Wearing them out is not the issue; some have lasted 75K miles before being worn past the service limits. The service manual recommend replacement when 50% of the wearing surface has been consumed.
The problem is failure; chipping, breaking and/or premature wear. I have two bikes, the tensioner were very near failure on the '05 at 12K miles when I upgraded to 95" with cams. The inner tensioner on my '02 was OK at 25K miles but the outer was worn down to the metal when I tore the engine down to build a 107".
A catastrophic failure can result in oil pump failure which can result in an engine melt down. The damage done depends on the failure and how quick it is caught and corrected.
At 35K miles, you should check yours but I would at least replace them with the CYCO tensioners and upgrade the inner cam bearings as well. Heck, while you are at it, install a set of SE204 cams.
ESP should cover but why go through the hassle and downtime.
