hi everyone,
yeahh i'm a new guy on this site and I'm from vegas. I bought a super pocket bike/mid bike couple weeks ago and he said its a x19. To me the fairings made me believe it's a x15. I can't tell and I'd be glad to know how I can distinguish the differences. I found a vin number on the bike and it was made in 2006.

anyways what I've done so far with the bike:
Cleaned carburetor and changed air filter
Fixed a stiff clutch
Added a kill switch because the guy I bought it from didn't have a key switch.
Tuned the carburetor so top speed 45+ now
Did a custom paint job.

Things I still need to do for this project to get:
Performance cdi
Get headlights and tail lights w/ integrated signal lights.(has anyone modded sidemarkers from Wal-Mart or autozone?)
new carburetor (22mm or 24mm?)
New exhaust
Street legal tires
New rear shock(advice?)

At the moment can't do much since I got surgery that made me unable to lift so its great garage project for me to do while I'm recovering at home for 3 montha.

Very nice, I like the paint job. As for advice I'm not familiar with mid bikes. GL with your recovery
Thank you :). the paint job is still a work in progress because of the fairings, i don't know if i want to add them or keep them off. and thanks for leaving me a response.

thanks for replying also. i've seen your bike a lot and i got to say, it is a very clean bike. I was wondering though about your tires! did you use the original rims? can you add different size rims like 12"? just wondering.

Thanks....The rims are stock 10" but the tires are high perf scooter streetlegal tires,,,Pirelli SL26 90/90-10 in the front and Kenda K13 130/70-10 in the rear.........My bike has been raised up over 2" aswell so the pegs dont ever scrape the ground...

If you mod the swingarm in the rear 2-3" longer youll be able to squeeze in 12" rims/tires

I would go with a 22mm on a 110cc stock engine, might want to get a jet kit for your new carb. Look on eBay motors/motorcycles/super pocket bikes for a carb, CDI, and hp coil.

Much better than white. I would stay in the 50 low profile wide tire. Like 140 or 150mm x 50mm x 10" or as wide as you can get. I put a 100 on my X18 front, taller and wider.

yeah the white was just primer because there was a huge crack on the fairing, so i fiberglassed it and bondo. but i'm trying out different tires. right now i'm looking for a rear though because i still have the stock tire on.

I got a 130/70-10 Kenda K13 rear tire on my X15.....Fits pretty good..

so i wouldn't need to do anything with the swing arm? because i'm probably going to get 130/70-10..

right now i'm moding my carburetor.

today i worked on the carburetor by removing the tab, 10 degree float and moving the c-clip, also cleaning it of course. results when i took it for a joy ride just up and down the street, i notice a difference. i'm not sure if others experienced a difference but i sure did. well since i've finish my custom paint on the body, i'm basically tuning for performance now and i'd like to get some advice.

oh just to let you know when i first got the bike stock i went 45+ on a straight road, i used my gps and my friend rode side by side with me and said i was going around 45-50mph.
tomorrow i'll do another top speed run and let you guys know how it goes with my stock carb mod and adjusted valve.

Nice job getting the mod done and the carb dialed-in....Now you need to do the headbreather and hp sparkwire mods............Youll really feel a difference after that

Oh I know the floatnowl restrictor tab removal mod works....Im the originator of the find and will never ever know about it unless you become a member here ...I found the problem back in 08 when an x22 I bought kept starving out after a minute riding wide open and when I released the throttle it died everytime til the bowl refilled it wouldnt restart either....Put it on my dyno I had in my basement and fiddled around with the carb and fuel flow from the tank many-many times til I realized where the anemic flow was originating from............

thanks cam2! as for the head breather and hp spark wire mods, are they diy or something i have to buy? Good thing i joined the forum because i probably wouldn't have known about the carburetor mod and get all this help. when i first rode the bike, it felt like it wanted to let out so much power but something kept it from going faster. doing the carburetor mod, made my bike smooth. but so far doing the time working on the bike is really going great.

Good to hear.....

The mods are DIY.........

Headbreather mod.......just requires removing the upper valvecover cap and drilling/tapping it for a 1/4" brass hose barb....you can also use double ended cable bullet connectors.....







Supplies needed......

[2] 1/4" brass hose barbs with NPT threaded end

[1] 1 1/4" PVC plumbing coupler

[1] 1/4" brass TEE

[6] small hose clamps or 10 heavy duty ty-wraps

5ft of clear fuelline

Tube of RTV silicone

Way to mount hose..Start out at the valvecover cap nipple and run the hose straight up towards the fueltank cover and over the battery tray towards the rear engine case vent hole....Tee in the rear vent hose into the one coming from the new vent.....take the remaining line and hook it into the third Tee nipple and run it high around towards the carb,,,,

Drill and tap the 1 1/4" PVC coupler for the second hose barb......On the end of the carb RTV the 1 1/4" PVC coupler to the end and let dry...Once RTV is DRY and stiff attach the airfilter

What the mod does.....

It eliminates trapped heat thats higher up in the head than the oil drain making it hard for the heat to dissipate....The hose attached to the intake powersucks the pressure and heat from the head and crankcase to allow the valves to run cooler aswell as the heat produced by the clutches causing harsh oil thinning is greatly reduced......With cooler running valves and thicker oil your engine will always have pep no matter how long you ride it or hammer on it............

The sparkwire mod is easy..............
