Response to oil change intervals
4000 sounds about right to me for the gsxr
As ever, optimum oil change frequency depends on how long you want the bike to last, what kind of riding you're doing and what kind of oil you're putting in.
cheapo oil, short commutes thrashing the hell out of it and wanting the bike to last = frequent oil changes
good quality oil, long gentle(ish) rides and not worrying about how long the engine will last = not very frequent oil changes
You pays yer money and takes yer chances!
