I’d like to see the cam profiles designed to work with the low 9.5-1 CR and tiny valves/TB’s

I don’t know where the centers are at with this bike but I can’t imagine dialing them back any for more low end/midrange as the bike is already tuned that way

The timing is already posted in my other threads...and there are other more aggressive profiles created than what I chose. My goal wasn't peak HP at the loss of rideabilty.

Lemme know when any other CB1100 puts down 75 WHEEL tq while NOT loosing any thing through the entire curve- but also makes that AND 104whp....

This bike is chided for being underpowered- but that's a falacy... there are many other more powerful bikes sure...that take 2-3 down@~*^s to go anywhere. That don't move until 6-7-8-9k...

be warned the power commander 6 is a lot more difficult to deal with than the 5, ask how i know. would highly recommend a 5 of you can find one.

I have one... never tested it. Honestly can't imagine what the difference is.

They claim to have only narrowed the range you can move +/- without going to a Dynojet shop- who can unlock past that (cough cough)- me.

In theory that should be a very basic software change that wouldn't change behavior.... unless you were trying to load a map beyond those limits and it was unhappy...

I found your cam thread and it looks like you picked up around 3 hp going from stock .297/.294 lift and 199*/212* @ .050 duration to .318/.312 lift and 220*/223* @ .050 duration.

Looking at only duration at the industry standard .050 the stock 199*/212* numbers are optimized for the relatively low 9.5-1 CR. Closing the intake early (199*) helps the motor build dynamic compression which contributes to the strong low end/torque performance in stock trim. Opening that up to 220* at the same 9.5-1 CR does not really help and I bet if you looked closely at the tq numbers below 5000 rpm you would see a slight reduction. Its absolutely imperative you match CR with the cam profile, this is the reason most cam comparies such as Comp, Crower, Howards ect will state a recommended CR along with their cam selections.

In the car world I had a Comp hyd roller very similar to your modified profile in my 1973 Camaro, it was 218*/224* @ .050 and was perfectly matched at 10.25-1 CR using minimum deck height, flat top pistons and alum heads





Same recipe of minimal deck height, flat tops, and alum heads with my 1969 Corvette, its got a little more cam at 224*/230* @ .050 but is matched appropriately with a CR of 10.5-1






Both run on premium pump gas. I've had the vette for 15 yrs now and just sold the Camaro after having it for 12 yrs and over 10,000 trouble free miles.

In the motorcycle world, my GS750 was hot rodded back in the 1980's. I ran multiple Cam Motion grinds out of Baton Rouge, La in it as well as a set of Megacycle cams in the .350 lift/240* duration @ .050 range at 11-1 CR. It ended up at 802cc and had a set of 36mm Mikuni's off an early GSXR1100 and a V&H Competition Plus 4-1 exhaust. It was a very strong runner that would keep up with the typical lightly modified 900/1000 cc bikes of its time.



I bought it new and at 50,000 miles I parted it out in the early 2000's and bought a new 2005 Bandit 1200. It qot the typical mods, my biggest mistake was going with a set of GSXR1100 cams at the stock 9.5-1 CR. I dialed back the cam timing to build more dynamic compression but ultimately hated it. Gutless down low and minimal top end increase for the effort. A set of stock bore 11-1 pistons fixed it and turned it into a different animal. A set RS36 Mikuni's were icing on the cake. It was very strong from 6000 rpm all the way to its 10,5000 redline



Both 16v Suzuki's had adjustable cam sprockets, the GS750 was run at the cam manufacturers recommended 110* centerline. I tried the B1200 at the same 110* centers but ultimately settled on a 104/106* combo that gave it a strong upper midrange without sacrificing top end.

Not trying to be a debbie downer but been there and done that...unless you do something about the anemic 9.5-1 CR you are simply chasing your tail for minimal reward. Couple that with being hamstrung by the tiny valves and 32 mm TB's the CB has...

I applaud your effort but at some point reality sets in...

[PowerDubs_imp]

I lost nothing through the rev range on all my modifications.

My bike puts down 25% more hp than stock- with ZERO sacrifice, all gain. Looks great, drives great, sounds great.

This isn’t my first bike or my first car- not my first rodeo.

You said yourself - your bike was strong from 6k. My bike is strong off idle. Huge difference.

My bike amazes the local bike shop / dyno owner- and he has been doing this for many decades. I have to remind / argue w/ him to start the pulls as low as he has- and on MY dyno I will pull from even lower.

He isn’t used to bikes that don’t care about 2k. My bike LAUGHS at 2k.

Does this bike need more CR?

Sure.

I’m not there yet.

Does CR make as much difference as you think? No.

On my bike- air cooled so nothing crazy is possible like 12-13-14.1- at best I could expect a couple hp at the wheel- for a LOT of work, and a LOT of money. Yea- 2-3whp maybe.

Same with valves- are they small? Sure.

Is there room in the head for more? Not really.


SO- next up the choke chain- our TB are 32mm BUT choked at the factory to 27mm.

I already showed on the dyno that boring turn out with a dremel gained power and matched what the fancy expensive TSR aluminum ones did. In fact- mine supported 103whp… and again nobody - I’ll repeat NOBODY- besides me has made 100whp on this bike.

I then went on to put in custom dual height velocity stacks- that open the full 32mm and have more cfm *capability*- picked up 1 whp

So- like any all motor engine- chase the cork- at this point we have a VERY small primary air box fed by a secondary air box where the filter lies… and that is more likely the next choke point for power.


But hey - feel free to disagree, do better.

Or- buy something else.

There are plenty of more powerful bikes.

Some even pretend to sorta look old.


I’ll stay with true to old school- and in fact have done everything I can to make the bike look as old as possible.

If I want ‘more’- enough to buy another bike- I won’t buy lipstick on a pig. I go ahead and buy modern for modern sake.

Oh wait- I have that too.


My 2022 Aprillia 660 Tuono Factory weighs less than 400lb wet and makes 100hp crank stock.

But it doesn’t START to wake up until 6k. Meh.


I’ll play with it later.. and let you know the results. I keep an eye on the aftermarket and tuners for that bike as well.. and let’s say.: I have some ideas.

No doubt you have the strongest 1140cc Honda CB1100 on the planet….only problem is my 948cc Z900RS will run circles around it in STOCK trim….and if ridden correctly it won’t need a downshift to do it as it makes max power at only 8500rpm. Not everyone rides around at 2k rpm…

My air cooled 1170cc BMW R9T was rated 110 hp at 7800rpm…not all bikes need to be wrung out to move, heck my 1100 Monster was 100hp at 8000rpm and would pull your arms out of your sockets at 4000

Back to your cam numbers, you picked up 3 hp by doing a cam swap…at what cost I ask?

At what point does reality set in?

[PowerDubs_imp]

I'll reply the exact same response to you that I did in your PM that you said 'you old guys crack me up"-


There's nothing to laugh about. I'm not old- unless you are a child. I'm not even 50 yet... but I've been building engines in bikes and cars for almost 40 years.

You don't even know the difference between rated at the crank and wheel.

Derp.

My 104 wheel is a LOT more powerful than a BMW 109 mag listed bike.

I'm guessing you are young...and KNOWING you have a lot to learn.

Your bike isn't as powerful as you think it is... and yea- you will need to downshift to outrun me.
Edit- and to anyone wondering why I posted that- the kid PM'd me and said-

"Carry on, I’m enjoying the banter and you don’t need to PM me, let’s keep it public as I’m sure others will enjoy the humor "

Right now apparently-






Compared to-


Going to bed... but laughing as I do so... my bike matches his PEAK tq when I am at 3k and doesn't drop below that until 8400... and he is talking trash to me in PM.

And your bike (stock) is above 90whp - if I am generous- for 1500 RPM.

My bike is above 90whp for 2600 RPM and above 100whp for pretty much 2,000 RPM.


"Not everyone rides around at 2k rpm…" What if... you can do both?



...and- got your pink slip? I do- and will line up- just like 'the old guys' used to do.

In fact, I was at the drag strip last weekend. It's 20 minutes from my house and I've been going there for decades. Let's party.

That seems to be the common consensus so I will likely go that way.

This isn't quite what I expected to wake up today but im with you powerdubs. Some people are just jealous for one reason or another. Its no secret that the cb1100 isnt the best bang for buck platform for making power, thats no secret. Short of forced induction there isn't much the average person can do. Truth be told, Im sure these bike could be turbocharged as a tubro system tends to be the most versatile form of forced induction. I would vastly prefer a supercharger for it however, I know they make a kit for the cb1000 which increases power by about 80 HP which is impressive, sadly though it wouldn't be compatable with the 1100. Im sure someone with enough knowledge and machining experience could make such a system. and id gladly pay for it, but I dont have the knowledge, connections, or skill to come close lol.

Dude, why do you keep sending me PM’s?

You do crack me up as you gained all of 3 hp doing a cam swap and then want to brag about it. Who has something to learn?

You stuck a 220 degree duration @.050 in a 9.5-1 motor and are then surprised that you only made 3 hp? I could have saved you the trouble…

No I’m not a kid, been flying jets for 25+ yrs and have done a little hot rodding as evidenced by my pictures. I’ve got a 69 vette and 3 bikes in the garage, not bragging but just wanted to show that I’m not a novice either.

Anyway carry on, I’m sure you can squeeze another 2-3 hp out of your build…

ive never seen someone so **** and jealous before lol. youre forgetting this man is making his own camshafts, that's defiantly something to brag about. if you have something to add to the convrosation then go ahead, if youre just going to be **** then move on before you dig the hole deeper lol.

I don’t know what hole you are taking about. He made all of 3 hp with his “custom” cam grind….I’m sure there are many lining up to spend their hard earned money on such a outstanding performance gain…why don’t you put your money where your mouth is and order a set of cams from him
