you really need to shorten the clutch springs, it runs like shit.

en I think a whet Nos system? Dry is rubbish.

what does your moped sound like? i removed most of the insulation from the silencer... its really really loud.

how much do i shorten the clutch springs?

How do i know if the NOS i bought is dry or wet?

what trademark and kind of kit do you have ?

have any pictures or something like this in the kit:




friend om mines wet inject system...

2.3 pounds bottle , BIGASS< does not even fit in seat of a scooter.

also, do you know of any videos that i can view, of a moped with shorter clutch springs... how much of an improvement is there?

Here is the NOS i bought:

please you can edit your post, dont double post.

you bougt a dry kit, probably you wil blow up the cilinder the first time.

And shortenings the clutch springs, depens on what you like. The first one is for pulling power, more revs when turning the gas. The second one is for shifting moment. Begin with 1 cm / 0.5 inch. Then test. Go on untill you are satisfied

Indeed,

A wet system is better for moped/scooter use.
I know some people who also have wet systems and it works good. Very good.

A tip: Don't get to exited to test it, first make sure everything is well prepared.

so, i should not install this NOS system? can i actually blow up my cylinder head? Can i still use this NOS that i bought?

Where can I get a wet NOS system that wont cost too much?

you cant get a cheap wet system, here in holland you can buy them for 600 euros, 800 dollars.

thats way more then i would want to spend on this moped. Can i still use the dry nos i bought? should i even attempt? I dont want to screw up my moped.

I wouldn't risk it.

How much did it cost?

$50 US

well you can try it with a vlave, then you sometimes an push a button for a 4 seconds boost. Mix oil/benzin 1 : 40 and you wont blow it up.

Hellracer_89, I dont understand what you mean. Where would i put a valve? What was that about push a button for a 4 second boost? i dont understand what you mean.

He means push the Nos button for 4 seconds and then release the button.
Short periods of Nos.

If you'll do too much Nos in 1 time, your cilinder gets way too hot.

What gearing does it have? It sounds like its bogged down. I think the problem with dry Nos is that when you hit it, it will cause your motor to run lean.

place the N20 cil on your moped, and mount a valve between the N20 cil and your carb. then you can regulate the nos, not only a 40 second boost witch blows up your engine.

so if i run rich would it counter it?

I wasnt planning on using NOS often... just for a boost in order to accelerate from a stand still.

Do i attach the NOS tube to the end of my K&N filter? What kind of valve do you have in mind Hellracer_89?

Saabsonettguy, what do you mean "what gearing does it have"?

You guys seem to know a whole lot more about this stuff then anyone here in Canada, or the USA... the other moped forums seem to be full of clueless people. I really appreciate all the help.

What sprockets does it have? Stock 26/22? Or did you change the gear ratio? You could put a big main jet in the carb but then it might be too rich when your not using the nos. You should email harold on mopedarmy he had NOS on his puch maxi.
