:( i had my quad running great with the 11.5:1 440 piston 450r carb, 50 pilot, 192 main, stock headers and a slip-on exhaust with lid off and K&N with lid off and wb cdi ignition.
i lost the head gasket from weak studs
replaced them with heavy duty studs
put 12.5:1 piston and put on full wb R4 exhaust with valve job done
it is now running too lean and i seem to have little or nothing at high rpms
my guess is to adust air fuel mixture for new changes
any one else run a similar setup and can coment?
