before i broke my quad down i was having a problem with my rear end. figured i would share my issue.
my rear end had major left to right play. figured it was my lock nut. tightened it and still the same issue. replaced the lock nut because i thought it was too worn and could not get tight enough. i replaced it with a Jensen/Outlaw type lock nut. it tightened things up but now the rear end was binding. so i took it all apart to find this:
the sprocket hub looks like it was missing a pressed on zink spacer. the spacer should ride on the race of the carrier bearing. check out the difference of the old and new sprocket hubs. both sprocket hubs are LoneStar parts. what happen to the old part? i have no idea.
because of the missing spacer the hub and the carrier was binding. the wear is shown here:

while i was back there i figured i would change out the old LoneStar carrier. Burgard had carriers on sale for $99 shipped so i jumped on it. took a month to get to me. i consider myself lucky. Burgard has the WORST customer service. be warned. ive heard stories of people not even receiving parts after payment. i like this carrier because of the chain adjustment. all you need is a 3/8 extention. also the grease nipple is on the outside. not on the inside like most carries. installed:

another part i installed was a LoneStar 450R sprocket guard. its S/S so it will take a beating. i ride 98% MX so a skid plate is not needed. i feel better with something back there. picked this part up along with the wave rotor from Troybuilt. THANKS BRADDA! also new pads so its all fresh in the rear. if you in the market for a sprocket guard, 250R, 400EX, 450R, and 300EX all have the same sprocket bolt pattern.

looks cool but i am kind of sketchy of how close the chain rides to the guard. i heard of chains getting de-railed on dual sprocket guards so one side may be the hot set up. still it rides so close. i may space the guard over "just in case" anyone shead some light on this topic? maybe i'll call LS or GT Thunder and for clearance specs.
thats all for now kids. looks good to me. hope you think so too.
Shaka BRADDA!
