Currently running in my twister, hope its a good month to do so.

My old timer friends told me to run below 60km/hr for the first 3000k. After 3000k run below 80km/hr for another 3000k. After that you can go all the way to the max. I have done it before and the bike seems to be running very well... but don't flame me if something goes wrong for you.
