    Just returned from Odessa, Washington and the Desert 100. Had a great weekend, fantastic riding, great friends, everything you could hope for. :D

    Report here; http://advrider.com/forums/showpost.php?p=21141413&postcount=294

    As reported previously, the fork oil had been changed out for Honda #10 weight fork oil, 500 cc per leg, or approx 135 mm oil height. A few shorter trail rides indicated improvement, most notably the choppiness on pit run (gravel or road bed-rock approx 4" diameter) was gone. Experimenting, I also cranked down the rear shock compression damping to within 5 clicks of full and rode some more. Me like! :D Then my buddy Luke rode it and said he thought the back end was kicking on rebound and should be ajusted for that. We talked it over and decided to wait until we were out in the desert and could adjust and check on the fly. We turned the rebound adjuster (at bottom of shock, just above link) in and out just to see where it was at and we were within 6 clicks of full rebound.

    Got out to the desert and during Saturday's poker run, stopped at the first check and screwed the rebound in to within 2 clicks of full. Now we are getting somewhere! She is no longer kicking like a mule coming out of the whoops, much more stable and forgiving.

    The next day, rode the D100 (I'm a super senior so only had to ride one 50 mile loop, but trust me, this course is very tough). She behaved very well, I'm thinking the bike is as good or close to as good as I can get until rebuilding the suspension with gold valves front and rear. We have not pulled the front fork plugs (yet) and are assuming that they are at the factory setting of 11 clicks (out of 22) and they do seem fine now after the oil change. Will pull and check these just to be sure.

    Hope this helps the rest of you with your setups and by the way, the steering dampner saved me several times, most notably when coming thru a fenced/gated section in second gear, hit a hidden baby head that started to launch me into the fence post and the bike just righted itself, close but no crash. Awesome!

    Here is one action shot from Sunday's race, very close to the finish line;

    Happy trails! :clap

    As the title said, I bought a new TT-R250 last week, wanted a lighter electric start air cooled bike.
    Fitted Acerbis Rally hand guards
    B&B bash plate
    Enduro mirrors
    Staintune muffler
    Moved the forks up in the triples
    wound back the rear spring preload

    Some photos:

    Can anyone clarify the front fork adjustment on the TTR225? I see the rear has both pre-load and damping. The fork just seems to have damping adjustment.

    Is the pre-load adjustment on the forks basically a spring change?

    The rebound damping adjustment knob on the bottom of the shock on my 2005 TTR250 doesn't "click" when rotated. The manual describes settings in terms of "clicks".

    As it is, I have been making adjustments based on the number of partial rotations of the knob.

    Does anyone know how the clicker mechanism works and whether it is in any way required for the proper adjustment? I'm trying to determine if a replaceable part is missing.

    My guess is the clicker mechanism serves to hold the adjustment knob at the desired setting, but is independent of the shock vertical function.

    Below you can kind of see the aluminum heat shield that goes between the pannier bag and the exhaust. It also goes between the side cover and the exhaust as well. This has been an awesome addition, allowing me to keep the bags further back so I can use more of the seat. Im 6'2" and I need to be able to scoot back on the seat every once in a while.

    The cutting board skid plate did excellent. I did some higher speed riding since I was alone (Read: not fast and out of control, it just wasnt as leisurley as normal) and it took some fist sized rocks being thrown at it pretty damn hard and it shows no signs of damage. Im quite happy with this.

    And the ex-CBR windscreen. There is a gap b/w the screen and the "fairing" that air moves through and I think this creates some slight turbulence around my helmet...I will have to plug this gap somehow.

    Swamper,

    I have searched the intereweb extensivley for this info and found very little, just enough to tell that the adjuster screws at bottom of fork legs (under rubber covers) should be the adjusment for compression. I recently popped the rubber covers off and found these were at 10 turns "out", from what little info I've found, the more clicks "out" reduces compression dampning. Interestingly, there was a tiny "10" stamped into the adjuster, under the rubber cover. Since my TTR250 has a tendency to pitch forward on downhill jumps, I've adjusted it to 7 clicks "out" and will report results when I've had a chance to try it out. :D

    I had been wondering why I haven't seen more on the TTR around the forums. They seem like they would make a great DS, and the price is so much lower than a lot of the other bikes it's size on the market. Personally, I like the simplicity of an air-cooled engine, and I don't need a ton of power cause my skill level isn't up there (for now anyway) in that realm.
    Glad to come across this tread

    The TTR250 is a bit of a forgotten bike... they are quite trick
    for what they are... fully adjustable shock - pre-load/rebound damping
    & compression damping adjustment .. forks with air pre-load & rebound
    adjustment in the bottom.. & they are not overly heavy at 130kgs..
    I have a GYTR tail pipe & short header pipe.. made the motor come alive
    lots more bottom & mid range..the WR250f Rekluse clutch is just magic in real tight terrain...

    the next mod is a set of 05 YZF USD forks...

    Nearly 100% of the TTR250s sold in the U.S. were not set up to be street legal. They are essentially the same bikes as sold in other markets in street legal form (ex. TT250R, etc.)

    The 2005 I have (in the U.S.) even has the threaded sockets for the rear-view mirrors in the factory handlebar fittings just covered up with a plastic plug.

    If you search the for sale listings in the U.S. you will find quite a few TTR250s which have been converted and are currently titled and registered for street use. So, if you are thinking about the bike as a DS, you can probably find one reasonably priced which is already good to go.

    Mounted up my Garmin to use as a speedo / odo / GPS. Much better than the odometer-only setup.
