I just replaced the cylinder head, rings and piston. So I don't think it would be that but I will check compression I am thinking it could be the seals. Thank you for the help

 

I agree w/OPT.
Curious, why did you do the new top end? Could the oil injection not be working?

 

I changed them because the people I got it from said the oil injection was not working but continued to keep putting regular gas it in so when I got opened up the the top end the rings was smoked so I changed it all rings,piston, and cylinder was running fine earlier now nothing

 

So did you fix or confirm that the injection is working? Run pre-mix ?

 

Running premix now
