Nicw tutorial! It's cool to see this being suped up before adding gas to it. Maxxed performance from out the gate! I can't wait for that $10 pocketbike video. 😎
The rocket key is one of the best upgrades you can do.I take those engines apart all the time and rebuild them.I put them on razor drifters and they make fun go karts.
Great videos Im doing a similar build myself had a 49cc engine that was shot and it was just cheaper to buy a new one than order the parts needed. Did you ever install the electric start? Thats the one thing the new motor didn't come with, may swap over the old unit.
I really hope you make some video's on that engine running, a engine run-stand would do the trick, I'm going to build a trike with two of those 49cc 2-stroke engines on it, and a electric hub front wheel for a reverse, lol, awesome video and info, thanks for sharing.
I too hav an exahust system. Its a tecnigas exhaust system but i will have to chop and re weld and replace the manifold with a mini moto 1. Also do we need to do any thing with a clutch variator or do theese engins not have 1. Also im intressted on gettin the rocket key. Also could you not take all the fins off the fly wheel 2 lighting it right up sure it will add to the performance. Also you ever thort about a transmission box on.
Give this video a LIKE for me!! Some of you are saying retarding it like I did could damage my engine and won't be positive. Never heard this? Whats everyone think?
You need to take flywheel off and put the rocket key to the right side, take the piston all way up and put the notch about 5 o'clock, the clutch engages late and get the jump on start line (NOT sure o that clutch but may work too)
You can go to the right or left. To the right advances and left retards as I explained we'll see if retarding it like I did here works good though. Idk what you mean about the 5 o'clock though. The common thing with these is to advance it but I think they say that so much because It sounds better than retarding it. (Not saying retarding will work perfect though)
Man those v8 motors are beutiful!! Hopefully this thing will rip! Are you gunna get the top end ported? That will just be the icing on the cake. If I were you I'd use a pumper style carburetor like the Wj 71 (people use that on 50-71cc engines) to get the most power and you won't have float bowl slosh. Also that crank looks nice especially for 17 bucks!
THANKS!! The porting and major work will be done when I get speed numbers off these 'standard' upgrades. Since thats so more advance I figure I do it that way. Yea still considering my carb options... I hear the Dellorto 14/14 is a great option too!
Hi guys I just bought my son 1 of these 49cc dirt bikes it's only been ridden twice bought from new and for some reason the rear wheel has locked up . Bike will start if it's up on a stand but the rear wheel spins, engine guts off when wheel stops spinning. Any ideas on what it could be. Waiting for the shop to get back to me
i am bit stupid with these things.. :D can you help me to find it out? engine is Rabasa D50B0 I will also find something what can make me easier to find out these things... :D
Instead of sticking that screw driver in here just use an impact gun it takes it right off with out haveing to stick anything anywhere I do it on dirt bike motors all the time
I think the rocketkey is a scam since by just with that you might break the engine and 2 strokes dont really work well with more advanced timing. Though it is unique on every engine and i suggest that you get one of those adjustable ignition so you can set the timing just right
I hate to tell you this but that full circle crank is bad news now you're poor crank bearings are going to starve because the two stroke mix can't get in there to lubricate them because the full circle Crank is blocking that from happening.. . it's best to do CAM2s turbo crank mod on a stock crank You need a piston with a 12mm wrist pin for that crank to work by the way in case you haven't noticed you have to put a lot of thought into these engines to make them work right and a lot of modifications fitting and grinding all you're doing is buying junk parts from China and bolting them together your engines not going to be very good I'm sorry to tell you that... that lightened flywheel you have is bad it's better that use a stock flywheel and mod it like how Skullcam did... now you're going to have the rotating Mass of that full-circle crank and that heavy to two shoe steal clutch and that lightened flywheel isn't enough to counterbalance it... bling bling lol
Okay bro I understand your trying to help but your kind of turning me off from it calling everything I’ve been doing ‘messing up’ nothing is messed up. The engine is incomplete right now, I’m still learning about what I need to do. Thanks for watching tho
Dylon Desbiens your right it's a work in progress I'm not trying to turn you off to moding why don't you stop by pocketbikeplanet.com and join our forum that's where all the old school builders hang out we have been up to building for years :) we will help you get it all sorted out so your getting good race proven mods that work together to build gobs of power MrKitty CAM2 and EPR have all built tons of engines m.th-cam.com/video/Bv0tTfXCLQ0/w-d-xo.html
Thanks for understanding, I’m just trying to learn here like anyone else... I’ve been consistently saying this is a community build because I of course wanna hear all the little tricks and mods just like anyone else but the difference is I’m exposing myself by showing people how to do it in the videos. I’ll be talking about this in my new vid tonight! Hope you stay tuned! Thanks for any info you can give me for the build

Glad u took my arvice from a while ago lol
Rope/thick-string jammed down the plug hole to lock the engine
Love what your do bro keep up the great videos, thankyou for the paper trick between the flywheel and coil I will use that one!!!!!!!!!!
Great videos Im doing a similar build myself had a 49cc engine that was shot and it was just cheaper to buy a new one than order the parts needed. Did you ever install the electric start? Thats the one thing the new motor didn't come with, may swap over the old unit.

Any videos on how you installed the throttle cable
I have a 49 weedwacker motor on my bike could i swap it out with an enging like yours on here
Just started watching your video series who's a good supplier for these 47cc engine mods? Ebay, amazon, online store? Thanks
you can also use rope or rubber tube to stop the piston instead of the screw driver and then there's no worries of denting the piston
Yea true that, thanks
Please do a vid on the v8. That would be super cool. Also i really like these build vids. Good job
awesome. can you try and find a minimoto dirtbike. tis project would be perfect for one. my super dirt does 67 km
I too hav an exahust system. Its a tecnigas exhaust system but i will have to chop and re weld and replace the manifold with a mini moto 1.

Also could you not take all the fins off the fly wheel 2 lighting it right up sure it will add to the performance. Also you ever thort about a transmission box on.
Next time you better use a piston stop.
You dont want a screwdriver in your engine lol.
Keep on going bro nice vid
Can you recommend me a good cheap pocket bike for me I’m looking for a good beginner bike
Good job 👍
Good video bro! Subscribed!
AH Thanks :)
Give this video a LIKE for me!!
Some of you are saying retarding it like I did could damage my engine and won't be positive. Never heard this? Whats everyone think?
An actual turbo not a electric turbo a real motorcycle turbo
Unlikely for this little 2 stroker Blake
I Just Ebay search the parts like "47cc rocket key" or "47cc performance Flywheel"

take the piston all way up and put the notch about 5 o'clock, the clutch engages late and get the jump on start line (NOT sure o that clutch but may work too)

What the size of the woodroof key?
Wait how is to the left for top end??
You need quicker ignition for top end, so it has to go to the right
I am not sure i think i am gone buy one to . Are u shure ? because i dont have a clue and i dont want to do it wrong
awesome bro..... do you have a bike to stick it in
Not yet... We'll see :D
Dyaln desbiens get a m4 gp shorty exaust for the 10 dollar pocket bike build
Awesome
I did it to mine and put the stock one back
Nice
Where does that one black wire by the s spark plug wire hook up to?
That will go to the ignition on off switch when it’s on a bike
You cool bro I like your videos
Use nylon rope in the cylinder is much safer and won’t cause no damage!
Man those v8 motors are beutiful!! Hopefully this thing will rip! Are you gunna get the top end ported? That will just be the icing on the cake.

Dylon Desbiens no problem!! Yup that Dellorto is a great option
Hi guys I just bought my son 1 of these 49cc dirt bikes it's only been ridden twice bought from new and for some reason the rear wheel has locked up . Bike will start if it's up on a stand but the rear wheel spins, engine guts off when wheel stops spinning. Any ideas on what it could be. Waiting for the shop to get back to me
Clutch is stuck on by the sounds of it. Pull the clutch bell hiding off and see if it's stuck to the clutch inside.
Mine was same .I took the bell housing off and found spring had come off and was jamming clutch
Please no one ever put a screwdriver in your bore 🤦🏽♂️
is this possible to do for dirtbike/moped? if it is, how?
You would need to look it up for your engine to see what key options are out there
i am bit stupid with these things.. :D can you help me to find it out? engine is Rabasa D50B0 I will also find something what can make me easier to find out these things... :D
Instead of sticking that screw driver in here just use an impact gun it takes it right off with out haveing to stick anything anywhere I do it on dirt bike motors all the time
What are those v8's for
Chase Mitchell either skid cars or drag cars
What are you putting that engine in??
Still haven’t decided yet
O ok well keep us informed put it in a vega or something
Me kit 70 Evo 1
1:15 dont use a screw driver. Just use a rattle gun and itll come off straight away. No need to risk your piston
Yea true, thanks
Dylon Desbiens just give it a try. Sometimes small engines turn over but larger engines it works just fine
That crank is made for a 44mm piston with a 12mm pin, yours a 10mm pin, just order a new piston, not expensive
I think the rocketkey is a scam since by just with that you might break the engine and 2 strokes dont really work well with more advanced timing. Though it is unique on every engine and i suggest that you get one of those adjustable ignition so you can set the timing just right
Yea I've heard this too. When I ordered it I thought they were sure fire but now I hear the negatives. We'll see
Why do you call it a 47 49 cc it’s only a 47
The installs are the same so I want the 49cc engine guys to find the video too
Do you even know that that engine runs
What are you talking about
I hear with the head the key way don’t like it ..
buy a kit from china upgrade everything at once
I hate to tell you this but that full circle crank is bad news now you're poor crank bearings are going to starve because the two stroke mix can't get in there to lubricate them because the full circle Crank is blocking that from happening..
. it's best to do CAM2s turbo crank mod on a stock crank
You need a piston with a 12mm wrist pin for that crank to work by the way
in case you haven't noticed you have to put a lot of thought into these engines to make them work right and a lot of modifications fitting and grinding all you're doing is buying junk parts from China and bolting them together your engines not going to be very good I'm sorry to tell you that...
that lightened flywheel you have is bad it's better that use a stock flywheel and mod it like how Skullcam did...
now you're going to have the rotating Mass of that full-circle crank and that heavy to two shoe steal clutch and that lightened flywheel isn't enough to counterbalance it...
bling bling lol
