Thinking of repowering with a new 250. Been pretty quite lately or I haven't been paying attention . Any current issues like Yamaha had with making oil etc? Would 2020 be the second year of production? Is the performance as good or better than the 2 stroke? What's the warrantee I think I saw three years but I thought I have seen peaple mention five, I'm not in a hurry are there speacial warrantee thinks they offer? Thanks to all the smart bbc folks.
