  1. Well said Breagh. Cope is a Texas Tuechter. Twa bridies, a plen ane an an ingin ane an a" An a cup o Bovril.
  2. Was there a large speaker around the pipes playing music? It is practically impossible to hear the the engine and throttle blips when music is added. If this is meant as a training video then remove the music track as it defeats the purpose once you add music. Other than that good video and good riding.

    Cota Clutch

    Allyboy Where are ye riding in Glesga?
  4. From a few years back. She sounds like a freight liner in slo mo. This is good practice for lifting the front wheel and placing on an object or two. Helps with depth perception I find.
  5. An answer to a question that has never been asked. Why o why?
  6. Okay I give up! What is a "crank shockabsorber” ? Does it fit into the onumbtanium diaphragm?
  7. "At least if I get caught out on my Cessna I can get out and hand prop the thing! Happened more than once!" Was it in the air at the time? God your good!
  8. Nice, but that technically that is not a splatter. Back wheel hitting the object first is a splatter.
  9. Snow is like sex. You don't know when you are going to get some, how long it will last and how deep it will be. LOL
  10. We have all done this at some point!
  11. Three issues: Width, turning radius, tie downs. The trailer will be wider in this orientation and may be pron to be hit by a passing car on a narrower road. Due to the very short tounge one of the leading edges of the trailer will hit the back bumper when making a large turn. The ties downs will extend out making the trailer even weirder ( I don't see tie down facilitation on this trailer picture). What about a regular trailer that stands up. Go to Kendons trailers web site.
  12. Why the sound on the video ( I would call it music but it is not music). We want to hear the bike and how it is running. If we want to hear music we can go put on some music. Please remove the noise of what ever that tune is and just leave the sound track of the bike on the video. The video is great sadly the music makes one want to not watch it.
  13. Turn off Montesa’s (Bou’s) Blue tooth to his bike during a section...........
  14. So who wants represent their country to take an educated guess at the amount of riders in their country ??? No wild guesses but rather a educated guess based on what you know about trials in your county? Here are the countries I think know who are on this site. Please add your name if you want to speak for that country. Maybe Andy knows the stats on what countries are represented on this site? ANDY? Canada= USA= Scotland= Germany= England= Wales= Ireland= RSA= Spain= Brazil= Australia= IOM= Who am I missing=
  15. Curious as to what country has the most trials riders per capita (population) or just the most period? I know it is not scientific but rather based solely up the thoughts of members on the this forum. Should be interesting what the forum members come up with!
  16. Bliadhna Mhath Ùr to one and all

  18. You must still have the original tyres on that 2003 Sherco. I doubt they have even seen a rock since 2003.
  19. Cope You know fine well who wrote the article on the carbs/floats. You are just picking a fight. I will not get drawn into a discussion around floats moving up/ down once a bike has landed abruptly of a jump/rock. I have all the proof I need given to me by my mikuni factory training and through simple science. Bikes are not always parallel to the ground once they land and the fuel can and will slosh either forward or backwards in the float bowl causing a void and thus the floats will move down accordingly. If floats have no weight then why use a float? The fuel level goes down the floats go down. The fuel goes up the floats go, density yes but also due to their weight. If the bike landed perfectly square then the gas would not really go anywhere but just slightly compress thus no movement of the floats. BUT this is not reality, the bike usually lands front wheel first or back wheel first throwing the gas to one side or the other of the float bowl and the floats re-acting accordingly. This is the very reason there are two sets of adjustments on the brass tangs. One to control the travel up and one to control the travel down trying to isolate them somewhat from the movement of the fuel. I wrote a post a while back asking you to be honest with the members on this forum in the fact that you don't actually ride trials and have not been at an event or out practicing for around ten or so years yet you speak like you know all the latest about the bikes. I doubt you have actually seen a trials bike newer than 2003. I still keep in contact with many riders in the NTTA and they have not seen you riding ANYWHERE....... All one needs to do is to log onto the NTTA (North Texas Trials Association) web site and check the results going back for many years. See if Marks name shows up even once! You are Bench or magazine trials rider............ period. Bring it on. Or bury the hatchet.

    Carb Leaking Fuel

    I re-posted old article here below Mikuni Carb Setup By Billy Traynor 
The first area of urban legend is the two little brass outlets with the pink hoses attached. You may know these as the "over flow tubes". 
In reality they are not overflow tubes. While they may allow fuel to escape from them that is not there sole purpose of design. 
They are in fact atmospheric tubes. 
The main purpose of these tubes is to allow the fuel to reach atmospheric pressure. 
This means that when the pressure in the carb body (slide area) drops due to the negative pressure in the engine the atmosphere pushes (@ 14.7 PSI) on the fuel surface helping it go up the jets. 
There are two adjustments on the float level. 
1. The tangs set the fuel level. 
2. The little tab sets the travel of the tangs. 
The "brass tang" level should be set accordingly. 
Remove the float bowl and slide. Place the carb on a flat surface. Get down to eye level with the carb body and you will see two towers sticking up. One tower is the main jet tower the other is the pilot jet tower. Due to casting imperfections I will not supply an actual measurement. 
(This settings is visual and will vary from carb body to carb body that is why I will not supply an actual measurement) 
The brass tangs should project itself to the extreme left hand top corner of the lower tower or pilot jet tower. This sets the float level. 
We will now set the little tab that sticks out perpendicular on the brass tangs. 
The purpose of this tab is to stop the actual travel of the tangs downwards. 
This is important, as it will alleviate many anomalies once set correctly. One must know that the small pointed plunger that the brass tangs pushes up acts like a light switch. The gas is either on or off. With this in mind one need only have this plunger move enough to allow the gas to flow freely and then close when the tangs act upon it pushing up. 
Think of this! When you land off a large rock the weight of the floats push quite rapidly down inside the float bowl. This is known as gravity. The extended movement of the floats downwards tends to do two things. It moves the floats way down inside the float bowl allowing more gas than needed and it also causes some of the excess gas to be pushed up into the jets and into the engine. It also if not set correctly allows the float tangs to travel down to far. 
It is kind of like being inside a fast moving elevator and when it reaches this bottom it kind of makes you bend your knees. In other words the elevator has stopped but you are still going downwards. So how do you set this travel tab? 
Adjusting the travel tab on the carb will not stop the floats from going down but it will stop the float level tangs from traveling all the way down. This is important as the further they travel the more they are likely to stick. 
With carb back on the table and the float tangs set to the previous mentioned setting (top left hand lower tower) you should be able to lift the float tangs about 1/16 NO MORE. 
This bit of play allows the tangs to move away from the plunger jet safely. You will notice that the plunger jet has a springy feel to it. This is allows the float level tangs to still travel up and press continual against the plunger jet for a good seal. The first contact of this plunger will not necessarily close the plunger jet off that is why there is some additional travel afforded. 
The bottom line is that if the gas is coming out of the atmospheric tubes (overflow tubes to you) then the gas level is way to high to begin with. It is not that they are not shutting off it is purely that they are set to high. Keep in mind we are taking about the bike in static upright position with or without the engine running. 
The other thing I would highly suggest is that the pink hose ends be cut on a very sharp angle and small holes placed in the pink tubes. This will help alleviate the siphoning action if it does tend to flow out of the tubes. After all the levels and tangs are set correctly. There is still the possibility that gas will come out of the tubes in some rare circumstances. By cutting the ends of the tubes on a very sharp angle and piercing small holes into the tubes that siphoning action is somewhat cut off. This siphoning action can even after the floats have settled down keep it self self-going. 
Also you should withdraw the pivot pin (the pin the float level pivots on) about 3/8 of an inch and pinch it with some side cutters about 1/8 on an inch from one end and then slide/push it back in. This notched pin will help it stay put in its housing. 
These pins tend to vibrate out and hit against the side of the float bowl (look at the inside of the float bowl for witness marks to this happening). 
One other area of concern on the Beta is the two vent hoses coming out of the engine are far to near the float bowl. In fact mine were pushing against the float bowl this caused excess vibration into the carb body, which in turn plays havoc with the float levels. 
I solved this by cutting the cable tie and having them go around the carb float bowl.
