ESE's works engine tuner

[Rick 52]

Thanks for team ESE ..Great advice on port tidying and a re designed pipe gave me 1/2 a horse and a much fatter power curve ,this kept me at the sharpe end all weekend ..now I need to stop the clutch from slipping ...
Kel a pass is a pass very clean and you still had to put the power down in tricky conditions and a tidy last lap left me nothing to get you back ,very good racing from us all I think ..

and more likely to bite than the marshalls

Kels FXR was over the noise limit and he had to park it for the day.

Agreed. The racing was fast, clean and a lot of fun.

and more likely to bite than the marshalls

That was a draw, 1 each.

OK .... that was Te Puke ... So three 2-Strokes and Gav-V's FXR at the pointy end all day.

Did a quick calc and by my take with one round to go its team ESE riders 1st equal on 120, Rick 1 behind at 119.

edit: actually that should have read ESE riders equal on points, Avalon leads due to greater no. of wins. What really matters is that 2 strokes lead!

Anyone got a set of dimensions for a TZ350G - crossover pipes, dont want to measure them if I can avoid it.
Want them as a sim baseline stock engine.

Great racing this weekend, sorry about the weather. This is how it looks...

120 Avalon Biddle
120 Kel Nicolson
119 Rick Ford
104 Steve Booth
83 Gavin Veltmeyer
71 Warrick Head
49 Andrew Adlam
41 Malcolm Nabbs
41 Mike Kyle
39 Carl Smith
38 Gary Cunningham
35 Rogan Chandler
34 Tim Fraser
34 John Steer
30 Ken Douglas
28 Kamil Chodor
26 Adrian Mitchell
25 Henk Zeeven
17 Ryan Firn
15 Grant Nicholson
15 Caleb Adlam
15 Ivan Smith
11 Dave Manuell
10 Brian Steffensen

See the quiet achievers like Steve Booth waiting in the background to jump when all the 2 strokes seize and Gavin gets a free holiday to Hawaii on short notice...

Given the mix of fast guys to come out at Kaitoke it could be a very dynamic last round.

The offical Pacific Club Summer Series results after Te Puke .... Strokers making the FXR's the also rans.

Any of the nay sayers still unable to read the writing on the wall ........ with the Taupo GP next, things are getting interesting.

I'm saving this spot for a post that is going to take some careful composition.

OK, now it's composted in my mind long enough I'm posting it:

I was going to write a lengthy and thoughtful post about my quick run on Avalons bike.
The length will have to come from me padding it out with worthless rambling thoughts because my short play run can be described in one word:
Outstanding!

No, I don't mean that in the way we describe Romanian plum brandy, which stands out as the most horrid liquid substance to my assault my palate; It was outstandingly good.
Most times I ride someones bucket I mentally cobble together a checklist of pros and cons. The better bikes, all the fast ones, don't really have cons. Instead they have Pros and Okays, for example Rick's old FXR had an unbelievable mid-range punch and turned in exceptionally well (for an FXR), there were no aspects of the bike that could be considered 'bad' by any means.
The ESE built GP framed bike that Avalon has been using to humble the fastest racers out there was nothing short of fantastic.
Before I snuck out after the last B-grade race Keith quietly said to me "Careful with the brake, feel it out as it's probably better than you are used to."
Shit, He wasn't kidding!
The brake wasn't all, every part that makes a bike stop, go, turn, handle and feel good was better than I've felt on any bucket before.
I only had a few laps on it but I was instantly aware the bike was much faster than me, on my second lap I realised I was riding it all wrong because I was still trying to force it around corners rather than just looking where I want to go and letting the bike do the rest. That's a cool feeling.
The bike is very fast but in the kind of way it will take a damn good rider to make the most of it. Sorted.

So the purpose of this post is to thank Avalon and Keith for letting me out on it, even when they wanted to go home! I must also congratulate all the ESE personnel for their work on creating such a gem of an engine, if I didn't know better I wouldn't have believed it was a 1970's commuter engine, it makes all the right sounds and goes like the hyper kid after he's been fed a bag of red lollies.

I might as well save this spot for some careless compostation

you could put some of it in bottles and call it homebrew like I do...

I am saving this spot for a bunch of post Taupo excusses I have composed .....

If you show up you have to make excuses that fit reality, my excuses revolve around not showing up!

I am trying to decide wether to leave the bike as is for Taupo or to fit the new Wobbly pipe and maybe even the triple port cylinder. Its a bit of a hassle and a hours of dyno time to get the ignition curve and carb right.

The trick in looking at these curves is to not take the ultimate hp to seriously as EngMod thinks my combustion efficiency is much higher than it actually is. I could change that in the settings but can't be bothered because re running the simulations will take to long.

With these simulations the thing to look for is the shape of the curve and the power spread not the ultimate hp which is over stated by at least 3 hp and is at the crank and not what you would see on the dyno.



Red line is the current 1ex setup with RS pipe, and the Blue line is the new Wobbly Pipe



The Blue line is the current 1ex setup with Wobbly pipe, and the Red line is the 3ex (tripple ex) with Wobbly pipe.

Flat for 4,000 rpm 10-14K or a 5,000 power spread from 9-14K with over rev to 15, now thats tempting, and if we can plump up the 8 to 9 bit with an ATAC valve then thats potentialy 5.5 to 6k power spread. Guess what I will be working on over the next few months.

But what to do for Taupo, the tried and true or take a gamble ......

I recon you leave it as is and spend the time sorting the carb out
then i might be able to ride it better

[TZ350]

Yep you could be right, its fast enough now, better to leave it as is and save something for later, 33+ rwhp and 5.5k power spread, just in case the faster FXRs can find any more power.

I think Your friend Neels does i guess, his site advertising for enginemod2t uses a TZ250G as an example.

and also this guy uses the t250g as a sim example he has done if that helpshttp://www.thumpertalk.com/topic/782...tion-software/

Bell has the pipe dimensions for a TZ125G, TZ250D/E, TZ500G not that helps you much. As Mr Murphy helped him choose his examples, Maybe different editions offer different examples?
Mr Swarbrick will know them too, as he does T20 pipes to those std dimensions for classic racers as well.

My vote would be tried and true for your situation, changes can cause problems that take time to iron out or only become apparent on the day, you aren't in the position where the risk is worth it.

...better to leave it as is and save something for later, 33+ rwhp and 5.5k power spread, just in case the faster FXRs can find any more power.

Maybe you could get to 33-35 rwhp, but you don't need it now, keep it like money in the bank then the FXR's will always know you can easily pull something out of the hat and stay ahead of them whatever they do.
