Mine did 79.1HR 3001KM it did the portside main bearing back in Jan 2011 I took it to Orange berg the man who knows best about the problems with mains and just the trick to make them last and she is still going at around 200HR 8000KM now, and I never have had to adjust the rockers much at all.
I have always dropped the oil at around 200 to 300KM and always had lots of metal on the magnet, but now it's real good for the last 1000KM or so and always used DELO400 oil.

I have only had to adjust the rocker gap 2 times and she starts first kick, I don't race it.

Never believed in all the top synthetic oils much, but I would use them in a turbo powered engine.

From all the people I have known who used the first type of Mobil 1 oil type back in the beginning, in cars that had roller lifter problems at bugger all miles up when they buggered up. sure it sounds all good and people think one is mad not to use the best synthetic oil you can, but I don't believe all the hype and spin, but when a oil is tried and true you know it's good.
Castrol made a car engine oil that was advertised full on in the 80's as being the best thing, but from what I believed and seen of it was that it chewed cams and lifters badly, it may of been good in all other ways but not with lifters and cams.

Thinking back to the late 70's and 80's with the Honda XR's when they came out and the oils we had back then, I don't remember any problems with the oil back then but for only using more when it got real hot.

But when it comes to 2 strokes I am all for synthetic oil in the fuel and liked the Castrol TTS the best.

I don't believe in brands of oil or such products, I find what I believe is a good product and stick to it, chain oil, air filter oil etc.

When I blew a main bearing in the berg I knew that that engine was not built correctly, many said it's that crap oil you are using, but no that engine would not rev out cleanly wanting to shake it's self apart like the old Holden red 6 cyl engines would do if not fully balanced them and you rev it past 5500RPM.

I thought it was that the crank was flexing in the berg due to such a big piston, jap 450cc bikes don't have such a big piston and I am sure the piston weighs more because of such, so I believe that the mains need more room to move about like so they don't nip up and try bust out when they flex.
The 650 with the forged bell crank has no such issues with main bearings.

The Holden red had issues with the two piece balancer. The outer would shift on the rubber that was supposed to absorb harmonics.

All engines have harmonic issues as some point in the rev range, the Holden red blue and black 6 was at 6200RPM even when fully balanced you can feel it complain.
The Ford 250 6cyl harmonic issues came in at 5600RPM.

So with the single cylinder bikes is there an issue as such ?

The harmonic balancer is not just to do with the rubber ring bit.
