The salesman at my LHS told me now that he has had no comebacks or problems with other 4 strokes he has sold. He is not saying it in so many words that I am at fault and this is the same guy that told me there is no need for extra castor added or after run oil unless the motor is stored for a long period, this I can understand but the longest this motor has not been used must be a month maximum. Now I have to fork out R200 for new bearings for something that is not my fault. The agent for saito told me that after run oil is necessary as nitro eats metal now what I cant understand that these two people are telling me two different things surely there is something wrong with this picture. The more I hear the more the motor gurus on this forum advising the use of a castor mix with synthetic oil in 10% Cool Power is the way to go and the use of after run oil a must after every run.
