Right. Cured i hope! Spayed electrical contact cleaner spray into ignition block. Now starts each time and no stalls yet!

New coil, stripped and cleaned carb, new plug. So clean fuel line clean electrics except for ECU. Cant test that!

Brand new coil and lead fitted. plug cap in tolerance. Stripped and cleaned carb cehcked float and main jet set correct. no. Fuel straight out of tank, through filter (checked) into carb.

Well that made no difference! Fault same as before. Batt voltage ok, when it starts it runs ok for 2 minutes riding then cuts out. Reatarts and runs sweet! Then wont restart after turning off. Battery?

Rekon i have found fault, in the ignition coil. Intermittent so only option to change it!!

Changed plug made no difference

Stripped and cleaned carb. Started first click but failed on restart!

Cleaned tank cap and filter, plus drained float valve but fuel kept coming through! Possible cause?

My yamaha ybr 125 has developed a fault, as described posted in newbie section! Started to cut out while riding after a short stop, restarted while still moving. Now has begun to be hard to start. When starts runs sweet. 2006 standard carb version.

My apologies. Hi returning to bikes after long gap. Aiming to get full licence sooner rather than later.

Have seen other posts about similar problems. My problem starts sometimes after short stops and at speed. It cuts out similar to running out of fuel. I can restart engine once its dead and ride on fine for a while but it has begun to become more regular. Plenty of fuel and plug looks fine and set correctly.
