Define: huge increase in power

[Horse]

The odd thing about all these power gains, is that most of us never, ever use anything like the full potential BHP of the bikes we have.
And for the real world I would have thought concentration on low down torque would be the only thin most people could "feel"

The guy who served my bikes always balanced the injectors for part throttle / midrange as that's where most riders spend most of their time.

I've got 202 gee gees, but would happily accept another 30 at Portimao next week

That would be fun down the long straight

I was reading some blurb from a tuner about what they'd done to a bike (akra, air filter and ecu flash)
So after spunking the best part of a grand on bits, anyone care to guess what % or hp gain they received, described by tuner as a 'huge increase in power'
I know that my bike, with the older version of the same engine actually dyno'd slightly higher with pipe, filter, airbox mod and flash, and allegedly, has a lower initial output, so a bigger gain (i only paid for the flash and air filter)

5% gain overall. But generally speaking it isn't about power gain its about power delivery, smooth with no dips.

Has nobody looked to find out what colour the power band was yet?

[Ditchfinder]

Just to expand on this what would you good people define as a noticable reduction in weight?

EG. On the Himmy quoted wet weight is 199kg - I think I've dropped around 10kg with removing racks, lighter exhaust and a lighter battery and a few bits and bobs.

So Power to weight was 24/199 = 0.12 and is now 24/189=0.125 ~ 5% improvement in Power to weight.

Completely unnoticeable to the arse dyno - it's just easier getting it in and out of the shed.

I've been explaining this for decades

OK, this tuning house claim 3.5% (4.6hp) as a huge increase.
Yes I know its about the overall driveability and throttle response, but nobody(except maybe HD owners) gets excited by the driveability on a dyno sheet

If I'd have spunked a grand for 5hp and better driveability, I'd be quite disappointed.

[Ditchfinder]

If you need to spend a grand for 5hp increase you might have bought the wrong bike to begin with....

Arse dyno.

(Probably the one that matters most).

No idea 'why', but the R850RT (238kg) felt a hell of of a lot easier to move than the K100RT (253kg).

Those older K's carried a lot of the weight quite low down cf 'traditional' layouts didn't they?

(Not that it made my K12LT any easier to shuffle about ).

It's definitely not an FZ1, as they had carbs

2006-15 fz1 was fuel injected, but I'll admit I didn't realise the gen1 was still with carbs.

My fz6 rolled around easier than my cbr250, despite being some 50kg heavier. It had me scratching my head, checking tyre pressures and brakes... I think in the end it was just about the higher wider handlebars.

199kgs !!!!! that's only 13 less than my 143bhp CB1000R, which rarely gets all 143 going through the back tyre because it's stupidly fast

Fuel injection + ABS = lardy

Now I wouldn't mind this if it was fueled nicely and the brakes were good...

Don't forget exhaust catalysers.

Mine has a decat pipe now. Saved about 2kg

Should've bought a nice Japanese inline 4

When I replaced the plug ugly and obtrusive cat on the Duke 690 with a decat pipe I must have saved nearly 5kg. That thing weighed a ton. It also made oil changes a nightmare, as the oil had nowhere to go except all over the cat. Horrible piece of design. Replacing it with a link pipe was worth it just for the maintenance aspect.
