Hi,

If the distribution of y variable is not normal. (skewness equal to 1.1 and kurtosis to 8.2) can i run a simple linear regression of the y on x variables?

The validity of regression depends little on normality
of anything. The validity of the classical tests depends
on the normality of the errors, but the asymptotic
validity does not.
