Exhaust ordered for the Grom. Intake and ECU next I guess. And a head temp gauge.
Zilch, you have any input on ECU's for moterbikes?
Talking about a piggy-back or a standalone?
Bizzaz and Dynojet both work in the same way - modify injector signal to increase fuel. On the Grom they only work at >80% throttle iirc.
piggy-backs. Further reaserch suggested that you are correct for the most part. If you ever go to the power commander and add the WB, it can mod fuel everywhere. It also autotunes on the fly, the bazz will not.
I may have scored a PCV on facebook clasified for 210!

I've often been on the fence on autotune stuff. It's always reactive and the user must cover the entire fueling range to fill in the gaps in the map. That's probably not hard to do on a Grom, but on a bike it's tough to do.
IMO, a properly dunk tuned static map will be better than autotune, assuming you're not running up Pikes Peak when air density becomes a real issue.

agree. pretty sure the grom ecu is Alpha-N anyway.
Right now I'm not sure I'll ever do a bbk or something like that where its needed, I'm more inclined to stay on stock bore, high compression, cam, and maybe headwork down the line.
That said... its nice to know that i can if I want. Also the DJ quickshift kit is waaaayyyyyy less $$ than the bazzaz if i ever want that.

with only 10 HP every tenth counts?
also, you talking to the dude that has 1500 into a minibike.
I have to at least to to equal levels of on the grom.
Track day on the KTM yesterday. Fought rear tire wear issues again Misinterpreted tearing pattern in the tread as cold tear when it was actually hot tear (the Michelin guy got this wrong too). The tire is a dual compound and doesn't show the tear on the harder compound, which makes it look like cold tear. Found out my pressure gauge was inaccurate and reading 3psi high which meant I was running substantially lower pressure than I should have been. that I shortened the life of the tire, but glad I figured it out.
Also, new Hero 5 Black performed flawlessly. Vids coming soon.

by the time you figure out this tire michelin will have another new hotness offering out

I think I've got it sorted. It started to clean up on the last session after adjusting pressures.
I need a full day running at the correct pressures (and a good tire pressure gauge) to confirm my findings.

Thinking of replacing the duke with something else?
I tend to get the itch every 2-3 years on motorcycles.
what I'd replace it with though. I might keep it and get a motard or trackbike
You seem to be trackdaying with some frequency... A dedicated track bike might not be a terrible idea. Last thing you'd want to do is lay the KTM down.

Also high powered twin is super hard on tires. I've done 5 - days so far and already on a second set. Will probably do another day or two before the end of the year.

That's a lot of tarz. I'd look around for a 600 or something to track.
