Re: Timing Chains - JP Performance or Rollmaster
It would depend on a lot of things like vavlespring pressure for example. One of my sets has done 30,000k's and is slightly stretched. It was running 335lbs open for 24,000->25,000k's. The last 5000k's were done with 380lbs open minimum.
The other set I had I wouldn't know how many k's but if I had to guess I'd say around 50,000-80,000k's as it was a daily driver that travelled around Tasmania, South Australia and in the end Victoria.
