Answer Roost Boost!
I’m surprised no one mentioned these yet. Anyway heres some back round info and what the box says.
- a solid state ignition power booster that turns a standard ignition into a works ignition
- easy installation. Standard ignition wires plug right into the roost boost leads. No cutting soldering or modification necessary.
- will not overload or damage production ignition or CDI unit.
- developed on the GP tracks of Europe
Race Proven, developed and used throughout the 86 european grand prix & USA nationals & supercrosses by the worlds fasted racers
Features include.
-delivers a boost of power throughout the total RMP range
- easy bolt on installations, no modifications, plugs right into your ignition within minutes.
- will not overload or damage your ignition or CDI unit.
How it works.
The roost boost is a solid state ignition power booster that turns a standard ignition into a ‘works ignition’, like the factory works bikes use. This is done by changing the shape and duration of your ignition spark.
Its no secret that the factory riders use ‘works’ ignitions or heavily modified stock ones on their ‘production based’ works bikes. Answer Products is proud to be the first US company to offer this patented ‘works’ technology to all riders!
The roost boost was developed and tested on the European grand prix circuit since 1984, by moto-stars Jacky Vimond and Davey Strijbos. Now manufactured in the US by Answer racing, the Answer roost boost is used on the machines of the top riders like Bob Hannah, Jonny O’Mara and Alan king!
Ok this was first developed by a company called Fischer in Europe in about 84 I believe and the packet says ‘ Fischer design’ and then Answer got hold of this technology. I think these are the similar sort of thing as a ignition device made by ‘Fischer Systems’ and use to be sold by Trevor Flood Gasit Motorcycles in Australia.
I approached this with an open mind and wanted to find out more about these. I’ve heard comments saying they do nothing at all or there was no noticeable difference or they do work and you can notice an improvement, or they give a 5hp increase in power or all they do is increase the RMP by 500 or 1000rpm. I was tending to think that the people who didn’t notice a difference had other faults with their bike eg, worn engine, poor jetting etc and therefore they didn’t notice any improvement because the rest of the bike wasn’t running spot on. I thought if it did do something increasing the RPM range a bit would be about it.
US dirt bike Magazine says ‘for $52.00 you get a noticeable improvement with no drawbacks’
Dirt wheels Magazine says ‘ the roost boost is the most cost effective modification you can make on your machine!’
So I wanted to know what exactly was inside these things and if they were a universal thing that just have different colour wires for different bikes to make it a simple bolt on thing. My thinking for this is with a top end rebuild pretty much any one can do one on a 2 stroke but when it comes to electrics and wiring a lot of people can become very confused by this and don’t understand electrics. Answer knew this so they wanted to make it a simple bolt on thing so they needed to have the right colours for each bike so the average person with no knowledge of electronics could hook one up. That was just my thinking but maybe they were built different inside for each specific bike.
The roost boost fits in line between the stator and CDI unit and is connected across in parallel. So there is wires going in and then wires going out. I wanted to know what electronics could possibly be inside that could make such a positive improvement. It sounded a little too good to be true but surely they do something I thought. I connected a multi meter to see what that said. They were giving a resistance measurement and several were about the same ohm reading. I decided to pull one apart and see what’s inside. After a bit of digging I couldn’t find nothing, more digging and still nothing. I was becoming a little shocked. Eventually I got it all apart and found one single component and that’s all! All that was in side was one heavy duty ceramic resistor with 3 orange bands and a gold which means a 33 K ohm resistor. That’s all it was!. I was surprised.
This one resistor was connected in parallel across the wires going from the stator to the CDI. So basically its in parallel to either the primary or pulsar coil or both, I haven’t worked that out yet. So how could this possibly give an increase in power? All this works technology is, is just simple 50cent resistor!. very simple and not complicated at all! My thinking is this- in theory when you put more windings on a light coil you get a more resistance and more power and can run a brighter globe. So if since this resistor is connected in parallel to one or both the coils on the stator plate this does a similar thing and increases voltage and this then goes into the CDI unit and then makes makes more power and maybe somehow increases the RPM range and giving a HP increase. I don’t know. Whats other peoples thoughts on this? Maybe there is some one who has some knowledge on ignition systems and can explain exactly how these are ment to work.
ive got one for a late 80's YZ 490, maybe someone can borrow it and do a test report and report back with what they find out!
