: I have a 98 KLR 250 and it is hard to find
: stuff. I don't think there's much you can do
: with the stock parts. I added a Cobra
: exhaust; it's DOT & USFS approved. I
: added a TwinAir filter (K&N doesn't make one
: for it anymore). You can also get UNI filter
: plugs. A set of 6 plugs will cost about $10.
: You should be able to find room to drill 4 -
: 1 inch holes in the air box BEFORE the air
: filter and install the filter plugs in the
: holes for more flow. Notice I said BEFORE the
: air filter. Even though these filter plugs
: have a small foam element, if you install
: them AFTER the filter, they can let enough
: dirt in to damage your cylinder bore. I found
: out the HARD way. If you do this and rejet
: it, you will notice a difference. With no
: wind to speed me up or slow me down, mine
: will usually top out at 85 mph at 8500 rpm,
: with about 1000 rpm to spare. I found a 1
: tooth smaller front sprocket (couldn't find a
: bigger rear), and now it does 85 at about
: 9000 rpm - no loss of top speed and a slight
: gain in acceration. I found information about
: a cam from a company called Megacycle. I
: haven't looked into buying one yet. NOTE:
: with the mods I did, it will continue to make
: power above the 9500 rpm redline. HOWEVER, if
: you let it go above redline far enough and
: often enough, you can wear down the cam and
: rocker arms. I found out about that the hard
: way too. I also found out about an IMS
: plastic tank that increases fuel capacity
: from 2.9 to 3.2 gallons -not much increase,
: but it should be lighter, and lower the
: center of gravity because you're reducing
: weight up high. I ordered a Works shock and
: spring through Pro Action and had them re-
: work the forks. The suspension is much
: improved, but it still is no motorcross bike.
: I ride mine in the Ocala National Forest here
: in Florida, and due to the sand I bought
: Dunlop D606 tires. They look just like normal
: dirt bike tires, but are DOT approved and
: should last longer than the factory tires.
: After I wore them out, I installed Pirelli
: MT21 tires. They do about as well off road,
: but wear quicker. Get the Dunlops. There will
: be a small amount of noise and vibration
: increase, mostly at low speed, but the Cobra
: exhaust and engine vibration masks the tires
: at high speed. By the way: one time I was on
: Interstate 4 going down a slight hill and
: with a good tailwind, and with full throttle
: was showing 100mph on the speedometer!
