I have cleaned out the carbs as much as i can and everytime i try to get the 450 to run it dies after i turn the choke off and to keep it running it has to be at half throttle.

I have same problem with two 400's I have and just posted about it.

Check your valves lately or ever ?

no, cause the main prob was with the carbs cause it sits, but i looked at the needle placement and it may be getting to much air somehow so idk wat to do

When you cleaned the carb did you remove all the jets and fuel air screws? Check your air filter and the pit cock for any blockage.

Try Star Tron additive in your fuel, I just aquired some and did not ride machine enough to give a truthful opinion of it but from the reviews it sounds like it WORKS!

8OZ TREATS 48 GALLONS and u can't overdue it.
