Question about 2002 Yamaha TT-R 250
Well thats the thing, it doesn't really idle at 300, i will be out on a trail and it runs decent while im on it, but anytime im on a trail and need to decelerate to brake or just get off the throttle completey(even just to turn), it will die, by 300 rpm idle i just meant when im completely off the throttle for about a second itll stay runnin at extremely low idle fora second, if that, and then it dies, and sometimes it will idle at like 4000 rpm. it just woint stay at a constant 600 rpm.

Assuming you haven't done anything to the carb or cable, the revving up would indicate an air leak somewhere around the carb manifold, either at the head or at the carb/manifold couple.
300rpm is very low for a single to idle at, it should be around 600rpm for reliable idling.
To check for air leaks, spray CRC or WD-40 around the manifold while the bike is idling - you will hear a change in speed.
