Thanks Tim (TBT, lol), but I see it differently
I already have bought two Laser oval carbon cans, and since they've got carbon sleeves, they don't weigh a thing anyway.
Besides, 6 feet of 1.5mm thick stainless will not weigh a whole lot more than 3 feet of the stuff + an alu plug either.

And I actually like the look of two cans more than that of just one can, makes it look more symmetrical, more aggressive and the weight is distributed more evenly too (as opposed to hanging one can on one side)... especially since there is a Ducati 748/916/996 monoposto rear end on it, wich sits quite high to the eye.
Sticking with two cans sticking out the sides will 'cover' the large opening, giving it more of a finished look than a big single could.
I was thinking of aiming them a bit up and in, like on the Suzuki TL1000R for example

And other Tim, I can't ever ride or drive something bog standard... it doesn't have to be all noisy and flaming, but I just don't like 100% standard vehicles.
I'd rather buy a bus ticket than to never modify my vehicles... and I really really really hate public transit.

I believe you can shim the original needles with tiny washers. I can't remember who's done it on here but try a search. With the DynoJet kit the needles have a longer more gradual profile though.

Hey:

This is a good option if you just need extra jets :

Hey:

"stefan2m @ Dub, You say +1 on the needle, but they're not adjustable... isn't that why I would see benefit from a jetkit"

3 or 4mm stainless washers make great needle shims, work fine on stock needles. get about 16 but probably only need 8.

Hey:

Also on the restrictors I think France and a couple other Mid European countries tried the 100 BHP limit because it was that way in Japan in the early to mid 90s. So they are in some European bikes as it has been on here before, as an issue about down on power, I think it was a Danish or other Scandanavian rider on here. They are clearly shown in the workshop book/Fiche.

Wow, never knew about that, thanks Dub!
Even weirder that it's like that in France, for example; kids can drive mopeds from their 16 birthday, maximum of 49.9cc (anything over that is considered a motorcycle) and restricted to a 45kph speed limit for the vehicle, but in France you see the kids on unlimited speed/power 49cc mopeds.
By the way, in Holland you can get your motorcycle license at 18 (though restricted to 25kW for a maximum of 2 years or until reaching your 21st birthday).
You can drink a beer or wine though at 16, spirits and so on from your 18th... weird huh!

By the way, I'm not looking for just the jets; I'll assume a respectable tuner has them in stock, I will not be fiddling with them myself... I want it to run exactly right with a dyno print including an air/fuel ratio graph, not the 'hey, it runs pretty good right out of the shed' kind of right.

Hey:

It did not work the 1st time so we will try it again?

EU Considers 100BHP Limit for Motorcycles... Again - autoevolution

That was last year the bill is still in the EU as they take forever on some things so watch for this.

100 horsepower limit threat
By Steve Farrell
MCN News Link:
Motorcycles could be subjected to 100bhp power limits under proposals to be set out by the European Commission this summer.
The Commission is expected to propose European-wide consistency on the issue, raising the prospect that countries will have to change in line with France, where a 100bhp limit is already in place. (Stupid France!)
The Department for Transport (DfT) has asked British motorcycle groups for opinions on the plans in anticipation of the consultation. A spokesman for the Motor Cycle Action Group (MAG) said: “The DfT has been asking us for our opinion on this and we’ve very clearly come out against a power limit for the United Kingdom.” (Yeah Brits!!!)
He said the proposals were also likely to include ABS for all new bikes. “A 100bhp limit is back on the EU agenda as part of a package of fresh controls which includes mandatory ABS.”
A draft version of the proposals published last year said of the current inconsistency between countries: “This creates a situation where a motorcycle above 74 kW [100bhp] type-approved in one country is refused in another one. This type of situation is not in line with the spirit of the internal market.
“On the other hand, it emerged from dedicated studies that the link between engine power and increase of safety cannot be demonstrated. Based on this, the Commission intends to propose an harmonisation of the EC legislation on that matter.”

This story is complicated, however, by various European country’s complicated (by US standards) scheme of requiring successively more difficult to get riders’ licenses for more powerful bikes. Were the 100 HP limitation to become EU law, it would likely apply to present “unlimited” licenses holders, requiring that they get a more advanced licenses for bikes with more than 100 HP, not the outright banning of such machines, at a proposed higher licensing fee..

I don't see that being approved and implemented anytime soon, especially since even in the poorer countries in Europe, people are voting more and more right wing liberal parties in stead of the socialist parties... I don't know how it is in other countries, but in Holland only the left wing parties are opposed to freedom in transportation (if it was up to them, we'd all drive the bus/metro, train, or a Prius if there is no other way).
And this is the first time I've heard of this proposed bill.

Just wondering; if I were to fiddle around with jets myself, what size would be a good starting point with my setup?
So four individual pod filters, 1987 VG80 carbs, 1995 engine with a healthy compression, a stock exhaust manifold with two straight through cans and ambient temperatures between 60 and 80 degrees Fahrenheit?

Hey:

I would go with 4 each 114, 118, 122, 124 as these carbs are jetted rich from the factory, go 114 then 122 and space the needles up with 1- 2 washers to start with it and see where that takes you. It will take a little fidling but, your on pods and its not so bad without the airbox. Good luck

There are #116 main jets in the carbs now, but I've got no idea what afr the bike has, other than that it feels a bit 'lagged' when I cruise along and suddenly twist the throttle wide open... I feel this is due to a sudden surplus of fuel,
So would it be better when I just try to run the bike with the 116 jets, or the 120 that came out?
