As has been said.
For maximum life, I always change sprockets and chain together.
15/39 seems pretty good for a 999.
But if you just want a lower gearing and have a factory chain and 15/36 now...
Why not change the front to a 14T, run 14/36 until it┤s dead and THEN change everything to your 15 front, 36 rear and a new chain.
Spending money on a new 15 front and new chain now.. Seems to me like throwing your money away for no reason.
You could ofcourse increase the lenght of your chain. But be sure to let someone put a riveted chain coupler in, not the clip-coupler. And don┤t put them in beside each other, but with 10-15 links inbetween.
