Razor MX350 Engine Swap! Electric to Gas! 

What engine did u put it on where did u find it bc I'm looking to do one of these builds

Hi uncle mark, Can’t wait to come see you guys.

i saw this vid and i had a razor mx350 of my own and gas swapped it and it went 34 miles an hour.

This is a awesome build. Two strokes are always a good time. I took a Razor MX and put a predator 212cc motor on it. Man does it fly, it is a little scary running it wide open lol.

Hey man, do you know if these support a swingarm extansion? I have a variation of this model and it doesnt have a rear shock like the older models do. I know the swingarm extension mod is fully compatible with the ones that have a rear shock but im asking for mine since yes... i know theyre meant for kids around the usual age of 8-12 or maybe 13 but they support up to 140 pounds in weight or atleast my model does from what i know. I myself weight 135 sometimes my weight goes up to 137. Its rarely gone up to 140 but not any higher. Im 21 by the way. And like i said i know theyre meant for youth but as i mentioned it supports my weight and ive also seen some people on youtube mod these models and some seem to be the same age as me. Others seem to be older. Either way if you need to know, the reason i want to do the extension mod is because i want to do a gas conversion aswell yet i want to install a somewhat big motor also the model of my mx350 has a steel tube where you placed your motor in. It might be removeable but im not so sure about removing it.. and well the extension is so i can have a good enough soace for bith the gas motor and maybe put a small backup battery. I know it seems wierd but my dad has done these things with old bikes turning them to motorized dirt trikes having both gas motor and a small battery so i can hook up both a led as a head light and a small tail light in the rear. I dont know how well to explain it but i hope you understand what i mean. Either way ive been typing to much at this point jaja but yeah. If it is that you know if its modable then please let me know i just wanna be sure. If its not possible then i can still just add a small motor but like i said illd rather prefer a motor aswell as a small battery with it. Thanks in advance

Thank you this was really helpful! Could you possibly show me how you mounted the new sprocket if you did?

This is awesome!!! I have one that’s already stripped to the frame I just need to install the engine! I was wondering did u cut the center support bar?

Hello, I have a razor mx400 and I want to convert into gas but I don’t know how. Can you please do a step by step tutorial pleaseeeee!

Thank you for this vid. A family down the street from me threw out both an MX350 and a Mod Bella. What a waste, I grabbed both out the trash and am going to do something fun with them. Seeing your build has given me lot of ideas.

Is there a way to flip the freewheel on the wheel so the sprocket can spin the other way? I’m trying to put a 50 cc engine in it and I have the same problem

Do you need a battery connected to it to get spark or can you just pull start it without a battery

How they put the wod

Good idea. An it's good to know I'll use a ten speed bike Road Rear Derailleurs to take up the chain slack.

So you put the wire on the sprocket to make it stay

Hey! I recently did one of these exact builds, and to be quite honest, you actually helped me a lot! And I just had one question, will it hurt the engine to run it with no pipe? I’ve been trying to find an answer to this for a while, but came up short. Thank you!

do a vid about it 1 more time and JUST how u did it

I’m doing build right know

What chain did you use?

How much did this cost at the end of the day? I just looked at a Suzuki 50cc dirt bike for my 5 yr old. It was $1K. After all this work, and these parts, seems you could just have the real thing, and far better. Safer too.

what size sprocket are you running? Do they make a quieter muffler?

How did you do the wiring please post a video or something please lol

Wondering if u shorten the chain it will help keep chain tight n solve the loose chain problem.

That's badass!

Bro you are a genius

What kind of oil do you use

How did you Mount for 2 x 4 to the frame

What type of bolts did you use to mount it?

Did you move the sprocket from right side to Left ? I have an electric mini bike and want to convert it to gas but on mine sprocket was on the other side

can you put a faster motor on it?

Where u buy clutch sprocket

Stupid question why didn't you not put the motor where the electric motor was

Where did you find a chain that long? i have been looking all over and coming up empty...

She got more balls then me to ride with no brakes

I started at four let him ride
