Vee Two recommends that piston to valve clearance is checked.
Please check rotation of camshaft in cylinder head before assembly. Some early single heads may require the removal of a small amount of the head material from the inside of the rocker box to allow clearance for the extra lift from this camshaft. This work can be performed by any competent motorcycle mechanic.
