    The service manual calls for "ethylene glycolbased antifreeze designed for aluminum radiators mixed with distilled water. The percentage of antifreeze should be between 50 to 60%." You don't have to run special coolants.

    SoCal Thumpertalk Ride April 19-20

    I had a great time riding with some new friends. It was a pleasure to share some of the great trails at Gorman. Carpedrz led a morning and afternoon loop on the best stuff there is down in the valley. I rode sweeper and I believe we returned with all the riders we left with. I could only ride Saturday but managed to log 70 mi. on the odometer. Here are some highlights. There is our trail boss Carpedrz (Jake) on the left. Great job Jake! Well, I think we should go this way. Single Track? Looks like Interstate 5 to me! Here's Jake teaching an impromptu class called "Flower Roosting 101" If anyone would like the hi-res originals of these for prints, give me a PM. Joe-R

    SoCal Thumpertalk Ride April 19-20

    Hello, my name is Joe R. and I am a Thumpertalker Hungry Valley is my main riding area so I thought I'd say Hi. I will come up Saturday for some riding. My buddy CARPEDRZ (or should I say CARPEYZF) knows some great unmarked single track in the valley. I have ridden up in the forest several times since it opened up this year. The first time I got stuck in 3' deep ice banks up on top of the mountain. The forest service went in with a small dozer and leveled off several miles of the whoops on Tejon Trail. A little snow and rain to settle the loose stuff down should make it nice. They left the rocks though. As for the weather, here is one of my favorite links when I'm pondering what the weather is like up at Hungry Valley. Frazier Mountain Weather This site is basically on the North side of the mountain, and Hungry Valley is on the South Side. You can get a good idea of the snow level, temp, and don't miss the webcams. See You Saturday

    Dynojet fine tuning

    Ok, I will try the stock (22.5) pilot jet for my next ride. I am a little nervous about working on the carb out on the trail as the little dropped parts get harder to find as I get farther from the truck. (Maybe I should use that emergency space blanket in my pack for a drop cloth.) My intention is to try for a setup that works good at 3500', will get me up the mountains ok, but won't be too lean for an occasional ride at sea level. My idea of a great compromise is having a nice trail bike that will take me anywhere I dare to try up in the mountains on the weekend, and then on Monday I hop on and putt to work. The amazing thing is how much the fun factor is increased by the dynojet mod waking up the bike's performance. Definately worth the money investment. My hat's off to Burned for providing us with the benefit of his research and leg work on the set up. Joe

    Dynojet fine tuning

    I just installed a Dynojet needle and spring in my 400S. I had run the 150MJ/27.5PJ setup with no real problems for the last 2 years. I live at sea level but my riding area ranges from 3500' up to 8500'. After exhaustive lurking in the jetting database, (and studying Eddie's every word ), I started with this DJ setup: MODEL: S MAIN JET: 134 PILOT JET: 25 FUEL SCREW: 3 turns (Keintech extended) NEEDLE: dynojet 4th AIR BOX: 3x3 hole PIPE: Stock w/end cap drilled ALTITUDE:3500 AND UP COMMENTS: At my staging area (3500') the bike runs awsome. It will launch the front end easily in the mid range, and has much better off idle grunt in the low gears. I climbed some familiar hills and found I did not need to carry as much speed going in to keep in the power band. I headed up into the forest. As I got up higher on the mountain it developed a severe blubber coming off idle that got worse with increasing altitude. Once the RPMs came up a bit it still had good snap and revved like crazy. I cranked the fuel screw IN thinking it was rich on the low end. This helped a little and improved the idle at this altitude (aprox 6-7K ft), but it got too scary trying to climb the goat trails with no low end response so I headed back down. Back at the truck I found the fuel screw was now 1 1/2 turns out. The main jet is probably too rich for this altitude but can it affect the low end this much? Where should I go from here? Thanks - Joe
  6. My buddy Scott just bought a 2001 XR650R from a desert racer friend of his to replace his old 86 XR600. As this is our Flex Friday off work we figured we would go to Gorman and do some riding and avoid the weekend crowds. After a quick cruise down BackBone Trail we headed up Sterling Canyon to see if the upper forest trails into the Los Padres National Forest were open yet. Surprise, the trail was open. We headed up Tejon Trail, and in the sandy damp places we saw no tracks. There were lots of rocks, lots of ruts, lots of stutter bumps, and lots of tree limbs littering the trail. Life is good. At the Junction of Arrasta trail we stopped for a short rest and a single rider passed us and headed on up Tejon. I think he was a forest service guy checking the trail. We made a right on Whata Trail and headed on up Frasier Mountain. There were lots of rocks, lots of ruts, lots of stutter bumps, and lots of tree limbs littering the trail. Life is good. Once on top of Frasier Mountain at 8000 feet we headed over past the lookout tower intending to descend East Frasier back down into the valley. But as we made our way on up the fire roads gaining more elevation the snow banks kept getting deeper and deeper and wider and wider. Funny thing was they were like snow cone ice instead of snow. I was having a harder and harder time getting across the ice banks, and I made a mental note to replace my almost smooth 756 knobby before I tried this again. Finally I managed to bury my DRZ up to the skid plate about 100 yards into this slushy 3 foot deep ice patch. I pushed, I pulled, I cussed and all I had to show for it was a 10 foot long ditch in the middle of the glacier. My buddy Scott came back to smirk at me, and make old man cracks, (he is 20 some years younger than me). Together we got the DRZ tugged back to solid dirt. He said I was stupid for having a bald knobby. He said I was a wuss and the only way to tackle the ice drifts was with the XR600's main forte, MORE POWER. He whipped it around, yelled something about having to haul A$$, and hit the drift I had just my extricated my bike out of like he was going for the hole-shot. Well, he did make it a short distance farther than I had before his front wheel sank out of sight into the slush, followed by the rest of the bike, followed by a great over the bars handstand, heels fully extended into the sky, and a backside flat landing with a twist in the wet slush. He got up and gave me the "I'm ok sign"..... Life is very good. Scott came back and informed me it "just got worse up ahead". I agreed, so we retraced our route back down the mountain the way we had come up. I made a mental note to bring spare dry gloves if I'm going to play in the snow. I bet Scott made a mental note or two himself. We soon made it down to a warmer area. Back at the truck for lunch we had 40 miles on the odo but it felt like a lot more. I promised Scott I wouldn't tell anyone about what happened.

    Any slow guys in SoCal want to ride?

    It was indeed a good ride. After the warmup loop we did a nice loop up in the forest. We went up the entire length of Tejon Trail, then down Goldhill to Lockwood. Then we back-tracked back up and took Whata Trail to the top of Frazier Mountain. Up at 8000' the trail and fireroad had quite a bit of ice and snow. Mental note - Be careful of compression braking on the icy parts, right Ron? Then we descended East Fraiser back to the valley. With the recent rain we has zero dust, very little mud, and awsome traction. I went just as fast I as wanted to. I prefer "Riding Like a Tourist" to calling it "Slow". Going fast is a lot safer down in the valley and open areas like the sand washes where you can see oncoming traffic. It gets sorta busy at Gorman on the weekends. Astrodrz got knocked off the trail by what I would call a "really slow" guy. Steep narrow trail, trying to pass, the guy stalls right when he gets next to you, and you know which way he is going to fall. In those situations I think it's better for the "uphill" guy to do the brake and lean over to make room and then the "downhill" guy can make the pass with more control. (The fast guys would just skid past each other with their rear wheels locked up.) Some good riding was had, new friends were made, lets do it again. Joe-R

    Fork Tuning on the 'S'

    Petrie, According to my 2001S service manual, the standard fork oil capacity is 709ml (24.0 US oz). The grade is Suzuki SS-05, which is 5WT fork oil. 1. Place the fork vertically without the spring. 2. Pour the specified amount of oil into the inner tube. 3. Move the inner tube slowly several times. Hold the fork vertically, compress the inner tube fully, and adjust the fork oil level using the special tool. The Standard fork oil level is 165mm or 6.5in. (The level is measured from the top of the fork down to the oil. A turkey baster with a piece of tape 6.5in from the end makes a workable special tool.) Folks on this forum have reported good results by adding varying amounts of oil to each fork leg. (An oil level of 4.5in seems to give improved bottoming resistance.) I just dumped in 15cc in each leg, rode awhile, then dumped in 15cc more. Try clicking on the "search" option on the menu and entering "fork oil level". Your should be able to see some results other people have gotten. I tried increasing the preload, clickers, and oil level, but the real fix was to respring and revalve the forks and shock for my weight (260) and riding style (keeping up with the crazy young guys). Now they bike is plusher than stock on the small rocks and bumps but handles big hits, rocky single track, and whoops very predictably. I have not had the front end wash out since the rework. Over here we are still struggling with the metric system. So how much is a "stone"? Joe-R
  12. Hey DRZ RIK - Are you and your buddy on the S models the guys I chatted with on Frazier mountain today at the Ventura County MC Dual sport? I was riding sweep on the mountain and down E Frazier trail. It got pretty chilly up there as we did not start down until about 4 PM. I wasn't counting but about 1/3 of the 66 registered riders did the Frazier Mountain loop. According to my sources there was only one injury. It was an arm injury due to a get off in the rock garden on Tinta trail. The rider was able to ride back under his own power. Hope every one had a good ride and see you next year. How bout those Angels !!! Joe-R

    Let's try again with the link included. I weigh 260 lbs and have an 01 S. I live in Clifornia and had to stick with a bike I could dual sport. I ride 95% offroad mostly rocky single track, goat trails, and desert. The stock S suspension is way too soft and mushy for my size. The front end would wash out with no warning. The rear end would bottom reqularly. Maxing out the preloads and clickers gave me a harsh ride on the normal bumps and not much help with the front end control. I had both ends resprung and revalved through <a href="http://www.thumper-racing.net/" target="_blank">[/url] I got Eibach .45 fork and 5.7 shock springs. My priority was trail riding, not motocross (I'm 51)so I got the "offroad" valving setup. Total package $455. I'm very happy with the bike now. No more front end diving into whoops and big rocks. The ride is very plush on normal trail stuff, but I can hit 3' deep whoop sections in 3rd WFO, (when I'm trying to keep up with the kids) without going over the bars. Thumper Racing sends their suspension work out to George at </a>. He used to be with Scott's Performance but he has a shop in Tujunga, Ca.
