AEROX BOGGING OUT

06 liquid cooled aerox running 21 mm carb on a 95 mm jet with large polini open air filter, when I get to top revs I can feel the bike begins to hold back and then it just Boggs horrible untill I back off the revs do I need a larger jet or smaller one ? HELP !!

 

this is not the right place to post this.. post it in the workshop! anyways gonna reply this.. is it a 50cc or 70cc?

 

50cc & changed the carb to 17mm

 

well thats why it works like that... the carb is way too big.. put a 17,5mm on!

 

also put the airbox on!

 

Ah okay, thanks
also do you know a lot about tuning and performance ?

 

This is for my mate not me, but when he puts the airbox back on it runs worse :L
Not got a clue;

 

Jet should be about 75

 

same thing happened to my piaggio nrg.
put the air-box on and it should be fine

 

Have a look at the Pedparts blog, all the info you could want for an Aerox is there.

 

iv got a 17.5mm carb and im using a 90 main jet.. starts and runs fine

theres no point having an open filter ona 50cc ... dont think id even bother wit one unless i was running 77cc's

 

im running a 64 jet on my 17,5 carb LOL? why is everyone having so big jets on a 50?

 

The Aerox standard carb is a Gurtner 12mm with a 62 main jet. Pre 2003 Aerox's had a 17.5mm carb as standard running a main jet of around 75 I think.
I woyuld use this as a starting point.

 

oh thanks for the tip guys

 

Yeah we put the air box on ran a smaller carb & it's running fine; cheers lads

 

anytime mateeeeee

 

too big carb for the setup you've got?
