Online SD has some new MTA2 full body Cags, but the downfall is the 33cc engine, thanks to Al Gore and his, save the planet from smoking 2 cycles. For a beginning bike it might not be a bad idea. Then later you might get a 49cc Zen/Mitsu piston port engine, and Boosted306 can port it and or Cam2 can show you how to atleast double the horsepower, without breaking the Bank. Here is a stock electric start 49cc modded in to a Monster engine,lol.
Another place online minipocketrockets has 47cc Cag reed port engines in there bikes $329 + S/H and maybe Ca. tax depending on where you live. SD, I think its $319 shipped, not a bad deal, and hugh is totally Cool. Done business with him before. Thats where I got the 19mm Walbro HDA 223 purge carb for the Red Head engine.

Ok so i finally picked up the bike, guy said it was 49cc,but the plate on it says 43cc. The model number is XYQH098a. I tried to Google it but didn't get to far. It is a Chinese bike,but i would like all of the info i can get on this bike. I have a couple problems that i need to address. 1 I Have a gas leak but don't know if its the line,carb,or tank. Guy i bought it from just replaced the carb for the same reason with one from ebay, but idk if its good or not. Whats a good replacement carb? also i want to change the muffler/exhaust for more performance But idk which ones fit or where to purchase. help me out guys. Thanks

Sounds like you have a 2010 or 2011 cag.....Those bikes need alot of upgrades......Theyre built with many-many EPA compliant devices......

Hah, its pretty funny how many times I've seem Cam Answer this question.... These are all Cam quotes from a recent thread..
"""""""Youll need to disassemble the new engine totally,,,
race port the lower end case,,
add 4 extra windows to the piston and raise the sideskirt,
thin the rings a tad and deepen the ring channel 1/16", ~ Another thing you want to do is take 320 grit sandpaper and sand the sides of the rings to get rid of the roughness and widen the ring channels 1/64" on the pistons aswell as make it a tad bit deeper[1/32"] to introduce positive pressure seal on the rings....The other thing is grind the ring ends a real tiny mount like half of a 1/16"which is 1/32" so its ...1/64"on each ring end...That lil bit makes a big difference
index the piston top,polish the piston and the cylinder,
deepen the channels for the boost port/s to raise displacement,,
widen the transfer ports to raise engine displacement,,
widen the exhaust port at the cylinder side and reshape into a D shape,,
flare out the exhaust port towards the exhaust flange to match,,
add a 4 petal reedblock or super mod the stock reedplate/reedstopper and add a 1pc Polini green reed,,
stuff the crank
tighten the squish to .022",,
add a rocket key,,
lighten the flywheel
mod the clutches
get a jetpro pipe
run the 19mm carb the way it is on alky/methanol race mix""""""

Thanks J/Nipples.............
Whats funnier is how many people will do a search and get the answer but just because its not the same exact model as what they have most think the instructions are different for their bike like the differences between Honda,Kawasaki,Suzuki and Yamaha even though Suzuki and Kawasaki are the same company.......In 05 I had a KLX/DRZ onroad/offroad hybrid dirtbike.....
If you have a bike with a reed inducted engine those engines come on many-models...its the same style engine whether 43cc/49ccc and the mods/mod parts are the same..Cags/blades/gp-rsr,,pocket dirtbikes/pocket quads and sidecar racers have this style of engine
If you have a bike with a piston ported engine those engines come on many-models aswell which is mostly midbikes X1-X10 cateye,APC mini chopper/mini harley and stand-up scooters aswell..Whether 33cc/43cc/49cc they work the same way.......
There are cross breeds like pistonported cags and pocket dirtbikes but those piston ported engines are no different than the 33cc/43cc and 49cc piston ported engines above
Same goes for 4 stroker superbikes...whether 50cc/70cc/90cc or 110cc the engines are basically the same...The differences are cc size,,full auto/semi-auto and full manual shift engines.....They all operate on the same principal and everyone who inquires always gets the same advice aswell........
Its funny when I tell people to test their stator and they e-mail me asking what their reading is supposed to be........50cc-125cc...the stator numbers remain the same............
The only real differences between the chinese mini-motos,midi-motos and midbikes are the years theyre manufactured,,,from 2000-08 are the best models to get...The newer 2010-2011 models are a bit cheesier and arent as fun or as safe...........

I don't know that kawi and suzuki are the same company even though the 65, 85, and 125 2 strokes might be the same bikes just like the drz and klx pitbikes are the same with suzuki motors in both brands. They have products that are the same and that are different, like the klx 140 thats exclusively kawi. I don't know if the newer style 4 speed 110's by kawi are the same as the current suzuki 110's. but I'm sure the new 4 stroke race bikes are different from the companys...
Edit: I googled and found they were in a partnership until 2006 or something... But like I thought they're rival companys...
Usually people are forced to search and figure that out with those bikes if they want to learn about them... These pocket bikes get people lost though

So i got the engine off of the bike today, but i didn't take it apart yet. I've been doing some reading. SO far i understand the following and feel that i can do: Lightened the flywheel
Lightened the clutch by drilling holes in the arms,and polishing the bolt holes.
Widen the exhaust port to a D
And adding the rocket key(still have to do more reading on that.
Everything else i don't have a clear understanding of what to do.

HAHAHAHAHHA! This shoud be it own thread! Closed and Sticky'd!!! hah! AMEN!
Ya, dont worry Green turtle.. you now have a start.. Get going on a few then read up some more post pics and take it one step at a time... Way too much to do all at once... Well unless you have tons of cash and as much time as Cam, EPR and I have been finding.... lol good luck my friend!

Thanks Cam. How do you tell the difference between a piston ported from a reeded engine? My motor looks similar to the one in the last pic in this thread http://www.pocketbikeplanet.com/showthread.php?t=79475

You have a reed inducted engine meaning it has reed valves that controls the intake function...........Now you need to know whether its 43cc or 49cc....
these are reeds,,,on the left is stock and the right composite
This is a piston ported engine...The head sits straight up instead of angled........
It has no reeds

Only true way to tell that is to measure the piston correct?

Not really...Most times it can be told by looking at the lefthandside of the cylinder head....Take a pic of your cylinder head on the clutch side and post it...........
