rhino 700 motor rebuild

hi everyone, looking at some info on rebuilding my rhino. I bought this 2008 with a blown rod so planned on a complete rebuild. The info I am looking for is where to stop. The rhino came with a 734 piston bb kit but now I am thinking of the 780 kit. I was also planning on an EPI clutch and also a new ignition to take away the rev limiter. I was talking the other day with a Yamaha expert, (Chad at CR Racing, mostly turbo sleds I believe) and he said I need to watch out with the big bores as they will overheat. I do not want to get that deep and have to start changing the rad etc but want a reliable sxs with some power and speed behind it. Is it worth the extra for the 780 kit or just stay with the 734 and new clutch etc.

TIA Doug

Pete & Roberta

I would keep the rev limiter especially with a built motor. I have an 09 700 with cam, bored throttle body, duel muzzys, efi intake and and msd fuel and ignition programmer. I could bump mine up to 8,500 rpm but i set it at 7,800 for reliability
If ur worried about over heating put a fan override switch in it
