This will not work for you, unless you're trying to gain low end power and lose speed.
I'll find some specs for you.
Okay, your gear ratio is 18.04 with 26" wheel, 44t sprocket and Happy Time engine. At 6500rpm, your bike runs 27.9mph.
If you installed a 24" wheel w/44t sprocket on this same bike, at 6500rpm your bike runs 25.7mph.
With 26" wheel and 40t, bike runs 30.7mph @ 6500rpm.
With 26" wheel and 38t, bike runs 32.3mph @ 6500rpm.
