Report Strange thing happening with my K750... in Dneprs, Urals, etc. - Pre 2001 Posted February 6, 2016 I should add that a bad ground for the system can trump all,,, check grounds thoroughly. Additionally a over or under charging system will most definitely affect a engine running. Over charging will burn out the condenser and points and coil if let go too long. Under will starve the coil the necessary base voltage for loading and the spark plugs will not have enough voltage to have a good spark to jump their gap,, resulting in a poor ignition burn.
