Try it....it might make a difference.
Yup, 10W-40 in my little Monster is what they call for. Looking forward to your results. Let me know if you need a dry place to work on it, you're welcome to come over if you need to.

OK - So my only input is from owning a 95 900M Monster...
I ran into some clutch problems and the it was from the bearing running from the slave to the clutch basket. If that bearing seizes (not uncommon) the shaft that pushes on the clutch will SPIN and cause some problems in clutch accusation...
Not sure if the 696 Monster is the same system or not -

Just a thought...

Add heat, the fluid expands, extending your clutch slave, causing slippage.

This was my first thought or a plugged return hole in the master cylinder. Some people try and adjust them too tight and have an issue.

If I understand the bearing issue correctly, this would seam to be lubrication related. I can see that potentially happening on a dry clutch, but would a wet clutch (as in Susan's case) be susceptible as well?

Not knowing much about this subject?
But this sounds very plausible.
No to figure out how to fix that the free and easy way??

First thing is see if no 'bleed back' is the issue. With brakes that suddenly start to tighten up when moving and while the condition exists crack the bleeder and see if it goes away. Either loosening up if it is brakes or suddenly hooking up for clutch. The adjustable levers I have worked on you remove the lever and there is an adjustable screw/bolt with a lock nut to move it in and out.

Still with the clutch issue ey? Jim makes a great suggestion, rebuild both the slave and master cylinders. I'd probably replace the line too, as it may have developed a small enough leak that the air is getting into the system. This should be relatively cheap and easy to do.

You could also try the product of the slightly more reliable Italian brand that brings more of everything to the table too, including a cable clutch.

Excuse me, but this is a technical issue area... Non-bike leg humping is strictly prohibited.

Not that we wouldn't mind seeing said pictures in the NWS section, but only if April is wearing something shall we say: Exciting!

Soooooo after many cold and rainy days I FINALLY got to take her out and test the clutch. I am happy to say she runs like a champ now I just spent an hour stuck in Friday traffic inching along so she was thoroughly tested, as was my patience. I finally just went around everyone and cut in front like a total jerk, but fuck it.

Apparently there is a known issue with moisture getting trapped in the slave cylinder. Whenever I would stop the heat of the engine would cause the moisture to boil and expand mimicking air in the clutch lines. I ran a half of bottle of DOT4 through her and changed the oil to 10/40. She now pulls like a little beast and has no problem with over heating and getting "stuck in neutral".

Thanks everyone for your input. Now on to a great summer of riding
