yea i know this but everyone i spoke too that have turned up at the dealership has had more speed than i have, ok jokes accepted for saying i'm fat, but i aint that only weigh 12 stone 8 so not the biggest of people, but why would it be slower when it came out just cant get my head around it

Make sure that whoever serviced your bike used the correct standard of parts, for instance if they have replaced your standard air filter with an inferior make then this may cause a loss of power and therfore speed.

have they adjusted your throttle free play maybe?

dealership told me they dont have an oil filter and thats why it needs first oil change at 600 miles

seems a bit strange not having an oil filter, but ask a bike tuner about it and they said check your oil level as this is sometimes a problem, so i did check it and found it was well over the max mark, well to be honest it was flowing out when bike was upright from the casing of engine, so i drained some out mad bit of difference but not that much.

So in all be warned your bike will be slower when out of first service.
