Welcome to WMTA. First thing to learn from the video is to always (ALWAYS) keep your finger on the clutch. DFW

Sounds like the front wheel bearings may be trash. The front disc is attached with half thimbles which are secured to the hub with socket head screws. These screws can come loose. If they do come loose they will eventually stick out far enough to contact something and the the fromt wheel will stop instantly. Cheers DFW

It was $1.499 a gal in Casper WY today. DFW And the answer to the question is: not in a long while.

Just remember, "There is no replacement for displacement" Cheers DFW

Neonsurge, This is the 3rd Party that I belong to. Libertarian Party

AtomAnt Wouldn't happen to be an Ayn Rand Objectivist would you? If not I suggest you read "Introduction to Objectivist Epistemology" and "Atlas Shrugged" Cheers DFW PS Everyone should read: "Return of the Primitive: The Anti-Industrial Revolution", "Capitalism: The Unknown Ideal", and "The Virtue of Selfishness: A New Concept of Egoism"

Judson, I moved to Casper from Pampa, TX in May of this year. I got to ride most of the WMTA events. WMTA is a great group. We had lots of riders from Colorado come up to several of our events. We really enjoy the folks from Colorado. So haul up your tent or drag up your trailer and come join us. We will all have a great time. Doug Wilson WMTA

I bought a 250 Alpina in 1970. I had two chains and two rear sprockets. The stock (as I remember ) sprocket was 36 tooth and I purchased a 48 tooth to ride in the hills. This worked pretty well. Cheers DFW

Are you sure that it wasn't Carne Adovada hanging in a Pinon tree?

I have an 03. I like it. If you get one you should get the new wider/deeper front disc and pads. These make the front brakes more progressive and less likely to throw you over the bars. A rear carbon fiber exhaust silencer guard is a good idea. Since it is an 03 the middle exhaust has probably blown out and been re-welded already. The new flat bash plate is a worthwhile. The clutch adjustment can be a little tricky as was designed for a cable linkage and Scorpa has adapted a slave cylinder to operate the clutch lever arm. All in all a good bike. Cheers DFW

KevinE, I have an 03 SY250R. The SY250 has a hydraulic clutch. There is a slave cylinder that actuates the clutch lever. There have been problems with the linkage. Once you get it set up properly it will work fine. It has a KTM style non-linkage shock. The plug is not easy to get to. Removing the carb requires removing the airbox. My exhaust center section has split and had to be re-welded. If you get one make sure to get a carbon-fiber silencer guard. The head angle is very steep. It has a tendency to tuck under and pitch you over the bars. It is not as easy to learn on as say a Montesa Cota 315R. The newer bikes have a bigger front disc and this makes the braking more progressive. The touchy front brake and steep head angle on my 03 may have helped me get the nickname OTB Wilson. All in all it is a good bike. Ciao DFW

dad, Looks like a lot of fun. Too bad it dosen't have gears and a clutch. I wonder how much it will cost? It reminds me of a Yamaha Trickster or a Scorpa for tricks. Cheers DFW

Cope, I went on a job interview in Bay Minette which is just across Moblie Bay a few years back. I was lucky enough to tour the ship when they were having a reunion. My wife and I tagged along with 5 guys who served on her during the war. It was an amazing time. I marveled at the bearings holding up the gun turrets. I don't think that there is a machine shop in the US now days with a mill that could machine the races. DFW

Ya'll best not be talkin about nailing my sister! Ah thats right ya'll said roll out, not roll over.

Darrell, Perhaps not as much mud as at Centerville a few years back but still plenty of mud. During summer time in Wyoming it is so dry that you have to prime yourself to spit. I guess that is why we are so excited to see some mud. We rode the first two loops of our last trials at Limestone Mountain in the rain. By the end of the third loop it was dusty again. All the rain did was wash the dust off of the rocks and make the logs slick. Ciao Doug

Who all are coming to the Ahrma Mosteller Cup? It should be great fun. I have been helping Fred, Dan, and Bob set sections. There will be a wide variety of terrain. Everything from creeks, mud, logs, mud, (oh did I already mention mud), mud, rocks, roots, mud, slick grass, mud, concrete, mud, and/or a combination will be in each section. Look forward to seeing you all there Doug Wilson

Edouard, Both my parents are retired petroleum geologists. I think that this is the reason I am a petroleum engineer. They found it and I had to figure out how to recover it. My son-in-law is a chemical engineer for Total. Welcome to the trials family. From the video it looks like you are having fun. DFW

Vaughan, I think that just recently there was a long winded discussion on this very subject. Take a look at the picture that I attached. This is how the slave cylinder should look before you pull in the clutch lever. If there is more room than shown between the lever and the end of the cylinder the clutch is out of adjustment and you will never be able to bleed or adjust it. To bleed the slave cylinder you must remove the tank, carb, airbox, and top bolt on the on shock. Remove the bolt from the slave cylinder and thread slave cylinder and hose past the rear brake reservoir. Clip the ny-tie and hold the slave cylinder up next to the master cylinder. It is a good idea to mark the orientation of the hose fitting in relation to the slave cylinder. Unscrew the hose from the slave cylinder and and tie off the hose to the brake lever at the same level as the clutch master cylinder. Hold the slave cylinder so that the hole is pointing up and fill it with brake fluid. Push the plunger into the slave cylinder and re-fill until all of the bubbles are gone. Pump some clutch fluid through the hose and then screw the hose onto the slave cylinder. At this point the slave cylinder will have excess fluid in it. Thread the slave cylinder back down to it's original position and bolt it in place. While adjusting the slave cylinder into place you will have to compress the slave cylinder. This will force the excess fluid up the hose and into the reservoir bleeding the cylinder. When you actuate the clutch lever with the reservoir lid and gasket out make sure that the piston makes a full stroke so that is will bleed out any trapped air. If it is running in the right part of its stroke you will not have a problem with the clutch. Most problems with a Scorpa clutch stem from the slave cylinder running too far out in its stroke. When this happens the clutch lever will not be able to be pulled back to the handle bar. When the clutch lever is pulled too far (if adjusted properly this should not happen) the slave cylinder piston will bottom against the cir-clip and force fluid to leak around the fitting or break the slave cylinder (this option costs about $70). No amount of tightening will stop this leak. I fixed the bottoming out problem with my Scorpa wit a suggestion made by Ryan Young. He said to place the lock nut on the other side of the lever not like it is shown in the picture. This solved the problem with my bike and had I done it first I would have save the money for the new slave cylinder. Hope this helps.

I think that the Dabster is right. Yamaha is not too interested in this engine. Just look at the grand investment Yamaha has made to adapt the engine to use a hydraulic clutch!!!! Scorpa may well have to drill and tap the hole themselves. Cheers DFW

gi125, Sign up for a Yoga class. The scenery is great (at least in the classes I have taken) and they will teach you how to stretch properly. I went to a physical therapist who practices the Feldenkries method and she had me buy a OPTP 6 x 36 black hard foam roller. You lie on the roller with it aligned along your spine. It relaxes your back. You can then raise your head and the effect is like going to the Chiropractor. It will pop all of your vertebrae back in line. Hope this helps. DFW

All, I looked up the Nelson model 49022 spark arrestor and it is rated for an 18 hp and smaller 4-cycle engine with a flow rate of 89 cfm. Ciao DFW

Ringo I am running Motul 800 full synthetic at 80:1 in both the 99 Sherco and my 03 Scorpa SY-250R. Ciao Doug

I have both types one I bougth from Lewisport and one from RYPUSA and have used both on my son's 99 Sherco. The larger one stays cleaner much longer because the carbon collects in the mouth of the bell instead of impinging directly on the screen and clogging it up. You can only carry so many cans of carb cleaner in your back pack. Stopping every several hundred yards along the trail to clean the spark arrestor is not fun. DFW

John, I just had the my 03 all apart and measured everything. Nothing was out of spec. The only thing not easy to measure is the angle at which the lever is welded to the shaft. The easy fix is to move the lock nut to the inside of the adjusting screw and adjust the adjusting screw so that it is flush or there abouts. This allows the slave cylinder to operate in the proper range. I think on my bike the top bracket was welded on at the wrong angle. Both Mike Komer and Ryan Young help me with the problem. Try this before you take the clutch apart or replace the slave cylinder. I did both to no avail. DFW

Don't buy the one from Lewisport unless you have a 4T. They clog up way too fast on a two stroke. I know this from personal experience. Ciao DFW
