Just ordered my new motor so excuse me if this is a noobie question. I've read repeatedly on this & other sites that it's highly recommended to replace all of the engines bolts. A couple of times I seen that a 8.8 grade bolt is recommended, beyond this I know nothing. I'm looking for specific size, quantity etc. of all the bolts. If my model is needed then I have a 66cc 2015 SkyHawk Angle Fire 2-Stroke GT5A. Thank you in advance for any help!!
