[QUOTE=NO ONE;52656083]Yeah but what if you want to put on some wider tires/wheels? Won't most stock pins be too short/the wrong diameter?
The more I think about it, the more German engineering, on the more pedestrian level, is like American engineering. Sportier German cars are a different direction, but normal folk cars seem to carry over the same questionable, and sometimes outright bad ideas that American ones do.
I still fucking love Germany though, gonna visit one day, maybe eventually move there.[/QUOTE]
My alignment pin does just fine with both my 15x6 alloys and my 17x8 alloys (the pin diameter is no larger than the threaded shaft of the bolts btw). I'll also take a typical quirky German car over a typical American car any day as the German stuff tends to have these "oh we thought of you" touches like heated mirrors that automatically turn on when the temperature dips below 50 degrees, fuel coolers, vinyl that still looks new after 200k miles, and novelties like power headrests.

I drove all the way through Kansas going 90mph at ~4500rpm in my 3-speed Dodge Daytona with the AC on. It wanted to die.
Only drank 4 of the 5 qts in the engine too. :v:
My 2000 Rav4 screamed when we were going down the road.
4cyl never again all hail the V8
Noticed that starting last week the car was pretty much dying as soon as I cranked the engine in the morning and after work.
Took the battery in today to get it load tested. There's 200 cranking amps missing after only four years.
Dammit, now I gotta find a new battery.
Honestly that's better then most batterys.
Batteries have became junk.
My truck, between the 7.3 IDI, no overdrive on the T19, and 3.55 gears, is screaming3600rpm bloody murder flat out at 80mph. After a few hours you get used to it and realize that its running fine, it just sounds horrifying.
[QUOTE=MaverickIB;52655833]As far as I know, the reason why it feels like garbage with no baffle is because the engine is designed to operate with fairly sizeable backpressure. Not sure how opening up the airbox would help, I could tell the lack of backpressure was causing fueling issues via heavy backfiring with fireballs, and the revs would surge up and down as it tried to compensate.
I do intend on installing some O2 sensor eliminators to get rid of the closed-loop EPA admissions standards lean as fuck fueling below 5krpm. Will probably open up the box and put in a performance filter at that point, otherwise I think it would be running too lean in the low rev ranges.[/QUOTE]
backpressure is a myth.

That sounds terrible.
I have 4.10 gears, 700r4, on 235/85/16 tires. I have no tac, but it calculates to about 2400rpm at 80. That sounds right.
Very thankful for overdrive, i do so much interstate driving.

Heh, just wait 'till you start buying stuff for different occasions. Like daily gear, getting a new helmet for more comfort, etc. I've probably spent that same amount this season and I already had full gear!
Anyways, welcome to the world of two-wheelers. Nice to see you start of with proper gear right out the gate.

[/QUOTE]
Apparently it isn't if simply adding/removing the baffle before bolting it on as the motor was running was enough to drastically change performance. Also, bigger Monsters have a flapper valve in their exhaust headers precisely for that purpose, it shuts when idling/very low rev ranges in order to maintain backpressure.
Maybe the desmo valves make it a thing and it's a myth for other bikes, but it's definitely a thing for Ducatis.

The idea of "pressure in exhaust is good" is a myth, but its the cheap go-to excuse for people who dont want you messing with your exhaust. Having a well set up exhaust system that times firing order and header shape to help scavenge exhaust is a thing, but depending on valve open durations and many other factors, you dont miss out on much benefit from completely disregarding it. Example: I have a decent shape tri-mill stinger exhaust on my dune buggy, but Im thinking of switching to twin cannons, even though I could lose up to 5-10% of my torque from it, because they make it easier to work on the rear of the engine, and they look and sound fucking sweet.

The reason it seems that way it that the bike was tuned for the stock exhaust, which caused backpressure as a side effect of being somewhat quiet and EPA approved. When you take out the baffles, air flows more easily out of the engine, so more air gets sucked into the engine, so the fuel/air mix is leaned out. Get more fuel in there and youll see a nice gain in the butt-dyno department.
When I got my mikuni carbs for my CX500, it ran waaay rich for about a week, or until I had time to cut out the factory H-box. After that it ran nearly perfect.
Makes sense. I don't have a way of altering fueling beyond the O2 sensor eliminators I ordered. The original package was lost (thanks DHL) so I'm having to re-order them. They should eliminate the lean condition from the closed-loop, I'll try taking the baffles out after that and see if the ECU is able to compensate for it while in open-loop.
why don't you just short out the water / temp sensor and achieve MAX TILT and be done....
[QUOTE=DPKiller;52662425]why don't you just short out the water / temp sensor and achieve MAX TILT and be done....[/QUOTE]
Ducatis have a limp mode that severely hinders performance when it detects what it determines to be a major fault in a sensor. Simply unplugging the O2 sensors or some other quick modification isn't quite enough since the ECU won't want to play nice while an error code is thrown. Specific sensor eliminators designed to "trick" the ECU into not considering their inputs at all are required since I have virtually no expertise in fucking with wiring.
I dont think I could bring myself to do serious work on a bike that I couldnt tune with a screwdriver and shims.
So, all my fellow florida facepunchers ready for this shit show?
All the weather sites keep showing this bitch shifting west, which will fuck just about everyone.
Basically it is going to go right about over where I live, Pasco, which hasn't had a direct hit from a hurricane is 50~ years. This aint good, the drainage systems are all totally in disrepair and back up with the force of a Jumanji monsoon.
Good bye car and house, I barley knew ye.

Man, if you can, get out of there.

On the red, stock one that is.
Not much changed, but I finished all the wiring and completely finished the interior now. So that's like one big thing that's now finished.

No more tart button unfortunately.
Looks like I'll be going testing the 25th or 29th of this month.

That's a pretty ignorant statement, man. An engine is a vacuum. The more air that is able to enter and exit quickly, the more fuel you need. Without adequate fuel due to too much airflow, the motor will run lean and likely damage the exhaust valves over time. This is much more apparent in carbureted engines as there is no automatic fuel management, and the motor will run like ass without adequate jetting.

I bought a thing.
A thing called a Transit from 1967 that's pretty rust free which is quite rare for being this area, everything falls to pieces after a few years here.
It doesn't have an engine or transmission but it's set up for a volvo b20 + m46(?) and those are a dime a dozen so that'll be fine.
Hasn't been on the road since 1990 and needs quite a bit of work but I've finally got a camper!!
Man that will look so good. It looks to be in a really good shape. Give it a wash and show some interior pics!
Probably is a bit of rust on the bottom since rust doesn't rest, but assuming there's nothing that can't be fixed easily
Look what parked next to me today at the gun range :D

yeah like I said backpressure is a myth. no engine needs backpressure, but rather they're tuned to cope with it. it's pretty fucking easy to drill out a jet if you need more fuel.
besides that, this is a new ducati we're talking. it's fuel injected.

Yep

And technically so do 4-stroke engines with "internal EGR" (exhaust valves overlapping the intake stroke, so it is only on engines with adjustable exhaust cam timing)
