KIT DETAILS -
The kits includes everything you need to
complete the conversion, including the spark plugs of course. The spark
plugs are over-the-counter NGK automotive spark plugs.
The wires are 8 mm Taylor Spiro Wound racing wires custom manufactured for me by
Taylor Cable Products. With regards to RFI, the Taylor Spiro Wound wires are
designed to eliminate RFI. I have experienced no noise whatsoever in my
personal Yak 52. Here's how the Spiro Pro wires eliminate RFI as explained by a
Taylor engineer. "Electronic filtering is possible due to two types of
components. They are capacitors and inductors. Capacitors like high frequency,
and will allow it to pass, while they hate low frequency, and will reject it.
Inductors like low frequency, and will allow it to pass, while they hate high
frequency, and will reject it. The Spiro Pro wires are constructed in such a
way that they have a certain ratio of capacitance, and inductance. This causes
the wires to be a high impedance to high frequency, (which is RFI). They will
allow the D.C. component of the firing signal to pass through while blocking the
A.C. component, (the part that causes RFI). The composition of the core, the
thickness of the core, the size of the conductor, the permeability of the core,
the number of turns per inch, etc., all have a direct relationship on the
suppression factor of the wire."
The following bullets are taken directly from the Taylor web
Spiro-Pro wires provide more fire power to the spark plugs than OEM resistor
core wires and up to 10 times less resistance than standard resistor core wires
- Spiro-Pro eliminates radio frequency interference (RFI)
and is a must when using a multi-spark
discharge ignition system, electronic ignitions, and on board computer
- Spiro-Pro’s two layers of 100% pure silicone makes
it the highest temperature rated wire on the market (600º F) without the need for additional sleeving
- Features Taylor Cable’s EXCLUSIVE low profile, 100%
silicone PRO BOOT® with grips and vibration proof double spring locking spark plug terminals
The wires are cut precisely to length for
each and every cylinder for both mags. Since 8mm wires are slightly larger than
the holes in the mag cap, the kit is supplied with a drill bit which is used to
drill the magneto distributor cap holes to the proper size. Since the magneto
distributor cap material is relatively soft, drilling the cap is quite easy.
The front plug wires are marked "1" through "9" and each front spark plug wire
has a red band on it to signify the front plug wires. The rear spark plug wire
set does not have a red band on each wire and each wire is also marked "1"
The kit includes a sufficient number of tie wraps to dress out the wires to
hold the rubber hose pieces in place through the baffling (standard kit; not
needed with deluxe kit with new baffle grommets). The instructions are
precise and include color photos of the installation which are provided in
the kit on a CD.
On the standard kit, to facilitate the installation of the 8mm wires into the magneto through the front cover, one
must grind out a small amount of metal inside the hole of the front cover of the mag. The 8 mm wires (vs. 5 mm standard Russian wire) won't quite go through the
cover otherwise. It's very easy to do with a Dremel tool, die grinder or
something similar. The material that is removed inside the hole of the front
cover is excess metal and has no impact whatsoever on the strength and rigidity
of the front cover. The wires fit though this hole very snugly.
Please note, with the deluxe kit, this procedure is not required since the new
magneto front cover plates have individual holes for each 8mm wire.
Removing the Russian wiring harness takes time. There are 4 metal tabs on the
ring that bolts to the case. The 11 mm nuts holding the ring tabs are removed
with a 1/4 drive 11 mm socket and extension. I have found that a flex or swivel
11 mm socket works best. The ring splits in half at the top and the large
braided shield that goes from the ring to the mag cover is also completely
eliminated. Once the Russian wiring harness is removed, the reassembly is quite
nice. You'll be amazed how much more room you have without the Russian wiring
harness in place.
You have the choice of reusing the metal clamps that hold the original, braided
spark plug wires or tie wrapping the wires to the intake tube using the supplied
rubber hose. Either way works. Since the intake tubes are "cool" compared to
the exhaust temperature, there is no problem with heat concerning the wires when
they are affixed to the intake tube using the rubber hose and tie wrap.
After installation, on my first attempt to start the engine, I BARELY touched
the start button and the engine fired up instantly. The best it EVER has. I
couldn't believe it! The idle is really smooth, which I attribute to a hotter
spark. The mag drop was 2% or less. Again, better than it ever has
been. It accelerates better and just feels like it has more power.
I hope this answers most of your questions. In my mind, it's the best
conversion for these engines and the cost is less the the cost of one set of
Russian or Chinese spark plugs. If you have additional questions, please
either email me or call me at
334-546-8182 (mobile). I'll be happy to answer any
questions you may have.
