Zeez that post is old. Can't believe it has stuck around for all these years since I wrote the article. The fix works Cello.

Dirt Rider 86. It would help a lot if we knew your location.

The above not withstanding. Diaphragm Clutch: Radial energy being converted into Axial kinetic energy being converted into radial energy and being converted back into axial energy a BIG factor in this equation. All the above just within the clutch cases alone. There is a lengthy article I wrote on a trials clutch about 32 years ago on the original "Trials Action" Ian Johnstone site (the prior name to this site). Maybe I can find it and re-post it. Now where is my Tandy TR80 or my Commodore PC ?

Hi Dan.... Mount S3 pegs on Beta and play with moving them back and forth. Spilt the ergonomics between bars and pegs to get the best personal settings. Less impact on front steering and rear traction. Tune to taste 😎

Foot pegs in rear position with bars in original location you mentioned tried first ? Open up the riding cockpit ...

Mmm Interesting 😎

Bri. Southern Arizona is a BIG place. Where are you thinking of spending winters in AZ ? Our trials group lives and rides in the greater Phoenix area. PM me for more info

No need to torque the top fork caps. Once you tighten up the top triple clamps Allen heads they will keep the fork caps in place. Hence why you have to loosing the top Allen head screws before you attempt to loosen the top fork caps.

A thumb throttle on a EM motion is an accident waiting to happen. We should be encouraging experimentation as it takes the sport of trials forward. We should also respect those people and ideas that came prior and learn from of it Everything comes around full circle as there is nothing really new and earth shattering to-date. Like in the past the "thumb throttle" conversation will have its moment, debate experimentation will ensue and then slip into the long list of "what ifs". Its all good stuff and keeps experimentation alive.

This question has been brought up and tried several times though the years. A standard Throttle tube twists towards the rider, and the front brake activates in the same direction A Thumb throttle pushes AWAY from the bars and the front brake pulls towards the bars. The latter is VERY hard to do and control with any fitness on a trials bike especially at the higher levels Keeping the front brake covered with one or two fingers at all time whilst keeping your thumb on a thumb throttle leaves very little of your hand actually holding the bars It is also tricky to do full lock turns with a thumb throttle as your thumb is extended out. Hence why it has not been adopted Go try it out for your self. I guess it is the "Thumb Throttle" idea time for recycling again. I applaud the tthought process though. 😎

Hi Primodious I am looking to get a 2021 R3 Vertigo A service manual and a parts list would be VERY much appreciated... How can I get a copy from you? Thanks

The stock Beta Factory forks are not Tech forks. The Beta forks are Paioli. Check the Beta parts manual for details

What brand and weight of oil are you running in the 4T ?

Dan... Wont be the first time someone has installed the brass tang upside down. Seen that and worse on the VM 26mm Mikuni's on the Beta. How about a float install without an axle pin, or some holes drilled in the floats to make them lighter and the worse was connecting the gas directly to one of the brass atmospheric vent tubes and then could not figure why the gas was flooding out of the carb when he turned the gas on ?

Mmmm... As soon as you get off the idle the main jet is now in the equation.... Key word is IN the equation Why? Because the fuel has to flow up through the main jet orifice to get to the needle jet orifice as the slide moves up taking the needle with it... As the needle and slide get higher the main jet starts to have a bigger influence / role to play All jets (Pilot / Needle / Main) are in the equation once the slide and needle jet start to move up although at different contributions Be it a Mikuni or Keihin carb the logic is the same
