2T Power capabillities

Hi guys i don't want to sound like a yooth but as i am 16 there is a limit on peak engine power (3.5kwh ?)

and i was just wondering as my JSM 50 is a two stroke i know it can gain a lot more power

(Deristrictions, Exhausts,Reeds even bigger carbs) just wondering what the law says about tuning a 50 when im 17.

im a apprentice mechanic atm so buying a 125 when im 17 just dosent seem logical to me when i have a perfect bike now and i have limited funds already

its a am6 Minarelli engine and its a 2011 model

so i can legally tune the 50cc up to 11KW ?

Yes, when you’re 17.

Although you’d have to declare all mods to your insurance which would most likely send it sky high.

What about swapping the engine for a 125cc?

Get a Motocross or enduro motor in there and it will fly!!

Sound awesome too.

I was thinking of doing that however i just cant find a 125 two stroke also if i put a sprocket with one more tooth on the front what would that do ?

so i can legally tune the 50cc up to 11KW ?

11Kw is about 14hp,good luck with that in a road going 50cc.

My RGV250 supposed to make about 60hp so a fifth of that is 12hp.

The RGV can only achieve this with massive exh ports and 2 stage power valves,if it didnt have these it would be unrideable on the road,powerband is only about 2500rpm as it is.

By all means have a go at tuning it,I know I did when a yoof, but dont expect high power,rideability and reliability to go hand in hand.

if i put a sprocket with one more tooth on the front what would that do ?

It will Make it accelerate slower

Go 1 down on the front will make it a little crisper..........but this is a 50cc road bike so you can throw as much money at it as you like but it wont make it the same as a 100-125cc

There's no substitute for CCs !

There's no substitute for CCs !

That’s my philosophy with cars. Glad to see it also applies to bikes.

I'm 16 as well and PLEASE listen to this advice

I bought a Yamaha rz50 didn't start with problems but had one and its taken months to fix

then I bought a Chinese 50cc (2015 wk wasp 50cc 2 stroke) for £650 in the meanwhile and out of the 3 50ccs it was the best, smooth and topped out at 45mph, very good for a 50cc bike. it always started and acceleration was good.

I crashed it in the wet.... plastics were hard to find so I bought an Italian 'sport' 50cc, a gilera dna 50. and even though it works, is rideable and has a higher top speed, it is much harder to use and frequent issues as well as it being generally hard to use for town riding with transmission troubles and small powerband, I miss the old Chinese 50cc that was way more comfortable, cheaper to run and use and easier to ride.

still waitin on the rz50 to be fixed.

listen to the old guys, I didn't. buy a 2 stroke newish bike that's already been derestricted (like I did) and its likely to serve you well as it served me well.

DONT try and soup up a 50cc to 125 capabilities, sell the 50cc when you turn 17 and buy a cheap 125, I haven't got to that stage yet so I cant offer advice but id assume its a similar story to my experience with the 50ccs, which is, souped up 2 strokes aren't reliable and aren't easy to ride, buy a cg or whatever for cheap and have fun with it

also, don't worry about the laws, just stick to 50 at 16 and 125 at 17, and know you will spend a lot of money making an unreliable bike.

because iv been at the point where I don't have wheels and had to take the bus, or it wasn't working properly so it was an emabrrasing stop at the side of the road, and in all those instances iv wished that I hadn't hit the brakes so hard in the wet after a frustrating after school detention and took more care of my 'crappy Chinese scooter'.
