Starting off on here after just completing my bike build and break-in so far so good but oh there were challenges.
I got my kit in a timely manner and put it almost all of it together on a Fixie bike from walmart. A real cheap setup that only cost me $200 with everything all put together except that the gas tank threads for the petcock were bad. so instead i ended up taking an old 60's yahamah motorcycle tank and ducktaped it to the frame heavily.
So far the engines stayed together but the bike itself is rattling itself loose and i end up retightening everything after everyride of about 30-50miles, so having a toolbag strapped to the bike is a must.
So far no major engine trouble yet still running a 16:1 gas mix(8oz of oil), next gallon will be a 20:1 mix (6.4oz of Oil).
