Ok I used that e2s gearing calc and did this to find out what sprockets I wanted.

Stock. I ran this for a little while and it was fun for toting the front end through turns lol

What I was running. 13/42 20" rears. I've got a video of my cousin chugging my bike up a hill in 3rd and it only came on pipe for a half second. He wasn't comfortable with the twist throttle so he didn't get on it. With this gearing.

Same gearing. 13/42 but with 18" rears. I was looking at 4th gear speed because that's just what I was looking at. I'm not into flat out WOT running 6th lol left the rpm alone. Talk about stump puller here though boys.

13/38 18" still kinda low. This would be for when we get the trails opened up some more, quicker running through them but still kinda low,, I'll probably run the 13/38 with my 20's

And then 13/36 18". Almost back to exactly what I had with 13/42 20". Very rideable, now i COULD grab a 14 tooth front and run 14/38 18" and it would be quite a bit faster. But I didn't get that gearing. But I think the 13/36 is what will make me happy. I really just wanted to get it close for now cause I KNEW 13/42 18" wasn't going to work. Lol
As for sprocket types: THANK YOU. I bought a steel 36t not sure about the 38. I'd prefer steel over aluminum anyway. I don't care about weight because I'm not a full blown racer.
And the trails. They are super smooth. They've hardly been used in the past 14 years so they aren't rutted or anything, and my uncle uses them for getting to his food plots, hunting stands, etc so they have been mildly maintained.
Put it this way,,, we ran the blaster through them

I will still keep my 20's cause I don't get rid of tires. Especially tires that were ran for a month before the bike was pushed into the woods to sit for 13 years. They leak a little but they are still VERY good condition.
Thank y'all VERY MUCH for the input and suggestions and info and links!
