I use the Honda oil which could have sworn it's synthetic.

i would use a honda synthetic blend only, the other will be too slick for the wet clutch

A little article from Amsoil below. I personally like to use the Honda oils also though.

Many people have the perception that since synthetics are more slippery than petroleum oils (which simple don't reduce friction as well), that wet clutch packs in either their automotive automatic transmission or motorcycle transmission will slip when using "super slippery synthetics". Synthetic oil is no more "slippery" than petroleum oil. It simply has a more uniform molecular structure which reduces frictional resistance better than the irregular shape and size molecular structure of a petroleum oil.

Look at it this way. Wet sandpaper removes paint as well as dry sandpaper does. The slipperiness of the water does not impede the sandpaper's ability to function. The same applies to the "slipperiness" of synthetic lubes in wet clutches.

If used dry, the sandpaper is soon filled with paint and no longer works- it slips across the surface without grasping the surface. If kept clean and free of paint, it continues to work. The lubricating/cleaning solution used can be water, soap, oil or any other liquid. The liquid's slipperiness does not affect the performance of the sandpaper.

It is simply not an issue. However, just as rinsing the sandpaper keeps it cleaner longer so it functions better longer, so the synthetic lubricant keeps wet clutch plates cleaner longer so they function better.

AMSOIL synthetic lubricants will prevent deposit buildup on clutch plates, therefore keeping the face clean and able to do its job in preventing slippage.

And, since synthetics are superior cooling agents to conventional petroleum lubes, using synthetics will help wet clutches last longer, too.

Petroleum oils have low resistance to heat and allow varnish and glaze to form on clutch plates, which eventually leads to slippage and increased heat generation and eventually failure of the clutch pack.

Also, AMSOIL motorcycle oils are specifically formulated without any friction modifiers for compatibility with wet clutch packs. AMSOIL ATF lubricants are also designed with specific coefficient of friction values to meet the requirements of each and every specification that it not only meets, but far exceeds.

Now you know the facts. The next time your buddy mentions this as a potential issue, you can explain to him exactly why it is simply not an issue

That is what I was looking for Friction Modifiers, make sure it has not been added to the oil you are using.

I use Silkolene semi-synthetic. Change oil and air filter after every ride. Oil is cheaper than replacing metal. That's why my 04 450r is on original piston and clutch after 6 years of ownership.

Honda HP4 10w30 in the winter 20w50 in the summer. Been using it in all of my Hondas for years. I also change the oil and filter after almost every time out. After 12 years, my XR600 is still on the original piston and lower end. Made a few mods to the top end about 10 years ago but nothing since. Oil is cheap insurance.:hey:
