Engine Knock

I've found a 1983 Honda XR350 that I could get for not much money, the problem is the present owner says that the motoricon1.png has a knock.  It starts right up but has a knock.  Should I run for the hills or take on the challenge to fix it?  Without getting into the motor, can anyone tell me what repairs I would probably be looking at?

Thanks, 

Might need major rebuild, but might just need oil change and higher octane fuel.

Is it a knock or timing chain clatter

I haven't heard it yet, I'm just repeating what the present owner has told me.  Do these bikes have a tendency to have timing chain or other common issues that might be the noise he is hearing?

All bikes can wear out a timing chain. Just guessing cause it's an 83 and probably stock Cain and tentioner maybe tapit screws r loose

How big of a job is it to replace timing chain and tensioner? 

Consider this..Parts for older XR/XL are getting hard to get..Eyeball the fiche below..parts you want or may need are no longer available from Honda.

My advice..leave it behind.

I have an 89 Xr 250 just rebuilt the hole motor. Even valves. But I used Wisco piston cause I had to go 77 thousandths. The only part I can't get is the tool bag
