Big bore kits for fc450

[madmini660]

Hi im new to snowbiking and was reading about big bore kits in snowbikeworld and I've always had big bore and turbo sleds and I'm trying to find a big bore for my 2014 fc450 that people are having good luck with any help would be greatly appreciated
thanks

my experience (much like 2 strokes) is that simply increasing the bore doesn't do much. I would be looking for fellas that are making significant changes to the valvetrain as part of their solution.

Ditto. I wouldn't waste my time on a big bore again. My buddy also just ditched his and went back to stock.

Keep it stock, warm and a good air supply and shred it!

Less motor work, less problems. Keep it stock and rail that bitch.
