just hassle taking it off, and i still need to know if its m5 or m6

 

okay, i really need to know, im not going to take the carb off unless i dont need to as 2 strokes are so tempremental!

can someone please let me know by tomorrow as i need to order 1!

need the size and the thread sizee!

 

mate, they arnt that temperamental that if u simply take the carb off and put it back together , then it will start simple as, it will be your fault if it doesnt start. Its a 5 minute job checking the jet, no-one knows so far so just go and check yourself, it might even be a different jet , you never know !!

 

lol hes waited 2 days for someone to tell him the jet size...

when it takes like 10 mins to check yourself :msn1:

if your that scared of takeing the carb off...what you gonna do when you need to put the bigger jet in :wtf:

in the haynes scooters manual it says the yamaha yn50 neos has a 78 main jet
(But dont blame me if its wrong...weve told you the only reliable way of knowing)

 

your gonna have to take the carb off anyway to change the jet- why not get some practice in now

 

kk, having a look later, anyone know if its an m5 or m6 jet ?

 

okay, had carb out, its a 72 jet, and is m6.

so for a pipe you increase jet size by 5% ??

if so i need a 75.6 jet, so do i go 75 or 76 ?

76
