Making my 50cc accelerate faster

[iainsalter]

i just bought a yamaha BW SP-Y 50cc scooter. it has some sort of sports exhaust fitted which makes the bike go alot faster. im interested in making it accelerate faster for fun. could anyone tell me what i should buy which i could get fitted by a garage?[color=black][/color][size=18][/size] :D :D

this realy depends on how much money you are wanting to spend, i would recomend a polini variator which are around £50. if you are looking to spend less then just get race rollers about £11 and cluch springs about £7...

All that was said above wont make the bike much quicker off the mark. If you want best 'bang for the buck' then wack a basic 70kit on such as the polini iron for around £70. The kit is good and provides most 'bottom' end punch so wheelie addicts love them,so i imagine there good off the mark. You have to spend to get gains im afraid..

[nrg-mental]

dont put a 70 kit on it unless you wanna blow your bottom end...

if you just want it to accelerate faster put different rollers in the variator,
You will probably need to have a shop do this for you as you need a windy gun to remove the lock nut.
If you are thinking about a new exhaust its not that simple, some require you to de restrict your bit but some if there nice will give you all the things you need, rollers, and jet.
As you have an exhaust kit already fitted you could try the first option, rollers.

there fairly cheep at around £16

on a different note I believe the fastest accelerating 50 at the moment is the ludix blaster, Doesn't mean its the fastest, just gets up to 30 the fastest, or so I've been told

red powerbands are the best for acceleration and wheelies
go down to your local bike shop and ask them for one. usualy about £5

For goodness sake..enough with the powerband blags. Just because you put 'powerband' in a post it doesnt enter you into a special group or anything ..so i guess you can stop now? Thanks.

I fort black was fastest as its knightrider speed?
Anyways
Exhaust.
Jets.
Rollers
Higher octane fuel
Iridium plugs.

Although some of those could damge your bike

Wrong,
Next time you get some time
insted of putting in 95 octane fuel in sainsburys
go to shell and put in some Vpower which is like 101 octane.
My bike goes like stink, and accelerates soo much better.
And the plug issue, im pretty sure better plugs do make a good difference.

O right,
felt faster and more responsive to me,
deffo works for turbo cars as thats what all speed trials do along with their hks drag fuel

and for reference
V-Power has a rating of 99 RON,
From wiki
cheers

shell v power makes a hell of a difference to my bike.
so much crisper and more responsive.
but i dont think it makes it any faster.
spose it would help if my speedo was working

As i've said before it won't make any difference. It's all in your imagination because the adverts say it's better.

It is only better in high compression engines as the fuel egnites under a higher compression.

If 95 RON is used in high compression engines detonation can occur.

Using any higher than 95 RON in a 50cc will probably make the bike slower as it is harder to ignite.

KEErist there's some utter bollocks about octane posted in here.

Using a higher octane fuel without any other modifications to take advantage of the higher octane does 2 things

Makes the engine harder to start owing to the fuel being less volatile

Makes the engine run a bit smoother owing to the fuel being less volatile

& a 3rd thing if you run leaded Avgas etc:
Makes it smell nice & turns the inside of the exhaust white.

[Joeb46]

trust me it makes a difference, either that or the the other fuel i buy is shite

i got a yamaha jog rr 50cc, its LC and only ways 79 kg dry weight, it went 43 mph when restricted.

i would say buy a carbon fiber reed box, go for some 3.5g rollers or maybe 3g if u want really fast aceleracion but not so good top end.
also buy 3 new clutch spings and a new tork spring.
a cavalier race belt, might be more but will last longer so all good.
um a 5mm fuel pipe, also u could get a bigger jet i incrusted mine by 20 sizes for the exhausted alone.

as u have a yamaha i would only recommend molosi part to you, get a molosi variator (hard to find but well worth the trouble) could go for a half or a quarter throttle if u really wana fly like a mad man, um could always go down the rought of making it lighter but thats allot of money.
