Jet and rollers?....again

Right I finally got the variator out so I need to order my rollers. How do I determine what weight rollers I have so I can figure out which weight I need to order to go with the new exhaust and jet size? What sort of weight should I be looking for?

I removed the old jet and it was size 70, so which jet sizes would you recommend I order?

The pipe I got is the chrome stage6 race replica and its going on a minarelli horizontal a/c 50cc

 

u tried the search geez?

 

I have indeed but everyone is different lol

I understand that its quite a triel and error process anyway but I just need somewhere to start.

 

order something like a 72,74 and 76 jet....

and either look on your rollers for the weight written on them or weigh them on some kitchen scales....

probably order a few sets of weights starting at half a gram lighter

 

thanks dave

trust me to have rollers that dont have the weight written on. I dont have scales either so I think i'm going to have to nip into woolies and use the ones in the pick and mix section

 

:w00t:

be sure to get a few try before you buy sweeties :rofl:

i just walk around eating them all :rofl:

 

well of course! you just got to do that. Its almost law :rofl:

 

Right ive weighed them and they are 5g each so i'll order a set of 4.5 and a set of 4.0.

Are jets standardised fitting? Will this jet fit my standard carb?

depends what carb you got, some are 5mm (mostly aftermarket carbs)

and some are 6mm (mostly std fit carbs)

Note i did use the term "mostly" before someone says "my carbs aftermarket and uses 6mm jets!!

have a look on your carb, the make, size and model number should be stamped on it somewhere...

for example my carb has Dellorto 20.5 PHVB.

 

I took a chance and ordered 5mm and suprise suprise they don't fit.


:rofl:

 

yeah thatll be a std fit carb then

you should of posted up your carb model and size, and i could of told you which to order
