Wheelies are fun

In uk.rec.motorcycles, SD belched forth and ejected the following:

They still do!

I phoned them just now (well, a few hours ago) and it's 35 quid for a
straight run and 120 for a run with a few tweaks and a custom map.

I'll put the PC on and see how it goes but the bloke did much sucking of
teeth and I could imagine him folding his arms, too ;-) but it might be
worth a punt.

Chicken ;-)

 

They've got a Dynojet 250, so you'll get to see the wonders of the
loop-back system. Fascinating it is.

Oh, you do realise it'll **** your rear tyre good & proper, yes?

I can't wait...

WTF's a loopback system?

;-)

Err.. What, 'cos it'll have so much power that it'll get ripped to
shreads as soon as I open the throttle?

 

Dyno bod sits on bike & holds throttle at position indicated on dyno
screen, starting at say 1/8th. The dyno modifies the drag on the
roller, allowing the bike to slowly rev out to the limit. At every
500rpm(ish) the dyno measures the CO then automatically writes the map
setting for that particular RPM & throttle setting.

Once it gets to max RPM, the dyno increases the roller drag to drop the
bike's revs back down & the display prompts for the next throttle
setting (1/4). The whole process then starts again. Repeat until all
throttle positions have been covered.

The result will be a map containing percentage adjustments for every
throttle position at every RPM. These percentages change the amount of
time the injectors are activated for, which is how the fueling's
adjusted.

The 'loopback' part refers to the dyno being able to adjust the bike's
RPM by modifying the drag on the roller. At least that's the story I
got from the hairy monsters at Dynotech.

Err... not quite. More because the back will be strapped down hard
forcing the soft tyre against the hard, abrasive roller. It'll get very
squared off.

This post was brought to you after less than one cup of coffee, so E&OE.

Fascinating. I thought there was at least some technical expertise
involved but actually, it's just a bloke caning **** out of my bike and
does ****-all apart from importing a computer generated map.

Hmm.. Not a huge problem. I was going to replace them soon anyway - Not
because they're wearing out but because they don't get sticky unless
driven to the ragged edge.

I'm not sure Azara 3s will suit it but they get noticeably tacky after
just a few short miles at a relatively slow (80mph or so) speed.

I'm with you there, man. I'm more a tea drinker which reminds me..
