Reason I ask is because I recently discovered the 2015 1299S I bought used in 2017 with 1700 miles on it had an aftermarket 14 tooth front sprocket, while the rear was the stock 39 tooth. Prior to the 520 conversion I did a couple of weeks ago I was having autoblipper issues, where it would work sometimes, but it was clunky at times or it took 3-4 tries to get it to work. It was so clunky I disabled it at the track... unreliable at best.
Well, my bike appeared to be bone stock when I got it so I assumed the sprockets were factory gearing as well, and went ahead and ordered the 520 conversion using the stock gearing. I realized the bone stock assumption was wrong because I pulled off an aftermarket 14 tooth. I put the 15 tooth on and went riding because it was super nice out and after a short while I realized my autoblipper is back to working as it should - smooth and reliable! This past Sunday I rode it 250 miles and all was well... have a new appreciation for the bike with a functioning autoblipper! I have zero idea how sprocket size would be linked to the issue and I'm wondering if some of you guys might? It's beginning to bother me, haha.
