Well I traded a laptop for this piece of junk. Just needs a back wheel and engine and simple parts I can work on getting. but I kinda wanna rip it in the snow once. Oh I forgot it's also getting a big bore kit. First off I basically got it for free, free laptop = free pit bike? Anyway here's my plans...

Re assemble what I have.
Pull apart and paint
Get rear end engine and new front tire
Re assemble
And rip! :auto::bannana:
Also if I get everything cheap, pitbikes sell for 300$ where I live lol!
It came with a drill and cro bar for free with the parts box. the drill was croded so I cleaned it and it works in reverse full speed, but I need to clean the forward prongs for it to work again. Im going to use it to build a mini lathe for like small wood and plastic bits, i can also use it to cut bolts and make bushings which would be awesome. If it doesnt rain im going to start assembling the pit bike . However if it does rain im working on my mini lathe

It's funny that you say it's getting a big bore kit. I'm not even sure what size engine it's supposed to have.

If you can fab up a mounting plate, one of these would work,

49cc 2 stroke bumped to 53cc with a big bore kit already on it. Advertesed 2.6hp @ 7000rpm, and 2 lb.ft. @ 5500rpm. Also, since it's a 49cc engine with a big bore kit, you don't need a motorcycle endorsement (at least not where I live).

With one of these

I got one of the base engines and the pitbike it came off of from my uncle for free. It's the engine I'm going to use on the scooter conversion.

Here's a better picture also it looks like it has mounts for a 110cc or 125 which are easy to get and a big bore kit is 60-70$ on ebay

I'd leave it that size. Should have enough power (50cc four stroke bikes move pretty well). But a transmission is a good idea.

that bike looks like it had a 50cc or a 70cc on it originally (110s and 125s are taller bikes, they can go around 50mph stock)

a 125 should be more thne enough for this bike (the 150s are a longer motor, so you might be hitting the front wheel)

looks like a good project, should be a blast!

ohh, its one of those lol

it was probably a electric version, you can swap a pocket bike engine.(get the 50$ ones on ebay, ive had good luck with those ones)

just need to drill some holes and it should just bolt into place.

Looks like it'd fit, with some modifying. But please, take two seconds and turn your phone sideways. It'd save us all from some doctors bills.

Yup, it does look like junk, you will be spending more than $300 to get this back to complete. Also, you are 1,000 posts in and still can't get a picture correctly oriented?? :roflol:

I know, my neck's thinking about filing a complaint. But hey, I've got to give you some credit. After all, you managed to get one of the four pics oriented correctly. :thumbsup:

for the razer, your best bet is a pocket bike motor, it should bolt right on where the eletric motor went. going to cost you about 100$ all said and done (motor + throttle + chain and sprocket)

for the pit bike, id use the forks you mentioned on trying on the razer (they wont fit without serious modification) id use the flat head on that bike (would be a sweet pit bike!)

agian, just my 2c
looks like youve got a lot on your hands, cant wait to see what they turn out like!

The razor is more of a side build because it might be fun if i run into a problem i cant fix ill probably give up on it. but i think a tiny pit bike with a big engine will be fun the otherone im slowly collecting parts for it. Ill most likely put the 49cc with the big bore on the big pit bike also im building these on my normal 16yo budget of nothing so im using what i have
