I think that graph is the torque curve. Either that or it makes outstanding HP just off idle!

Er, I can get similar results just properly mapping a stock Griso, but still maintain the top end power. I'd suggest the stock Griso curve is just what it seems to be. Stock bike, stock map.

Vasco DG · « **Reply #32 on:** July 31, 2015, 07:24:14 PM »

Yes. Stock bike and map would be my guess. Reasonably accurate dyno too depending on temperature and altitude. Every *Healthy* stock 8V I've dynoed (At 800M altitude and usually about 30*C) has stuck out 96 on the button at the rear wheel. Highest I've seen was 104.8 from my bike but the dyno has been recalibrated since then. Mark and my bikes were both puting out about a hundred last time we went there. I can't see anything to crow about in that chart which doesn't surprise me as the intake and exhaust systems are all wrong.

"The most interesting bit to me was Pete's comment on airboxes. I never understood the technical reason behind them. Still not sure I get it, but it seems to make sense"

It's driveabilty. You get your best control over air/fuel mixtures when you have available an adequate source of fairly calm air with as little turbulence as possible. Those pleated filters look good, but I've always found them to bothered greatly by crosswinds, turbulence from large trucks, etc. Look at the airbox on a stock Cal II. That big old proboscis wasn't engineered like that for fun. And if you are oiling those pleated K&N types, there's another variable, how much is just right and how can you get it oiled the exact same every time? If I'm not using a stock airbox, I'm fiddling with a dense foam pod, no oil.

I've been away and not able to follow this thread.

Some of the responses don't surprise me, lol.

1. This who consider the Ipothesys ugly- fair game. You cannot argue aesthetics. Everybody is entitled to their own opinion.

2. Those arguing pseudo-engineering comments about the bike not working are displaced by reality. I've had input back from TLM as
well as others in Europe. Blackkat has posted one of the dyno runs. The bike handles and performs well with the mods made and the tuning supplied by Ipothesys.

The Ipothesys is not intended to be a utilitarian type bike. If we judged a machine strictly on those terms, we may all be riding an Aprilia Mana! lol.

Don't listen to us leafman. Our opinions only matter to one person - ourselves.

If you want one, buy it!

beetle · « **Reply #36 on:** August 01, 2015, 06:52:44 AM »

On another note, which exhaust were those dyno runs done with? There seems to be two different exhausts.

This one:

Is noticeably different than this one:

Each will produce a completely different torque curve.

blackcat · « **Reply #37 on:** August 01, 2015, 06:59:12 AM »

It doesn't say what mufflers were on the bike for the above run.

leafman60 · « **Reply #38 on:** August 01, 2015, 01:00:29 PM »

Doesn't matter. The engine was tuned for any variation in exhaust shown. Some of those pipes were the early prototypes.

The thing runs like a scalded dog. Very good on the track too.

The greenie bike is awesome.

Leaf- personally, I think it looks fabulous. White or tenni- it is unique, yet still not identifiably Italian.

leafman60 · « **Reply #41 on:** August 01, 2015, 04:51:01 PM »

Hey, thanks for everybody's input on this.

I have not decided for sure what I will do.

I am currently waiting on a response from the Ipothesys folks to give me a total complete quote with shipping.

I talked with them last week but I am thinking now they have closed up shop on gone on vacation! holiday!

Sheeze, I even got an email today from my friends at Teo's place who were feeding me info and THEY have closed up and gone fishing too. They're in the Netherlands.

If I go any further, I will update later.

rboe · « **Reply #42 on:** August 01, 2015, 05:12:25 PM »

Two points: That last shot, the green one, oh man, starting to look good to me!

Two; I submit that the map must be different as the exhaust being split like that will negate the need to have an offset for the on cylinder due to the weird exhaust on a stock Griso.

Addendum: Torque curve looks great! It would be nice to have a ride report and direct comparison to a stock 8V (like I'd get one anyway).

leafman60 · « **Reply #43 on:** August 01, 2015, 05:19:58 PM »

Tuning is a non-issue. Good lord. The thing is designed to work and it does. I've talked with people who have ridden one and it is phenomenal.

I was expecting to quell the thread but I just heard back from Ipothesys and they are working me up a deal that will be sent to me at the first of the week.

Yes, the greenie is stunning. I may go with that IF I pull the trigger.

I sorta like Ipothesys, too. But with a Griso being $12490 and a Motus being @$35000, I'm really wondering what they've done to the Griso to make it cost as much as a Motus.

Seriously. Three times the price of a Griso for an Ipothesys?

If I had the cash, I think I'd take another look at the Motus.

The base Motus MST is about $31,000.

The Ipothesys should come in below that. Total price is dependent on what is paid for the donor Griso.

I'm thinking I'd want an ABS Griso and I don't think those are out yet, are they?

Vasco DG · « **Reply #45 on:** August 01, 2015, 05:30:24 PM »

No ABS on the Griso and I don't see where the pump can be put on the bike as it is, there simply isn't space. Only way I could see them doing it is to mount it in front of the engine a-la Capponord.

Actually, it's still a 2-1. Look again.

Of course the map is different. You don't get a massive change in torque like that from just bolting in a new exhaust.

Yes, two into one, but their lengths are fairly equal vs. the odd plumbing we have.

pebra · « **Reply #48 on:** August 01, 2015, 05:56:25 PM »

Hey Leafman,
Do you remember the early Griso styling exercise, Calibro or something?
I think more brutish to the Ipothesus elegance?
I can see that Ipothesus speaking to you. Please keep us posted.

You still need a delta for the right cylinder. For any 2-1 system, actually.

Vasco DG · « **Reply #51 on:** August 01, 2015, 07:07:28 PM »

Firing spacing has a major effect on cylinder fill and therefore delta.

ABS will be mandatory on bikes in Europe in 2016. So mandello has to come up with a solution soon - Or it's the end of the griso.

Calijackalbob · « **Reply #54 on:** August 04, 2015, 12:32:09 PM »

Looks wicked. To me it's all about the fairing, seat and tidying up the arse end. I like the relocated number plate coming off the rear caliper mounts.
Personally I love the stock Griso "siamese twin" exhaust. If I can get my hands on one of the 10 or so Grisos in Singapore I'd love to put the Ipothesys bodywork on it, but would probably just go for the cheaper option of fitting a similar bikini fairing off a jap bike or maybe a ducati 900 ss fairing like this.

Leafman, to each his own. If you like it, do it. Screw those that bag it. You are the only one who has to love it. I guarantee you will get loads of attention on your bike if you do.

I looked hard at the Kid's Grease O this weekend. I don't see a way of packaging the ABS stuff unless it is considerably smaller than what was on my Norge. Even then I have my doubts..

I am waiting on a price for the fairing, screen, headlight, and handlebars.

Another version of the Ipothesys will be an announced before year's end. No details yet.

Not familiar with the term "delta" maybe American/Aussie language difference-what is it?
