does anybody know where can i change the seat on the kawasaki 300 and or get synthetic kawasaki oil ?

need to have a comfortable passenger seat as well.

anybody would recommend any place ?

thanks in advanceee

Just about any appolstry shop can do it.. Though I’ve never rode in the passenger seat I find the drivers seat perfectly fine...

synthetic kawasaki oil == known brand synthetic oil

No need for synthetic oil in such an engine. A good semi-synth is enough and chance as per manuf. schedule.

The diff is really noticeable ive been told

You will hear anything about oils. Consider you are just a 2L consumer, some car owners are taken by smart marketing for a lot more.
