If you have enough battery charge to crank the engine, that's more than enough to power the CDI. A voltage drop to 10.5V during cranking is normal. The battery ain't your problem.

However, if you connect another battery in parallel, like when you jump start a car, and it still doesn't fire, then you can be certain the battery is not the problem.
