delorto/ polini 25mm carb HELP (pic)

Hey my bike is on premix and im wanting to use the pump but was wondering where the oil pipe goes to on the carb.

it must be one of the ??? but i dont know witch

 

the other brass one next to the vac pipe mate.

 

Thanks mate, and btw will a 90 jet be ok witha a pm 172 kit and standerd air box?

 

wun't like to say mate, put it in to start with see how she feels and do some plug chops to be safe.

 

Well when i bought the bike it had a 102 with a open filter but i want to put the standerd box on, thinking of going to a 90

 

90 seems something like but your allways best runnin rich and jetting down, better to foul a plug than it nip up :thumbsup:

 

yepp, in the pm 172 instalaiton guide it says 88-90

 

is that with the std 20.5mm carb though or a 25mm carb like yours ??

 

25mm with standerd box. i have an open filter and it recomends 102-106 for that wich is what i have in atm but it eats petrol. it dosent say anything about standerd carb

 

yeahh open filters do use a lot more fuel, because obviously you have to run a much larger main jet...

 

yer, but dose 90 sound about right to start with for standed box and 25mm carb ?
