Looks exactly like mine looks every time.
Front cylinder looks like its running "rich", (more carbon)
middle one looks perfect.
back one looks "lean"..

Good to know

Thanks skip

you're welcome.
i wish there was a way to make them all run exactly like the middle one,
but I haven't figured that out yet.

Mine looked the same as well.... a long time ago when it was stock.

yeah mine were the same too. just engine layout. tuneboy does individual cylinders iirc

here's a nice pic of pre-carpenter block and all in anyways

If tuneboy will do individual cylinders,
does TuneTCU I wonder?
If so, it might be worth learning all that crap after all.

There is..you want to lean off cylinder1 by say 1%, but enrich 2 & 3 by 1%,heres what you do:

Go into the F tables , go to F1 table & get a calculator. Manually reduce every number by TWO % ie Times by 0.98
yes this takes time.. but it works.
Once you've done that go to the trims table & add +1 to all the table.
Net result F1 is reduced by 1% ( minus 2, +1) 2 & 3 raise by 1%.

I have done this ( actually adjusted 2 of the F tables.. twice as much work, before trim averaging) & the bike ran heaps better.

If 90+% of your riding is in a narrow rev band ( ie cruising) you might only want to adjust the 2-4k revs 5-50% throttle range,( the lazy way to do it)

Next time you wanna check the results, just take the spark plugs out & compare ( way easier than headers) So long as they all look the same, then you know they're close to the balance.

Was this tuneecu or tuneboy?

Appreciate that bones,
might have to try to learn how to do it.
Don't reckon you got, or would make a video showing from start to finish huh?
Where and how to save your previous tune and all that.
Kinda a "beginners guide" or how to do TuneECU for dummies.
heck, I'd buy a dvd of that.
