Cut-Out Problem
Hello everyone. I have had this problem for a while but never sought to resolve it as It does not happen that often. My bike is Derbi 125cc, with an air cooled four-stroke Yamaha engine. The petrol tank holds 8 Litres with a reserve of 1.5 Litres. Now when the bike uses about 3.5 litres something strange begins to happen:
1) I twist the throttle and have a delayed response.
2) The bike jerks so I knock down the gears.
3) The bike continues to jerk and loose power until it cuts out.
4) It takes a while to start it again.
Sometimes I choke the bike and it recovers. I have wondered about this, is it the petrol? Battery? It seems to happen after its been raining, when its cold or really warm but this is not exclusive. Spark plug is OK, air filter is OK, engine oil is OK, chain is OK, throttle cable is OK.
As I said not really a massive issue for me, as 3.5 litres can take me 80 miles. Any help/advice ot there?
P.s. hope you all had a good weekend in Dent, I froze my a**e off on top of holme moss.
