I have been thinking along those lines. I have seen a carb for a KTM 50 SX as it's the same engine but I'm not sure if it will fit in the frame. Also concerned as I need to keep the smaller inside diameter (15mm) for torque. The KTM one s 19mm so not sure. I'll have a look at the TY one, thanks

I have an old carb, same model with a metal slide. I've cleaned this up and used that but still the same. I've almost run out of ideas..thanks for your help though

This carb doesn't have a fuel mixture screw, it's the most crude carb I have ever seen. I can raise the needle via the idle screw but it doesn't seem to have much of an impact, it either doesn't tick over or it revs high. I can hold a steady low idle by using the throttle though which is odd. It's a plastic slide held in place within the carb body and a spring angled at 45deg pushes down on it. Dellorto SHA 15/15

No. It wouldn't tick over correctly. Took it to a shop and they said it was the left hand seal gone, replaced, still didn't run correctly. They took the head off and said there was play in the big end which was throwing the timing out. Full rebuild and still not running right - not sure this was the issue though. The original main jet was a 60 but I have never seen the bike run correctly on this. Carb I bought new had a 68. I have changed this back but still the same issue. I can hold a nice low rev off the throttle but not off the carb...I can get it very 'crisp' off the throttle but it wont tick over. It either revs its nuts off or stalls...this is killing me and it doesn't help my 6 year old asking every two minutes if I have fixed it yet

Came with a 68 main. Not sure if this is standard but it shouldn't cause the issues I have I don't think.....

I bought it from Eurocarbs and told them what it was for. I still have the old one and it does the same. It's not a cheap copy but it keeps sucking air through the top of the carb. When it revs high I can stall it by spraying GT85 at the carb top. I have eliminated all other air leaks.

Hi All, Does anyone know if a different carb (other than the standard) will fit on a Beta 50 Trials, air cooled? I have just bought a new Dellorto but it's no good, can't get it running right and these carbs are shockingly built. I know everything else is fine as it's just had a full engine rebuild - all seals/gaskets have been check for leaks. Pulling my hair out with this thing so any help would be great. Carb size is 15mm internal bore. Thanks

Great thanks!!!!!

Hi All, Does anyone have a wiring diagram for a Beta 50cc Minitrial please? I have a brown wire that I have no idea where it goes. Thanks

Great response, thanks!

Hi All, Are you able to still purchase spares for a 2004 Beta 125 Rev3?? I have done a quick Google search and I can't really find much info/parts for this model. I spoke to Trials & Tribulations and they told me to only look at 2008 onwards as parts are a nightmare from Beta.... Thanks

The deeper I get with this the more confused I am becoming. There do not seem to be too many TY's near my area (sub £2k) and Fantics are fetching top money at the moment which has pushed me down the newer style, but looking at Beta Rev3 2002, GasGas 270 JTX 1997 etc the parts seem to be very difficult to get i.e mudguards etc. My budget is around £1,400 - not a lot I know but it's all I have at the moment. Thanks for advice so far...

Yes sorry the TY is the 'mono'. Thanks for the comments. Is there any other that should be on my list that isn't? I need to be able to get parts easy as i dont havw much luck!

Hi all. New to trials and there seems a lot to learn and there is a tonne of info on here that may take a while to chug through.... Strangest thing I have learned so far is that parts are easier to find for an old Fantic than for a 2000 Beta 250 Evo3, especially rear mud guards!! Anyway I am torn between three starter bikes. Honda TL125, Fantic 200 and a Yamaha TY250 - all vgc. Anyone have any views, hoping to view the Fantic at the weekend. Looking just to play about at the moment to see if I really like it and also to ride with my son on his Oset. Thanks all!
