Title: reed valve inlet tract?
Post by: Gil Gallad on November 28, 2019, 08:43:06 AM
ok, i'm converting a ramair gt250 to reed valve. after measuring the set-up on an rd250, the way i've made my set-up makes it about 25mm longer than the rd. is this unacceptable? will it sort of work? don't want to go ahead with the welding of the reed cage til i get an idea if it will work or not. any ideas, please reply  ;D
cheers, gil.

Your on the right track. Leave room for reed tips to move and breathe.
Waiting for a cheap GT250 to cross my path. We didn't get X7's here

i never liked the x7 anyway. at the side of a proper ramair gt250 it looked like a girl's bike  ;D
cheers, gil.
p.s. apologies to any x7 owners out there, just my personal opinion.
