Hi. I have a gilera dna 50 fitted with sports exhaust, new variator kit, rollers, tighter clutch springs and drive belt. It starts fine and runs for a few mins when going along the road it will just die (in hot and cold weather) Sad

Any ideas why? and how i can fix it? thanks in advance for any help Smile

sorry forgot to mention that after cutting out it will not start on electric or kick start for a godd 10mins!

Sounds like a fueling problem. Either Auto choke, jetting (for the sports exhaust) fuel blockage or if you're really lucky it could well be just a fuel tank breather blockage. I'd check that first myself.

sound like an outo choke to me

on top of the carb in a black box, how it works is as soon as the engine sarts running, power is applied to a heater that heats up a bit of wax which expands, pushing a plunger out and cutting off the choke.
just ake the 4 screws off the engine top cover, unscrew the choke, and apply 12volts to the two wires.

according to haynes, it sould me 11mm long at cold and after 5 mins, about 14 / 15mm

hope it helps Thumbs Up
