Reply To: Bike doesn’t have power – Hyosung GT125
Hey, So its just best to find a good used engine from what I gather.
I know that the compression test has to be done at operating temperature, but since I have to buy one second hand and I cant test it at that temperature before because its off the bike.
I can however do a cold compression test because the starter its still attached to the engine, how much compression does it need to have cold just to be shure that the engine its somewhat healthy?
I know they loss compression with temperature but mine had almost the same results cold or hot. So i gather that if at least the compression is good cold, I have 80% chance of being the same or little less when hot?
