So I bought a 87 xr200r for 200.00, it needed a clutch cable. After getting this fixed the bike is running rough like its timing or something is off. So with me being new to the whole bike thing and this being my first ever bike, my question is, is this worth fixing given that I only spent 200.00 on it? The rest of the bike is in pretty good shape. Would it be easier to try and find another engine for it or fix the existing one? Also last question is, if this motor is shot then what other motors could fit into this bike besides obviously the one that came with it? I know these questions are pretty generic since you dont know what is wrong with my bike but I am looking for opinions because I am completely new to these.
