Bonneville America Forums Forums Technical Forums General Tech Another sprocket question

Wanted to ask you guys who have moved up in front sprocket size how much of a difference in rpm range does going up a single tooth make?I'm sitting on close to 20,000 miles on my original 16/42 set and figure I will probably need a new set by spring and was thinking of going to 17/42.

200rpm's per tooth, through out. That's my experience and I'm running a 19t right now that gave me about a 1 mpg improvment.

Thanks Chip that's just what I was looking for.
