6:32 is not the choke but the idle manual adjustment. Choke is on a cable from the left handle bar to right side of lower carb. The cable pulls a slider to adjust choke manually of both carbs simultaneously. But great video to remind us. I have 2007 GT250R
Hi I have gt125r, I would like to change to manual pitcock which you can on and off, instead of vacuum pump. Is it possible. The reason for this is I have heard vacuum pump is not reliable, if diaframe get damaged, fuel goes into the engine and create a lot of problems. This why people change to manual pitcock. Please advise on this, thanks
Can you just use a fuel tap from the tank with fuel line strait to the intake on the carb as I think my fuel switch on my tank dont work as no fuel is being circulated. Do you need the vacuum system for it to work?
Hi don’t have vid but still can help just explain me what the problem is and have have your bike is running i deal with them a lot and will explain what to do just need to know what’s going on with bike??
@@r91motorswelcome79 hello can u tell me what is a problem when I ride and reach around 9-10 k rpm engine chocked only when it's hot. When air filter it's on airbox same but on cold engaine . When I remove filter it's OK but only when it's not hot
@@tomektedorowski5619 could be two options air leak or something to do with fuel!! I think in this case could be your little fuel tank valve more rpm you give the more it should give fuel but sounds like there is not enough fuel going on high rpm check the vacuum pump all hoses for any cracks or any damage what can make air leak if all good replace your fuel tank valve and filter not expensive maybe filter with valve around 25£ in hyosungs this happened quite often hopefully it helps keep updating
@@tomektedorowski5619 and why is happening on hot engine because hoses or any rubber seals when they get warmer they kind get a bit bigger like stretch a bit and that can make air leak or your valve not working on full
I have a gt250r and installing a gv250 motor, but the gv 250 has two exits from the cylinder head I know one connects to the vacuum pump but can I seal the other? Or should I have a y connect to connect both? Like the one in your front cylinder
@@r91motorswelcome79 ha fair enough, and my bike has not run for two years, changed the oil, the old fuel and the fuel line and filter and now the bike revs really high at 4 thousand rpm and dosent drop down, and if I rev the engine it takes ages for the revs to drop back to 4 thousand rpm,
Hamish Graves just did you check the accelerator cable or choke sometimes they stuck maybe check them and put some W40 but if they are fine clean carburettor but maybe you done already. and make sure there is air flaps two off them make sure they close properly sometimes can get some dirt in it and gives to much air like in cold start if all is good just let me know I will explain you have to adjust carb!

Awesome video actually really helpful.
Especially that first hose, I was getting worried I had lost parts 😂
Thanks for the information well explained my friend 🤠
Damn ive been trying to figure that out for a long time thank you much 👍
Great video
You’re awesome, thanks!!!
Thank you my friend 👍

Also my 2nd air valve was missing when I got it but have now bought it but can find out how to hook it up. One of the 3 hoses I can't figure out.
Just plug and play put in order you think should be right if that doesn’t work then go different way

Yes vacum is needed that’s the way only
@@r91motorswelcome79 thank you
Can you please make a video how to adjust carburetor running on hyosung 125 cc....i really have trouble with that

@@r91motorswelcome79 Ok i will check all hoses and fuel tank on weekend
The "Vacuum-pump" is no pump, but an emission-device...
Emission-device? Can you explain a bit more please? As far I know that place works with valve and only with air flow which cylinder makes vacuum
1:25 it is vacum fuel pump.... And 2:52 it's a EGR valve
hey how can i find a new one can u tell me is it full name
@@devrikmavi0 This EGR, is more like SAI system, just injecting extra air into exhaust. And U can just remove it, as is useless.
@@AxelCSL thx

Yeah I know just close one down and see have it works if no good just try another one that’s what I did
Do u happen to have a diagram of vacuum hoses for a fuel injected model?
Unfortunately not mate but I am sure if you search for some manuals online will find one
Is the Aquila GV 250 engine the same as the Comet GT 250 engine?
Yes
@@r91motorswelcome79 thanks
What year is this. Mine is a 09 gt650r and looks completely different from this.
Hi this is 2016 and is only 125cc so I think it could be different
What year is that engine
Ali Alcala this is 250cc around 2007 to 2012 years not to sure but I replaced with 2016 all exactly the same!!
Hi Did you end up doing the carb tuning video?
Hamish Graves no not yet a bit busy! You got problem with carb??
@@r91motorswelcome79 ha fair enough, and my bike has not run for two years, changed the oil, the old fuel and the fuel line and filter and now the bike revs really high at 4 thousand rpm and dosent drop down, and if I rev the engine it takes ages for the revs to drop back to 4 thousand rpm,

@@r91motorswelcome79 I have a bike which sprays fuel out of one of the 2 holes on the face of carb on the air filter side. What could be the problem?
What does connecting these hoses do ?
Some of them are from fuel intake and also air hoses air and fuel just run around like circle
@@r91motorswelcome79 so would you say it’s worth doing ?
Way my motor don't have compeshe for one block enjin
Mtr hiosung ga ada pengapian biasanya apa, yg mati
Sorry my friend I don’t understand this language
Muy buen video.
Pero en español.
Ya con el video intentaré dejarlo igual.
