hi guys, so basically, i found out on this 426 i got the exhaust bearing to the cam was fried, i went to pick it up by the bearing and wth all this slop! so it was time to go auto decomp... local dealer had some cams, so i sent my friend down, NOW from reading, im told 03-05 Yz450f exhaust cam.... correct? what about Wr's? i ask this because basically the guy told my friend (and its his dbike) that, that cam should work.... i notice size wize its a bit smaller i think on how big the gear is, like top of both gears is no longer nice and paralell but a slight grade uphill from exhaust to intake cam.... so should i run this cam? the Timing chain doesnt want to really sit that well into the teeth on that cam, its a new wiseco timing chain i had bought, but the stock intake it fits alright on.... so, basically the guy at the yami here that sold it said it would work, he said it was off a "yz450f" but didnt say what year... (could it actually be a wr cam?) . Anybody got any ideas? should i run this? the chain DOES bite into the teeth a bit, that i could see it working fine, but im just trying to make sure before i go ahead and do all of this up.... and find out it skips a tooth magically or w/e, THANKS!!!
