Looks like I need to remove the bottom half for this new light kit to fit. My other light didn’t have the bottom half but it almost looks like someone might have cut it off.

Cut off the bottom and mounted back lights. Put some new front blinkers in. All lights, blinkers and brake lights working. Started bike briefly and lights appear to be working when it’s running.

I know the brake needs to be on but does the key also need to be on to start the engine?

Yes the keyswitch needs to be in the "ON position to start and when in the "OFF" position activates the killswitch so no-one can simply pullstart it when the key is in the "OFF" position........

Thanks! That’s what I thought. Engine is pretty trashed although I have gotten it to start.

Trying to decide whether to sell as is or put in an engine and then sell. My guess is I’ll probably get the new engine and have some fun with it first!

New 49cc engines with electric start all seem to be right around 150.

Yep they are but one thing Ill say is if i had that model chopper Id slap a Harbor freight 6.5hp engine with gov removal mod..

One things for certain is these chinese tool engines can be brought back from the brink of death alot cheaper..

Ive literally taken a 33cc stand-up scooter from out of a creek,,dried the engine ,,dosed it with silicone spray inside and outside,,cleaned itup a lil with a wire brush , cleaned-up the magnets on the flywheel then rebuilt the carb , replaced the fuellines, coil also the sparkplug put fresh fuel and it fired-up and ran pretty descently..

Then I disassembled the topend and modified it.......I think I put about $45 bux total into it to make it go from 13mph to 20mph......


Even though its my smallest CC scooter and doesnt see much action it still runs like a champ everytime I want to....LOL

This is a before pic before modifications


Scooter after mods...

I have a harbor freight engine that’s been sitting for awhile. Wouldn’t I have to use some sort of jackshaft? They confuse the daylights outta me. Plus I really want the electric start.

Re: Need a little wiring help

This may be a silly question but I ordered a new 49cc engine (10% off and free shipping) and what I didn't think of is does the number of teeth on the new sprocket have to match the number of teeth on the existing sprocket?

It looks like the new sprocket has 20 teeth. Hard for me to tell exactly how many teeth the existing one has because the chain is still attached and it's hard to get a correct count.

Will it make a difference if they are not exact?

Thanks,

Mark

If the replacement engine has 20tth its a probably for a #25 chain...

Your bike has TF-8mm chain...

The transmission sprockets interchange very easily ....

Re: Need a little wiring help

So I would have to take the sprocket off of the old engine and use it? Could I just get a different chain instead?

Re: Need a little wiring help

I think that the new engine comes with this sprocket.
Will I be able to just swap out the engine and use the existing chain?

5:1 gear ratio
20-tooth (8mm 05T) sprocket
33cc, 36cc, 43cc, 49cc, 50cc, & 52cc engines
Wide compatibility
Scooter transmission with sprocket - fits most 33cc, 36cc, 43cc, 49cc, 50cc, and 52cc Chinese-made gas scooters, go-karts, skateboards, and mini-choppers.
Brand names include Razorback, Super Razorback, Scooter X, X-Treme, Road Rat Go Karts, Skater X, Street speed, and too many to list.
