Sorry if I sound like an idiot in advance. If you install an Ivan's TRE or similar product which advances your ignition timing, will have any negative affects on your engine? I'm thinking of getting one and installing it but I want to know it's cons.

I don't have, or want, one, so I could be mistaken, but a TRE doesn't advance your timing, it simply stops it from being retarded by the computer at the top of in 6th gear by always telling the computer the bike is in 5th. To keep the bike under 186 mph (or whatever) the computer reads the engine and when it's in 6th gear at whatever RPM would equal 186 mph, it retards the timing so the engine stops developing more power. By telling the computer that the bike is in 5th, the conditions are never met for the computer to retard the timing.

Again, I could be wrong, but I think that's the gist of it.

 

[sqchram]

I just insert the key, turn it to on, hold in the clutch and press the ignition - the timing just comes naturally.


heh - jk, user name said it.

If its an Ivan's product it is solid.

BTW, I believe the ECU typically has different fuel maps optimized for different gears, and by always telling the ECU the engine is in 5th, it always uses that map which, to me, is a major con as far as pros and cons go. Maybe the newer TRE's are smarter and leave things alone until 6th gear, but still, I don't think they have any real benefit besides allowing you to exceed 186 mph, which is of dubious utility in reality.

To me, things like TRE's and Power Commanders are useless. If I was going to put money into my bikes, it'd be in the brakes or suspension - improvements that I could actually use on the street, as opposed to squeezing an extra 5 or 10 hp out of an engine that already makes far more than I could ever realistically use.

But it's your bike, so...

The Ivan's TRE basically just improves throttle response in the first 1/2 turn of throttle in gears 1 through 4.

I disagree. Power Commanders exist to optimize the fueling all across the rpm range, not just at the peak. That means, it'll help out in street riding rpm levels as well as top end power.

Case in point, my father installed a full Akrapovic system on his Honda Blackbird. After having it tuned with the Power Commander, his midrange jumped 10 lb-ft over a wide rpm range. Now THAT you can feel and is incredibly useful for roll-on passing maneuvers, etc.

I have no doubt they make a difference, I just question how useful an extra 10 ft lbs really are on a bike with already upwards of 100 ft lbs in the first place. No sport bike should have any trouble passing other vehicles on the road. Engine performance is already so high stock that increasing it further is really just for bragging rights.

That same money put into getting the suspension set up for the rider's individual weight and riding characteristics would be of much greater utility.

Or if you just want more power! :banana

Not trying to pick a fight or be an asshole, but I kind of use your logic, against large displacement motorcycles. Why buy a Hayabusa, when I won't use the 600cc to its full capability?

On the other hand, I've been thinking, and I should've put my $$$ on a set of light wheels, rather than an exhaust and power commander...

Like tits on a boar right??

But hey, if ya love boar tits like I do, well....

A 600cc inline 4 has more power than I can fully use, I admit that. However I like the effortless acceleration and torque of the larger bikes. I am over the racing on public highways at insane speeds stage of my life. That's why I have a ZX-14 and my GSXR-750 is for sale. It doesn't handle very well but it's great for cruising slightly over the speed limit. I'm thinking of a TRE because I read somewhere it adds 10% horsepower and torque. I know I don't NEED the power, but it would be nice for only $200. Basically, I love boar tits. My bike has been set up for my weight already by my mechanic. Upgrades for my suspension is out of my price range. I'm not interested in doing 186+ MPH. Thank you for all your responses guys, but nobody told me if it can damage your engine. Anybody know?

I've never heard or read anything about them causing engine damage. A friend of mine had one on his liter bike and never had any problems, and he beat the shit out of that bike.

^ no more than riding in 5th gear, take a look at the link in my sig for a good manuf. of TRE, not sure if for Kawa tho. jimphunpants - ha ha so coy, hey you're in OK, are you a McVeigh?

 

[Guitar Man]

Just keep it in the lower gears if you want more power. Works for me. When I kick mine down to 3rd doing 70mph I can pass anything. That sucker will get down and move. I shiver to think of how it would feel to do that on a liter bike.

And by the same token, for MOST riders, the stock suspension is just fine if they take the time to fiddle with it themselves and get it adjusted to their weight. Most sportbikes for most people on most street rides should handle just fine with the stock suspension personally adjusted, so why throw money there? Not everybody needs some top-shelf boingers on their bike...

Using my example, he likes that extra midrange cause he likes riding the huge torque curve of the larger displacement hypersport bikes. It's a Blackbird. It's not meant to carve corners like a 600, so he spent money to focus on the area he most enjoys from that bike.

Modifying a motorcycle is an incredibly personal thing, so what may seem pointless to some is quite important to others.

Timothy McVeigh is actually from western NY, less than 10 minutes from my parents house. Went to the same high school and everything.

Because more power = FAT GUY will actually go somewhere. And yes I am speaking from experience.
