Hey guys I've got two 2 stroke waiting for me when I got home this evening one is a zeda 100 firestorm the other is the California motor bikes WC avenger the Phantom 85/yd100 killer. It's a long story how I got two engines but I'm very new to the hobby hopefully learn as I go the plan is I'm going to take my time and do the mods and upgrade the zeda firestorm for another bike later the WC avenger will go on the bike I hope I get tomorrow. My question is is the any pre install work I need to do do a flush on it with gas the top is off the engine grease anything? Some guidance would be much appreciated. Oh yeah I email the person a California motor bikes and asked him about the oil gas mixture for break in is 24:1 and I'm using 87 octane etonol free and mixing it with Valvoline non synthetic oil. Sound about right?
