As soon as the engine has passed the recommended break-in period, change the oil and run synthetic if you wish. You could probably switch at your next oil change.

As for the scotts oil filter , haven't tried one but would you rather spend the hassle of cleaning it and not knowing if it is perfectly clean, or get a $3 paper filter eveytime you do an oil change?? Paper ones filter better, plus

$70 is about 20 oil changes worth of the cheap filters.

After the first ride, (50 miles) I starting using Ams Oil full synthetic.

I haven't used my Scott's filter yet.

On my first oil change at 180kms/112miles. Stuck with the Yamaha paper filter as no Scotts here, but had one in my YZ and never had an issue. Running Shell Advance Ultra (good enough for Ducati in MotoGP - good enough for me) fully synthetic in the WR. Ran Amsoil in the YZ (can't get it here)

I would leave it a bit, the rings need a bit of time to bed in properly.

Give your bike lots of throttle mate, it will reward you with more power and less ring blow-by.

Mutu has it right. An aggressive break-in is the best way to do it. If you baby it the rings won't bed into the cylinder properly. As well, the oil formulas made today will last much longer than 50 miles and I also feel that the "every other ride" theory is too soon. 500 miles and a good quality throw away filter is more than adequate protection and they do filter better than the stainless reusable type. Super hot climates might require a little sooner, but not much. And while we're on the servicing subject, those who preach more frequent oil changes after extra dusty rides must not using/cleaning their air filters. That or they have stock with the oil companies. Don't fall into the trap of changing your oil every half hour. I have many years experience building race motors and I promise you many years of trouble free riding following those easy rules.

Cheers
