I can not believe I'm saying this, but for the first time I must disagree with you ... I have been told by a few different guys ( one machinist that works on recreational vehicles, and a guy that works at a atv/mc parts and service shop ) that riding at wot for more than 6 - 10 seconds in top gear without letting off the throttle can starve the upper part of the crank case of oil, thus preventing adequate lubrication. I forget exactly how they explained it but it made perfect sense and I very much trust their knowledge and judgement. Whatever the case may be I do not like taking risks when it comes to wasting money unnecessarily ! I'm not trying to shoot you down as we all now you have vast
knowledge and experience and I have never disagreed with you before, but that is what I was taught and believe so I had to share my 2 cents.
