Valve clearance problems, ZS169FMM, :(

[davidraaymakers]

Dear Forum Members,

First of all i'm new to this forum, and don't have much experience with chinese bikes...
I have bought an Xmotos 250cc bike with a Zongshen zs169fmm engine.
I teared the engine apart, inspected al the components and everything looks good.
But I can't get the valve clearance right.. So I'm searching for the right valve clearance for this particulair engine.
I hope someone here can help me, I'm running out of options.

Thanks in advance!

69 OHC http://www.zse.cc/Upload/motor/CB250-09474981799.jpg is some oddball. Why not ask importer/ bike maker / Zongshen...

Thanks for your quick reply, @humanbeing I have set my inlet and outlet valves to 0.25mm but it is backfiring and not running smoothly. I have set this clearances because I saw a youtube video with a Zongshen watercooled engine. And that guy set his valves, to 0.30mm but it did not rumble as nice when he let of gas, so he set them to 0.20mm and it ran perfectly. (this is the youtube video btw https://www.youtube.com/watch?v=MlGioj7SB48) But i'm contacting the dealers right now. I'll be back ;)
