I have an 1100 v star silverado. Took the course but they never advised me on these two things. Can anyone shed some light on them? When driving a twisting and turning up hill and down hill back road speed limit 45-50 would you just stay in 3rd gear?
Also when downshifting to 2nd gear to slow down, hand off the throttle, clutch fully engaged bike slows and then stalls, is this because I dont give it any gas?  

It'd have to be a really steep hill before I'd stay in 3rd gear going up it at 45mph. My Honda 1100 pulls just fine in 5th gear, with just a tiny bit more throttle. If you're slowing down for the turns, that'd be a completely different situation.

Did you have the bike re-jetted? New pipes perhaps? New intake?

At any speed, the engine should just sit there and idle when there's no throttle. Coasting speed of the bike shouldn't matter.
My 1st guess is you had intake/exhaust work, and they never adjusted the pilot circuit etc. So, you don't get enough gas, and it just shuts down.

As to the gear, when on twisties, I tend to leave it in 1 gear. Pick the highest gear that gives you strong pickup when you crank it at the speed you want to be going. Yes, your mileage is going to suffer while you're doing it, but, think of it as playtime, and, you're not doing it all the time.  

Not sure I made it clear enough on the down shifting. I am going about 40 downshift to 2nd let the clutch out no throttle at all, the bike slows down as it should then stalls. Should I be giving it some gas to eliminate that? Is that normal?  

The bike is stock and only has 240 miles on it  

Disengage the clutch as it approaches idling rpm, when slowing down. It's already long past time to downshift to 1st anyways. If idling has too little power to keep the bike running in first, you probably have the idle set too slow.

OK Thank you I will try increasing the idle
