Evening all. I have a very weak spark from my BGM full DC set-up ( BGM stator and flywheel). I have read of problems with the pick-up height not being aligned with the magnets on occasion, usually with non BGM flywheels. Anybody had it on a full BGM setup? Secondly...how do you actually check/ measure the alignment? Everything is new and all the bits and bobs cdi,plug lead blah blah have been swapped at least once during my testing.
Thanks, Sam

I think the pick up alignment will only affect the triggering of the spark (miss fire) rather than the strength of it. Check the resistance of the LT coil which for a BGM should be over 500 ohms. Also check that you have a good, solid earth from the engine to the frame. You could try another CDI (less than £10 from ebay) just to be certain
