Hi, if u just wack reeds on without porting the piston etc, u may or may not notice a small torque increase. U'll probly have 2 downjet a tad as it'll stop reversion blowback. If u do the piston port & boost port mods etc, u'll notice a substantial torque increase, tho u'll also need 2 do a sizeable upjet due 2 the much lower intake velocity that results from 180 degree intake. It is worth doing, IMO, so long as ur motor's up 2 it, especially the small end bearing. Cheers
