Other cbr1100xx Owners Websites with data?

fjahandari · 08-26-2008, 11:32 AM

Given that most cbr1100xx owners are typically older (I think the avewrage age is well above 40) I would have thought a web gathering like this with its associated ability for online storage would provide a great inventory of comparable data from many individuals including their Dyno graph data both baseline and after-mod curves, and summaries of their changes and effects; lessons learned, etc. That way we'd be able to mine the data and be able to make relatively intelligent comparissions and draw our own conclusions.

Is anyone aware of another online group of cbr1100xx rider who might have this type of data?
Thanks!

I admire you for coming up with the idea but, why not just ride the bikes? Surely that's what they're for ore than anything?

Just my opinion of course, others maybe will be falling over themselves to spend hours gathering & collating data.....

Oh you mean the WHOLE Question...? Seems, it was ignored by many on this list when I posted it as a Flat Spot at 3000- 4500 rpm. Well here it is again just for you! :-) I've since found 2 Dyno curves that PERFECTLY demonstrate this problem; they are attached too.

Bike is running well and there is generally good throttle response. However, the torque response is not linear across the entire power band. Bike starts well from idle (+/- 1100 RPM) and progresses well to around 3000 RPM, then I find quite a noticeable flat spot around 3000-4500 rpm after which it pulls like a champ all way to the redline rev zone. The throttle response in the flat spot is not as crisp and linear as it should be. So, wise ones… what do you say? Let me guess:
1- Do a few dyno runs to be sure it’s not “all in my head”
2- Completed a compression test on all cylinders 1st then do Dyno run

Like most ‘squids’ I don’t have a pre-mod baseline Dyno curve for bike. In addition, like a smaller sample of “squids”… I also don’t even have any Dyno curves of the bike after the induction/exhaust modifications with the Jardine RT-1 slip-ons, Factory-Pro Stage 1 Jetkit, ignition advancer and BMC airfilter!

Can you please send me one or more representative graphs simulating a normal stock ’97 cbr1100xx baseline along with any bikes w/similar modification (slip-on, stage 1, ignition advancer and airfilter)? This setup should be a pretty common mod for most owners.

If I understand right this is a common thing for the carbed birds.

I never knew there could be so much to riding a Bird. The only curve I know about is the one described when I come up behind a slower vehicle, pull out, pass, and pull back in again. The machine is capable of around 180mph, with 0-60 in about 3 seconds, why would I worry about all the above?

fjahandari · 08-26-2008, 6:15 PM

Thanks. I guess its not about how phast you go... but how you get that fast...

As a comparison try a relatively new ZX10 or cbr1000rr... heck even my old cbr900rr had better low to mid range... mid range is the key to most street riding... top end is fine once in a while.... sure... I'm all for it and then some.. but Mid is where we mostly function.

As you can probably tell, I agree, for me it's about the riding not the worrying about how / why.

Whatever "floats your boat" as they say..............surely enough power to be going on with is enough? I don't have a dyno map or any of that stuff but, I know my bike's quite quick enough for regular roads, the speed limit here in the UK is 70mph, so 120+ is usually enough to ensure a spell in prison - without even having a dyno graph!!

Yeah I agree. I couldnt care less about all that stuff. Just get on it and ride it I say. Id rather pump money into more mods anyway. But as I say each to his own.

I just went back and looked at the graphs from my 98, and it has the flat area as well, but I will say, with one down in the front and the other little mods I've done to this one.
I'm rarely in that rpm range, just from a normall pull off from a light or sign...And if I stick it down low in fisrt the front tire is going sky-ward so fast who could tell of a flat spot in the carbs, I'm trying to keep it off the tail light...

At the track I leave with a lot more rpm so I'm well over the flat, and cruising I'm never that low in rpm, I found mine likes to cruise around 5,000 and responce is great from there....And a flat spot in the dyno curves is genetic to most all stock carburated bikes I've ever tuned on the dyno...
