Hi All,
Finally got a bit of time to look at a unitrac motor I bought in the summer, It has solid front engine mounts so I suspected it may have come out of a special or racer. Lifted the cam cover and all is well, but the non-original cams may confirm my initial thoughts. Does any one recognise these cams? They are fitted on slotted cam sprockets and have made in USA on one side and the markings shown in the pics on the other. When I pop them out to check the rest of the motor, bar marking them so they go back in the same position how do I know the optimum position to refit them in as there are no marks on the slotted cam wheels?
Thanks in advance
Dave

Dave, they look like APE adjustable sprockets. If you look carefully there should be some dots that mark positioning. Failing that do as man says and mark everything up carefully before you remove!
Also if you are returning to rubber mounts can we do a deal on the solid engine mounts? I need to get solid mounts sorted for my Moto Martin. Can swap for rubbers assuming I can get them out!

Looks like CWC is the company who casts the blanks. EP14 is part number for the blank (one of many different types of blank)
Is there any marking or stamped numbers on the ends where the 'D' rubbers sit.
If you cant identify them specifically go for around 108 to 110 using the lobe centre method if they prove to be around .410" lift or thereabouts.
As was suggested above; mark them accurately and measure the existing LC.
They may be out or jumped a tooth but it will give you a number to think about.

Hi and thanks for the responses, went back to the garage and had another look, found these numbers on the bit that the sprockets bolt to. The sprockets did have marks which lined up at tdc and were the required number of rivets apart. What do the numbers mean and are they suitable for a road / track day bike?
Thanks again,
Dave
