ltr 450 timing chain on an ltz 400?

[goodolboy32]

a friend of mine rides nothing but honda and on a recent rebuild he read on a honda forum that a honda 450 timing chain works on 400ex! the reason for using it was because of it's double roller style design!(stronger) is this possible with an ltr 450 and a ltz 400? i'm doin a rebuild and not sure the best route. just wondering if an aftermarket chain is as strong as a stock 450 chain, if it works? just curious!!!! thanks!

Never heard that before !400EX and the 450R are different motors

no troubl with breaking chains or anything but i have small top end chatter that goes away when bike gets warmed up! i'm getting ready to at least cheack my valve clerances before i go to crazy!

p. s. i know the two are different motors but wasn't sure if the timing chains both were the same! on my buddies 400ex he used a crf450 timing chain!!! the crf450 chain was much beefier but ut used the same gears and every thing of the 400ex motor! and yes the crf450 dirt bike timing chain fit in place of the 400ex's timing chain. both chains fit but the crf's chain seemed much more durable! i guess that was a bigger issue on hondas than suzuki's? thing is i may just have a valvbe clearance issue!!!

Thanks for the help and i'll update as i move along!
