Re: x19 Super Pocket Bike Help!

To change the oil there is a 17mm nut I believe is the size on the bottom of the motor u should have the motor hot or up to temp to drain the most of it and u will also need to remove the lower fairing on the right side to do this I used a hole saw so I did not have to remove it everytime

The best oil well everybody had there own opinion but to break the motor in use a regular motorcycle oil the first 4 tanks make sure it is a motorcycle oil 10w40 cuz regular car oils won't work after that u can switch to a synthetic oil like Mobil 1 for motorcycles to set the idle u want it high enough to run without dying but low enough so its not racing the motor usually its the screw with a spring on it im not sure about your carb without a pic

And yes u can clean it with carb cleaner but I don't know why if its a new carb

Re: x19 Super Pocket Bike Help!

any 4 stroke motorcycle oil is fine really
if you spray it with water, dry it off or it will rust

Re: x19 Super Pocket Bike Help!

Def sounds like a carb issue sounds like its bogging on you

From what u describe the sound it is sucking air but I could b wrong unless I heard it

Do you have the stock air filter on it or did u change it to a different style

Re: x19 Super Pocket Bike Help!

i cant figure that out from your other thread i was talking to u on but try the new carb

you will have to get a jet kit for it most likely

and u may need to down jet it i tune it by looking at the plug i get at least 4 new ngk plugs from my local parts store and run it stock settings if it will run then i pull the plug and c what color it is

black too rich must lean out the carb

white too lean must richen up the carb

brown/almost cleanish perfect just right

i start by moving the needle clip in the carb up or down depending on if its rich or lean if i go all they way up i need a smaller main jet and so on

use a new plug each time u change the carb settings the screw is only for minor adjustments

i try to keep the needle as close to the middle as possible i think that is the correct way to do it i could be wrong tho lol but it works for me because if i got a hot muggy day i can mess with the srew a bit or move the needle a little to make it run better and if i got a dry cooler day i can also do the same

and if you buy a box then you will have enough plugs for the life of your bike lol

Re: x19 Super Pocket Bike Help!

I am using 20-50w racing oil in my X18, & a blue oil cooler. I put the cooler on the upper left side so it did not block air to the head.

Re: x19 Super Pocket Bike Help!

wow 20/50?
the hole that shoots oil to the head is very small, not sure that weight oil is good with the stock pump

Re: x19 Super Pocket Bike Help!

Its just 20w oil w/ the protection of 50w oil. I run my bike down the highway, wide open most the time. My Dodge Magnium V8 uses 5/30w.

Re: x19 Super Pocket Bike Help!

in california the oil probably thins out a lil with all the heat too no?
im probably wrong but heck, i tried. lol!
i use amsoil full syn motorcycle oil in mine.
once in a pinch i used there euro car syn oil......
worked just fine.
but it made the bike more expensive to fix, musta been the "european" in it!
lol just kidding!
i used to use their 2 stroke oil, but at 10 bucks a quart it got expensive.......

Re: x19 Super Pocket Bike Help!

epr, in cars and trucks the main thing (or one of)that determines oil weight is crank bearing clearance
older cars with worn or loose specs can use thicker oil, newer cars ive seen take 0w20 cuz the clearances are so tight, if you put 5w30 in that the crank or bearings would warp or burn up
our motors arent that bad but its tight in spots
