Pictorial how to mod 384 v force reeds to fit in to an rd motor w out adding a reed spacer or grinding intake.
these will go right in w no other mods to the motor . the upside is it has double the reeds, and they are 1 pc. Ideal for running stock up to 30mm carbs.

open up the left and right ID of the reed stuffer on the v force with a round file. they are a bit small on the sides, you need to remove about 1/2-1mm per side.

install like stock unit, but use gasket between reed and intake as well. will need ot trim ears off astock intake if you have one.
done. 4 petal c/f reeds.

Thanks Mark!
Should mention UPP manifolds are flat-backed without ears, and go straight on without trimming.
I had a tough time getting trimmed stock manifolds to seal.
true. I haven't had an issue personally, but i finish them off on a block w sandpaper. (if i use the stock ones). the upps are def better way to go though.
Would you recommend that tack life caliper? I love the big display, and I see they're inexpensive :clap:
the caliper has been pretty good overall
What noticeable change(s) in performance?
Or, do you need a certain modification to see a real benefit?
honestly, just better transitions and crisper response
