    light weight ppl big bikes

    Here's a perfect example of throttle and clutch control: A while back in the Moto de Nations Ryan Villapoto was able to holeshot the entire line of the best riders in the world....both the MX1 and MX2 were on the line (250f and 450f). This is with Ryan on a 250f against factory 450's! As you can see having lots more horsepower doesn't equate to winning starts if you can't get it hooked to the ground. Remember too that Ricky Carmichael would almost always get the Holeshot and he was by far the smallest and lightest guy on the line! He always stressed that he never whacked the throttle or dropped the clutch...if you look at race photos he always has his middle finger on the clutch ready to control wheelspin whenever the the motor exceeds the capability of the tire! As others have already pointed out THIS is what you need to master, and the more you put into it the quicker you'll become. BTW all of these techniques directly transfer over to offroad riding and racing! ENJOY the journey!!!!!

    wont go through water-230

    I had the same thing happen to me, after isolating the problem it turned out to be water running down the spark plug wire and into the junction of the plug boot. Team Old School solved the problem by sliding a small rubber/silicone boot down over the junction. This prevents any water from getting in and Viola! she handles all the water I can throw at her(feet are lifting off the pegs at times). Definitely worth a try.

    How to preload suspension?

    JP, A basic overview, pre-loading the suspension is simply compressing the springs before/at/during the moment you hit an obstacle or jump, which transfers more energy into the springs and causes them to rebound with more force which translates to the bike leaping up higher....good for clearing tough obstacles or getting a little more distance. Usually we use the riders body weight/energy, but you can also use a small tree, rock or bump to pre-compress the suspension(think Trials guys using a baby rock to get them up and over a large boulder). Normally we ride using our legs/body as extensions of our suspension so by sucking up our weight before an obstacle the bike only sees its weight and not the riders, this is exactly opposite of preloading. Two most common ways to pre-load, 1. pretend your trying to jump off the bike by pushing down with all your strength through the pegs and bars. 2. Sit down towards the mid/rear of the seat as your riding up the face of a jump. Both ways pre-compress the springs and transfer the bikes energy and the riders energy into an equal opposite reaction resulting in a bigger leap. You can see that by pushing down on the bars,pegs or rear seat you can bias which end is preloaded more which will change the launch characteristics. Obviously to keep this from being a novel, this is a simple overview. I would suggest you watch a You tube video of David Knight play riding over lots of obstacles, along with Trials guys going over huge things, notice how it's a timing thing and watch their body positions. Also go out and practice on a small object yourself, along with seat bouncing a small jump... just be sure to go slow and take baby steps to minimize the dirt naps. Hope this helps, Jeff

    fuel range

    We've kept track of the Old School racer and it varies between 27-45 mpg. Fast flowing trails get the highest. Things that always gobble gas are slow tech trails, mud, high altitude, dust plugged air filters,and dirt naps!. I also go through lots of gas on a MX track due to always being into the throttle and overflow from the carb from whoops and jumps. We used to ride an old washed out creek bottom that was about 16 miles round trip, it took all day and would pretty much toast 2/3rds a tank...so plan accordingly!

    Idaho City 100? Anyone?

    Did the 100 a few years back, lots of fun especially if you do both days. Very well run and seeing the factory teams is cool. BRR has four different loops they alternate each year which helps the trails to recover. It fills up fast, so go for it! Jeff

    the ride of a lifetime

    I'd be willing to show you Winom/Frazier in NE OR, it's about 1.5 hrs south of Pendleton you'd be going right by from Idaho. Also the South fork of the Walla Walla river is fun for a day too. I too like the tech. woods stuff along with a little MX & X/C. PM me when you head this way. Jeff

    XR200 & XR200R Racing / Results.......!!!

    The KDX is an excellent bike, I almost bought one before getting the 200. Anytime you can get away is good for me....June is fine. If I have a little heads-up I can tweak my schedule and go out during the week. June is great for Winom/Frasier at +5000ft and also up the Walla Walla River. On my track I made the jumps so my daughters' stock 2002 xr200r can handle all of them....I know I've done it, so your setup will do fine. We'll just air up the tires and firm up the clickers. Jeff

    XR200 & XR200R Racing / Results.......!!!

    Thanks Tom...hope you have fun with your project bike. Chuck, sorry to hear the "Little 200 that could" went to the happy hunting grounds(probably low scoring all the local enduros!). Would still like to get together and show you some fun stuff around here...maybe even get you on a track or two. What cool smoker are you doing battle with? Jeff

    XR200 & XR200R Racing / Results.......!!!

    Missed the racing stories, so thought I’d bring this back. Last Sunday the Bike Pit of Pilot Rock, OR hosted its’ first MX race as part of the WRA Racing Spring Series, since it’s only an hour away, Team Old School couldn’t resist. This track is a long outdoor full-on MX, with lots of big doubles and tabletops. I’ve ridden it before, but was frustrated that the little 200 couldn’t clear the biggest jumps. Fortunately for the race, the track was smoothed and widened, and the jump take-offs were elevated. I managed to talk my old race buddy Mark into joining me, and we both entered the +50 class. Mark rides a ’04 Suzuki 250f, and although everyone else would be on 450’s, we planned to put up a fight! Old School Al was a little unsure at first, but after practice we were both grinning! I was able to clear all the big jumps and was even able to pull away from a few riders. Well it was time for the first moto and we had about 12 guys on the line,( a mix of Vets, +40, +50) the start was soft and long and I knew that would be a problem for the 200. Sure enough, I got a good jump off the line but was quickly 2nd to last into the first corner. Somehow Mark had a “Villapoto moment” and holeshot the entire group, rounding the second turn in the lead, his bike coughed and died which was just what the 200 needed, I think I was 4thout of the first turn and 2nd out of the second turn due to Marks’ mishap. Needless to say I was running like a scared rabbit with wolves close behind, I wasn’t sure if I could hold off the faster bikes for five long laps. I snuck one quick look back and saw a Yamaha 450 about 5 seconds back , this prompted me to turn it up one more notch. Coming out of the back stretch toward the spectator area, I’m not sure who was more surprised to see the 200 in 2nd place, me or the crowd! I wound up finishing 2nd overall and 1st in my class, 6 sec. behind the leader and 5 sec. ahead of the Yamaha. The start of the second moto was cold and very windy, I lined up next to Mark hoping his holeshot Mojo would somehow inspire the 200 to forget it was a 200, once again I got a nice view of everyone’s rear fender, but luckily followed Mark around traffic and left the second turn in 3rd place. Mark and I quickly passed the same guy on the Yamaha 450 but he out horsepowered me down the next straight, you could tell he wasn’t going to let an XR200 beat him twice! I fought to stay within striking distance and did pass him in several corners around the track, only to have him pass me back on the straights...I really needed that 5 sec. cushion I had on the first moto. We caught up to Mark who was easing up slightly but since we were all running the same lap times, the order didn’t change. Coming off the big spectator jump, I almost took a dirt nap when a big gust blew my wheels out from under me, it knocked my foot off the peg, but somehow I stayed up. We finished the moto 1-2-3 like a freight train and I was happy all went well. According to Mark we were all tied with 4 points each (his 3,1) (my 1,3) and the Yamaha 2,2 since the second moto is the tie breaker , Mark was 1st, Yamaha guy 2nd and myself 3rd. Afterwards we had several guys come up and comment on how well the 200 did, especially the guy on the kx500 who still couldn’t believe we had beat him both motos! It was a great day at the races and lots of fun, Team Old School can now add a modern MX race to our portfolio! Old School Jeff

    Tom, thought I'd jump in, here's some random thoughts: I'm 155 lbs and pretty aggressive on the 218, also I ride Woods and MX tracks with good sized jumps so I've always been looking for more bottoming resistance front and back. Since your 180 lbs and your woods only, you might like my setup,although you'll need more preload front and rear. The Emulator shim mod is great for more damping when taking big hits and jumping, I doubt that you'll need it in X/C woods. It is simply a mod that uses 3 thin shims that flex open for oil bypass instead of using the brass poppet valve held down with the little spring. Doug the susp. tuner had played with this before and knew where to start...he hit it very close on the first try. I went from 7-10wt oil with stock emulator to 15wt with shim mod(which also slowed the rebound damping). The forks are slightly harsher on small stuff but feel 25% better on bottoming resistance. We modified my Works shock by shortening the topout cup, which extended the shock an 1/8" to 13 5/8" eye to eye. This gives me about 11" travel, along with raising the bike up for logs and deep ruts. It might be possible with the Honda shock as well. With the stock Emulators I was looking for a heavier small spring for two reasons, 1.) I didn't like the 4 turns of preload, it made the forks harsh on little stuff. 2.) When the valve opened it went all at once and still wasn't enough bottoming resistance, (so just like a rear shock spring I needed a higher rate spring with less preload). In the forks I run 2psi air for woods and 5psi for mx tracks, really I need higher rate fork springs but this works for now. At 180# you'll want some air in them too. I would start by not trimming the Progressive springs with the emulators since you will need more preload than me....always check your rider sag and the bike-only sag to see if you're close on spring rates, I think you'll need a heavier shock spring off an 84-85 xr250 (Chuck can help with this). My 218 is running about 25% front and 28-30% rear sag and has 1" of bike sag. It follows the ground extremely well and is killer in mud and ice. Due to the high leverage and linear rate of the 200R linkage/shock placement it requires a very high rate spring, I'm running a Works 600#/in and wish it were a 650 or a 700. (Ideally a progressive rear spring would better mimic a modern rising rate.) All this energy is very taxing on the damping requirements...I'm running the stiffest ball springs Works has and wish I had higher rates still! Probably need to run slightly smaller holes in the Works piston on the last stage of comp. damping. Really all this boils down to how your using the bike, your speed/skill level, along with what feels right for your riding style. On a project like this, ask lots of questions and watch out for well meaning misinformation! Jeff

    18in. vs. 19in. rear wheel debate

    I have a 218 motor in my 200 and I've ridden various bikes and tire combos. I ride 50/50 Woods and MX. I have a buddy who put an xr250 motor in a crf450 chassis who rides with me a lot, and he stayed with the 19". Yogi prefers the trials tire since he rides very tech. and slippery PNW woods and he doesn't ride mx, it is superior in these conditions. I did notice my 200 climbed better and was nicer in the woods with a taller-profile/wider rear tire (110/100-17). With a H.D. tube it allows me to run 8-10psi and it works well in slick conditions. The trade off is it's heavy and doesn't spin up as fast (mimics a larger flywheel). It really depends on your type of riding....for you it sounds like a knobby for the most versatility. If you’re an expert in the woods and you tend to hit rocks/logs at full speed, then you’d like the taller 18” tire with HD tubes. It will protect your wheel better while running lower pressures. You could also run a 19”low profile with foam inserts like a lot of the pros run…but this isn’t practical for most weekend warriors. I think I would steer you towards the 19” with a med. HD tube, it should get you through the woods at lower pressures, and it will work well on the faster mx/harescramble stuff. The advantages would be lower rotational mass and unsprung weight. Since you already have the 19” you can spend the extra money on getting the suspension tuned for your weight and riding conditions (a better bang for your buck!). If you start tearing up rims and flatting, then go to the 18”. My friend with the XR/450 conv. likes the 19” and we haven’t had any problems with flats or bent rims to date. He also rides 50/50 woods and MX and is a “B rider”. As far as sprockets go there are plenty to choose from, start with 12/47 or 13/50-51. Hope this helps….. Old School Jeff
  13. Had an epic day of riding yesterday, blue skies, 50 deg. temps, perfect conditions. Was able to get to the airplane wreck, 2/3 up Burnt Cabin and 3/4 up the river trail. Still a fair amount of snow and you had to be on your toes on the ravine crossings as the snow was drifted in and sloped the same as the hill....you just had to have faith there was a trail 6" down. There was a fair amount of blow down and we had to huck over six trees and go around that many more, even so managed 27 miles in about 4 hours, as ususal the little XR 200 came through like a champ. Invited a 28 year old on a KTM 125 that was totally trashed by the end of it all.....I know that wasn't exactly fair on my part but "old age and treachery..." Wish I could have gotten some pic's, but will do a better job next time. Boy it sure felt good to be back in the woods again! Jeff

    XR 100 Choke Question

    Socal is correct, typically you only kick over once or twice with full choke on a cold or balky motor, then switch to half choke and it should fire right up. Our small honda's chokes won't raise the idle speed when applied, and will not idle with full choke. My XR200 cold starting drill: Raise idle speed by turning in idle-speed screw 1/2 turn, 1-2 kicks full choke then set to half-choke,full kick and motor starts right up and fast idles, after a minute or two choke off, and lower idle screw back to normal as motor warms up. My XR100 likes this same technique also. Hope this helps.
