Break in period - Page 7

Since I can't edit on my phone..

I can however see the forces acting for a longer duration on the piston at higher revs since the same amount of force is being applied over a longer distance/time.

Power produced would be the same I agree, but the G-forces are higher in 1st.... after all it is easier to loop a bike in 1st than 2nd or 3rd. So I would think it would put more load on the bearings. But I don't know shit about physics.

Damn this thread is long. I forgot I posted it on Thursday/Friday before going away.

That's not to say if I took it to the track right away I would have had problems.

You might be better off asking what tires are best for street riding.

I figured this would be a questionable subject but I thought I'd take my chances on the answers.

I know what you mean. I rode mine per break-in home from the dealer. Hubby asked why I was going so slow (not even the speed limit of 55mph). I told him I was following break-in... so after that he told me to at least go the speed limit.

That is kind of my thought, but at the same time I couldn't not do the speed limit for 1000 miles or whatever break-in suggested.

I meant at higher gears .

For a given amount of air & fuel introduced (throttle), a motor will produce the same output & the internals "see" the same thermal & mechanical stresses, regardless of which gear it's in - it's only the reaction (acceleration) which varies. (edit: assuming it's not 'free' revving)

So which oil should I use for break-in?....
