You'll hear some pretty nasty opinions about Cobra pipes (which they've
discontinued due to too many warranty claims I heard). Based on what
I've seen of Cobra pipes on KLRs, sell the Cobra on Ebay immediately,
and use the money for something useful, like Progressive fork springs, a
different spring for the shock, or improving the brakes.

Do you mean the idler shaft lever, AKA doohickey? The 88's had a
different design, one that was apparently less prone to outright failure
and more likely to just have the chain run a bit loose.

Three hp maybe. You'll get a noticeable improvement in throttle response
when you drill out the slide and fit the different needle. This is 95%
of the improvement right there without chainging the air filter or the
exhaust pipe. As for the pipe, don't we all have enough trouble with
riding areas being shut down? I just put the stock pipe back on my '01,
and had one of the best offroad riding days in a long time. The stock
pipe gives the most controllable, smooth, driveable power. Which is what
you need for trail riding, or flattracking turns in the city.
You can open up the airbox a little bit, which seems to make some
difference at small throttle openings. I was using an O2 meter, and when
I drilled 4x 1" holes in the airbox it made a LARGE change in the
mixture around 1/4 throttle. No change on top though.
If you open up the airbox, your fuel mileage might only go down 10%.
