sorry no ,thats the only sliders that i can't get from my supplier
5gr rollers yes.
however you can mix sliders like a set of 6gr & 4gr , 1 of each in
each set of ramps it will average to 5gr
a bigger jet is necessary for your pipe ,also a cooler plug would be advisable .
stock is a 7 so with NKG plugs you would want a 8 . if you have a 70cc cylinder kit
use a 9.
NKG plugs are backwards to most plugs, usually a 7 plug is hotter than a 6.
but NKG get cooler the bigger the number....
in case you didn't know how a expansion pipe works check this out
http://en.wikipedia.org/wiki/Expansion_chamber basically the reverse cone pushes (scavenges) the fuel rich air (sonic pressure) back
in the cylinder super charging the mixture giving you more power and upping your rpms.
