best expansion pipe fot GT240 engine

[martyn dwane]

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.

Jl or franspeed race is the recommended pipe of Eden I ran one on mine was spot on

[martyn dwane]

I have a TSR evo he can try but i will let him know about the JL/Fran race.

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

Opting for a Chiselspeed CST7.

He certainly has !

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.
