V force reeds are just another way of saying carbon reeds.
Possibly a bigger inlet but without a bigger carb it's wasted money. Either get youself some boysen or like me hytech reeds. Same job but cost you £25.
If you really want to go down te tuning route. Grab yourself a 4DL vhsa dellorto carb. 32mm. And the 4dl inlet manifold and cage. Install carbon reeds to that and enjoy the benefits.
But be prepared to fook about with jets and air intake.
I'd say unless your machine is tuned there isn't a lot you can pick up in terms of horse power.
