derbi gpr125

hi i know this is a scooter forum, but its a 125 two stroke anyway

as i am turning 17 next month i am looking to purchase a derbi gpr125 or a senda (same engine)


now standard these engines are 17bhp but i have heard after a simple derestriction that this can be boosted to around 33 bhp

does anybody know of the method to do this derestriction and what parts are needed


many thanks in advanced

Restricions are founded mostly in:

Exhaust ( at the begining near the exhaust port or at the (dutch: *demper* ) end
Airbox
Carburator

Good luck!

i heard that there also was a electric limiter....under the seat...(gpr125)
take out the fuse thats hidden there and give it another go...

ps.
i think you know that you owe us some pics now....

hahah
i will when i get the bike

hopefully i will go down the local aprillia today and try an rs125 out for size, seen as thehy are basically the same bike

i am rather a large lad
bout 6ft5 and weighing around 20 stone
