It does, it follows the the gain in power to fuel percentage.
This could/may mean if youre at the rich part of the fuel sweetspot its still ok.
In any case its very little that needs attending to.

I usually tune engines to be at the richest possible mode while no loss, lets say you are here, just open it up and dont think again, if that helps.

Hey great belgy!
What I do is to get an even afr level and then I push it up and down to find best power, its not always where its supposed to be, my pony here likes leaner than what Im used to. What it likes it gets
As you may have guessed I have my own dyno, makes it a lot more direct, Ill try and help as much as I can for any users trying to sort their bikes fueling, just ask. Not selling anything its just for fun.
More info later this spring/summer when my 570 riding buddy comes here and we dyno that OEM bike, this will shed some useful info.
Thanks from tourist

Yep, np! Bazzaz is a tiny different to PC as it will always show whats in the unit.

Bazzaz map for oem exhaust, ported head and CP piston.
Makes for a flat 13:1 AFR.


And current result in a Dynojet 250 dyno SAE corrected, the wide range is what i like the most, quite handy in the shorter straights.
With metric hp and STD correction its 65,6 hp, you need to look carefully how graphs are diplayed, I prefer emperial hp and SAE correction factor, after all its just your percent gained that makes the bike faster.

Interesting to see!!

Trivial q - are the +/- numbers in meaningful units? or just context-dependent "bazzaz control steps"?

It would be percent, it responds that way but I dont really know

And a pic of the seat, dont worry I wont quit my day job for this, just yet
Some kind of mesh on there would be purdy.

Miss Berg as she stands now, its nothing of a showstopper, but I like the sleeper note to it.




The studs we use



And a clip of how fun its to ride the ice track, on my now retired crf450 RIP.

Thanks from bushmechanic

Ain't nothing wrong with a sleeper! I like the silver/blue wheel combo. Brutal and functional. Still such an elegant bike design. That's an 09?

What sort of studs are they? Pre-studded tires or put in afterwards? And what tires are they? - And would you say the studs are exclusively responsible for grip in your purpose, or is it affected by the tire compound as well?

I've been commuting / trailriding on my DR-Z during the past couple of winters, had car studs put in Trelleborg Army Special a.k.a. Mitas XT-644. Works amazingly well. Goes just about everywhere, although in more of a "can get you across the occasional ice" fashion rather than any racing being possible. The car studs even stay in and stay unmangled over long pavement rides!
