I have a 4 inch sewer cover in my basement with a 1 1/4" cap on top. I can remove the cover but it is very diffucult with a wrench is there a tool or a method to remove this more easily?

I was able to remove my 4 inch brass drain line cover without destroying it using a 1 3/8 inch 3/4 drive socket. Many covers have a square (4 point) tip on the cap. 8 point sockets are also available to fit these caps, but are expensive. Pipe wrenches tend to eat up the brass caps and generally make a mess of things. Hopefully you could rent/borrow the needed tools to make life easier. A truck repair shop will have these larger 3/4 drive tools and may lend them to you if you offer them a healthy deposit to guarantee their prompt return.
I broke my cap loose by gently heating the cast iron pipe lip surrounding the cap with a propane torch and LIGHTLY tapping around its circumference with a hammer to soften the old pipe thread sealant. After it cooled, I sprayed Kroil (rust bust spray) around the cap edges and again lightly tapped with a hammer to help the spray to penetrate the threads. I let it soak in for half an hour and made a second application of Kroil and let it soak overnight. Next morning my breaker bar (and a short pipe) was able to dislodge the brass cap without any damage at all.
I was able to reuse and re-install my original cap, but if there is any damage to yours, just replace it with a new PVC cap. Also, be careful what you use to reseal your cap if you ever want to remove it again. A PTFE based sealant works best. I used "Real-Tuff" thread sealant by Hercules which remains soft, allowing easy removal.
Another tip for working with old waste lines: Don't bite your fingernails.
