Intake leak? bad crank seals? dirty carb?
sounds like a pretty racey motor... what kind of idle speed are you expecting from a performance built motor?
tee hee... boost bottle ! chuck that thang!

sounds souped up! i agree check intake and make new gaskets they can get finicky w/ time. Those walbros are cool but require a lot of adjustment - i'd mess with it. I have also had a high compression head blow out crank seals but (i think) thats super uncommon and if it was a production head that should not have happened. Check those as a last resort. -MOTO
so i got rid of boost bottle . and checked for air leaks found none should get rid of the walbron carb and go to a simpler nt carb with smaller jets. how do you tell if crank seals are blown out or bad. here is what it does it starts great and runs fine as long as your working the throttle. when you let off the throttle it falls on its face simply dies. any advice will help and appereciated

One way you can tell if you have a bad crank seal is by finding oil inside the magneto compartment, or in the primary leaking from around the pinion gear.
It's probably your carb then. It you have to buy a new one I recommend a Speed carb. They give my bikes a great all day idle. An NT has good idle too, but tend to load up a little. In comparison my bikes with a Speed carb sit there and idle like a clock all day.
