    Hi All.

    Hope your out enjoying the weather. Does anybody run Fully synthetic in their Bird Please?
    Bit concerned with the Torque that I may get clutch slip.No worried about the cost, just want the best really.

    Any advise is greatly appreciated.

    Regards Paul.

    A proper dedicated motorcycle oil - synthetic, semi synth or mineral - is designed to work with a wet clutch. Do not be tempted to use ordinary motor (car) oil as it will cause clutch slip because it is not designed to work with a wet clutch.

    If you look for an oil of the correct viscosity for your Tbird that's to the JASA MA2 spec that's specifically for motorcycles with a wet clutch

    I have a T-Bird Commander (1700 cc) and I only use Castrol Power 1 Racing 4T full synthetic oil. The price is ridiculous (~$11.00 per quart in the US) because it has a picture of a motorcycle on the bottle, but it meets the specifications outlined by Triumph. This is what my owner manual calls for:

    "Semi or fully synthetic 10W/40 or 10W/50 motorcycle engine oil which meets specification API SH (or higher) and JASO MA, such as Castrol Power 1 Racing 4T 10W-40 (fully synthetic) engine oil, sold as Castrol Power RS Racing 4T 10W-40 (fully synthetic) in some countries"

    I am using Castrol 10/40 4T synthetic only because that is what the owners manual calls for (even has Castrol sticker on engine from Factory)
