Chain questions

If I remove a couple of links and add a master link to a chain that has a few miles on it, am I going to mess things up?

I've got a DR350SE with approx. 15,000 miles on it with unknown mileage on the chain. I've added a smaller rear sprocket to it to gear it better for the highway, which necessitates moving to the last notch in the snail adjuster to get proper chain tension. I'd now like to carry a smaller front (counter) sprocket that can be switched out when I want to go offroad with it. This will def. make the chain too long. So, I'm thinking of removing a link and adding a master link to re-connect it. But without knowing how many miles are on the chain, or how much it has stretched, is this O.K.?

Any guidance?

You can measure the chain to get a good idea on how much it has elongated (they don't stretch ;-)
15" is exactly 24 links pin center to pin center, if you measure 15 1/8" elongation is about 0.8%, 15 1/4" is about 1.7 %, etc. A lot of the old MC manuals used 2% for a maximum before replacement but FWIW 1% is the standard in the bicycle world and I go by that...anyway if you read over 15 1/4 I'd replace the chain.

You should be fine. Just get the proper master link for the type of chain you have. Not all master links are created equal.
