my 19mm was fater than my new 21:S?

right i have an aerox and noo im not one of those chavvy twat hu knows jack shit about peds but i have the following spec
hebo 70 kit
ginelli exhaust
hebo variator
kevlar belt
delorto 22mm carb
stage 6 manifold
thats all i can remeber at the minute

i used to have a 19mm delorto carb on with a polini airfilter and used to fly but i then braught a 22mm delorto carb thinkin it will make it faster but has went slower any ideas what jet size i should buy and use and also i am using a standerd airbox now

cheers for any help or advice given

 

says 21 in title then 22 in thread.

obviously needs setting up.

 

shit yh good spot its a 22mm and obviously needs settin up but any1 got a guidline to what size jet to start from ?

 

Try around 90??

 

i will buy ur 19mm

 

cheers wolfey

and how much u offerin?

any one know how to modify a standerd airbox aswell as i dont one the polini filter on as im trying to keep the noise down.
cheers

 

yeah ive just done some more modding on my airbox

goes proper now....and ive had to go up to a 80 main in my 20.5mm

yeah your box will need some surgery with a 22mm carb

 

you recon ill be better with my airfiler on then
and another quick question i have removed my oil tank and mix the petrol myself what mixtue should i be running? just need to now how much oil to each letre of petrol? cheers

 

erm i dnt mind price 30 quid including delivery sounds good to me?

 

would of been better to find this out before you started running pre-mix, but...

The oil to petrol ratio you want is 50:1

and if you dont know what that means, its 20ml of oil per litre of petrol imp:

 

cheers fo that capri dave,
how you feel bout meetin us 1 weekend capri dave so u can have a quick look at my nike and see what you think its running like ?
cheers for all the help

 

chris are you seling the carb or not?

 

not sure yet mate ill tell u later

 

i read somewhere on the internet that smaller carbs give better midrange performance because the mixture has more velocity goin through the reeds , is any of that true ?

 

not to sure about that one but could be true but midrange aint the problem its top end aint as fast

 

ahh kwl , cheers for clearin that up

 

We get more low end out of the big carbs on jetskis then the smaller carbs
A small carb will give maybe a bit better throttle response but less power everywhere

If you want to get good throttle response out of a larger carb you using ignition timing to do it
