Hey , I have an on going issue with my 06 vespa gt 125 , I've had a full engine replacement, new carb , fuel pump , water pump and lots more but the issue persists ,
The issue is when my bike gets hot I will idle at traffic lights etc , when I go to accelerate the bike just basically bogs with no power but engine is running and is like that for up to 10 mins then eventually have throttle again...help me please , everything that can be checked or changed that could cause this ,has , its driving me crazy
Thank you

Hello there could this be something like the coil.as when it's getting hot it's starting to fail then as it cools a bit starts working okay. Or possibly pick up on ignition. Also float sticking in carb.good luck with it we have all been there keep trying cheers alan.

Thank you Alan, I'm open to any new suggestions as I've basically replaced everything but the chassis on my bike trying to find this problem , I'll pass this info to my mechanic as my bikes in there now as I've just had my new carb etc put on but it still had the problem so I left it in the shop

Ok I have my bike back from the mechanics after having a load of work done, my bike is running nice , seems responsive but!
When idle if I throttle too quick it will have no acceleration until I throttle slow to pull away...any ideas of what is causing this would be gladly received

Is the butterfly sticking on the carb?

Hey ironsloth, thanks for the reply, I have literally had a brand new carb put on last week so it shouldn't be that

Sounds like it could be over fuelling, when you give it some, does the note change at all, and it pulls away like it’s in top gear?

No , it runs perfect when it runs it literally just bogs if I rev to much at idle ,I am going to attempt to get a video of it

Sounds like the carb needs re jetting to me, it may well be new but it does sound like the jets are a bit big.

You have a jetting problem there l think !! To big on the main jet maybe 1st and 2nd could be your slow running jet maybe give them a change out and see But Hay l think it over jettet!! Slow running jet CHECK OUT!! Best foot forward soulboy74 🏴
