Ossa Info Request

Recommended Posts

Hello, Can anyone help me out with some settings detail needed to finish my restoration of an OSSA TR 350 1977.

What is the Top Dead Center setting required for the Spark,

What are the Jet settings for a Bing carb,

Has anyone got a drawing of the Ignition wiring including a Kill Switch,

If you can help I will be very grateful,

Cheers,

Vaughan,

P.S. you can check progress of the restoration on our web site,

Ignition timing can be anywhere between 2mm BTDC and 3.5mm BTDC depending on what kind of response you want from the motor. Personal preference really - although on my MAR I could never tell any difference whhichever it was set at - just felt the same at 2 as it did at 3.5.

Can't help with the wiring as I've never owned one with the points ignition so not familiar with it. Can't you download a diagram from Mats Nyberg site?

Ditto the carb, never had one with a Bing but it may give the settings in the Clymer Ossa/Montesa/Bultaco combined manual (the thick one with the brown cover) as I think it has a supplement for the later bikes in the Ossa section.
