i built a GT240 a couple of years back for a friend,he now wants me to give a full service, new rings,petals etc,etc.
he`s been using a AF road Rally that's seen better days and asked what pipe to replace it with . Being a clubman user i thought i would ask my fellow LCGB members advice. Over to you .TIA

ive got a TSR EVO on mine - i shortend the stub and first part of the pipe by 2 cm ( 1 cm of each part) to give me more ground clearance. It works very well with my GT240 ( standard - no tune) and 30mm Dellorto. Plenty of power, nice smooth curve and lots of torque.

Fran race on mine, runs a treat. Makes for a nice rideable scooter with the 30mm PHBH.

CST7 is currently the best expansion for the GT240.
They also run great on Ron's ST too, no powerband but with the ST obviously but they work very well.
