Don't put on a 34T rear. Put on a 15T front with the standard 36T rear. It will drop the revs per mph. You will find the gearing much better through the range. I live in a fairly hilly area and regularly get about 95 - 100 mpg. (UK gallons).
I currently have a 15t and 36t set up on my bike but I’m getting roughly mid 50s mpg (us gallon) but I’m doing a lot of highway speeds. By my math you getting 95 Uk mpg equals 114 us mpg so I’d love to know how your getting those insane mods numbers because I’d love to get mine that high.Don't put on a 34T rear.

How does your bike do with that sprocket does it get pretty good mpg? Does it really suffer on accelerating? And how does the aluminum sprocket hold up?Yeah I had one on my bike, I think I got it from PMP sprockets in Texas but they dont seem to come up on a google search these days, it's around 8 years ago I got it.
These days I'm using Vortex sprockets and here's the link, just gotta put 34 into the size box.

Your correct, not enough room for a 16T and I think this would be a bridge too far with a final drive ratio of 2.25:1 and only 31HP. I was probably pushing it with the 2.26:1 (15/34T) set up but got away with it cos of my light weight. Stock set up is 2.57:1From my experience swapping in a 15t, it doesn't look like there's room for, say, a 16t. A cs sprocket would be cheaper than a rear wheel sprocket. The larger cs sprocket would be easier on the chain from what I've read in the past. The Sprocket Center in Fountain Valley Ca. provided my sprocket.
