250cc compression what should it be??
« on: November 25, 2011, 01:01:40 AM »
hi i have an australian delivered 250cc bandit
the red vavle cover model with the variable timing

what compression should i be getting ?

i did a compression test and got the following figures but i have no idea if the figures are good or bad
from my limited knowledge i would say they are a bit low but with no workshop manual (which apparently doesnt exist) i have no idea if my numbers are good or bad

cyclinder 1 95psi
cyclinder 2 100ps1
cyclinder 3 95psi
cyclinder 4 100psi

thanks,

nate

Service Data (see Downloads section) mentions 1,000-1,500 kPa (145-217 psi), with a lower limit of 800 kPa (116 psi).  Mine rides at 140, 115, 115, 105.
