modded zuma fule isses "not with oiling isses"

[bclivewire]

ok I have a 2005 zuma 50cc reringed

modded are pipe and 19mm carb with 90 mail jet (stock air box with snorkel removed

after 1/2 mile or less it seams like it is running out of fuel

I back out of the throtel with in 2 maybe 4 secens it will come back to live

im runung the stock vacuum petcok

is there aney way to keed the stock petcock?

I haavent tried the open fuem cap trick to see is there is a vacuum in the tank....

I'm really not a fan of stock petcocks, so I'd ditch that but I don't know that you have to. Try the fuel cap trick first.

Could be the float height is set a little low and you're running out of fuel. Lines and filter look good?

[bclivewire]

hhooo float settings .... thank you I would not thot of that

this is way I like this forum

let me check that to

[bclivewire]

ok that is good info

but onn the zuma the petcock paced over the rear tire

it would be nicer to mave it to a more conveut pace

[rupert]

I *think* you are kinda "caught" though. The petcock should mount to the tank with a couple of screws through a kind of triangular metal bit, the only thing I could find to replicate that is a petcock off of a Raptor. You simply trim (or cut) a hole in the inner fender to let you deal with it, you do get the bonus of a "reserve" position, if for some reason you do away with the fuel gauge.

well I added lot od oil to the gass (note still running oil injction)

than blasted compreced air thoew the tank vent .. no issues there

[bclivewire]

well im going to run the tanj out than modd the stock petcock but drillind out the ports to inprove fuel flow

[bclivewire]

ok I have rum 10 gallen of gas throw my scooter but the oil is not going down

and whin I add oil to the gass it runs far stronger

I will try the 2nd oil pump next

ps this scooter has no oil smock at all

My 08 doesn't smoke. Unless you know something I don't you can't see the oil level in a Zuma all I can do is add to see how much I've used until the light comes on. 10 gallons at 40:1= 1 quart of oil roughly. Have you added to see how much it took to top off? If it wasn't getting oil it would seize. I've got around 4000 miles on mine and have not gone through 1 gallon of oil yet not counting what the dealer put in to get me home. 10 gallons of gas is like 600 miles if you aren't using oil you are in trouble

well furst off my side body work is removed do to the furst owners braking off all the mounting tabs

so I can see that little to none of the furst quort of oil has been used

as for my MPG it id under 50mpg by a long shot

is the aney type of mecherment for the oil injection?

like iedel for 3minnets get 3cc of oil out ?

[bclivewire]

got oil ... let it run for a minnet or 2 got 1 drop of oil every 20secnts

so pulling the carb next to ajust flote

[2stroked]

These oil pumps r made 2 put out the exact amount of oil the motor needs at any given throttle position all of the time. You wont see much oil leaving the tank. Only a drop every couple of .minutes or so.

Yes u can adjust the pump if it is the type that has a cable running from the throttle. U can see how here
