grounding issue maybe??? 2001 FX650

We were having trouble starting our newest addition to the team - a mint 2001 FX650

We test for spark and it is strong and at proper timing, however you have to REALLY spin the motor quick to get it to spark!

With no spark plug in hole, lay plug on engine and crank by hand - consistant beautiful spark.

With compression tester in engine, kicking engine over you need to really spin that motor to make spark

The ODD thing about it is, if I remove compression tester, it takes 2-3 kicks by hand to get the first spark, then it fires every time?????

Wiring on this bike was a mess. we basically had to make our own wire harness.

From the engine stator, I have blue wire going to gound, 3 wires for the ignition pluged into CDI. then 2 yellow wires. I plugged them both into rectifyer although it seems that one should be left unplugged???

next, there is one wire from the rectifyer that goes to ground?

I have an orange wire going to the kill switch, and another from CDi going to ground.

Is it normal to have to spin engine so fast to get a spark? Is there a ground mising?
 
does your CDI have a grey and a white wire?

one of the yellow wires should go into a red wire so that the red in has a red and a yellow out. this is all from memory :?

Ah, OK. One of the yellow wires does not go to regulator, directly backfeeds into battery probably to get strong charging.

I do not have a high/low/start switch. do you have any sugestions where I could find one?

thanks
 
they come up regularly on ebay and also DCR has some spare usually

I guess I can't - I dont seem to have a proper rectifyer to convert it to DC. I have been using the wire diagram for the other model and there is a seperate regulator for the lights.
