    Been doing a lot of DS riding lately, so the 525 has been getting all of the love. My 300 is plated, but that's really just for riding short pavement shots and fire roads to connect trails. I finally had the chance to take the 300 out for a spin today in the mountains. Within the first 5 minutes on the bike, I remember why I like riding 2 strokes so much, and specifically the 300. It's such a blast to ride. :clap

    Here are a few pics of my 2000 300EXC.

    As bought a few weeks ago:

    I finally got up in the hills with it and absolutely love it!

    Like a 50hp BMX bike.

    I'd be curious to see a before and after dyno run with the carb mods. I'm not familiar with their intelijet but the keyhole bore is a common mod discussed on KTMTalk, it's supposed to work very well. 36mm carb bore off idle and 38/39mm bore at larger RPMs, sounds like that extra jet provides additional air/fuel at higher RPMs.

    Since I can't outride the motor on the 300 :cry I'd probably go the smart carb route, twist of a knob to adjust the jetting :clap

    BS. We ALWAYS need more power!! :lol3

    Oh yeah, and 6 gears. :baldy

    I may try the Dick's Racing mod later. Right now, I just need to ride the damned thing!!

    Wow! That look's like 0-12 points in 6.7 seconds!


    Tick-tock.........

    I put some fresh paint on my aux number plate tank and mounted the aux halogen light on my 300 (slightly better than the KTM glow-stick)

    RFs pic looks like where i'll be in two weeks:deal

    On the subject of better lights, i ordered a cheap HID 35w to try in my 08 oem housing. Will it stay lit for a while if i run a dedicated circuit back to my battery? I'm running a TurnTech battery.

    I know that it will only work on DC but i think the kokusan 2k3 is what I have? which should have at least 35 watts on the DC side. Not sure if floating the ground is possible or needed. Can't search ktmtalk since its down...

    Also, will it melt the plastic housing?

    I wouldn't run the HID on the stock/non-mod stator system. Battery will go dead and the HID will not work with voltage below 10-11 volts DC. Then you will have no lights (unless you leave the lil 194 park lamp bulb in running off AC)

    And once you discharge the Lithium Ion batteries (because the HID light sucks more juice than the stator can produce) your nice Turn Tech battery will be compromised.

    I got one of those 65W PMX H7 halogen kits that includes the bulb and holder to fit an 08 OE headlight. according to PMX: No stator mods required for all 4 strokes and 2 strokes with 2-k3 or Kokusan stators.

    It's def much brighter, actually usable. I rarely turn it on except if I get caught out at night so I'm not too worried about the battery. When I have used it the elec start doesn't seem to mind :D The lifespan of the stock bulb has only been about 2 or 3 months for me.

    Here's an LED option also.

    I love the functional aspect of your bike Jeff. Info on tank and light? What kind of stator setup are you running? BTW, daughter says I can store a bike in her garage in Littleton so I may be riding my 300 more in your neck of the woods. :D

    If you have a XCW then the head lamp is powered off the AC circuit. The lighting circuit is AC and is around 85 watts and the battery is run on a 25-35 watt DC circuit. So your battery won't get drained. But if you add a HID light to the DC/battery circuit the stator will not be able to keep up with the current draw.

    Stock stator. Light is a halogen H3 that I picked up 15 years ago. It's superior to the stock KTM light, but not by much. I have a second light I will try to mount just to see of the stator can power it.

    I'm running HID + LED on my 450, but it is much more likely to see night use. I'm hesitant to convert the 300 to full DC.

    The front tank is an older Acerbis number plate tank. The older ones have a petcock on the bottom. The newer ones seem to rely on a siphon.

    FYI, I've also installed a cooling fan on my 300 with an override switch (manually turn on the fan). It got a lot of use when we rode Star Trail in Taylor Park this weekend (both directions).

    Give a shout if you want to ride. I don't pay much attention to the Colorado/Texas thing. Hell, I've even ridden with TNC and found him to have reasonable social skills. :rofl

    I was a bit disappointed, I didn't get to see the anti Zombie machete in action.

    As we sat on top of Taylor Pass, another rider came along with the identical saw. We basked in mutual admiration of our prowess. With that said, all of the down trees we encountered this weekend would have required too much effort to cut by hand and had workable ride arounds.

    I think I need to ck my X dim, it looked ok when I assembled the topend, slightly proud. I think the new gaskets might have squished down a little putting it toward a bit too much compression. The fan ran allot this weekend and it usually never comes on.

    The trails were so easy I can't imaging it running hot.
