Hello Gentlemen

Am looking for some 54mm Velocity Stacks for my ever growing mods list ...........If anyone has an ideas can you let me know ........

Thank god the snow has gone , all we need now is a good load of rain to wash the roads down and the Bike will be out to try out the new airbox mod / cans and chip ........Raised rear height as well by 12mm .... .....DRY ROADS NEEDED

Aprilia sell the plastic ones for something like £14, one of the early Milles uses them, can't remember which one though.

Was hoping to get the 54mm evo Velocity stacks billet aluminum ..........think A1 racing have them so maybe try there ........

Thanks for the reply though ........will keep people informed ..........

hi was just wondering are you putting 54mm velocity stacks on top of standard throttle bodies? only i was doing my own airbox mod last week and was wondering what difference modifying these would make? i have a similar mod list as yourself to try out, airbox, chip and rear shock. bring on the heat!

Had a set i fitted to an old RSVR i had as there was an improvement for sure but only a small one ..........just trying to get the best out of the baby .......Dry days miles away but fingers crossed not that far ...........Just been on A1 racing and found some on there for sale .......$65 .......on there way to me now !!!

i have the 54mm throttle bodies fitted to mine - and i do like what they give :)

with the 54 mm thottle bodies did you just get 51's bored out? what do you do with the butterfly flap at the top?

i bought/swapt/dealt with paddy for them - so no idea

from the velocity stacks that came with them, I have a suspicion that they may well be evo in origin - certainly feel quality

they just replace what's there ........fit straight on ...................from what i remember

Just ordered mine delivered from A1 for $119 so trying my hardest not to work that out in Sterling ...........and for gods sake don't tell the misses !!!

I don't wish to rain on your parade but I can not see how enlarging the velocity stack without a corresponding change in the throttle bodies, is going to improve things. Surely there will be a step change between the 54mm velocity stack and the 51mm throttle body? If there is then I expect it will have a detrimental effect rather than a positive one.

Will have to let you know when they get here and are fitted .............they did make a bit of difference on Throttle response last time ( that was on an rsvr though ) so will give them a go .....and if not they will be for sale on Ebay in about two weeks !!! .........and yes they do make them for the Falco .....

Anything to try and get a little bit more out of the Falco without going mental and getting the engine out !!!!! ....Winters getting boring now so something else to do while waiting for the salt to be washed away on the roads ........
