What's the best way to go from in phase to OOP? We've only had our tandem for about 3 months now and I haven't had to adjust tension on the timing chain yet. Is it easier to losen the EBB enough to derail the chain, adjust to OOP and then readjust the EBB? Or is it easy to just break the chain and then put back after adjusted to OOP? Seems like it would be hard to put the chain back together under tension but I've never tried.

Thanks for any help, I'm wanting to try OOP!
