yep Farmall nailed the solution
Same deal with me, took the MSF course on the same Honda, very wide friction zone
then got my 650 about a week later.
Its not that the clutch on your bike is bad or the engine is stalling out. You got use to the honda wide zone riding the bike for as long as you owned it, and now your 650 is ... well its just different.
Its the same deal if you have two very different cars with manual transmissions, it takes a while to switch from one to the other so you can engage the clutch without thinking about it.
One thing to keep in mind, motorcycle clutch plates are in the motor oil bath, so you would have to try really hard to burn one out from slipping it too long, they are oil cooled. In a car 3 or 4 seconds slipping the clutch is too long. On a motorcycle you should intentionally be slipping the clutch to control the speed of the bike when going slow, like doing the 8's and U turns during the class.
Go back and do the class practice on your Vstar. Keep the bike stopped, find the friction zone and feel the bike pull forward, holding it back with your feet... Let the bike inch forward about a foot, then push it back, slip the clutch letting the bike creep forward, then push it back
do this several times till you feel the zone. Do it when you are stopped at a light if you want, let the lever out till the bike is pulling.. then if you need to crack the throttle a bit thats ok too.
If you do this then the bike is cold and it keeps stalling you pushed the choke back in too soon. When my 650 is dead cold I pull the choke all the way out to start it, and burp the throttle just a bit when it fires, then immediately push it in one click.... check the lights and brakes and push it in another click and take off.
Dont push it in the last bit all the way till you ride a 1/4 mile or so. When the bike is cold it will stall on you, which sucks if you are going around a corner (because the bike will then spiral into the turn harder).
On level ground you should be able to slip the clutch all the way engaged with a warm engine without giving it any gas and without stalling the bike. If you try several times and it wont do this, your idle screw might be set too slow. Its right on the side of the carb, you can turn it with your fingers to adjust the idle.
If you have the idle speed too high the bike will feel like its coasting when you let off the gas, instead of slowing the bike down from the engine back-compression.
Dont be afraid to tinker with it till it feels right for you.
And if you cant get use to the narrow friction zone, that modified lever is the way to go.
