Just installed a tachomter on my Manco Thunderbird running a 79cc Predator engine. Just wondering if the default 1P1r ( 1 spark per revolution) is the correct setting?
After testing bike reached top speed of 31mph with 4040rpms...
Engine is stock besides NGK spark plug added and stock Torch...
The red one came from Indiana and the blue one came from Cleveland. Not sure what make either one is but red one has a predator 79cc engine and the other has predator 212cc engine. They are fun to ride and is a good way to get my 14 year old into engineering.
