Slipnot, sorry for the confusion over the two books, (I'm getting rather old)

These old motors and the materials they are made of were constructed to work best at a given temprature in conjunction with the oils that were available at the time.
Not warming a motor before putting it under load will just lead to premature wear even with modern oils in it and running a bike under load with the choke on is even a bigger no no.
On a side note, did you know that you can actualy seize a cold motor?
Sam.
