Thanks, Paul & everyone. I did as advised, and a 5/16" ball bearing seems to match. I was able to find one of those at Orchard Supply Hardware. One thing, though, it looks like the two push rods are different diameters. I measured the outer rod that pushes on the pressure plate, as I could not get the inner one out. The inner rod looks like it is a smaller diameter. Anyone remember if their clutch ball bearing was the same size as the outer rod or inner? Paul, I do not know why my email address is giving problems. I have a received a few emails today. Thanks for catching me on this board, though.

I somehow lost the ball that goes in between the two clutch push rods. Does anyone know what the diameter of the ball is? I am hoping to find the right sized ball bearing at a hardware store. thanks.

Update about my fuel mileage. I did a ride this past weekend that was rougher than the prior, and I received about 17 miles per half gallon.

I checked my gas mileage a few weeks ago on a trail ride in the mountains over here (Sierra Nevadas), I received about 25 miles per half gallon. This is on an '02 sy250 scorpa with a long ride tank. I had a '91 or so Fantic 305, and the mileage was about the same.

Does anyone know if there are full length fork guards (the type that extend up and protect the outside of the stanchions from crash damage) that are mold fit specific to these Paoli forks? I have seen a one size fits all brand, but I am hoping for some that fit right. Thanks for your help.

Does anyone know if the tyz250/Scorpa engine shares parts with any of Yamaha's non-trials models? I am specifically looking for clutch plates. I am hoping I can find those parts at the local Yamaha dealer (USA), where my sister works. Thanks for your help.

Can anyone recommend jetting for riding an sy250 at 6-7k and 10k feet elevation? There is also one of those screen type spark arrestors installed, so the exhaust does not flow as freely anymore. I have some upcoming rides at those elevations. Thanks in advance.

I disagree. I see your arguement being valid, from a street biker's point, especially harley people. Groups like the Blue Ribbon Coalition, CORVA, ORBA, and the like, have done more for off roaders in one year (probably even just one month), than the ama has in its entire history. I have yet to find one single land access issue that the ama has won or fought for us. Maybe someone here knows of one?

I tend to agree considerably with what some are saying that trials does not fit the general American mindset and culture, motorsports wise. I don't see how trials will ever become much more popular than it is now. I believe one of the main reasons for lackluster appeal to the general public, is the bikes themselves. When a person sees one, that is the first thing to start the criticism and lampooning. Three of us here in town just bought trials bikes recently, but not really for any of the reasons anyone is citing for lack of popularity. Initially, I joked with them that we probably boosted the US trials population by 10%.

Does anyone know if the sy250 shares jets with any other make of motorycle? If so, I am hoping I will be able to buy them from the local jap. shop. Thanks.

but it doesn't look as gaye as those trials tights!

I hope the bike makes it to production, as it looks like the type of bike that I have been complaining about manufactuers need to make. I have encountered a number of other people who are looking for something like that, also. It looks kind of tall, though, and that guy looks like Shemp from the Three Stooges. The frame design looks seriously flawed, however. The swingarm area and that whole member needs to be beefed up considerably. I also think that they need to build a cradle type of frame, as people are going to be trying to jump a bike like that.

How come everyone seems so hostile towards, and picks on Mich Lin? Is there some sort of oppressive pecking order in trials? This reminds me a lot about school, when there would always be at least one nerdy type person, and the whole class persecuted them.

The Honda enduro bike and it's ilk, are not true trail bikes. Those machines are race bikes built for speed. They are fire road burners, and often times they become instruments of vandelism. The singletrack that these bikes run in enduros, are not techinical, but are more of groomed trails that one can often times run 20-30 mph on. When the terrain truly does become technical, those bikes have to be forced through, and more times than not, cause immense amounts of trail damage. The sad part is that nobody cares when that happens. It is all about twisting the right hand. Riding enduro bikes through that type of terrain verses a trials type bike, is like using a butcher's knife to do surgery. I have found that a trials bike has the best foundation currently available for a great trail bike. It just needs a bigger tank, and a seat for some people. As far as the bike popularity comparison between us and the Euros, I don't see that as a valid analogy. We have far more land (at the moment) to ride on, than they do. Do they have vast national forests and blm type areas to ride on? I can see why the current incarnation of trials bikes are popular over there, because that is the best machine available, to make the best of a limited situation. Over here, it makes perfect sense to have a machine with a little more versatility. It is different here in the states. We have more riding options available to us. I don't see what the fear is all about, regarding the current bike form changing. As Mich said, the broader the appeal, the more bikes sold. And what do companies do with all of that money made? Do they deseveredly put that money back into R&D for their largest customer base, who all at best happen to be weekend amatuers? Of course not. These companies will predictably funnel the money into their race programs, which will trickle down, and mostly benefit the minority hardcore riders. The same dubious thing happens in enduro racing. The lowly C class has by far the most entry fees gleaned, but most of the money and focus is given to the handful of elite riders. It is nothing more than another form of aristocracy, a bourgeois plantation enterprise.

I was only paraphrasing what I read in some of the other posts in "Across the Pond," which someone(s) reflected on the current trial membership. I have only literally met a couple of trials people, and they are not "fuddy duddies." I certainly hope that did not rub anyone the wrong way. The reason why I make mention of the tank/seat issue, is because as an outsider/non-trials person, I have a valid and different observation on the situation of "An Example of the Problem with Trials in the US." As I already mentioned, if one wants a sport to grow, it has to come from the outside, and not exclusively from restructuring the way competive organizations and events are run. If one is satisfied with the status quo, then I don't see much of a foundation for discussion on the issue. I cannot see why making a larger tank/seat combo removable or interchangeable, would change a bike for the worst, as some here seem to believe.
