All bikes that I know of have fixed valve timing and 90% of the cars on the road. VVT is found in relatively few vehicles, some Alphas, Hondas, Mazda MX-5's and a few more.
The ignition timing on bikes is either fixed or electronically advanced and retarded by a control unit. I doubt this is your trouble.

1000km is about the right time to do the first oil change. Do the filter as well as any dirt or metallic particles from the assembly and running-in process will be trapped there.
it does not have a rev meter but assuming that i pushed it close to its limit to get it past 80+kmph that maybe so. if thats the case i will try revving an a lower gear to see if a similar thing happens, and if it does alternatively i will need to change the rear cog to get more smooth speed . will update post when i try lower gear.
