Absolutely, it's quite possible that a couple of companies have shared designs for reduced cost/compatibility like car manufacturers do, also it may make it easier for aftermarket component makers, as one design like that of a cover can be used on a series of machines.
All good in theory, yet has Greeves sold a bike? Seems they claimed a lighter motor, as with the others. Personally, I am not sure where exactly one will start trimming the Sherco motor without turning it into a time bomb similar to a gasser. Oh yes, one can trim everything untill it breaks!
One only needs three gears really, 1-2 in the sections, and 3 for the trail! I heard Montesa did that at one time! Just how light do you really want?
The bikes are soo speccalized right now that noone else wants them, not even a farmer!
Personally, i think some of these old gits are rotting old f--ksticks. Although I have only ridden trials in this decade, I have ridden both formats under the NATC rules in place here, which closely follow the WTC/FIM rules.
I will be the first to admit that I am old and out of practice, cannot hop with the kids or more aggressive riders, always say I am like a good dog, like to leave my mark in every section! Take my dab and swing the bike if needed, or take a second to study if I become snagged. We are not just riding burns here, there are few such sections that one flows through as in SSDT ! Fact is under the strictest of observers, even a momentary hesitation can get you a 5 under no stop, even with a perfect ride! Totally up to interpretation with no real guage for it for most. Can be total BS!
Really p****d by overzealous observers at times. Clean or 5???? Screw that. I could really p*** off a few being strict on our rocks. Totally not the intent of a fair trial in most cases either, so everyone just fudges to their own level. Again total hogwash! So at the stop available level, I can still compete, take my dabs, get my breath, carry on, even without being a superstar. The day usually depends more upon who is worse, not who is better, in our club.
If you want to make it tough, just hold the upper class riders to the no stop, let them hesitate, hop!!!!!! If the front spokes stop turning, you are busted! Screw them!
So I can take a fair and tight middle section and make the likes of Bou hop the tight corners on the rear, cause the front cannot stop, yet then even the sideways rule could come into play again, wheels must progress forward with the course. Just nitpicking BS, as one can build really tight courses. This can get really technical and ugly, but it can be done!
I did notice a little water in the carb but figure that it was from all the washing I did with the tank off prior to removal. Yesterday, I dumped and air dried the gas tank and gas can plus cleaned the carb again. After warm up with fresh gas, the result was the same. It sounds just like it is running out of gas at 4 to 5 turns out on the mixture screw. At 3 it dies. The fan cycles a lot even though it is only in the 80s and bogs if the throttle is hit quickly. I don't see any signs of vacuum leaks. It certainly was not rich before this issue. I have a 34, 35 and 36 pilot so I could try a 35 but I don't know what could have changed. Does CA reformulate gas mid summer?
One thing I have found is that sometimes the culprit is impossible to spot! The slightest piece of sand can restrict the pilot jet, so passage of a fine wire through it is recommended. Same with the other small passages.
Vacume leaks are possible, even through the crankshaft seals, even yet a restriction in the tank or needle flow could lean it out. If you are satisfied with the fuel flow to the carb, and a triple ck has revealed nothing, a carb swap and even closer inspection for vacume leaks may be neccessary. And yes, I am pretty they use alcohol induced fuel all the time, same as here. Should be 10% or less.
2002 2.9 started to develop a rolly lean sounding idle. It seemed to come on slowly. Oddly it was not affected by the mixture screw and did not produce any serious lean symptoms like big knock or bog but did get some minor knocking. Off idle performance was a bit weak and less predictable but otherwise performance was normal. I did a basic carb clean followed by a major carb and air box clean but it is still much the same. Mixture screw does not seem to make a difference. Any ideas? Could this be bad gas? The only odd thing is that I run a 33 pilot but have been running it for a few years with good success.
Most common thing would be water(condensation) in the tank. Empty it into a cut, clear plastic jug. Only takes that drop you may never see in the bowl of the carb. You can carefully break the bowl over a glass container, maybe!
Also be sure to fully extract the pilot jet to clean and blow(backwards) through the 2 little holes in the carb bore with cleaner, needle screw removed. Ck Banjo filter!
I have had to go richer on the pilot in recent years on the later bikes, which I muchly attribute to the oxigenated fuel. If you are having to run 3.5 or so turns out on the screw, you may want to go to a 35-36 pilot jet to get more in range.
Just as a reminder, these things are really just a token of appreciation. Sometimes the smallest things are the dearest as time passes. It is all relative, and honestly, there are some clubs I would rather see keep more profit from their hard earned efforts, as all is generally recycled to the sport.
I would like to see Pat contest the SSDT, and bring back some t-shirts for us! I do like to collect them from various events! Might make a good support item!
For Sherco to make such changes without proper development would be unthinkable. I still think the whole Greeves thing was just a front for development! How else does Greeves majically appear up with Sherco motors. How many they sold at that price? Anyone seen one?
Suffice it to say that an incorrect input(due to icing, in the clouds) to the flight control computer can put the autopilot off to an extent and the aircraft in an attitude thay may be unrecoverable.
Airliners are not designed to be aerobatic, and will not withstand excesses of speed or stress. Not to mention the simple extreme stress that may be encountered in ANY thunderstorm! It is dangerous stuff! Add, limits can be risked just to stay on the company schedule!
Hmmm,wood and canvas wings with jet engines(those early Nazi turbines detonated by themselves) built into the fuselage, sounds like an accident waiting to happen.
Not sure if any canvas was on it, seemed mainly plywood skins from the shots taken. Really thick leading edges and such, all well formed.
Supposidly much better radar absorption along with the low profile and heat signature, yielding less reflection than a metal surface. May tend to hide or disburse the underlying structure!
Yup,Copey,those Flying Wings were very unstable (dangerous even) and I doubt it could even be flown consistently in those days.
The Americans canned their FW projects in the 1960's after 20 odd years of testing and development .
It was only the vast improvements in computers in the late 1970's ( to aid as flight controls)that resurrected the Fw aircraft.
I think National Geographic and Grumman have re-built this Gotha/Horten for a new documentary so we might get to see if it can fly (don't hold your breath though).
I seem to recall there is a ruling in the U.S. that if you built it yourself then you can fly it yourself and this applies to anything from microlights.... upwards???
Well, there was a bit on the MSN today, stating that Northrop-Gumman(Skunkwerkz) is planning upon building a full scale replica of the(last remaining in US hands) Horten 229 to test its effectiveness against radar of the day. (add today!)
Seems the thing was mostly composite structure of plywood skins, tubes, and some carbon bits! Awesome, just could not fly wot a crap! They can fix that, today!
Hummmmmm? Wooden Wonders! Worth a current day buildup?
OK sherco have managed to stop water getting in the air box by moving it to where the tank used to be , but how will they now stop water getting in the fuel tank ???
Yes, fact is they were planning some nasty s---t! Far ahead of their time in many respects, yet the flow of ideas kept many valuable developers at home and away from the Eastern Front!
Took real computers to make things like a flying wing really work.
Unmanned aireal vehicles are quickly becoming a reality in this time, why waste a pilot. And even in the most modern jetliners, the pilot can pretty much just sit back and monitor things as even autolanding systems are becoming preferred by the "Company". And with very precise GPS and ground referance equipment at hand, along with automated systems, one can land in some really bad conditions , add very safely, and all automatic! 3D computer enhanced vision is the latest thing on the pilots screens.
Seems most if not all of this technology was resisted for years by the certifying agencys like the FAA and others. Yet the dam has broken! And the good stuff is getting out there.
Bottom line, I can navigate an aircraft anywhere, and very accurately, with a full color moving map GPS unit that will fit in my hand, fit on the column or panel, has all the info, including weather maps and radar if you want it! Not bad thing to have if you are on top of the clouds wondering where the ground is!
I'm not sure about folks competing at the nationals, but I think the sport has two issues that are really holding it back in America. The first is cost. While the bikes today are really unbelievable and well worth the asking price when you look at the technology, they simply cost too much to attract a wider base on the entry level side. And, because of the small size of the trials community, there is a scarcity of used bikes that keeps that option high priced as well. I'm really hoping the success of the economy models that GG and Sherco sold earlier this summer, opens some eyes to the marketability of a less expensive model. The second issue relates to the importer/dealer/parts and accessories supply issues. I've talked with a number of folks who attempted to come to the sport from other hobbies, and were amazed at what most of us go through to find a bike and then buy the parts and accessories to keep it running.
Very different from say motocross or karting.
All that said, the trials community is a great bunch and the folks involved on the business side are undoubtably doing the best they can with what I'm sure is a very difficult situation.
I know where you are coming from, yet there are lots of very competitive bikes out there(from this decade) at reasonable prices. And I really cannot think of too many things that I could not pick up the phone and have delivered to me within 24-48 hours, many parts are interchangeable with other bikes even.
Motocross, Enduro and CrossCountry are all HIGH IMPACT, sports! If you take a good spill, chances are it may well take more to fix you than the bike!
I have a good friend at work that has two kids now into Karting. We work on them, one a 50cc, another a 100.
Talk about too many rules and regulations, expensive overpriced crap to compete on a high level! All these computerized thingies and such. Oh and then the protests on motors, and teardowns and such, the overzealous dads with too much money, list goes on--insane! They try to make a kids cart a NASCAR piece almost, just not for me!
