Are these easy to install and use?

[Hick727]

Alright so Im building a homemade go kart and I was thinking about putting nitrous in it. I found these http://cgi.ebay.com/ws/eBayISAPI.dl...=380146509306&ff4=263602_263622#ht_3101wt_735

Are they good? Are they easy to install cause I dont wanna screw up and have the thing explode on me

How good is your engine/mechanical knowledge? It looks (is) "easy to install and use". What may not be apparent here is that it'll mess with your air/fuel ratio, and cause an excessively lean mix, which could result in scattering engine parts. You'd have to figure out how to feed it an extra, appropriate amount of fuel when you hit the switch. Your governor would have to be bypassed to get the extra RPM, and depending on the age and condition of your engine, you could end up scattering engine parts anyhow. This is assuming the kit's worth a darn to begin with.
Personally, I think it looks cheap and gimmicky, and I've always believed that anything that sounds too good to be true, likely is.

Not worth it IMO.

Good way to melt a piston.
