Finally got all my parts and I am going to swap out my compensating sprocket and clutch basket and take my bike from a 3:17 to 3:37 gearing. I cant wait to ride it. I let everyone who is thinking about this also how it feels and gas mileage afterwards.
I got my primary gearing swapped out and rode to Daytona with some friends. Initially I felt no difference, once we all started riding I noticed I was shifting alot faster then they were. Off the line I felt some improvement but nothing drastic. I read some posts where people compared this to a big bore kit, lets just say I hope not. My buddies stock 96" was still faster and my other buddies Honda vtlx 1300 was still faster. My wife was on the back of my bike so maybe if she wasnt on there it would of been different. Gas mileage was 42 mpg, so I was happy with that. That included bumper to bumper traffic and highway. When I go to my big bore kit in a couple weeks hopefully that will really bring out the gear swap.
That change in gearing represents about 6%, so you have that amount more torque at the rear wheel. Your analysis of 'nothing drastic' sounds about right!
I changed the gearing on my Dyna from stock of 3.15 to 3.75, a change of 19%. That is very noticable and worth a big grin! Living in the UK my Glide came stock with 2.94 and I changed that to US stock of 3.37, a change of 15% and also very worthwhile!
Changing gearing is very under-rated in the Harley world. I reckon a lot more riders should do it as it gives cheap improvements in performance.
