I always warn folks about factory remans. The 185 I bought recently unfortunately had one. So I knew it would need a top end. TCM is so cheap they re-used old intake valves, exhaust valves you expect to toss at 1,000 hours, but intakes should go the distance with a quick grind. Well these had seen more than one grind in their hard life. They were not even hitting on the bevel, they had worn past that and where sitting on the top of the seat! The factory can re-use old parts that any legitimate re-builder would toss and use new, that and use unskilled, locally licensed labor. So beware, the term factory also means cheap, shoddy product.
