objusting the chain tenssion on Ktm Duke 

a currect chain tenssion protects the parts
from premature failior and prevents wornout of parts
a loose chain might cause saftety issues like falling off
braking and a shaky gear shifftng wiplash effect
follow the marks on the body
and reobjust if needed untill the correct tenssion is obtained
like share sub
