The 416 with a cam seems to be pretty reliable on my brothers 400. If your looking for more top end you will be getting a aftermarket cdi. The cam(depending on which one you get) and bore are gunna give you alot of torque and low end. Not so much top end. You could try going bigger on the front sprocket. That will give you top end. Also could get bigger back tires than the stock 20"s. These will all give you topend.

I found some works triple rates on e-bay cheaper than 450 shocks when i got mine. Maybe I'm just lucky. if you use 450 shocks get 08' or newer. people I've talked to said the valving is alot better.

The 450's from 06-current are exactly the same. The only thing changed are the colors and graphics.

Well yeah, but that doesn't mean that the 426 is better. I know plenty of people that have NOT had the heating issue with the 440. The 416 and 426 are more reliable but power wise they can't touch a 440.
