Valve Train

When installing Velva Touch™ Lifters...

• Check to make sure the screw that holds the lifters in the block are tight. Do not over tighten; you could distort the lifter bores.
   
• Trial fit the lifters in the engine; make sure the lifters are free in the bores after you tighten them down.
   
• If any of the lifters tighten up in the bores after you tighten them down, remove the nose cone and check to see if the blocks are touching inside the engine. If they are, remove them and clearance the blocks with a die grinder.
   
• For street bikes adjust the pushrod out 1 1/2 turns from zero lash. If you have a race bike adjust the front pushrods 7 wrench flats and the rear 4 wrench flats.

NOTE: When installing any hydraulic lifter, always clean the tappet screen, which filters the oil to the lifters.

NOTE: Always let the front lifters bleed down before rotating the engine to install the rear lifter blocks.
