49cc for daily Commute.

[09zufar]

Hello everyone.

I currently have a New Way Grido chinese scooter and i was wondering if it's possible to make it more powerful for long distance rides by keeping it a 49cc.

I've been riding for 4 months now and there are situations where i feel unsafe due to the lack of climbing power.

DETAILED SPECS :

Make & Model : New Way Grido
Engine : LJ1PE40QMB 2T 49cc
Top Speed (GPS VERIFIED) : 72 KM/H
Uphill Speed : 40-45 KM/H

My goal is to cruise at around 80 KM/H without any difficulties with a good amount of torque to keep it constant and a little more power in reserve if i want to overtake.

I was going to buy a 19mm super flow carburetor tommorow then i thought i should ask you guys first.

How important is a hi-speed variator in achieving the mentioned speed ?. Is my stock variator not enough if given the right amount of power from the engine?.

I would upgrade your CVT first before anything, and if you still need more I would do an exhaust and upjet the stock carb.

Okay.

I will buy the Malossi Multivar as it is the only model they have here.

and for the upjet, i need to increase only the main jet size?

I'll do these 2 things and maybe post a top speed/acceleration video.

The biggest gain for least amount of money is a big bore kit. You could still use your stock exhaust and carb if you wanted. Just change the jetting.
I'm guessing at 72kmh if that's on a level road. Your exhaust is not restricted.
I variator will help with keeping the revs more constant. And hill climbing. But won't add much to the top speed.
An exhaust is the easy option for more power. A good exhaust will give a big increase in top end power.

I agree with Aeroxbud bang for buck a bbk is your best bet. Jets are cheap and if the needle on the carb is adjustable it’s a little more fuel at partial throttle. It’ll give you a little more top speed and get up to speed much faster which in my opinion is more important for commuting. If you need a few more MPH, a good exhaust like a Malossi Wild Lion will get you in the 80 kph range depending on what the final drive ratio on your scoot is.

Thanks everyone.
Where i live in Mauritius, 50cc's don't come with restrictions.

I will get a 70cc kit, new variator and if possible a new carb or upjet my stock one.

I will post the acceleration video after im done with it.

Quick Update.

I ordered bigger main jets, high speed variator, and cold air intake.

Already received the jets. Waiting for the other parts.

I wanted to keep it a 50cc. Will update once i install these and do a top speed test.

If it still won't go 80km/h easily then ill go for the 70cc bbk.
