I drgged out my yellow CT90K2 and checked the battery voltage after it sat for a week or two , it had 6.7 VDC , I started it up and it ran fine but still hiccuped when I turned on the headlight and stalled when I turned on the high beam .

I re started it and tried again , @ cold idle it stalls as soon as I turn on the high beam , this needs looking at as it charges terrific above idle , not so much at idle speed .

Then I adjusted the clutch about 1/16th a turn .

I also made a little modification you'll have to join us Sunday next for the Sta. Barbera Ride to see.......
