2 stroke timing “stator”

[declan]

Hi I’m looking into a ktm sx 250 the guy says it’s got a new cdi and stator but it don’t run because he don’t know how to time it but shouldn’t it run but run like shit but still run?

[Calum]

It's two stroke? Therefore the timing is set by the static angle and programmed into the cdi

@calum soooo? I know nothing about timing I’ve gave up on the bike anyway since the guy wanted 1,500 for a none working bike but can you tell me more? I personally get the feeling something else is wrong with it I couldn’t really find anything on the internet I know about (4t timing)

@declan Work it out, what are you timing on a four stroke. What are you timing on a two stroke.If you already know about timing thrn this should be obvious.

What Calum is saying is the timing is fixed, if the stator and cdi is new then spark should be being produced, easy to check by removing plug and looking (assuming all wiring etc is ok) if it's not starting something else is wrong. I always think if you can't see a bike running walk away unless the price is reflective of that condition, who knows what could be wrong? If it was that easy vendor would have fixed it

@oldman Well I was trying to let him figure it out.

If on a four stroke you need to keep the cranked timed up with the cam shafts, the timing is not only the ignition, but the inlet exhaust duration overlap timings. But since there are no valves on a two stroke, you're purely looking at ignition timing. Done discredit the fact he may have bought a aftermarket reprogrammable ignition, but if it was just a stock CDI, then there is no ignition curve to map. So it would probably have been something else. Sounds suspect to me.

[oldman]

Doesn't sound right to me either, especially for that money for a non runner. Would walk away personally. My mate has just sold his ktm for not much more, full working order and serviced. Used to do enduros but making room for a white dt

@oldman yeah I walked away seller was a prick anyway lol
