ESE's works engine tuner

[Yow Ling]

Has anyone tried using a different means of determining engine load? With a four stroke you'd be able to use a MAP sensor. Is that feasable on the 2T engines? The carbs used on these bikes rarely lend themselves to actuating a TPS.

EGT would be an indicator, mass airflow would probably be fairly accurate indicator, accelerometer, torque sensor, but I would have thought TPS would be the worst as it only shows TP not load

I may have to try it one of these days. It'd be a neat and tidy solution if it works.

Here you go Rob. An update on the NSR300. At the end of the lap the other 300 comes into view.

Disclaimer. The EGT is reading wrong. Its earthing out on the mount and reading hi. And the rev counter not working so just don't look at that.

What rpm are you gearchanging the 300 at Rich ?

Hard to know till I get the rev counter working again but should be around 11700. Peak is 11800.

The box sounds really wide ratio on the up shifts.

Yeah its the normal street one. I like it. Just needs a taller 1st. Other bike has close F3 box.

Great work guys.
There was a lot of talk around the paddock about these Speedjunkie/fortyfive racing NSR300s.
You guys should be proud of the time and effort you have put into them. Clearly the best presented bikes on track and boy do they go....

Do you have the full video of the last "carb class" race? Missed it dealing with the juniors...

Sorry mate. I wish I did have that on camera. I didn't film any racing that day. Won't make that mistake again. Team NSR300 going full bucket racer mental at each other from the first corner.

And thanks Team GPR for the 6 more hp on friday night

Bum. If the last Superlite race was anything to go by, it must have been a corker...

And cheers for the plug. The GPR boys have enjoyed helping out. Getting a real understanding of these igntech. Now it's time to sort out the powerjeting and TPS based maps.

Sounding nice Rich, and looking like its haulin.

I'd be interested to hear opinions good or bad on any of the racing plug electrode configurations (hopefully) attached.

I use the flat type, third one back on my Kawasaki, on ethanol fuel and heavy oil mix. Never fouled it yet. Ignitec fires it through both channels at once.

You need serious spark voltage for the surface gap plugs. Obviously you do have...I'm impressed.

As an aside you can get preignition - or autoignition - with surface gap plugs. They're plated on the large ring electrode, i've had the plating flake giving sharp, hot edges...Just machine a tad off.

The middle one is the type developed by NGK for Honda RS125/250.
Been there done the dyno work - those special tip type plugs make more power - end of story.
They were originally a short body type, and cost a fortune, including the special short cap as well.
The R7376 has a normal body with that electrode configuration, Platinum fine wire earth, and Iridium fine wire centre.
Kicks arse with the Denso equivalent and the B10EGV type simply isnt in the same league.
