Default Chain Strech

Ok here is my problem i have a 94 900 and am a little concerned with the amount of time i seem to be spending on adjusting my chain it seems to have to be done every couple hundred miles or so only had bike for a little over a year and i replaced sprockets and chain one month after purchase. The chain now is past the replacement mark (not by much one line) but like i said this seems to be a little excessive to me. As for riding habits i do the normal dumb things like high speed blasts down the interstate the occasional wheelie, and your normal city stop and go driving. My friend told me that if i lube it all the time which i do that this speeds up the process of streching out the chain is this true? well any help would be great thanks for the help btw it is a matching set of rk chain and sprockets any suggenstion on what brand for next one as i will be replacing them soon just dont want to wear it out as fast as i did this one.

Actually the more you lube it the less it stretches, so keep it lubed and follow its progress. Make sure that the axel nuts are tight. Thats all I can think of.

Chains are really nothing more that a series of pins with bearings. If the bearings are dry, they will wear much faster, just like your crankshaft and main bearings if they were run dry.Also, like any bearing, it needs to be broken in, to get the most life out of it. With a new chain, treat it like a new engine. Lugging an engine is hard on bearings as it is also on chains. Quick and sudden throttle changes are also. Lube that chain every time you park it for the night, while the chain is warm. Wipe it off with a paper towel before you ride it again. Adjust the chain properly, not too tight, not to loose, but adjusted right. Do this after you lube it. Again, a chain is nothing more than all these pins and bearings. Depending on the bike, there is about 110 of them. So if each pin/bearing wears even only as little as.001 of an inch, that is approaching an 1/8" already. Think what it would be if each pin/bearing wore .010 of an inch!

spend the little extra for X-ring over O-ring they are way better and flex more.

This is for pedal bikes but same thing;
Over time, the link bushings wear. This is called 'chain stretch'. Initially the chain's hardened coating resists this process, but once the hardened coating wears off, the stretched chain starts to wear down the rear cogs and front chainrings.

Chain wear depends on many factors. Is the chain kept clean and well lubricated? Are you cycling in winter on salty roads? Do you regularly go off-road through mud? Do you cycle hard, stomping on the pedals? Are you using the gears correctly? Do you ride in one gear all the time or do you 'spread the load'? Are the gears, freewheel and chain-rings worn? Is your chain compatible with your gears and freewheel - e.g. super narrow 9-speed chain with 9-speed cogs?

Due to all these factors it's not possible to give you a length of time, or mileage, over which a chain will last. One approach is to run 3 chains and swap them regularly to maximise the life of the whole drivetrain. This is sound in theory and works for some people, but it does sound a tad obsessive. Our recommendation is to use a chain checker. This is a tool which accurately measures chain stretch and alerts you when it's time to replace the chain BEFORE it wastes the cogs and chainrings.
