23+ 350 gearing

I ride alot of sand on mine and i feel like the stock gearing is about perfect.

I like 14/53 gearing on my 24 350. 
Mostly ride sand tracks.

We like switching to 13 front. Cheaper, easier. Closes the gap between 2nd 3rd. Sx and xcf models

Go up one tooth in the rear. -mxa

I think the 23+ 350 is about the only bike they don't recommend the +1 🤣

For me +1 help a lot. It is something you have to try..
For me I felt like I needed little better/quicker pickup when using 3rd gear in corners. Im light weight and I can get away with using 3rd gear in most corners. If you use 2nd gear in corners then adding a tooth wouldnt help..

I actually did the opposite. I felt like every track I was in 3rd and 4th gear only. 2nd gear was way too short and half way through corners I would need to shift however if i tried to use 3rd to enter it didn't have enough grunt to roll through the corner without the use of the clutch.  I went to a 50 tooth. I use 2nd in the corners and 3rd in the straights. It also shortened the gap between 3rd and 4th. I have to shift a bit more but to me the power is much more on point where i need it. 

Stock gearing wworks good.
