At 300 miles phase one of two of my bbk break in is complete! So I did my second BBK Oil change today. I hit 300 miles total on the bbk and everything is going great imo. After upjetting and getting the uni there's a noticable difference in just about everything, torque, acceleration, overall power and performance. My MPG seems to have suffered of course but I haven't measured the before and after so all I can do is guess. I think my variator weights might be limiting me because I can no longer go over 45mph on flats ever since I got the koso variator and swapped to 9g weights, I think I could stand to go down to 8 or 7, but I'm still not sure of the safe range of weights for a koso variator and bbk. I dumped the oil from my last oil change into a coffee container and took it to the local oil change place and they got rid of it for me for free. While doing so I noticed all the metal shavings that I've been looking for this whole time. It appears that there was some metal shavings from my 100 mile oil change, just not a lot and I couldn't pick them up with a magnet (even though the inside of my cylinder wall reacts to magnets ) I'll be taking pictures of the oil and metal bits in a little bit. ;D

Very little amount of metal bits. There were more the first time I changed the oil and some of it was shavings. This time it's just some tiny metal chips and there's only so many that they all fit on my finger tip. Most of that crud in the oil is stuff that either came out of the filter or mostly what fell from the trees as I changed the oil and let the pan sit there to cool off. No worries there.

So is it normal to get some metal bits in the oil on the first few oil changes of a BBK scooter? I don't think I saw any shavings in my oil

[replyingto=domindart]domindart[/replyingto]Yup. Some metal shavings is normal, copious amounts of shavings means something is horribly wrong. I think this counts for breaking in any engine, but having no metal shavings is probably the best

[replyingto=newbscootdude]newbscootdude[/replyingto]Alright, so you need DYNO based oil, NOT Synthetic (although this is arguable, it's probably the best to use non-synthetic when breaking in an engine). Any 4t motorcycle oil should do. 10w40 is standard.
You need to change the oil at 100 miles, 300 miles, then 600 miles. If there's still metal bits after 600 miles then you need to change the oil frequently, like every 100-300 miles, but if there are no metal bits then you continue with the regular oil change schedule of about 1000 miles.
