Unhappy New to Pocket Bikes...Help identify my bike!

Hi Everyone,

I just picked up my first ever pocket bike used for dirt cheap but I'm having a few issues with it and I have some questions. First a small background on me:

I'm very much a car guy and instruct at a few different lapping schools in my area. I'm very mechanically inclined and very well equipped to work on anything. Having said that, I'm a fuel injection guy lol. This is my very first toy with a carb on it. I bought the bike to zip around in the pits to reduce the down tie I have running around between students from one end of the track to the other.

Here are my questions:
1. I have no idea what I bought. Can anyone help me identify the make and model of the mini bike?



2. The bike is having issues starting. The guy I purchased it off of says he used it for about 30min total and then emptied the gas and stored it for 3 yrs. I did a mixure of 32:1 and poured it in the tank. I put the choke on and tried starting it. The bike seems like it wants to start. It'll let 3-4 "pops" go, but will never stay started. Choke on or off makes no difference. I removed the spark plug and grounded it against the head to check for spark. Spark is there. I should maybe mention that the fuel line from the tank to the carb was all cracked to I replaced it with some car fuel line hose that I had lying around...it's a bit large but I zip tied it and it doesn't seem to be leaking. Could it be my fuel line? Where should I start looking?

I'm from the south shore of Montreal in Qc Canada...any online pocket bike online shops that could have parts for my new toy?

Thanks in advance for any help!

Re: New to Pocket Bikes...Help identify my bike!

Should have bought a sit/stand 43 or 49cc piston port scooter for the pits and there road legal, even in California, lol.
Where do I start?? There so many different pocket bikes, from 40" long to 65" long Super Pocket Bike. Two strokes, piston port, reed port, and 4 stroke honda clone engines. A photo would be great, photobucket etc. Is the cyld straight up or facing forward?? Does it have a 13mm piston carb or 15mm pump carb with 2 gas lines. Does the front tire read 90/65-6.5"??

MT-A1 Half Fairing Cagllari Daytona...…Its one of the later models around 2009-2011..You can tell by the whimpy 11/16"id exhaust pipe ....

This ones an 06 when they were capable of going 30mph out of the box...



Fuelline upgrade is 5mm / 1/4" id get a corresponding size nylon mesh high flow fuel filter too..One for a car is ok but yellow tygon from a mower shop is better......

Sparkplug gap is .030"

Fuel mixture is 50:1

Tire air pressure between 29-32psi

Top speed 21-24mph / 40-45lkph

Sounds like you may need to remove the exhaust pipe and remove the excess fuel then remove the carb to clean it out also reset the float then do the petcock mod.

You can get parts through ebay/amazon/ali-baba

Good Luck

Re: New to Pocket Bikes...Help identify my bike!

if CAM2 photo look like your bike, it is a Cagillari Daytona, Cag for short here. Also known as MT-A1 half fairing Cag and there is an MT-A2 full fairing Cag. and one RSR with rear shock, ( Pogo Stick ), and the Cadillac of all Chinese pocket rockets the Lucky7. I have all three, lol. If it is an A1, it probably has the 47cc engine, 40mm bore x 32mm stroke, they had 44mm big bore for those bikes cause the piston had a 10mm pin like the crankshaft. Then the factories which are many made a 49cc engine, same cases but a heavier 12mm rod end crank and 44m mm piston w/ 12mm pin, so a 49cc piston will not fit the 47cc crank even if you have a 44mm cyld because of the 10mm pin. I have a kit here for the 47cc engine, has a 44mm/10mm piston that fits the 47mm crank, that's a big bore kit. there is no big bore kit for a 49cc/44mm bore Cag eng. Most of these sellers lie like Dogs, selling 52cc hp Cag reed port engines, so check here before you buy anything, CAM2 will probably see this an give his great advice.

Since your in Canada, I would search on eBay.com.cn for Canada, cause shipping from America now can cost more than the part. It cost me $48 USD to send a 6lb small box to Canada. In Hamilton CN. there use to be www.tsunamibike.com, but I think they went out of business.

Thank you for the help so far guys! I guess I will start by cleaning out my carb and changing the fuel mixture to 50:1. Does anyone have a DIY guide on how to take apart the carb, clean it, and do the petcock mod?

Also yes the picture I posted is of my bike

Re: New to Pocket Bikes...Help identify my bike!

They are the same carb. Good for you to order stuff direct from China on eBay. Most parts sellers in the US won't ship to Canada cause it cost a fortune & a lot of paper work. From China works better for you. May take 2 or 3 weeks to get them, so do like me and plan ahead, lol. You can bore that carb to 14mm with a Dremel, bore the intake manifold to 14mm do the fuel knob mod, re-jet to a .70mm main jet. For less than $10 you can get a tiny gauge drill set with hand drill holder and drill the stock .64mm jet to .70mm, you can also buy jet kits online $10?? Plus a V-stack and hp air filter works too.

Re: New to Pocket Bikes...Help identify my bike!

Im more partial to these carbs...…They work a lot better on tool based engines..……..

https://www.ebay.com/itm/2-Stroke-47...8AAOSwv~xXDzXw

Theyre also a lot easier too keep an engine in tune too...No mainjet changes needed like will be needed on the floater carb so if you plan on using the floater carb and modding the engine be sure to buy a mainjet assortment pack too...Just by changing the airfilter changes the tune...Weather temps and humidity does too..


Good Luck

Re: New to Pocket Bikes...Help identify my bike!

The main hick-up is, the pumper carb has 2 gas lines, the 2nd is a return line, and your tank only has one gas connection, a lot of ways to fix that.

Yep quite a few ways to skin that cat...LOL..........One thing will be for certain is his engine will be able to be kept in tune way easier aswell as get better performance even without mods..




Reason being is the engine has to use its intake draw or "velocity" to draw the fuel up the venturi tube into the venturi to be drawn in through the reeds into the crankcase to feed the cylinder..

The pumper carb uses case pressure to pump fuel from the tank into the carb and is spurted up into the venturi where its effortlessly pulled into the crankcase into the cylinder to fed the need every pulse of the case..

To keep the engine in tune this is where its adjusted...Its the same principal as changing a mainjet except it only takes a minute or two to do so if you do a modification that requires more fuel be rest assured its very d0-able very quick without having to remove a carb just to have fun......LOL



If there was a floater carb I'd recommend for these lil engines it would be a 15mm floater carb from a Z50 Minitrail...Reason being is they have both primary aswell as mainjet also to mention an air/fuel adjuster screw too...…

I put one on the Razor electric converted to 49cc with CVT mini chopper...The best part was the carb bowl was a lot bigger was fed a lot faster and held a lot more fuel too...
