Motoplat don't fit

[Paul Danik]

Gary,

   The Sachs engine number from Penton V-015 is 5389021, and the Sachs engine number from the original sales receipt from Penton Brothers Motorcycle Agency for Penton V-002 is 5389013. Both of these Pentons were built very early in 1968.  The number from your engine, 5499134, would indicate that it was built after the 1968 Pentons that I supplied the numbers from.  How long afterward, your guess is as good as mine.

   Thanks for presenting such an interesting topic.

Good luck.
Paul

Dan,

  On page 2 of Penton parts book 001, check out items 26 and 27, they are the  plug and washer for the oil injection hole in the early cast iron Sachs cylinder.  I have used the plugged oil injection hole for years as one of the clues as to if an early 68 Penton has the original engine in it.

Per Pauls discussion on the plug (and washer) on the early Sachs engines for the Pentons  is way I use to identify the early engines (too).  The engine that was in V001 when it was found was 5389598 which was a replacement engine to keep John's bike fresh for all the races he would enter.  It has the same bolt on the intake as Paul has described.

After reading this I went out to take a look at my 68ST. V-0144 has the oil injection plug on the intake and engine # 5499736.

Gary,

   It is a pleasure to have you be a part of the Penton Owners Group message board family.  

   Is the exhaust port on your cylinder oval or rectangular?  

   The fact that you have a top end bushing leads me to believe that you have an aluminum connecting rod and most likely a cast iron cylinder with a rectangular exhaust port.

   Is your bike a Wassell Trials bike like the one in this picture?

Take care,

Gary,
If you have the flywheel that will fit to the Sachs engine, then you can use the stator and coil. But the flywheel (9600162) will not fit to the Sachs engines.

Gary,
  No stir...we just enjoy seeing and hearing of things we don't see everyday.

Seeing is beleiving. Must definately be a rare unit. How long did they build these motors with pumps?? and what brands most likely used this set-up?? anyone know?? Was it short lived because of failure issues or was pre-mix just the easier way to go??

[Paul Danik]

Gary,

   Great pictures, thank you.

   I am curious as to what the serial numbers on your Wassells are?  Most all the ones in the states pretty much fall between 200 and 750, would you be kind enough to post yours?  They are on the steering head.

Also, have you ever seen a BSA Bantam powered Wassell?  From what I have read, the BSA engine was the original power source for the Wassells but the engine supply dried up. I know of several in the states, but they mostly have Sachs power.

Dan,

   Sachs was an engine supplier to many brands of motorcycles, both for street use and off road.  My guess is that the oil injected engines were used primarily for street use. Over the years I have seen both in print and in person a lot of Sachs powered off road machines and I don't recall any being oil injected, but quite possibly someone somewhere did use it for off road. As far as reliability of the oil pump system, just going on my own experience with Sachs engines I would bet a steak dinner that they were superb.....

That is neat!  I've never seen a side cover or oil injection before.  Now I wonder about the tank and does the oil injection cable hook up to the magura dual pull twist grip?
