Chazillor Posted June 29, 2013 Share Posted June 29, 2013 Hi there, is there a rough mileage at which you would expect to want to be replacing the cam chain/tensioner? My ybr is coming up on 17k and I'm starting to hear what I think is a bit of ticking, the valves could probably use checking but they won't be massively out as I only checked them about 5-6k ago. I change the oil every 1500 miles so it shouldn't be a lubrication problem. Any thoughts would be appreciated, also is there anything else I should be thinking about at this sort of mileage? Cheers Link to comment Share on other sites More sharing options...

Not sure about the YBR but most cam chained bikes have adjustable tensioners. You could look at this as well as getting the tappets spot on. Make sure you have the correct procedures to do both of these. It is easy to get both wrong. Link to comment Share on other sites More sharing options...
Prichard XT Posted July 3, 2013 Share Posted July 3, 2013 I thought the same thing with my XT but when iv been sat next to a friend on his YBR the engines sounds exactly the same and his and he'd only done a few 100 mile since getting it from the yam dealer at this point id done 35000 mile try not to worry to much Im sure they use springload tensioners on the YBR & XT in the service manual check for the tensioner is to remove tensioner (two bolts either side) remove end cap on tensioner and insert a thin long screwdriver in the the opening and gently push you should feel no resistance by this I mean should not catch, feel rough or grip when checking operation hope this helps Link to comment Share on other sites More sharing options...
