HI,
I have just put my head back on after installing two new exhaust studs. The bike has been running perfectly before i removed the head.
Now when I fire her up she only runs on cyl 1 and 4.?? Hand test on the exhaust shows its 2 and 3 not firing.
Go figure? Plugs are ok, spark on each when held on the head. Coils ok, as I swapped them over to test and they ran on 1 and 4 again. Plugs are labelled 1 -4, easy.
I cant see it being the cams, you can only put them in one way......T timing mark on mag lined up ok, and both punch marks line upwards (cams are labeled I and E so you can get it wrong)I only undid the sprocket on the exhaust to get the chain off, as its at the front and easier to get at.
So im now wondering if a bit of crud got dislodged in the carbs when i removed them. Any thoughts peeps?
