Breaking in a bike's engine - I

From another forum guy:
"well i had to go through break in period with 4 bikes...2 kawi's, 1 suzuki and now 1 honda. every bike had certain rpm's that was not recomended to go above. i have always followed recomendation on rpm's and mileage. i had problems only with first bike (kawi). it's engine blew up under me in a highway on about 125 mph. it blew up not because of wrong breaking in but because it had some serial defect from the begining. first 1000 km (about 625 miles) in the engine should be non-synthetic oil (usually it is mineral oil)because non-synthetic oil is less thick and that way it allows parts to brush more into each other and break in (not break ). because non-synthetic oils are less high temperature resistant that is why you shouldn't rev it too high. if you do then you make temperature of the oil and parts go too high and oil will be less and less thick and will loose it's abilities to moisture and cool down parts. parts will brush into each other too much and you can literally kill ur engine. there are different methods of breaking in from manufacturer to manufacturer. on kawi 636 first 800 km you shouldn't go above 4.000rpms and next 800 above 6.000rpm. on gixxer 600 first 800 km you shouldn't go above 7.000 and next 800 above 12.000 (i think, i dont remember anymore). on my blade they told me not to go above 6.000 rpm's in first 1.000 km. after first service interval (and puting synthetic oil) they told me i can ride it as i like.

so there is no need to complicate breaking in period. just follow instruction from your manual or what they told you in shop. don't be afraid of loosing power if you ride it less agressive then you think you should. today's bikes are powerfull enough and on regular roads anybody here can't use 70% of that power so they are more powerful then we can handle.

and don't rev it to fast...i mean let your rpm's go smooth. don't open throttle too fast...that is in break in period"
