The clutch on my 1995 suziki vs 800 slips under power,it disengages

You probably made the mistake of putting synthetic oil or STP in it.
It wasn't designed for that. You can put the extra strong clutch springs in if your man enough to squeeze them.

Keep the bike upright and place the handlebars straight. Check the clutch fluid level in the reservoir. If it's below the lower mark, take the cap off and fill it to the upper level. Use D.O.T. 3 or 4 brake fluid. If this doesn't solve the problem you may have air bubbles in the line or dirty fluid. If so, make sure the reservoir is at the top level and replace the cap and tighten it back up. Remove the secondary gear cover.(just ahead of the driveshaft) Attach a pipe or hose to the bleeder valve and run the other end into a pan or something similiar so you don't get fluid everywhere.Squeeze and release the clutch lever several times in rapid succession, and squeeze the lever fully without releasing it.Loosen the bleeder valve by turninmg it a quarter of a turn so that the fluid runs into the resepticle; this will remove the tension of the clutch lever causing it to touch the handlebar grip. Then,close the valve,pump and squeeze the lever, and open the valve again. Do this as many times as needed to get the air out of the system and nothing but clear brake fluid running through the line You may have to add fluid to the reservoir during this process. When the air bubbles are gone and the fluid is running clear, top off the reservoir to the upper level. Also, you may know that brake fluid will peel the paint off of your paint job so be careful not to get any on the painted surfaces.
If all of this fails, then you probably need new clutches but most likely not. I have an '86 model (same bike) and it still has the original clutches. Hope this helps; John
