I am new with this and have a lot to learn the last few days I search the site and read up alot.

I have a SL780 polaris it stand for a long time and the guy have it could not get it started. I get it going but there is a lot of oil junk coming out at the back is that normal?

My questions

I open the top and the sleeve look good few marks on the side but feel smooth. Can I just hone it and put new rings on?
I open up the carbs must I boil it in water or how do I clean it before use a kit?
What reeds must I put in?
I also need a LR 54 and a LR 23 were can I get it?

Thanks allot
