HEY

ive got a 90cc 4 stroke 03 model dirt bike and its got low compression (wont start) ive recently replaced the spark plug because it was blown and it made it a bit better but still wont start i can get it started by clutch starting it down the street but it takes a few times before it kicks ova and once started it blows a lot of smoke (blue lokking colour) and one i start reving in higher revs it sounds quite rough and shakes a lot
 
i know its low on compression but i dont know wat the actuall problem is
 
Done a ring mate, burning oil, keep using the bike and it will only damage it more.
 
kk thanks very much for that cause im new to moto mechanics so i dont know too much myself
