do the bike die like is run out of gas?
you down shift on a uphill with the throttle wide open when the bike is slowing down correct? thats when the bike die?

if yes, then you have little fuel going to the carb. may be a clogged tap, a bad fuel line, a dirty carb or a bad gas tank breather. on that bike the vent is located on the cap.

no it just dies out after a straight away every time, i bring it up to 4th and then as soon as i start to slow down at the corner after it, the bike slowly dies as if the bike has been turned off.

If the tank IS NOT venting properly it would create a vacuum in the tank and the fuel would not flow until the vacuum bleeds off. This us usually caused by a blocked breather hose or a stuck valve in the cap. Easy to figure out, try riding it with like 1/4 tank of fuel and either a loose or no cap. If it doesn't do the same thing there is your problem.
