2 stroke chinese spark plug+wires

Most people assume that because a spark is involved there must be a substantial current too,this is quite erroneous.The curents involved are only a fraction of a milliAmpere ! and resistance plug wire if correctly built works just as well as metallic wire,but cuts RF (radio frequency) noise greatly,as do resistor plugs.The problems occur because of poor connections to the coil or the plug,this causes internal arching which exacerbates the problem.Current leakage due to poor insulation is a major cause of ignition failure esp.under wet conditions with a marginal coil or CDI unit.HT engines in particular are plagued by ignition failures due to marginal design and shoddy constuction.

Plug boot

Metal socked of boot pulled out. but will stay on and work, but good bump will make boot jump off plug. How can i fix. glue

The very same thing happened to me, dont waste your time trying to fix this piece of junk. A motorcycle parts shop probably can supply you a spark plug boot and some better wire too.
 
How about the length vs resistance ?, I'm trying to tuck the CDI out of the way of any water. Can I get away with 1' or 1 1/2'


on one of my bikes, I have my c.d.i. hidden under the engine down my the cranks, with about a 12-13 inch long accell 7 mm superstock spark plug wire. Length isn't an issue with a GOOD plug wire.

on my other bike i have the same plug wire, but it's about 6-8 inches long. the cdi is down low on the seat post tube.

I had a spare boot so removed old one and screwed it on the end of cdi wire.
Now if i had a new wire would it screw on to the CDI the same way as the boot does?.
What was your fix.

Yes the two ends are to screw. I got my "boot" from a Honda CG 125 but I doubt they have this motorcycle there in U.S.

you can use ANY automotive spark plug wire and boot....it doesn't have to be for a motorcycle.
the only exception would be a boot made for a chrysler hemi (old style) because they had big ceramic boots on then because the spark plugs are down inside the valve covers.
you can go to autozone or wherever and buy a set of plug wires for a 4 cylinder car engine for about $10.00.
this would give you enough spark plug wire to make several for a m.b.
one from a lawnmower would work too, but it may not have the length that you want.
The thing about using automotive spark plug wires is the length.
you can make them as long or as short as you want.
 
20kv insulated neon sign cable also woRKs well...available in uber hot colours too ;)

auto leads are invariably "resistive", so use a standard (non resistor) boot... and plug (b6hs, not br6hs). possibly easier to find unless you have access to neon signs ;) on this note, be careful with what boot you get. the ones with resistors do fail and need the resistor replaced occasionally.

or dont even :) all it does is stop radio interference and so far, i havent seen anyone with a doof doof box on their pushie!

a wire is a wire. its the insulation that counts here.

currently my boot is from a brushcutter. little rubber thing and the "clip" inside it is just stabbed through the wire :) only one that hasnt vibrated apart within two weeks!
