THROTTLE BODY

The TPI engine is fitted with a redesigned 39mm throttle body made by Dell`Orto. The airflow is regulated by a butterfly connected with a twin-cable throttle cam, which is operated by the handlebar throttle assembly. A throttle position sensor provides airflow data to the control unit. For MY20 the idle system was reworked allowing the idle speed to be set more precisely via the bypass screw. Also, the cold start system is improved for a better supply of extra air when opening a bypass. Oil supplied by the electronically controlled oil pump via an oil intake tube is mixed with the incoming air to lubricate the moving engine parts.
