ESE's works engine tuner

[koba]

It'd be a pointless rule change.

It would have a point, it would just miss it! I think most rule changes really don't work as intended.

[koba]

Up until recently 20+ hp 125 F4 2 strokers were not that common. Every one pretty much thought the 24mm carb rule was what was keeping them in check and with a bit more power they could blits the FXR's.

You guys certainly have surprised and amazed a few people (me at least) with how much power you have squeezed out of the old lumps.

Interesting conversation, couple of things to add
1. The FXR is not linear in its power delivery, its basically flat from 8 to 12.5k (all 15hp of it).
2. The ESE 2 strokes produce more power than the FXR's from 8.5k on
3. Skilled throttle control on the ESE bikes will walk all over the FXR (as seen on track with Avalon Biddle out driving me on all but one corner, and then she was probably taking it easy on that particular corner)
4. 20hp couldnt be enforced but is really only a pipe dream for the majority of FXR owners anyway.
5. Just picked up a new stator for the FXR so the bike will now rev past 10.5k

20 HP rule is to late for over 15 years bikes up here and down the line have had more than 20HP mike G dave D,jason and others have had 22-26HP,back then no one realy let on,as the GP was the big race to win as it is now.
when we made up the 125 24mm carb rule it was never to hold them back but to make them even with 100cc water cooled bikes,i think there are more around now like ESE s fast one,because the GP is only 15-20mins not 45min like the old days,air cooled motor only start losing power after 15-20 mins.as for Kel FXR getting gapped out of a corner by AV some of that has to do with a 100kg FXR road bike frame and a 70kg alloy RSGP frame.

Haha, yeah you guys can have all the power limits you want, but it won't make it out of Auckland. Impossible to enforce without on track dynos so I'm not sure why anyone would even bother to mention it.

[Buddha#81:Me]

I'm more for all riders having to weigh in at 100kg.......dave you can be 90 when on the 50!

Now that would slow the 60kg young fullas down, their skinny wee legs would snap off and shoot up their clackkas with that much extra weight.

[F5 Dave]

I'm 80 & probably a sight more in my armour & leathers. Does that make you feel better or worse?

[jasonu]

I have heard talk from JC of Buckets being limited to 20hp, I guess this is a Mt Wellington safety thing as it would make no sense to limit Buckets when they run on the bigger tracks with 250’s and Street Stocks.

I think this is a total wind up. Nothing more, nothing less.

However, if not...
From what I have read, seen and been told most of the safety issues are caused by too many bikes on track at one time. Maybe a 'C Grade' is in order. This will further seperate the faster bikes from the slower and make things safer for all. The organisers will have to make good use of the available track time to accomodate the extra class though.

I was a little dubious of this a looked it up but is this curve typical of a race tunned FXR150.

But I did check out your dynograph on Fzr150.co.nz and she sure is flat like a tractor.Crickey dick

I am guessing its fairly stock with this rate of delivery.

Some of you may have heard rumors of a 29.5hp bucket, I was a bit of a skeptic so booked my FXR for some dyno time with the guys who tested this supposed beast.
Assuming I have managed to attach the dyno graph - The blue line is my FXR 16hp, Red line tuned GP125 21.7hp, green line speedpros MB100 at a staggering 29.5hp, thats 82% more power

Every one under 50 years of age, should also have a KG added to their bike for every year they are under 50.

[F5 Dave]

Talking of 50, I hear that that is the new capacity limit for all buckets. Four strokes will be allowed to stroke a couple more times, but that is all.

I like the Idea,
Weight for age after all,Its aceptable to do it in horse racing and they do also handycap the riders too.and have a minimum weight too.
Also The Jockeys in horse racing are all riding mounts of the same level of horsepower.1! Sorry I couldn't resist that one.

Not all engines are created equal remember.

Not all engines are created equal remember.

Now thats more like it thats a real 4 stroke racing engine curve

Some are more equal than others !
