There are any number of posts on this forum dealing with chain and how to cut them. There are tools made to press out the pins in the rollers or you can grind off the ends of the pins and use a small punch and hammer to drive the pins out. When you install the master link make sure the closed in of the clip is facing forward on the top chain or the portion that is entering the motor. We could offer more help if you could post a photo of your bike and especially a good picture of your chain tensioner installation. Ideally you want about 1/2 to 3/4" play, or slack in the chain when installed. You measure that on the top chain with the bike moved forward until the chain sags. Less than a 1/2" is too tight, more than 3/4" and your chain is loose and can bunch up on the engine sprocket locking your rear wheel. Hope this helps you.
That helps me, I messed up my chain pretty good and finally about 10 minutes ago jury rigged it together with two master links. I rode down my driveway and released the clutch and started driving down the street, I got about 3 houses down and the wheel locked up. I had to walk my bike back holding up the rear wheel. Anyway tomorrow I'm going to the tractor supply store people have been talking about and getting that 10 foot chain.
I'm just glad my bike started if only for a few seconds.
