NOS

[Whosthedaddy]

I was initially thinking of upgearing the monkey (by a bigger front and smaller rear) to give it a little more top end grunt, but was worried about the comprimise in acceleration, which for a small bike aint half bad

Seen some NOS systems for a few quid that may add a little va-va-voom

eBay

There are ones at half this price that dont include the filter.

So, would they be any good for short blasts and for hooning through traffic?

The 'instructions' are supposidly simple and can be fitted in minutes, but where would the end of the tubing go? The carbs, but where?

As its only a small cannister, would the detremental effects be lesser than a full system on a much larger bike?

The thing that confuses me the most, is how the hell do you hold the bottle and the bars at the same time and still have control of the bike when the button is pressed

I've never messed with one of those kits so i'm open minded. But i can't see them working too well. An engine gobbles nitrous at a crazy rate and although those kits are designed for very small power increase on very small engines i can't see those canisters lasting more than 2-3s a pop.

Considering those bottles are unlikely to hold 800psi and the system is dry i suspect it is nothing more than compressed air or some other cheap oxide which while it would still work on a small engine like that, it isn't nitrous.

Still for £35 it's worth a shot and should be a laugh.

Sorry, I'm no help on this subject - I'm just hear to ask that if you do decide to go ahead, please film it (:

TBH, I dont think that Youtube will accept snuff films

I seems that the bottles will last for 20-30 seconds depending on how long you hold the trigger, with 10 bottles for less than a fiver, could be worth a laugh.

Go for it, i'd love to see the vid

My mate used to have an O2 feed into the carb on his C50. Gave a decent power increase.

Doubt that's proper N2O.

Haha, good idea that, mini-moto NOS. What ever next?

Anyway to get any meaningful power increase you'll need a larger volume of nitrous, and extra fuel to go with. I suspect downgearing would be a better mod.

They look like the identical canisters to those quick tyre pump up kits you can buy.I reckon thats just oxygen.

I knew i had seen those before.They are compressed air canisters for air rifle guns

They are real N2O, the canisters are identical looking to powerlets for air rifles, but they are intended for use with whipped cream dispensers. You will be able to decide amount of boost/length of time by jetting the end of the line if you so wish. All I would worry about with a kit like this is that since you are injecting N2O with no additional fuel, all the time you are injecting your "NOS" you will be running mega lean.

From what I've heard they don't work very well (mostly make the bike bog down) - also the advert suggests they don't know what they're talking about.

There's some pages somewhere for guidelines to make DIY N2O kits; worth a google.

There's plenty of tuning parts and knowledge around for 'standard' tuning of those engines; I'd go down that route myself (or just get a proper bike ).

I would absolutely love to see the video with this beauty in action.

i have a nos kit on my racing scooter
and it DOES work trust me !

[Resurrection]

[Jamie S]

nah 35 mph then goes up to 45 with the nos on
this is the same as mine. so not a bad speed really.

[Resurrection]

So how have you clocked this speed?

I kinda doubt it especially as you said your 19 stone

LMFAO

i had 1 of them scooters cheep fake nasty thing!
i but a bb kit on it and bigger carb and it wouldnt go any faster then 30mph! i did this against my missis pug 106. im 5'11. 13 stone!
even propper GO-PED dont go fast than 35!

however back to the NOS it does work! i had lots of mini motos in the past (dirt) and made 1 of those kits! my mini moto did 45 against the missis car! with the nos i never tryed but i reckon it did 60mph! didnt last long though! 4 shots and 1 all mighty bang!!!!

res mine has a spedo and indecators on it

[djneu-trix]

how acurate you reckon thats gunna be

they say when you buy it that they can go to speeds of 50mph LMAO

well its not a standard part, Its a honda one off a monkey bike.
They recond 40 mph when i bought it , and there is no way it would have done that, i have done a few things to get it up to 45 but it really strains the engine (i dont know how many revs but its screaming the balls off it !) so it dont like going any faster than 20 on it

That's the beasty I got, from here

Could just go the whole hog...

£2k would go nicely towards a proper bike or the SRAD I've wanted for ages now

Dont really know much about performance parts to be honest, cams just control the inlet valves for better fuel / air / spark combos dont the, hence the slight increase in power?

[garth]

Essentially yes. Gave mine 2Tish power characteristics when compared to standard. However the ss50 has self advancing ignition whereas the bog standard c50/70 is static, which helps.
