Hello,
I have a grubee skyhawk 66cc. I rode my bike in rain and went through some puddles. The bike would not run so I had to pedal home. I let the bike sit for a few days. When it got below freezing i took it out for a quick spin but it would not continuously run and would cut out. I removed the top-end and did some port cleanup then put it back with the piston arrow pointing to the exhaust. The bike now will not give a spark. I have run the tests below as @scubaru89 describes in his post:https://motoredbikes.com/threads/engine-stopped-running-think-its-cdi-need-advice.39203/
Magneto Check:
Combo______Target______Measured______Scale
Black/White----2 Ohms----------3.2 Ohms----------200
Blue/White-----300-400 ohms------302 ohms------ALL
CDI Check:
Combo______Target________Measured______Scale
+Blue/-Black---NULL---------------NULL---------------ALL
-Blue/+Black---130-150K ohms---40-180(flash)----200
+Plug/-Blue-----135-155K ohms---1500(flash)-------2000k
Plug/Black------2.5-2.7 K-----------7.0----------------20K
For the CDI values the readings just appear for a second then leave. Is that normal? Also, I'm not quite sure if the resistance values are in the right ranges.
From the Bikeberry youtube tutorial the magneto leads give the same 302 ohm BUT the CDI leads do not show ANY resistance. This makes me believe that I fried my CDI by running in the rain.
Any insight or suggestions are appreciated,
velzie.
