'85 350X Chain issue

[Nodnarb]

Hi I bought a 350X a couple months ago, and the other day I was riding and the chain slipped off goin over some bumpy stuff, anyways for the life of me I can't figure how to get this new chain on it. I'm used to slipping the rear wheel forward and slipping the chain back on and putting the wheel back, but it doesn't seem I can do this with my 350X...anyways yeah so if anyone could tell me how to put a new chain on and since I'm posting how often should I change the oil? Any help is appreciated thanks.

remove the front sprocket. put chain on rear sprocket and front and slide front sprocket back on.

The 350X uses the rear axle bearing carrier to adjust the chain tension. My best advice to you is to get a manual, it's all explained in there.

loosen chain tensioner put chain on front and rear sprocket, put master link on, readjust chain tensioner
