New owner, introduction and some questions

[BigBSBusa]

Feel and hate the frustration you are feeling. The board always has ebbs and flows. Hate it, but it is reality. Certainly don't want you to post less about things as it would be a loss for us all, but understand the rationale.

I celebrate 24 years on the board today, so maybe I'm just being hopeful that others can be around that long or longer.

Actually only 22 years. I must be getting old.

Welcome to the ORG. You will be assimilated.

Just re-watching Season 2. First encounter with the cube.

[Sl@Sh]

There are reg/recs made for lead-acid batterys, and there are reg/recs made for lithium batterys.
There is a reason why.
I never said if happened often either, but it Does happen.
A reg/rec for a lithium battery is cheap insurance that it does not.
It's the individual's choice as to whether or not they do.
Regardless, it is a real enough thing to mention.

I put a Shorai lithium battery in the '18 Gsxr1kR over 5 years ago, and still have no issues.
And even agreeing with your post...mosfet being bad for lithium...so a different reg/rec is needed...and sold for use with lithium batterys.
Yes, the lithium batterys should not be able to overcharge, so when either reg/rec fails...the battery isn't 'absorbing'(for lack of a better term) the extra charge...it justs goes out and melts plugs, wiring insulation, etc
I never said that this was common either, but rather that it Does happen.
There are threads from a few members here who have personally experienced this.
And given that people read these threads for years to come, it's simply and FYI to be aware of.

With parallel rectifier extra power will be shunt to ground but this will increase stator heat significantly.

PS with "dedicated" lithium rectifier you cannot go to the track as they do not work over 10k rpm, so battery can be depleted, same story with series rectifiers thats why suzuki and many other manufacturers still are using old style rectifiers which can still charge when engine rpm is over 10k.

Very good article Grant Tiller | Exposing the Market Leading Regulator/Rectifier

[Sl@Sh]

My understanding is that the battery BMS is protecting the battery from overcharging. Mine is Antigravity ATZ-10 with BMS.

Yes, but somewhere extra charge needs to go, old fashioned rectifier will shunt extra power to ground which will make stator and wiring hot, series rectifier will be overloaded and fail.

[Cruising180]

And
To no one specifically, but to all in general.
Myself and I know of a few other members who are really getting sick and tired of all of the trolling like answers.
First of all: I do Not believe that I am the end all of motorcycle knowledge, I still make mistakes, and I will be the first to admit that.
However, I have been riding and wrenching for over 32 years, all aspects, engines, transmissions, suspension, everything but dyno-tuning.
I am also very fortunate to have friends and family in engineering, machining, and physics, so I have direct access to people Alot smarter than myself.
I have also been fortunate enough to personally experience some of the strangest problems that most of us only read and wonder about, rare, but seeing is beliving.
When I speak about things, and I say that it is uncommon, but can happen, so beware...that is exactly what I mean.
So, when the comments are "I don't think that happens very often", very good...that is exactly what I said.
Or "I don't think that can happen"...cool, think what you want...but do some more research first.
I come here because I like the core group...even the guys that I disagree with on off-topic subjects.
I have been able to help a few people over the years too, and I am glad that I could.
I also have thick skin, I don't get offended or get my feelings hurt.
I have however had enough of the people in multiple threads that always have their 2 cents of nit picking.
Again, I'm not always right, and never said that I was...but when I have personally experienced things, and try to help someone with that information, directly in a thread, for them And future site visitors, and information that can be fact checked...just be quiet and move along.
I don't need the argument of 'that is uncommon' or 'I haven't seen that', or 'I don't think that can happen'...then go do some reading, ask for a second opinion.
No, no one has to take me at my word, but I'd like to think that in over 16 years, there are some here that do, as I have proven myself competent in what I do over the years.
And, this is in no way, 'how dare anyone question me', but rather, If I comment on something, I have seen it, done it, and fixed it...and am trying to help the next person.
Doubt that? Want to ask questions and debate it? Fine, that is perfectly ok.
But, the blatant, 'that can't happen' bs...just keep it to yourself, as I've had enough.
I will try to back off from answering anyone I don't know anymore, and I have been on here less lately too, as all alot of it has become is people looking to argue...not ask or debate like civil people do.
Rant over

I feel ya SIx. I remember we had a bit of a spat early on in my time here. I'm glad we were able to work that out. You are a welcome wealth of knowledge. I prefer forums to other places like facebook groups because the people here tend to be more real/serious and not randos on the internet treating every conversation like it's a confrontation. Sadly I see some of that "terminally online" mentality creeping up on here.

[stgatev]

I must be really thick... who offended who, and how? I do not see anything offensive so far. Disagreeing is not disrespecting. And I do not see even disagreements, just nuances and points of consideration while discussing an interesting topic.

[pashnit]

Of the Akrapovic and Yosh AT2 that I would consider, I prefer the looks of the AT2. I have seen several comments saying that the AT2 is loud. Since "loud" is always relative, I am looking for something to relate it to.

My Gen3 came with 4-in-1 Akrapovic with no cats and the ECU done by Moore Mafia. I added the silencer to make it even quieter. Not loud at all.

Adding the DB killer makes it a wee quieter - what did you decide?

That looks great. Is this a Gen 2 system adapted for Gen 3?

It has to be, as this pipe is not listed as available for Gen3 on the Akrapovic site, but it bolts right up as a Gen2 system.

The AT2 exhaust is on. ECU is tuned for the exhaust. I decided against Gen 2 cams because my local tuner does not have a map for them. I will ride it like that for now will look for options later if I decide to go for it.

I finished work later last night and didn't start it. Today is the day!

I removed the radiator and had to drain the coolant. I replenished the coolant with the OEM Suzuki "Super Long Life Blue". I filled the radiator until it topped out. Squeezed the hoses to "burp" them. Overflow bottle is half full. Any other pointers on refilling the system?

Our own @c10 does this........and now so do we......

[stgatev]

The dude is strong! Respect.

[stgatev]

Did a 100 mile ride. The noise volume from the exhaust is, in my opinion, just right. It is quieter on startup than my Panigale, and on the go, it is enough to know where I am in the revs, without being tiring. I always ride with ear plugs.
I have the noise insert on order, but may end up not installing it.

I did exactly the same thing yesterday. Before putting the faring back on, go for a short ride for a couple of blocks, let it cool down, and you'll find it'll need to be topped off again, then she'll be right.

Yep. I let it idle for a bit on the driveway while checking my exhaust work for leaks, then added some coolant, then repeated and added just a little more.

Many years ago, on a supermarket parking lot, I saw a Hayabusa and decided that this is the motorcycle I want to ride one day. Today is that day. Yesterday I picked up a gently used, in pristine condition, '23 Hayabusa in Thunder Gray / Candy Red.

I had many bikes over the years, some with even more power than the (stock) Busa. Last few bikes were a couple S1000RR, Tuono, and currently a Panigale V2 which shares the stall with the Busa.

Some mods are in order. I already replaced the lead-acid battery with a lithium one, heated grips and a tail tidy are coming in soon. Next is exhaust.

I read all about exhausts that I could find on this forum and other places before I bought the bike, and before bringing the bike home I have settled on a couple of R77 slip ons. However, now that I have the bike and have moved it around and negotiated its immense size, I decided that a single, more compact exhaust and a decat headers are much needed in order to reduce the size and weight.

Of the Akrapovic and Yosh AT2 that I would consider, I prefer the looks of the AT2. I have seen several comments saying that the AT2 is loud. Since "loud" is always relative, I am looking for something to relate it to.

For example, on my Panigale, I have a full Akrapovic under belly exhaust. Standing next to it, it is very loud, too much, but riding it, it is very pleasant in allowing the engine to let me know when it is happy.

On my S1000RR, I had a full Akrapovic system with a short can, and it was obnoxiously loud. Riding it was epic, but tiring, and firing it up in the morning was shaking the the house and waking the neighborhood. I removed it in just a few days because I felt like a complete bobo.

My son had an R77 with decat header on his little CBR300, and it was very audible, but I could live with it.

My Daytona 675R had a R77 with the stock headers (with a small cat), and it was borderline too loud for a prolonged ride, even with earplugs.

I have given these examples as some that I love, others I can live with, and others yet that are just too much.

In the absence of objective data, i.e. decibel measurement at a set distance at set RPMs, can anyone define the AT2 "loud" in relation to the above examples, or another?

Thanks all, and glad to be here. Looking forward to learning from you all!

I have installed last year the yoshimura full system 4/2/1 , which comes with the AT2 muffler. I've heard the system run with this muffler and yes it's loud , under New Zealand warrant of fitness law , does have issues around compliance ( noise decibels). What I've done is used the slip on muffler which is the hepta force muffler ( Japan yoshimura) obtained from yoshi America the mid pipe from the discontinued gen2 kit . Trimmed 90mm of the mid pipe of the slipon and tge same amount off the G2 mid pipe and welded the to components together as the Japan yoshimura has a different internal diameter size to American. Long story short , what that allows me to do is basic adapting to muffler, turning it into full system as shown in photos attached . The hepta muffler suits the bike profile lines similar to the older R77. Having it dyno tunes and ecu reflashed gives me a power increase from 164.87 hp @ 9.70 rpm to 185.75 hp @ 9.50 rpm ( this rear wheel hp , crank hp is 200 hp . Torque increases from 102.17 @ 6.67 to 113.97 @ 6.87 .

Now that’s a decent looking exhaust can. I feel everything for the 3 was rushed with no real thought on following lines like everyone did with the 2’s.

[stgatev]

Indeed, very good looking setup.
