Try Hugh at SdScooters...Other than that its gonna be a lil difficult finding them unless you buy one used from your local craigslist...Good LuckHello everyone, I'm new here to the forum. I'm on the market for a pocket bike for my son and was wondering what's a good site to purchase from? thanks
Sounds like you have a 2010 or 2011 cag.....Those bikes need alot of upgrades......Theyre built with many-many EPA compliant devices......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
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 flywheelHah, 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""""""

HAHAHAHAHHA! This shoud be it own thread! Closed and Sticky'd!!! hah! AMEN!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...........
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....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
