P11A,back on the road

They were printed , but not easy to find in the UK ,  You may be able to get a re-print. One of the leading experts resides in the UK. So ask away . You may be lucky.

Giovanni; Congratulation on acquiring your P11. Norton Atlas manuals will cover the motor and gearbox (although the gearbox shell is Matchless. Different Mounting lug location). A large issue with the P11 is keeping all the fame pacers in there correct locations when you take it apart. If it were my bike I would do a complete maintenance check for the peace of mind that everything is as it should be. Are you familiar with the Atlas Hybrids 2 tab under the History tab of the homepage? Anthony Curzon: hybrids@nortonownersclub.org, is our expert in residence.

There were two handbooks printed for the P11 series of bikes. The P11, G80CS, G85CS, with the red cover was published in March 1967. The P11A, G80CS, G85CS with the blue cover was published in January 1968. There were two parts books, for the P11A one was A4, and one A5 size for the P11A  series of bikes. The other parts book is for the high pipe single seat P11 only. The main points to check would be if the bike has been used for any sort of off road competition racing, as the lower frame tubes, and the front frame tubes can fracture. There were five types of oil tank used on the P11 series of bikes. Three alloy and two steel, so check that there is not any cracks in the seams of the oil tank.  As your is a P11A  if it is a later one it would have the steel oil tank or the forth one in the oil tank series of designs.The prop stand can be a problem if it is not fitted correctly. ANIL has a large stock of parts as well as selling the handbooks. I have seen the early P11 handbook that they sell, the one with the high pipes, but they may by now be selling the P11A blue cover one. The handbooks do not have a huge amount of info, but they do have enough for you to do the maintenance that you require. There was a company that i saw at the Stafford show many years ago, selling the P11A handbook. The front forks on the P11A are of the AMC Teledraulic type, and they have standard internals, and not the earlier P11 G80CS competition internals. One thing to be very careful of is that there is a mistake in both the P11 series of handbooks. This mistake in all the AMC parts books diagrams, goes from about 1956 up until 1968.This is for the rear wheel diagram of the rear wheels bearings and spacer arrangement.The rear wheel can suddenly lock up and the speedo cable wraps around the rear wheel spindle, and only releases when the speedo cable breaks. This is a very well know fault in AMC circles, and ownership. The oil seal on the speedo drive side should not go inside the cup but on the out side to the left. It is more of a spacer than an oil seal. Get this wrong, and it is only a matter of time before the inevitable will happens. 

Is it like the G25 CS where (according to the F Neil book) the pushrod must be pulled up out of the head before the head can be taken off?  That requires exhaust rocker spindles to be extracted.
