ok so i have a arrow racing with about 200 miles on it and i want to put a 70cc airsal kit in it. How reliable would this be? The dude from the local shop said i should be fine as long as its getting enough oil. I was also wondering should i take out the shitty oil injection and go to staright mix? I have run mix in my old dirtbike, but now im on a thumper '4 stroke". What should i do for ratio if i were to run mix. One more question can i run 110 sunoco fuel or should i just go with the pump gas?
