So I Might be trading my 1996 CR125 for it, it's a 07' that was ridden for 2 months before it blew up. He paid 9g for it at the dealership, he ran 2 stroke fuel in it because thats all he had laying around the yard. I can get the parts dirt cheap online, I just gotta get a rough estimate on how many hours of labour it takes to split the cases, redo the con rod bearing, and seals. Also then of course reassemble the whole motor, tune the valves, etc. How many hours does it take a skilled mechanic to do? How much do you usually pay a dealer for a whole engine, parts included? My tech charges 50$ or so per hour, so I just want to know how long it usually takes to do what I said. Thanks!
