BELIEVE THE HYPE.
(If anybody had a slipping clutch because of using an automotive oil, i would be glad to hear his story)

With the change in passenger car oils to API SJ came an increase in friction
modifiers and a
decrease in zinc and phosphorus, addressing concerns with fuel economy and
converter/pollution issues. For motorcycles, the additional friction modifiers
can affect wet
clutch performance, and motorcycle engines appreciate a higher level of the
ingredients of zinc and phosphorus.

It was a bummer, cause the clutch was not very old (few months), and having to replce the friction plates to fix the problem didnt go down too well.
I know we're talking different calibres of machine - but the technology is the same.
PS. the automotive oil work perfectly well as bar oil on the chainsaw!!

You are opening up a can of worms on this one! You will start up the Mobil 1 discussion again!
I use Mobil 1 15w-50 with ZERO problems.

So the good news is I blamed my friend, dodged any further questions from the wife and have a date with a new clutch kit, a clean garage, and maybe a Canandian Blue (necter of the gods) to keep me company.
BTW: Which aftermarket clutch kit should I buy?
Thanks for putting up with the rambling. As a poet, I make a heck of a mechanic. And thats not saying much, I am no mechanic.

I agree with "The Hick" three years is a long time, consider yourself lucky. You'll pay $180 for OEM or 1/2 that for a White Brothers replacement.

At the beginging of this riding year I changed oil and cleaned the oil filter. The last change I used Golden Spectro synthetic and this time I used Honda's (Sorry, got talked into it) synthetic oil. I noticed my clutch is not engaging until is is almost all the way out. I have adjusted the cables and I still don't have much room. I did not notice this much of a problem at the end of last year so I was wondering if the oil change could have made things worse. Maybe after 3 years it is time to put a new clutch in. I ride more motocross than anything else. I have not had time to pull some plates and measure them. This whole job, wife, and two kids is putting a real damper on my moto rebel lifestyle! Honey, if you read this I am just kidding.(think she bought it?) Anyway, thanks to anyone who may have an insight.
