UPDATED gilera runner 172cc water cooled barrel and piston has some marks on the piston, but runs fine as it came off a running bike which was dynoed at 23bhp might of had some port work done to it not sure, the dyno sheet comes with it aswell, looking for 100 delivered ono gilera runner/dragster Malossi cdi £60 Malossi delta will fit runners, dragsters , typhoons lightly used £45 brand new malossi old shape typhoon engine gears (may also fit old shape runners) £35 malossi new shape gilera runner/dragster gears these have aready been pressed and come complete all the gear box all the gears u need so its bolt on, no need to pay a garage to press the gears in £45 gilera runner new shape casing which have been ported and polished chrome , it needs a clean £50
it will add arounf 5mph as it has been polished it is more aerodynamic thus givng the air a smooth surface to glide across, a non polished one is not as smooth and normally quite grainy this causes the air to ripple and forces it into each other causing the bike to be slowed down by the destructive waves
hes right abz i think you should thank him for promoting your side casing lol p.s.the only thing the holes on the casing will do is cool down the clutch quicker
