I have a nut on order and think I have ID'd a 'gotcha' in case someone
considers sourcing one theirself. As I understand it, the nut from Jake is
relieved so that it straddles the splined area where the matching stock lock
washer grips the shaft. The nut therefore comes up against the sprocket and
the lock washer is not used (?). Perhaps another innovation would be to
keep the standard lock washer with a self-sourced, self-locking nut and NOT
fold over the washer edge (or use a plain washer that clears the splines
with its inside diameter). Someone that knows this area of hardware better
than me should critique what I say.
By-the-way, I have a report on the 14 tooth sprocket on my '03.
1) Highway & freeway use is definitely inferior to the standard 15.
Unnecessary higher rev's at the 65-region traffic speed. Higher speeds more
uncomfortable - always aware that the bike is not 'loafing' as it would be
with taller gearing.
2) In-town, stop and go traffic performance is much more relaxing pulling
away from stopped, trickling along with the flow. Third gear pulls nice
away from right turns where it bucked a bit with standard gearing.
3) On the trail, I tested the same ride with 15 and 14. So much better. No
snatch negotiating
tighter situations at walking speeds. Second gear becomes better too for
the slightly faster, but still tricky, trails.
Bottom-line, this dual-purpose bike needs at least 2 sprockets for different
purposes. I'm going to get a 16 too, for those longer cross-country jaunts
where I won't be going off-road. What's nice is that there is plenty of
adjustment range to work with all 3 front options.
By-the-way, not only Jake's nut for the sprocket if one is going to change
sprockets often. Get a locking rear axle nut too or quick-release, reusable
pin. The standard cotter pin set-up is a hassle and we are not supposed to
re-use them. Jake also has one-wrench nuts for the chain tensioning.
Lastly, no master link? One has to pull the rear axle to get clearance to
get the chain off the front sprocket? When did motorcycles drop master
links; was I asleep? Something to do with o-ring chains?
