i always thought i didn't maintain it properly but it's in good condition
yes i do service my bike. the bill usually came around 1000-1200.
2 local mechanics said only 2.5 liter engine oil is needed but i always had a bill of some 3 liters
at the service center.
i last got the bike serviced in october last year and since then i think i rode the bike , i think some 1500 kilometers.
but will change the oil in this month and get it washed and serviced
but this time from outside.
