bogging down

I take it you are premixing and the oil injection is removed?

If so you should run 32:1

Also welsome to the forum bro..........
 
hey thanks guys its actualy my friends quad..i did pick one up three days ago but mine still has the oil tank..is it normal for the oil to go in realy slow??
 
on the stock oil tank, i always pulled the little foam things out with clean needle nose piers, then fill the tank and put the foam thingy's back in, it'll fill quicker when it doesnt have to filter down thru the foam
