Rear tire chirps on deceleration

[desert_max]

I'm not sure I would consider most of them "more powerful" bikes lol. Great bikes but not more umph.

I’m glad you said it, Sean. There are a lot of more powerful bikes ... or equivalents, but that list is a group of also-rans. Sorry, but pretty much the case. And I think we’re talking brute torque to the ground here .

Same here.

I was thinking about my beloved '94 ZX11.

Not a day goes by I don't think about that bike. (Also, never chirped a tire on it. Amazing what simple throttle control can do.)

Power Commander is the issue.

Just FYI, The Gen 1's dont have a power commander. Typically the power commander controls fuel on a fuel injected bike, and also timing as well. These bikes are carb'd.

Is it possible that you have an aftermarket ecu, like an ignitech or dynojet? These will control timing only (well the ignitech can control a lot of things, including Vboost, and the kill portion of a quick shifter).

Yeah it's ignitech, I don't actually like how low the Vboost kicks in with it tho?

You mis-spoke here, Dynojet doesn't manufacture a Gen. 1 VMax ignition box, it's DYNA who does.

You can set it where you wish.

Interesting, a part of me is glad that I bought a bike that has mods on it already as far as price point. But sometimes I wish I had found one more stock, and done some of the mods myself to learn with it.

I do, because the rest of my collection is comprised of xj700 airheads, xj750 maxims, xj750 secas, xj650 maxims, xj650 maxims, xj650 secas, xj550 maxims, xj550 secas, and xs400rj secas.

How low does it kick in? Stock is 6K when it starts. On some of the ignitech maps, its set at 5K. If you have a T-boost switch, it could be set at 3K.

Some of the Ignitech units DONT have the additional pigtail, so you can have an ignitech and still be running the stock Vboost set up.

True. This is what I get for multitasking this morning....Dyna is for the Gen1's, Dynojet does the Power Commanders.

I guess I should've added "lol".

You interested in another XJ900 Seca and an XJ750 Seca? I'm keeping my XJ650LK but don't need these others.

Yeah it kicks in at 3K, pulling real hard by 3.5K. I feel like closer to 5K would be the magic number.

Just got back from a long & awesome solo ride through some scenic twisties. I have a feeling it might be a late night in the garage tearing into the bike a bit and learning more about it

That's absolutely ridiculous.

You're not moving enough air to get any benefit out of Vboost at 3,000 RPM whatsoever. Set it back to 5,000 at least.

Take off the left scoop and look for the round plug. If the plug goes to the ignitech, then it would depend on what the Vboost tab is set at (In the ignitech map). If it goes to black box that is mounted on the left side as well (I think its 3X3 roughly), then its the stock set up.

The T-boost crowd doesn't consider it ridiculous. Nor the Stage 7 crowd.

Then they obviously don't realize that when you're not moving that much air that having a bigger intake runner really does nothing for you.

But that's why some people put a tunnel ram on a stock 305 with a factory cam in it.

Yeah I'm not sure what v boost setting I'm into being as the bike is so new to me, but it is ridiculously fast for a cruiser style bike. I actually drag raced my brother in his Corvette and beat him pretty good. At that moment I was like holy crap this thing is an absolutely monster!

 

[Parminio]

You can do that on a stock Vmax.
