14 x 49 gearing - HOT...!!
Ramski:
14/47 is fine for me out here in SoCal. I have tried 15/47, but makes first tuff on nasty climbs. When I was in Arizona, 13/47 was good in the tight stuff, but had absolutely no top end in the sand washes.
kawdude:
I'm running 14/50 and like it. I'm tempted to try 13/50. Yeah I know thats low but I ride with my kid on a xr70. His high gear is too slow for my 1st gear so I'm constanly riding the clutch.

I like even numbers so I use 14/50. When I told my 125 riding buddy what I was switching to he asked me if I was nuts. My response was, "Probably". :twisted:
Rick:
Actaully, with a flywheel weight, running a ratio more like a 125/250 isn't that bad, as the weight helps control wheel spin.
As a test, I pulled the flywheel weight off last weekend without changing from the 14/47 sprockets, and just hated the change. The bike spent more time trying to swap ends than running straight. While I use the power to steer the bike with the rear wheel, it must be controllable to have the desired effect. We returned to the van where I reinstalled the flywheel weight, and then rode the same 20 mile loop. Much improved, so the weight stays.

Rick,
I had a 14oz stealy on a 1987 CR500. Made the power nicely controllable but also seemed to make the bike handle slower when swapping (leaning) the bike from side to side in tight corners. Did you notice this (or any other handling effects) at all in your back-to-back tests? I have often thought that something like a 4 or 6 oz flywheel weight would be about right. Cam.
