17 500 RR-S Throttle stepper motor adjustment

This info was given to me via the sherco forum and is the most usefull info i have had for this bike and the throttle hang. I would have sold it for the throttle hang issue but now its normal again and makes it A great bike now. ................................................
"Synerjet Models have an idle up function to reduce engine braking. This can cause bike to idle up and speed up down hills. When bike engine beds in some bikes may end-up idling up. There is a torx bit on top of the throttle body you can adjust anti-clockwise about half a turn and that should fix it.

I tried much less than a half a turn....probably 10 degrees, and it seems to have helped....in the garage.

Once I finish the fuel pump I can test it.

Seems a shame Beta dealers and their tech's don't know this.

On sherco forums there is much more info about the Synerjet system Beta info is sparse at best. "The Kran" are you running one of the plus maps or the std map for idle ? On the 2018 there is no option for the plus 300 anymore, plus 200 is it.

ktm xcw have thermostats even the 2 strokes. so more lies from kranman......back to dominating your forum with all your truths.  I know   you are never ever wrong.

Right, an XCW in Austria where it is made, is called an EXC. 

I don't guess, and it's not an opinion.

      The do it all bike doesnt exist, I know that, but Im looking for something pretty damn near close to it. My dilema: I live in Mexico and It is one of the most biodiverse places you can possibly think of; I can ride at 12,000 feet between pines, the next day shred a desert, and the last day be in a tropical forest. Any thoughts on a bike that you may think can handle all of these relatively well?
      Gracias amigos!

      I have a '13 Beta Evo 4T trials bike that likes to backfire on deceleration, it's pretty annoying. Looking at the parts book, there is no gasket, o-ring or anything else that goes between the exhaust port and the headpipe. The  headpipe isnt deformed or damaged, nor is the sleeve at the exhaust port that the headpipe fits over. Does anyone else have the same problem? What did you do to fix it?

      I just picked up my 2018 Beta Evo 200. The dealer included a few things in the box, such as the owners manual CD, a liter of premix oil, the rest of a liter of tranny oil, and a horn and a speedometer.
      Why in the world do they included the horn and speedo? The horn looks to be barely worthy of a kid's toy car, and the speedo might work on a bicycle. Why not skip those two valuable parts and lower the price of the bike by a huge amount, say $5?
      Does anyone have a use for them?

      This is my first post so hopefully I have this in the right area.
      So I'm looking to buy a new bike in a few months and can't decide what Beta to buy. I am going between an xtrainer, a 300rr or the 390rs. I know they have slightly different areas that they excel. I am coming from a 1998 xr400 and an xr250. My question is do any of these new bikes I am looking at have good off idle torque, like slow speed tractor torque. Both my xr's could chug along and climb almost anything but they are heavy and getting older. I dabbled in trials for a bit so I really like the low end pull of thoses 2 strokes, but I also have had a few mx bikes that had nothing down low. What are the beta 2 stokes like. Also does the 390 have a pretty low first gear if I go the 4 stroke route. I ride some pretty rough single track in Georgetown ca if anyone is familiar with that. Lots of switch backs and no room to get speed over some of the obstacles. I am more of a technical rider, don't do much high speed stuff so I'm not to worried about the soft suspension of the xtrainer. 
      For backround I am 200 lbs, 6ft, I'm a decent rider but don't race or anything. I have had loads of Japanese bikes and I am wanting to try out a European enduro, this would be my first new bike. Hope the post isn't to long. Thanks

      Up for sale Ohlins  TTX shock and RXF48mm forks & Brembo front brake assembly off of a 2015 Beta  250rr. They are from the Boana racing team, sprung for a 175lb rider. This is a great opportunity to grab a very rare Ohlins set up for your Beta! I am a 145lbs, so unfortunately I don't have the money to have them set up for me, I am just looking to get my money back. I was really looking forward to using them, but some times life gets the best of you, lol. Hope they go to a good home, where someone will get use out of them!
