Questionhi there i have a honda vt250f and it starts alright when its cold but when it reaches working tempreture it statr to splater and then dies on its ass what can the problem be thanks
AnswerDimitrios, Check http://www.cmsnl.com/honda-vtr250-interceptor-vtr-1988-us_model1135/partslist/ for the parts involved.
Could be a lot of things.... water in the fuel system, weak pulser coils in the stator, bad coils, bad coil wires or spark plug caps, fouled spark plugs, loose/corroded wiring connections, failing charging system and more....
I would start by checking the condition of the fuel shut-off valve on the petcock. There is a diaphragm that can fail, which creates an air leak to the intake sytem and shuts down the fuel supply all at the same time.
Fuel system has a screen up inside the fuel tank, attached to the petcock, so you might want to drain the fuel tank and clean/replace the screen, while you are doing maintenance.
You have two carbs, two pulser coils to trigger the two ignition coils and all the wiring and hoses that connect everything together. So, if it isn't obvious whether the problem is affecting both cylinders, you will have to isolate which cylinder is losing power and then look at what effects that one cylinder... fuel, spark, compression or air flow.
When the bike starts to fail, try adding some choke to see if it improves the running. If so, then the engine is starving for fuel due to petcock diaphragm, most likely.
