Install crank and cam gears with the chain. Align the dots here also. Install the crank & Cam bolts using RED Loctite. 35 Ft. lbs cam 25 Ft. lbs crank. Hold the foot brake with the bike in gear so the engine doesn’t move while torqueing.

Remember how we cut the old push rods out with bolt cutters? We are installing an adjustable push rod kit.

With the dots still aligned on the crank and cam gear you can now install the rear cylinder push rods. The longest push rods are for the exhaust and the shorter ones are the intake. On the rear

30 mins for the lifters to bleed down, before you go any further. When the lifters have bled down you will be able to turn them with your fingers. Now to install the front push rods rotate the engine till dots on the crank and cam gear are 180°from there alignment point (lifter will be on base circle of the cam) Now you can install the front push rods, tubes and adjust them same as the rear.

Now you can install the cam cover with a new gasket and reassemble the rest of the bike. If you have any questions for Jayme at Dead End Cycles feel free to email him or call the shop. deadendcycles@artelco.net www.deadendcycles.com 419-393-2574
