I recently bought a fury with a ys80 in it. I have not pulled the engine to see the condition inside yet but I'm assuming it will need a rebuild or at least some new bearings. I was looking at the boa bearing site and they have 10 different bearing sets for this engine. What is the best set to put in? Normally I just buy the most expensive ones,because they must be the best. In this case the best set of bearings are $95.00 and 100 for a piston and liner and I'm just short of the cash to put a new ys 91 in there. So again I ask which bearings work well in this engine?

ys 80
hey wow thats a good question, I have 3 YS 80's and I love them!!!!! I sold a brand new (! to my buddy , I like the 80 better anyway, Boca offers several bearings and you have to be carefull, Id recommend you buy the original bearings from YS out in Nevada, if he dont have them call Ron at Ricks RC helicopters in Texas he will have the originals, what I have ran into with Boca is they are a comercial bearing company and they will sell you the best bearings available expensive but good I hope this helps you

You will not want the original YS 80 bearing which was an all metal cage affair that did not hold up well.

Order a current generation set for either the 91 or 120, and you will have good results.
