Recommended Posts

hey guys i have a gilera dna 50 gp experience and have just bought a new viper exhaust for it it was advertised as a sport exhaust and so everyone says it is aswell

i eventually put it on and now can only go about 30 maybe 40 kmh on a straight bearing in mind with stock 65 to 70 i have no idea what to do.

downhill is a diff story though itl go up to about 96kmh so i just dont know? same with just starting off for first 20 secs u get on it after leaving it parked for awhile it will shot like a fricken rocket but then u start to feel a drag and get brought back down to 30 or 40?

and as for up hill HA ur better of walking and in many cases i had to talk about embarrassment does anyone have any solutions??
