The cheater MX85 argument. I might be changing my mind.

Something to consider. The people commenting on this thread that actually sling there leg over a bucket and race represent maybe 5-10% of the 100 or more active racers around the country.


Not much will change. Old fat guys will still get schooled buy skinny kids on with less hp.

Who gives a fuck. Look around you old crying babies. You are old and grumpy, time to hang up the boots if it's all so stressful for yah.

Not sure just, starting to think about this pipe business. But when you think about the energy in the pipe I think a smaller diameter will have greater reflected energy but over a smaller rpm range.

Not sure i am still stuck at Bell with the pipes but i am pretty sure the DIA is a function of the engine size........even on the formula done from frits pipe design.
the big problem is fitting them in when the cylinders get big ie over 250 or if you have 4 of them or such malacky
Maybe they are right and its all witchcraft and secret skulduggery.........
But for me the suckiness is always a intrinsic factor of volume, with and its length for its rpm. its angles for its combination of range with is an expression of its volume also.........

thats a fair call from 2 fast riders , if it was not for f5 dave with his new 50 gettting near 14hp with such little work ( knowing once apon a time )pete sales it took years to get there, i may have a diffient view on it

That's because he's got a competition engine.... oh but that one is legal because they threw it in a couple of road bikes in Europe. It even says world championship winning or something on the side of the engine case!!!

Still legal
That is the important bit........

Maybe we should have a claiming rule like they used to in AUS top three finishers at BOB bikes are able to be brought by another racer for $3000 or something
Stop the $1000 carbs

It's important that it is legal yes, but it is daft that we ban other motors that are of the same nature because the manufactures in Japan didn't put them in road chassis.

and hell yeah that rule would be awesome!!

True, but consistent with all compromises I think you bias the required pipe diameter one way or the other depending on the results you want.

Yeah but i struggle to get beyond the buckets not as a class for modded commuters or stuff brewd in a shed.
Its just a part of what makes buckets buckets for me.
be interested to see Richs input on the claiming rule.............Maybe $5000?...........

[husaberg]

I would have to look at Wobs stuff its the one thing that still very cagdy with the two strokes even Frits.
Than again wob is in the pipe business so it makes sense not to give away everything.
Plus Jan always says they had to test everything with the pipes the formulas always had assumptions with speed of waves.
Maybe we should be having this conversation on that ESE thread....

[steamroller]

I'm sorry but this is simply not the case.


If partial throttle wasn't used why don't you replace your throttle with a switch? If you had ever looked at a data log of throttle % over the course of a a lap you would start to understand the importance of it and why engine tuners are for even in search of flat torque curves. Unless you have a CVT.

By your statement there you are suggesting the RPM does not change for each gear? So my 85 has 16HP the whole time I have the throttle open? I don't think so. Keep in mind that in the time that it's taken the FXR to shift 1 gear, the 85 has shifted 3, and that's three gears shifts of power not on the ground.

The dyno comparisons don't lie. Both bikes, same dyno same conditions.

haha we are not talking about super bikes my statement is i was in the gp given it my all to tri and win fuck all in the lap times with my bike and the 85. it was faster at 24 hp i dont no what you dont under stand with that. you should do a gp then you may see

Shit that sounds like your saying just the bike did it remember the rider. i can put words in you mouth to a.

It doesn't matter that it is not superbikes, the physics are still the same and still apply.

Maybe the Derbi seemed faster because he simply got on the gas earlier and harder. Who's to know, but I'd bet my bike that his 80 has a much peakier power curve than your 150.

and what does that matter ? you ride a 2 stroke diffent to a 4? you get use to it!!! my first race i ever won was on a rs125 in the f3 class after regan broke his arm in the morning , i had neven riden one before was on a nc24 then .. after 3 races on it i just changed my WAY OF RIDING ...NO BIG DEAL! no engine breaking ..cool . PS 8 BIKES WENT PAST ME IN EVERY STRATE. and realy what i just put means shit all..

na they now want weight rules.

Bingo.

F##K Me.

I'd rather not. Don't get me wrong I am sure you are a good looking fella, but i understand Koba's cuter, But should i believe Dave? it was weird he brought it up actually.......... to many Honda and daigo combination parts?

[Pumba]

na they now want weight rules now. so there isn't any weight advantage...

Fuck that's not new. Been suggesting that for a while. 200kg min weight limit bike plus rider. Ballast to be worn by the rider.

I still won't win but fuck it would be fun to see
