    wisco piston arrow question

    I have the welded up lower end of my TRX250 back together finally. Now I am waiting on the rings. The question that I have is:
    What way does the arrow face. Stock is to the intake side, but if memory serves me correctly, wiseco points to the exhaust.

    Just want to get it right.

    Thanks,
    Dave

    Arrow is airflow direction, and should always point to the exhaust whether it be Wiseco OR OEM piston.

    I asked because the manual I thought said to point the arrow at the intake! It did not make sense to me.
