Trading for 560 predator?

[QUICK04Predator]

Alright so i have a 2005 Yamaha YFZ i just traded a truck for. The YFZ is BONE STOCK! im talking original tires from 2005! LOW HOURS and pretty clean to. I am thinking very strongly about trading it for a 2004 Polaris predator with the 560 big bore kit, Hot cams, K&N intake, Big gun exhaust, Shaved front and rear fenders, +2 full flight A-arms, and it has neon's or something stupid (neon's are coming off as soon as she gets home so dont worry!) Lol But i know I am on a Polaris site so everyone is going to say do it but i want some hones opinions! Thanks guys!

Unless they have receipts to prove this was done professionally and not in someone's backyard.

I typically steer clear of machines with these mods because they usually heavily lack any reliability.

I need proof it was done right. Otherwise I would skip it and stay with a stock machine otherwise.

Alright, why would it being bored out make it less reliable? I'm not disagreeing just wondering.

Being bored out wouldn't make it unreliable. It should be just as reliable in theory as stock. I always question the quality of the work when someone takes the motor apart.

I want to see receipts for the labor so I know who did it, or I want to know that the owner knows what he is doing when he did this.

I always assume the motor is going to grenade, and need to be proved otherwise. At least thats my rule when looking at used machines with internal mods.
