How about 1998



Surge Cures:

Techlusion:  Solves the problem by unhooking the oxygen sensor and modding a
lean fuel map for proper running.   This uses a little more fuel and increases
emissions slightly, but it works.

Power Commander:  Close to the same approach.  A little more control over
things.  You can increase performance if you're willing to sacrifice a little
economy.

Dual Plugs:   Burns all the fuel in the cylinder so the oxygen sensor doesn't
trigger the problem in the first place.  This is the best solution because it
burns all the fuel, increasing economy and gives you a little boost in
performance as well because you're burning a bigger effective charge in the
cylinder each time.

If you really wanted to break the bank, you could get dual plugs AND a Power
Commander, then juice the standard fuel curve up with the aid of a dyno to
burn more fuel efficiently.  Dual plugging should allow the bike to run a
richer mixture without have so much unburned fuel.  Might give a little more
peak power and would definitely make the torque curve feel fatter, which is
where it's at anyway for a street bike.  Emissions and economy might be
affected somewhat, but the bike would run a lot cleaner than a single plug
bike and the potential performance improvement would be more because of the
full burn of dual plugs.   A lot of big displacement twins can benefit from
dual plugging.  Aprilia uses it in their RSV, Falco and Futura 998 cc balance
shafted V-twins and it works great.
