on my 70 rox its got everything done to it reeds pipe clutch carb rollers belt crank and doppler boost bottle. but its still got a standard filter box with a malossi filter if i bought a DOPPLER TUNING SPORTS FILTER would it make any difference to my bike.
Yeah it'd seize up after a mile or so.. need to upjet the carb. imo all they do is make your ped sound really well, although some would argue its just a useless fuel waster. been covered alot of times before, use the search man
just keep the stock airbox, no need for an open filter, they just make your bike too loud and use more fuel
if its the Doppler air system filter, i had one of them... they got 2 pretty small inlet holes in them (venturi's) designed to boost low/mid range torque, but a restriction all the same on top end, i ended up hacking the end out to make a traditional open type filter :tdwn: i dont really rate it to be honest, bit of a waste of money :tdwn:
