1990 yamaha zuma

[dwint51]

I know where I can get a zuma for 300 but it doesn't run.its in the shop and I asked the mechanic whats wrong with it and he said it needs rings.there is 5000 on the speedo and mechanic said he replaced the coil ,stator and belt.being a 1990 I have my doubts on who is telling me the truth.it has a bbk kit on it and already it needs rings.it has brand new tires also.i know the mechanic so maybe 300 wouldn't be a bad deal.plastic is all good also.i can do all the work myself so it wouldn't cost much to fix if it is rings.i would put a new bbk kit on it anyway but it has a vertical minarelli that im not familiar with.does it sound like its worth it?
