What causes a Xingfu 250 motorcycle to stall when braking?

[DylanFitz]

Xingfu 250 motorcycle stalls when braking for the following reasons: Spark plug fouling: Stalling during braking while riding is caused by spark plug fouling, which requires drying before restarting. This may result from improper handling of oil burning issues. Although motorcycles are not highly precise machines, their disassembly and reassembly still demand considerable expertise. It's essential to seek repairs from reputable and professional service centers. Fuel atomization issues: While high idle speed during cold starts is normal, stalling is the main concern, likely caused by poor fuel atomization—indicating problems in the fuel supply or spray system. Replacing cylinder liners and piston rings typically addresses oil burning and power loss issues, but post-replacement break-in is necessary, and problems may still arise.
