As to the years it should last who knows?? As long as it's lubed, dry and rust free it could last you 10 or 20 years provided you don't use it all that much. So 3 years all that long but you need to look at the mileage and chain stretch more so. Clean and lube the chain every 400-600 miles, adjust the tension at the same time (per manual), lube the chain if it gets wet and like Muller said 20k miles is very possible to get.
whats the best way to get to the front sprocket area.. i noticed it while i was cleaning my chain, but didn't put much thought into it. i can only imagine the amount of grime is in there
3 - 8mm nuts takem off, then pop the sprocket cover off, clean the gunk, while yer in there, check the clutch adjustment
Yeah pretty much, easy as falling off a tree stump.
