Do any have any experience replacing 2001 Big Bear 400 Front Differential Input Shaft bearing and seal. Getting ready to buy one but the seal and bearing are bad. Any help would be appreciated.

I’ve got a 2000 400ex with a dg slip on muffler, it came with he stock muffler on it but the previous owner had the dg in a box so I put it on. I’ve been riding it for the past month and a half and every time I let off it backfires, and the other day the backfires got way louder, 2x louder! I’m concerned that I may hurt my motor? Why does is backfire??? Thanks

My name says it all. I have a '03 Honda Sporttrax 400EX with a new aftermarket carb on it that seems to be having issues. I can start it but it idles really rough and when I give it throttle it just kills the engine. I have tried adjusting the idle screw but to no avail. I am in the San Diego Ca area.
Any advice will be greatly appreciated. I would also like to get an owners manual for the thing too but can't seem to find a downloadable one.

So I’ve got a 2000 Honda 400ex absolutely love it!! I’ve had it for about a month, I ride with bruteforce 750’s, outlander 850’s and 1000 sxs’s and I was thinking of getting a trx450r carb and a full hmf exhaust. And probably doing the air box mod too, how much power would this give my 400? Just a little different or a big difference? Cuz if it’s not much of a different I’ll just stick with my dg slip on..... thanks!

Pulled my '86 Moto4 out of shed where it sat for 20 years. I knew it smoked. checked it over a little put in gas and it fired right up!!
Drove about 100 yards, ran about half throttle wouldn't idle. Put on somenew parts, jug/piston and rings, carb and valve seals.
'went together ok, tuned it over by hand about 6 revs whick went well. Hit the starter it fired for about 6 revs and quit. tried it again fired once and then th sound of something slipping like maybe chain slipping over spoket.
Took cover off to watch cam sproket, hit starter again, heard same noise and the cam sproket was not turning but jumping a bit. Chain was still tight. You will probably tell me I need to split the lower case but hoping there mightbe something else.
I don't fully understand the chain tightener, the plunger only moves about 1/4 inch, should it move much more than that when off the motor and compressing it by hand?
Thanks for any thoughts.
