RUNNING-IN
The chief point in running-in an engine is to allow it always to turn over lightly and smoothly; both high revs, and hard pulling or collar work should be avoided on account of the high bearing pressures endured. Whether yon drive at 25 or 35 miles it does not matter so long as the engine is neither "worked" nor revved . It is advisable to over-lubri-cate and -at the end1 of three or four hundred miles, a good plan is to drain, the sump and crank case (with the engine hot) and refill with fresh oil. Some riders adopt a similar practice in the case of the gear-box. During the first few hundred miles every part of the machine beds down and it is as well to check over all adjustments and the tight ness of the nuts.
