Yamaha blaster sputters

[Sunburnt Silv]

Blaster sputters won’t hit power band has brand new top end reeds has wiseco rings stock size an bearing carburetor was fully cleaned nothing with the carb fixes this issue I have ngk spark plug it’s a br8es or whatever the stock plug numbers are can’t remember but when I go to ride the quad it will sputter trying to hit power band but won’t get there I used Yamaha bond 4 on the sealing surface I used YB4 on the crank collar an key to make sure it don’t leak nothin had changed the way it runs idle hangs a little when you rev it it takes a second for the idle to come down

Do a leakdown test. Never trust what “should” with lean symptoms..

Did it run this way before you tore it down? Did you do heat cycles and retorque head and base nuts?
