I have a Peugeot vclic 50cc which is just the BT49QT-9, but just rebranded by Peugeot.
I currently get around 40mph on the flat, but my acceleration isn't very good.
I think it has a few restrictions still left on it because 40 is the max it will go, even on downhill.
For the low acceleration issue, I was thinking of new rollers... is 4.5g the best weight?
The lower end is mainly what I want to improve at the moment, is there anything else apart from rollers that'll get it going a bit faster?

I am sorry to be the bearer of bad news but anything near a real 40 MPH on a 50 cc 4t is pretty good. In fact, some states restrict 50 cc scoot without tags to 25 or 30 MPH. The bottom line is trying to get more than 40 MPH out of an air cooled 50 cc 4t with any real reliability is a very steep uphill effort. Frankly, ride it a bit and save your money and upgrade to a 250. Skip the 150. It is at best a 50mph scoot. A 2t is a lot different.
It is simple: To get enough power out of a small (50 to 150) 4t to overcome the drag of the high friction squeeze belt drive system and limited cooling of a covered air cooled and small wheels is asking a lot. 90CC Honda motorcyles with 4 valve heads relatively well cooled running leaded gas with an efficient 4 speed transmission/chain drive built with all the precision of high end Japanese machine work pretty much ran out of go at around 55-60 with me in my 135 lb days. And despite all the progress we really have not learned much about making a gas engine develop power in the last 50 years.
Good luck and enjoy what you got. I frankly think the best solution is to get a bigger scoot not to try to modify this one. Pay attention for a few months before yo think you know more than the factory.

A 50cc with all the bells and whistles big bore kit and all will be hard pressed to reach 50 real mph. You can change the gears and put the biggest motor available for it and it will usually top out around 45 plus or minus a few mphs. I have a highly modded 150 its a different beast its highway capable now but with all the mods I could of got a 250cc cheaper, but modding is most of the fun for me with these little motors.

How about getting the acceleration up? It's quite slow off of the line but once it gets going it's quite fast.

Try lighter slider weights first, if that's not enough time for a big bore kit.  |
