No errors have shown up, I've put 60 miles since this morning and all is well. I used the regular non-bumpered sprocket from JT sprockets because nobody seems to have a rubbered bumpered 15 tooth sprocket for sale, I looked everywhere.This is great feedback on the front and rear sprockets being both swapped out. I did somewhere that all the dashboard errors take more miles to show up. Keep us posted if the errors show up on your bike when you take a longer ride with it. I changed only the front to a 15-tooth rubber bumpered sprocket (the bumper keeps the noise down) and it made enough of a different that I like the bike better. The errors showing up does seem to happen on the older X300 and there is one other owner of a 2021 that did both sprockets saying that there is no problem. Did you put a rubber bumpered sprocket on the front? I'm interested in knowing if you can hear the difference going to a non-bumpered sprocket.
I'm made a lot of modifications to my 2021 X300 so if you plan on putting on more fun stuff check out my channel. The most viewed is the "Full LED light swap out on the X300". Be seen and be safe. My most fun upgrade is the Denali Soundbomb Air Horn as it now sounds like a truck instead of a sweak coming out of a duck. lol

I don't hear anything different with the new sprocket as far as noise goes, sounds the same.
