SOURCE: vz800 stalls when put in gear

Have a look at the side-stand micro switch, mounted on the frame, flush it out with WD40 or something similar ............ Let us know how you get on.

Does the bike have a sidestand switch that cuts the power if the stand is left down? If it does, disconnect it and temporarily join the ends together and try starting....

this may help,it doesnt sound like the clutch is out of adjustment,it sounds like the clutch plates have become stuck together,(this happens quite a bit if the bike has been parked for a while..ie over winter)..to fix it get the bike moving,down a drive way or something..then just bang it into gear,then shift into the highest gear you can by shifting without the clutch,once you have a bit of pace on simply hold the clutch lever in and work the throttle on and off all the while holding the clutch lever in,the clutch should free itself fairly quickly and should be back to normall,a lot of older bikes are good at doing this..hope this helps

Sounds like a fueling problem either water in the carbs or the fuel flow from the tap is insufficient. If there is a vacuum pipe it may have been dislodged or holed.
