Re: Living in the mountains/breaking in engine?
Actually, you should give it some gas while going down hill because the only oil that the engine gets is mixed in the gas!!!
Your engine will start to get more power as it breaks in.
I don't know how much you weigh? but I weigh around 200 lbs, & a 44 tooth pulls me up big hills with a running start... so, you might go with a 46 or 48T sprocket if you really think you need a lower gear.
Keep in mind that the lower gear you go, the slower you will go on flat ground & down hill!
I don't see any problem breaking in the engine while going up hill, just try not to 'lug' the engine, & use 24:1 oil mix for break in!
