You might buy a nice pair of knee braces. Here is a good discussion line. Knee Braces

I needed to send my engine off for repair. I went to the local shipping stores and they wanted about $125 USD to pack and ship the engine. Too much I thought so I made a shipping crate. Bolted in the engine and wrapped it with paste board box and it cost me only $67 USD to ship it. No comments on my welding abilities please.

Well I guess you could take the radiator off instead.

Penetrating oil first. Then buy a cheap 3/8 drive impact wrench. I found one at a discount tool house for $15. Hook it up to an air pressure regulator. Set the pressure to about 2 bar or 30 psig. Slowly increase the pressure till the wrench makes good impacts. Should work. Just be careful and make sure the allen wrench is seated fully. If the hex socket on the bolt is ruined you can clean it out with a good solvent and epoxy an allen wrench into it. Make sure that the allen wrench socket adaptor sits straight and use a metal or silica filled epoxy. Once the bolt is out you can heat the epoxy with a torch to get the bolt off the socket. Good Luck.

Until 2 years ago I had a 1988 Ford F-350 one ton crewcab 4WD. It got about 16 mpg on diesel. I now have a two wheel drive Chevy 1/2 ton long bed extended cab. It gets 17-18 mpg in the city and about 23 mpg on the road. Diesel used to be priced between 2/3 and 3/4 the cost of gasoline. Now that it has to be low sulfur it costs just as much as regular unleaded. I like to drive a truck because I feel safer. Thursday on the way to work I had a Nissan change lanes into me. I had to jab the breaks and pull off the road to keep from being hit. Nearly the same thing happened on the way to work Friday. On the way home Friday a public transit bus tried it again. I would love to have something small for the commute which is 15 miles and 50 minutes each way, but I don't think it is safe in Houston traffic.

Did we plant it? No. Did we develope it and then give it to them? Yes.

Americans and Brits (Scots included in this group) found and developed most all of the oil in the world with some help from the Dutch, Norwegians, and French (logging tools by Schlumberger) so we can complain about gasoline prices all we want. We should take the oil back from bleeding idiots we gave it too and let them drive about in donkey carts and ride on the backs of camels. And such are the rantings of an ex- Petroleum Engineer

Those gorgeous red fenders break ever so easily and are ever so expensive.

What are the advantages of these bearings?

The only safe way to cut the drum is with a water jet cutter. If it had gasoline in it don't do it. If it had diesel or fuel oil you could use argon or CO2 to purge the tank. CO2 is cheap. Get a 50lb bottle and purge the drum for several days. Leave the CO2 on at a high rate while cutting. Cut only after you have pressure washed the drum with very hot soapy water. Wear safety equipment while cutting. A guy who worked for my dad tried to weld up a gasoline tank after it had been sitting out side open to the air for five years. The tank blew up and sent him through the garage door. He was in the hospital for two weeks. The welding goggles saved his eyes but his face and hands were badly burned. Hydrocarbons soak into the pours of the metal and then are released when the metal is heated. Be Careful!!!!!!!! There are few enough of us trials riders.

I don't know the names right off except I met a Father and Son at the Fall Classic that might be them? I might have a better chance to know some one in ABQ lived there from 60 to 97. Used to ride my Bultaco Alpina in the foot hills of the Sandia's.

If you are working the engine hard and the fan never comes on I think it is not a good thing.

If you are riding high up in Jemez or around Taos ie ~10,000 ft the higher octane gas may make your engine run a bit cool.

I checked it on the shaft perpendicular to the shaft between the woodruff key and the thread. Then put the flywheel back on and checked it at the edge of the flywheel parallel to the shaft. The geometry was such that the measurements are almost identical.

Mine is a 4 gpm @ 3500 psi hence the 20 feet away. Bigger in not always better. Though it works great on a drilling rig.

There good if you stand back the propper distance. Say 20ft ~(6.09600000m)

Back when bikes had points you had to remove the flywheel and replace or at least file the points fairly often. When I replaced the points or checked the gap I always checked the flywheel run-out. Now that bikes have electronic ignitions I rarely remove the cover. How often should you check run-out of the flywheel and how much run-out is too much?

Thanks all for the info and the link. I would love to see more of the bike with the side car. Looks like a wild ride with a monkey on your back. Do they run regular sections or do they have special sections? PS I couldn't tell what the frame was made of in the picture.

Might try a dead blow hammer (a rubber mallet filled with lead shot) or a regular hammer against a piece of soft wood.

Looks like an early 70's Cota 247 frame and tank.

Does anyone out there have a TY250Z two stroke aluminum frame Yamaha trials bike? What do you think of it. Is the engine the same as the Yamaha 4 GG - AxC = 74x58 on the new Scorpa? Does anyone know why it was discontinued, or where it was available?

[Call me a tight a*** or just STUpid...'cause I'm no mechanic....BUT...I just soak mine in a small dish of petrol...wring it out untill its NEARLY dry..and put it back. Bike seems to run fine..and I've been doing it for about a year. Mind you...if I'm really harming the bike in anyway, I would appreciate someone letting me know! ] Well I wouldn't call you stupid, but you would never get away with it in a dusty enviornment. The oil that coats the foam is what traps the dust and particles. If you ride indoors or just on grass you may get away with just the foam for a while but eventually your engine will be ruined. If you are a tight a*** just use motor oil to coat the filter. If you are really a tight a*** used motor oil would be better than nothing. I suggest you get some air filter oil. Put your clean filter in a zip-lock plastic bag pour in a small amount of oil. Squish the air out of the bag and zip it tight. Squeeze the oil around into the filter until the foam is evenly coated. I have used a rolling pin with good effect. You can use paper towls or shop rags to remove any excess oil. I suggest you do it quickly while you still have bearings and some compression left.

My friend with the new 04 called the dealer to ask if they forgot to install the heavy flywheel because his 04 is so much peppier than the 03. A light flywheel in slippery stuff might not be the best idea.

The 04 comes with the new and improved ignition system. It was supposed to come with a flat skid plate but I think, at the last moment, it was changed so it is now an option. I have a flat skid plate and it is very nice. I think that the air box is water tight. Any way I haven't noticed any water or mud getting in. I like the bike very much. That statement though comes from a rank novice. I rode a used Monty and a Beta several years ago and those were the only ones from which I can draw a comparrison. The fenders attach with nylon screws. That has saved me from buying a new rear mud guard several times now. I like the tapered bars (no cross piece). All in all the bike is very nice to ride.
