Okay I just did an inspection for my 2000 Ninja zzr250 bike /7k on it. They said I should do a tune-up since my compression readings were a bit low.
Here are my numbers:
Cyl #1:110 PSI
Cyl #2: 130 PSI
My numbers should be around 142-218 PSI. They said that with the tune-up they will adjust the valves to correct the low compression readings.
I was about to do it but there was a long wait for it till next week. Should I need to worry? Are these numbers way below average?
Could I do this myself?
I have a car and I have had it for like 4 years now and with like 1 tune-up? It runs great though, I just do oil changes. Is maintenance totally different on bikes? I should tune it up every 6k?
