Replacing HT leads

[Spike16]

Hi i wana fit some new performance HT leads to my race bike, does anyone know were I can get the connector to crimp on to the end were the plug attaches, and the plastic ends that attach to the coil?

[Sligeach]

did GF not offer some sort of service for making HT leads?

It's not terribly hard to convert over to Coil on Stick to get rid of the HT leads all together. Plus it's lighter than the stock coils and leads.

Coil on stick sounds good.. how do you do that? Can it be used on road?

Grab 4 05-08 CBR600RR stick coils. Buy a 600RR coil sub harnes off Ebay for the connector.

Now wire 2 coils in series and connect them back to the appropriate tap for each set of cylinders. Cut 4 - 3/4 I.D. pieces of tubing about a 1" long. Slide them over the coils. Take the threaded adapters for the HT leads off the top of the plugs.

Drop on your stick coils and ride happily. The Dyna coils are pricey and don't make a huge difference to the bike. They are just hard to mount.

Postive wire of coil 1 connects back to the appropriate wire of CDI.Negative wire of coil 1 connects to positive wire of coil 2. Negative wire of coil 2 connects to appropriate wire to CDI.

2 - 1.5 Ohm coils wire in series will present the 3.0 Ohms the CDI wants to see. You'll have no problem on the street and you'll have access to replacement coils for years to come fairly cheaply.

Excuse my ignorance, are 'performance' HT leads designed to give a slightly stronger spark? Is this all?

Thats about the long and short of it.

I always go for 'mid price' leads unless they are reallly long then i might get something more expensive.

As for the stick coils.. if your fitting them to the NC24 you can just wire one up to each coil, you'll need to put a 2Ω 5w wire wound resistor on the positivie side of each coil to avoid burning the cdi out as the cbr coils are lower resistance. :)

err whats a stick coil?

[venom51]

That'd be those things that come on modern bikes to fire the spark plugs.

Instead of separate coils and HT leads/caps you have a stick coil. It sits in the spark plug hole with the plug in the business end. Kinda like an plug cap and coil rolled into one. They're neat, but can be difficult on some cramped engines when you want to remove em as they're long awkward rigid bastards and then plastic insulation is prone to splitting causing the volts to leak.
