I just finshed a semi-rebuild on my '88 Suzuki DT115 and would like to disable the oil injection system so I'll have to mix my oil and gas. What is the recommended procedure?<br /><br />I also am trying to install an aftermarket Tachometer, but am not getting any signal from the Tachometer Control Unit (which per the Suzuki manual only appears on the Canadan models). The Suzuki model does not provide any trouble shooting info, and hardley acknowledges it exists. Any trouble shooting suggestions?
