I am used to riding Pulsar 150, when I press full clutch in that, the engine is still alive without the need of throttle/acceleration/raise to keep the minimum rpm. But I was riding a TVS Apache RTR 200 recently and when I wanted to stop the bike, I pressed full clutch to stop but the engine died after around a second. Is it required by design to give throttle/acceleration/raise to maintain minimum rpm or does the bike have problems.
If your engine requires throttle to keep it from stalling in neutral or with the clutch disengaged then there's a problem. There's nothing cool or desirable about having to keep throttle on to prevent your engine from quitting on you, it could leave you without power when you really need it, so you should get it resolved. There are many things it could be, but one easy thing you could look at is the idle adjustment. There's a screw at the end of the throttle cable, you screw it in to increase the idle speed, and out to reduce it. I'd try screwing it in to see if that helps.
