ESE's works engine tuner

Garry riding Speedpros 30hp MB100 in leg two looked to be the likely winner of the Dominic Howe and was laying down some super quick times until the rear shock came apart, dumping oil onto the rear tyre.

During the day Garry smashed the previous lap record of 29.4 with a bunch of 29's then a couple of 28.8's.

This Honda GL145 engine in a RGV chassis would have to be the best presented bike there today.

The field was mostly FXR150s but there were some Suzuki, Honda and Yamahas too.

This is the winner of the F4 GP at Tokoroa ridden by Nat D, 88. Today Nathanael won the first leg of the Dominic Howe but dropped it chasing Garry in the second.



One of the fast boys who can peddle an FXR like there is no tomorrow.



There were a few FXR's that have had 100cc Honda engines fitted for F5, they are seriously good and handle very well.



Interesting side cars.



The great thing about Buckets is that everyone pitches in and helps out. Yep that's the opposition helping their main competition get going again.

Some Pit secrets, how to mount an FXR150 into a FZR250 3LN frame. Very nicely done and the owner says it handles well and changing to wet wheels is very easy. The FZR 3LN comes std with 2.75x17 front and 3.5x17 rear wheels and 320mm front disk.

More Pit secrets, a FZR150 in a TZR frame, these specials are seriously fast.

And the one I liked most of all, a RG50 in a Honda RS frame. One of F5 Daves engines fitted by RMS engineering.

The RG50's rear engine mount slotted straight into the RS rear mount and the front RS frame mounts used simple brackets to hold the front of the engine.

It also used a light weight hydraulic Mountain Bike rear break with a thumb operated master cylinder on the left handle bar, very clever.

I would have thought Max was a bit young for buggered ankles

[crazy man]

thanks for the pic rob , looks like a good days racing

Actually the dodgy engineering to hold the engine in is Dave's or one of Dave's bum buddies. From what I understand RMS Eng employs a higher standard of engineering.

RMS engineering did the tuning work on the engine. And quite a nice job he did. Few more things I would like to change but reliable track time is still more valuable at this stage.

Hi rob i think max fitted the motor in this frame,i did some motor work fitted the pipe and made the seat sub frame,but i did fit the FXR150 motor into the FZR frame for Nick.

32.64 I think. Needs some more over rev. Or maybe just some more gear shifting. Or something. It would be good to get it on a dyno so I can see what I am starting with and where it is lacking. Even getting a tacho would be a damn good start. Could have taken elder diprose with a bit more power.

The way the motor is mounted is a very clever bit of engineering, I think better than the way we did ours ......

looks like a good days racing

It was a great day.

Hey everybody.

Wobbly, can you talk a bit about diffuser angles, ok, we are searching for the widest, lowest pressure around bdc, but in a pratical way...

For example, Mota Software (even the demo) when calculating a 3 stage header/diffuser will start the second divergent section "difuser" by 37%, and easily give ultra step sharp final 11 and 12º diffuser cone angle. If they work fine? Yes, they are not bad at all. Is the most used program here in Portugal.

For example, an exhaust calculated for Honda RS specs with 800mm of lenght will have 88 mm of mid section lenght, much more then typical Honda pipes.

What usualy happens when playing with the mid-section lenght?
Max pressure at the exhaust port, should arrive sharply as soon as the transfer close or more progressive until the exhaust close?

Many many thanks
