[rbgaz]

on a gp theres a few diffrent ones in stickys book just like to no which is meant to be best
one without a air scoop/one with airscoop/one with just a air divider no scoop /one with airscoop and diveder/ one with no air scoop or divder ?

[paulmgreen]

divider helps force air towards exhaust port apparently

[rbgaz]

cheers paul, so what about the air scoop what benfits y did they remove them from later ones ?

[Ian Hepworth]

Air scoop was to blow warm air onto carb/manifold to prevent carb icing up.

[rbgaz]

thats intresting learn somthing new every day
p.s your new remade racetour carb rubbers are shorter than the old ones !! cant get my 35tm on it

indian ones as advised by taffspeed with the correct flywheel ,the head cowl has a larger cut out on them so lets air escape quicker
