Should i be worried

[kitman]

I am doing a few power upgrades to my 04 450, cam, rejet, k&n and i have a full yoshi exhaust. My question is should i be worried about my bottom end more so my crank?

those mods wont really have a negative effect on the crank if thats what you are getting at, the cranks do wear out normally though, if you have the money you might wanna throw a crank and bearings in it.

Don't worry about it. Run the bike with your mods. When the
crank or crank bearings go, replace with a Hot Rod crank and
OEM crank bearings. :D
