Striped FRONT Sproket SPLINES

[HELLONWHEELS]

Well i finaly got my 200x/m running and working good when i striped the slines on the front sproket shaft so i think. I took it all apart and the threads are worn pretty bad but dont look to bad , also the chain was lose. I could see the shaft just spining on the sproket. Any one know how to fix this or do i have to bye a 200m botom end?
thanks alot

you could possibly weld it but if you have to replace it you are **edited**.

I thought of that but i hear that the welds break pretty much right away?

[team-red-rider]

not if theyre done right like my old atc110 the sprocket was welded untill i found it...now i fixed it right good ol' service honda

[HELLONWHEELS]

Do you mean have it in place when i weld it?

[200x Basket]

so do you have a 200x or 200m bottom end? if it is 200x then i have a nice bottom end that you can buy pretty cheap.

to repair it you will need to split the case and change the shaft. the cheap fix is a welder and if done right that can last many many years.

its a full 2oom motor and i have no clue how it got so messed up..Witch would be cheeper/easier, changing the botom end or just the shaft?
thanks alot guys

Easiest: Weld a new sprocket to the shaft ( as 200x Basket said )

If you don't want to weld it then the easiest way ( without welding ) is to change the Bottom end out.

The hardest would be to split the cases and just change the shaft. It's a very time consuming proposition.

Alright thanks alot for all the help guys!
p.s i hade it welded but the guy who did it didnt even know where the on switch was on the welder and the welds broke. Ill get a pro to do it and see how it lasts.

I bought a 350x motor from Bill_X_R at about 4-5 years ago. The reason he sold it was the front sprocket was welded on. That motor is in my main 350x and it has held up great. So a good weld will hold up for a long time. ;)

Thanks alot Howdy and evey one else.

make sure yout sprocket is in good shape before you weld it because you dont want to grind the weld off and re-weld a new one on because the teeth are worn. good luck

Thanks alot guys for all your help looks like i found my answer

If you need a new sproket to weld on there, I have 2 new ones for 200x, 5 bux a piece and will charge actual shipping.

[HELLONWHEELS]

I dont think ill need one mine looks pretty good. But i'de like to get a rear one. I know i shoudl change both but the front and the chain is new so...

[IrvSLedman]

haha funny story, i had to do that to my 200 today, the splines rounded and i tried to use the bolts and plate... no good, so busted out with the arc welder, that suckers on there for a good long while now.

[chris200x]

this all seems way to familiar...

I went through this fiasco as well with my 200x. Isn't there a little play in the front sprocket for a reason. even if the shaft is not stripped? Welding it isn't the right thing to do. your just postponing the enevitalbe.

Well i found a base for 50$ yesterday so when i get some money im gonna get it but as for now its gonna be welded on there again.
