    Hi all

    Ive got a 2000ish superjet with the carbon core HT leads, basically they've all gone mushy as sh*t from the vibration and I keep dropping cylinders here and there, have shortened them up a few times which has fixed things up for a while but am running out of length now.

    Has anyone put new leads on one of these beasties? Whats the best type of lead to put on and how do you do it?

    Any help appreciated

    Cheers

    i may be incorrect, but i dont think you can replace the leads by themselves,

    you can however buy a new coil on ebay for not a whole lot of money

    what you gotta do is rip the old leads out...then pick out the remains that go into the coil tower bits....at the base of the towers are metal spikes that the leads go on......Use copper core or tinned copper core leads, this way you can strip back some of the insulation...then solder it to the metal spike on the coil..(grind away some of the plastic to give you access) .....onces soldered fill around it with hot glues or epoxy etc....

    Ive been running a coil with new leads for 3 years now and only shortened the ends once. Do what knoxie says it will save you some cash and why throw away a good coil?!?

    Knoxie, what diameter leads, and how many strands of wire? Do you just get spark plug leads?

    any good quality h/t leads will do, as long as they are resined/glued into the the coil properly you shouldn't have a problem..

    um...probably like 8mm or somethin?......I just get a couple of meters off the roll at repco.....if you want to solder it the the spikes just make sure you get a type the has a core that you can strip back and solder to...copper or whatever...

    Hey thanks Man

    Had a crack at this, wasnt too hard at all and saved some good coin! I was fairly sure there was a way to do it so thanks for the tip.

    Took it for a blast and blow me but could swear there was significantly extra power! The old spark must have been WEAK. All was well (apart from the running out of gas and drifting down the waikato river part!) :p
