Hey guys, I’ve got an 02 Sportsman 700 with a spun bearing. So I’m trying to figure out my options here. I can get bottom end rebuild kit with the crank/pistons/gaskets/seals for about $900, but its with a re-manufactured crank. Or I can get a new crank from HotRods for $650, and piece everything else together for somewhere around the same price I would imagine.

I guess my big question is, and I’ve been really searching around for more information, can I rebuild the engine, with the 700 case and head, with an 800 crank/balance shaft/pistons? 800 parts are cheaper and easier to get, and I need to know if and what models/part numbers will fit into a 700 engine case. I know the bore is the same but that’s about it.

To sum up my questions again:

Will a re-manufactured 700 crank hold up to a new one?

Can a 700 be rebuilt with an 800 bottom end(Crank/pistons)?

If anyone can offer any kind of help or advice, I’d really really appreciate it. I’m pretty new to all this and am trying my best to learn fast. Thanks!
