Ok so I will preface this with, I am no wizard with a multimeter but I do somewhat understand what I should be looking for. And I have search this forums and many others with no luck.
So I got this 74 cb125 for free and it was sitting for 30 years. I have cleaned the gas tank and carb about 10 times. Gapped the points and done static timing. The battery is fairly new. I have spark and I'm getting fuel.
It will start when the battery is full charge (seeing 6.3v w key off) and when it is running I can see 7.03v so I know its charging. It will idle and run perfectly (idled for about 20 mins with no voltage drop across the terminals)
But here is the issue. It WILL NOT go above 7k rpm and when you hit the brake, turn on headlight or blinkers (which dont flash, they stay solid) it wont go above 4k rpm.
And I checked the battery was 6.3v when I turned it off, 4 hrs later with the key off the whole time it tested 3.03v
So i guess my question is, what is my next test? I've been beating my head off the wall.
