I don't think that carb trumpet will help you as it makes the outer diameter much larger and your rubber manifold won't fit it.
To me it sounds like you might have the wrong rubber inlet manifold on, there are two versions a short one for the 99 to 2005 bike and a longer one for the 06 to 09 bikes you can see them both here: Carb to Airbox rubber inlet manifold
Hope this helps

cheers
I just got my new rubber on tuesday from yourselves (really prompt delivery cheers)its the correct one ok
I ordered the trumpet today after speaking to the supplier, he recons it is perfect for my problem and has sold them before for the same issue, I did wonder about the diameter as it looks bigger to me.
I almost hope it is bigger as it will be closer to the diameter of the airbox
if this is the case I will get a hose to suit easier
the end of airbox looks all out of shape id warm it up with a heatgun and reshape you might be able to use a car radiator hose to make a longer pipe ,its poss its been over on the back and bent something
yes I think I will put a pipe up the inside and make it round as you say with the heat gun
the snout is square with the airbox ok it just the odd shaped side thats making things difficult
no idea how it got like this, the plastic is so hard theres no chance of it bending
Have just recently got my 10 year old an as new 06 125
great bike but terrible for getting dirt in the airbox after washing (my fault so will make a bung of some sort)
my problem is that after removing the airbox and carb for cleaning it just wont go back on
the plastic airbox extension is pear shaped to the silencer side, is this normal ?
when I offer up the airbox its as if the airbox snout is a good 10mm off line towards the silencer, therefore the carb rubber has to twist badly to the left to meet the carb. this being so short that the rubber doesnt sit square on the airbox and runs the risk of letting air in
I am going to get a new rubber boot to see if this helps or is there a more flexible pipe (and longer) that could take its place
think I will keep an eye out for a Sherco or Gas Gas and will certainly be buying on condition as you recomended
understand the Beta is a quality bike but think left hand kickstarts is unnatural and reminds me of a 1978 Bultaco
There are a number of differences. The 2008 GasGas had a new frame which improved the bike's stability and lowered the weight. The Engine is pretty linear in power delivery but has a lot of top end and you need to rev it to access the power. Keep on top of maintenance and you'll have few problems. The Kick start gears, specifically the "bart" simpson cog can go if you are rough with starting and if you have a problem with gears you need to get it looked at ASAP. That box is a work of art but if something does go wrong you need to get it fixed. It's the "trick" bike of the three easy to get the front and rear bouncing around and move in a section.
2008 was the last year of the REV-3. I think the bike gained the Kehin carb and it had the "slimmer" petrol tank. Only problems centred on the rear brake linkage which is a bit fragile. The engine is pretty strong low down but can be a bit "fuffy" as the revs climb. Basically it doesn't seem to "clear" it's throat as well as the other bikes. Doesn't Bounce like the other two either but a "steady" bike and could be made to dance in the right hands.
The Sherco was the "old" frame style as well. not as many around in the UK but pretty bulletproof. The problems with the Mains bearing's seemed to have been solved or were not as prevalent. A good 2T oil helps. The Airbox sits under the rear mudguard so if you break it in the wrong place you can have problems. Not as good as the GasGas at "Trick" riding but better than the Beta.
As for the 2009 bikes the GasGas is pretty similar but he Beta went to the "EVO" frame. PeterH summed thta bike up pretty well and the engine didn't "fluff" as much. Improved Trick riding as well as the new frame is lighter. The later the EVO the better the carbaration. The 2011 GasGas frame is more stable and the Airbox is cleaner and has improved the running of the engine as well. The New Rear Brake master cylinder is also an improvement. My Son went though the "old" kits every 4 months or so. the new one has lasted 8 and although it has failed is still getting the back end to stop.
The Sherco didn't change until 2010. This is a very different bike and size wise suits the younger riders. The only problem's I have heard of are to do with fuel delivery which affects a few bikes. Get a good one though and it should be OK. The 2012 shows where the problem was in that the Carb angle is now similar to the Beta and GasGas. the 2010 and 2011 carb's have a rather "flat" installation which seems to effect the float.
Lastly buy on condition. If you know the owner and how it is maintained even better!! If the bike you are thinking of finishes trials that tends to indicate a good level of general reliability.
mine was also a nightmare to start and then would not rev out
I tried all the things you have and more
in the end I took the barrel off (5 minute job) and found the exhaust port at the piston very coked up, 10 minutes gouging with a screwdriver let the biggest amount of rubbish I have ever seen out.
new head gasket and bike started 2nd kick and could pull me (19 stone) admirably round the garden
make sure the collector box is not blocked (you may need to cut the back out of it)
these wee bikes are bullit proof and the best starter bike by miles, don't give up
there is a dedicated pw site where I feel you may have a better audience and some very knowledgable pw owners who have seen everything and more
I have a Delorto PHBH26 carb which I have had from new
basicaly I am thinking of off loading it and do not want to mislead any one so am looking for some advice as to how good my memory is (and if the carb is of any use)
I owned a 1984 250 mono (first ones out)
For some reason at this time it was the thing to do to change the carb to make the bike run better
I used it for a year then sold the bike but kept the carb
Is my memory correct and is this a thing anyone else remembers. I can't even remember if it was significantly any better than standard
had the ty 80 out in a field learning gears etc and there is a large amount of oil running from the silencer and in the air ending up as black spots all over the wee lads back.
obviously the first thing I think of is mixture of fuel. Currently running at 40:1 motorex 2t fully synthetic
I have just promised a manual for your bike to a man in Dublin today !!!
Is there anything specific you need to know ? I could scan pages and email them to you before I part with the manual
I will have a look i might even have another, but no promises as its been a while.
The side stands were rubbish by the way (made from the worst aluminium ever)
I had an after market one fitted, John shirt made them but you had to take the swinging arm out to get it welded on. No idea if they are still arround. But forget about looking for an original
125 Fan Stays On
in Sherco

looked at the wiring and it all looks untouched
going out today, will see if it stays on all the time
