HOW MUCH IS THIS REV LIMITER GOING TO COST ME?

$80.00 +gst if you have a DIGITAL 'K' Ignition (Key Start). This unit has been subsidised by Remo Racing as this would normally cost $260.00.

 


I HAVE AN OLD ENGINE WITH THE GREEN AND RED BUTTON (BLACK BOX) HOW MUCH IS IT GOING TO COST ME?

$590.00 +gst. This includes a complete ignition system (key start) stator, rotor, coil, wiring loom, barrel and key, brains box and battery carrier.This price of $590 has been subsidised by Remo Racing as this would normally cost $1100.00 +gst.

 


WHY DO I NEED TO CHANGE MY OLD GREEN AND RED BUTTON (BLACK BOX) IGNITION?

Because these OLD units are of an old analogue technology and cannot be rev-limited.

 


WHEN WAS THE DECISION MADE TO MAKE THE OLD GREEN AND RED BUTTON SYSTEM OBSOLETE?

This did not happen overnight. Back in 2005 Remo Racing wrote to the AKA and notified them that SELECTRA informed IAME ITALY that they have been put on notice that in 3-years time the Green and Red button (Black Box) would no longer be available because of NEW TECNOLOGY coming for the KF1 and KF2 Engines. These engines are electronically rev-limited to produce a low revving long-life engine.

At that point, Remo Racing applied to the AKA to have the DIGITAL 'K' Ignition homologated for 2006. As this was the first year Leopard was eligible for National Championship status it was felt that this was the ideal time to introduce the NEW TECHNOLOGY. The longer we left it the greater the effect would have been as we saw a growth in the class when the National Status was announced.

 


WERE THE LEOPARD OWNERS OF THE OLD GREEN AND RED BUTTON (BLACK BOX) NOTIFIED OF THE NEW TECHNOLOGY BACK IN 2005? AND SO WHY WASN'T WHY WASN'T A REV-LIMITER INTRODUCED IN JANUARY 2006 AT THE SAME TIME AS THE DIGITAL 'K' WAS INTRODUCED?
Interesting question... Simple really... When we first introduced the DIGITAL 'K' in 2006, ALL previous engines sold into Australia had NO REV- LIMITER as it was analogue system.

To make the KEY START DIGITAL 'K' IGNITION competitive with the 'old Analogue System, we needed to have a higher RPM, because all of the pre-2006 leopard engines out there could not be rev-limited as they were an analogue system (black box).We wanted to give the karter with the old green and red button a 4-year faze out period so they could get lots of use before they needed to change to the new Digital K.

By having a 4-YEAR FAZE-OUT period there were alot of the OLD ANALOGUE SYSTEMS GREEN AND RED BUTTON (BLACK BOX) which would eventually malfunction and need replacing. Seeing that the electric start was relatively new in the karting world, as time went by it was shortly realised that the reliability of the original system could be seriously improved on.

For example: if it ever rained and you did not have a cover over the Green and Red button it would fail from the moisture egress, and on the other hand with this new Digital K ignition it is similarly used on Motorcycles in Italy and they could withstand being out in the rain without any problems. In other words things move on and keep improving, for example in motorcars they had a points ignition and today they have digital electronic to improve reliability.

 


WHY INTRODUCE A REV-LIMITER AND WHAT BENEFIT IS IT FOR ME?
The Leopard engine is REV-LIMITED now! But at a much higher RPM of 17,000. There are other TaG engines out there that are already rev-limited to much lower than the proposed 15,800 for Leopard.

This NEW REV-LIMITER reduces the revs to 15,800. It will make Leopard Class more out-of-the-box racing; achieve much much longer engine life in between engine re-builds, resulting in a real COST SAVING to the karter.This was IAME's original philosophy with this engine.

As time went by competitors were constantly revving their engines to 17,000, causing engine failures. And so at this point we needed to take control and introduce a rev-limiter to increase reliability and provide an even playing for all. These changes are going to be cost effective for the karter and ultimately save on the cost of rebuilds due to the longer life of the engine. If you look at what is one of the most popular classes in Australia, the Yamaha class it is successful because of its reliability and performance. The end result for Leopard will be a much longer lasting engine due to the increased
reliability, very similar to the Yamaha class just with a higher performance level

 


WHAT DO YOU THINK THIS WILL DO FOR THE LEOPARD CLASS IN THE FUTURE?
There is no question that there are going to be some disgruntled customers out there, but for every one complaint we are receiving we are receiving 9 commending us for taking control and introducing the rev-limiter to bring this class back to an affordable level to run. The bottom line is, I will guarantee it will be a cost savings to the karter. And karters will more than recoup their money in the first few
months.

 


IS THIS REV LIMITER GOING TO MAKE THE LEOPARD CLASS MUCH SLOWER?
No not at all. Preliminary testing we have done has proven that by lengthening the exhaust pipe and removing 4 to 5 teeth the engine is around only 2 tenths of a second slower than what they are today. But I am certain this time next year we will be all taking about this rev-limiter at 15,800 and saying to each other "I can't believe we are faster now that what we were".

Just look at the Clubman control pipe, everyone whinged how terrible and slow the new clubman class was going to be and now we are faster than what we ever were.

 


YOU AS A PROMOTER, IT IS A PRETTY BIG MOVE DOING SOMETHING LIKE THIS, YOU MUST BE GETTING SOMETHING OUT OF IT?
Yes I am getting something out of it. I have a passion for this sport and I have a passion for Leopard Class I have worked so hard over the years to build this class up and I want it to stay.

The way it was heading, with its running costs it was destined to fail just like the high performance classes have over the years (International, Reed,Class Australia and so on)

These classes were all too expensive in the end.So I did it for the benefit of the Class as I had a vision, as I have seen what has happened in the past and I wanted a class that had speed, reliability and is cost effective for the karter.

If I was thinking of my pocket I would leave the class as it is now because I am selling plenty of spare parts as the engines fail because of abuse.

Remo Racing has built up its reputation over the years as being a fair and honest company to deal with. And by leaving the class the way it is it was not being fair and honest to the customer.

 


WHAT HAVE YOU GOT INSTORE FOR LEOPARD IN 2009?
The details are still sketch as we are getting lots of input from various Leopard competitors around Australia for what they think is best for the class. I am evaluating all ideas and will come up with a NATIONAL LEOPARD CHALLENGE.

There will be another Leopard series in 2009 but, with a difference! I will be announcing the news Series soon!
