Will be taking the bike to dyno, what to expect?

So, this weekend I plan to take the bike to Dynotunes in Burlington. Since I've never had a bike on the dyno before, I am sitting here at work bored to death and wondering what to expect.

I plan to do the "Horsepower verification testing" that is listed for 80 bucks, but I wonder---apart from graphs for torque and HP, what else will I get? Will I get a reading for how far off in % my speedometer is, and other things like that.

Well, if anyone can shed some light, great! If not, I'll let you know after I do the dyno myself :)
 
That sounds like $80 chucked away unless you want to spend a bit more and get a proper map put in. I was looking to take my bike to a dyno but it was going to cost me around $300 to get a map put in for my slip on with my power commander. The HP readings from one dyno to the next don't usually compare but they are useful for getting maps done.

Meh..that's fine, I'm not planning to put a PC for now.. Yoshi slip-on and k&n filter don't need a PCIII i think.. power commander would make sense for me if I go with a full exhaust later I guess..
 
DONT put on a K&N...stay with stock

Dont buy power commander....just flash the ECU....waste o money

expect to be dissapointed.....HP is always lower than you think.....I took my bike to 6 different dynos.....every one was different....but I'm in a good ball park

I would be interested in your speedo error.....

I have never had a speedo error on a dyno....only GPS's are out..

have him doit at 60, 100, 120, 160....see what you get

Yeah, my main goal is to see if I'm in the ballpark, don't really care about precise readout. As for the speedo error---ever since I got my gsxr 1000, I haven't figured out where to mount my GPS. That was so easy on the FZ6, had a RAM-mount and all....
 
What to expect?.....Your motor could blow up!
 
Well some CF exhaust have been known to melt or distort while on the dyno. I know Leo Vince and 2 Brothers both state this in their instructions as "not to be used on a dynometer".

The most important thing you get, is your AFR reading! I had done a lot of mods to my engine (slide stops, +4 ignition advance, velocity stacks, etc.) and wasn't sure how my bike was running, seemed a little boggy down low, OK, up top. Yep, that's what the dyno told me:

This was done on one of their "dyno days" so it was quick on, quick off, that's why there's no RPM or Torque readings, they didn't hook up to the bike's plug wires to get the RPM reading (I assume that's how they do it).

My bike was the most powerful 600 dyno'd all day :)

What it told me? I needed AutoTune :) Bike pulls like a freight train down low now! I'll plunk the $80 on a re-dyno and verify everything is rock solid 13.2-13 now :D

After I had my bike dyno'd I noticed little hairline cracks in my Two Brothers carbon fiber pipe (and that was only two pulls on the dyno!). I called the place where I bought it (it's only a few months old) and they refereed me to Two Brothers who says:

"Two Brothers Carbon Fiber Mufflers: Always make sure the fiberglass
packing inside is in good condition and not burned out, as exhaust heat
inside an empty canister will deteriorate the carbon fiber sleeve. TBR
sells repack kits (part # 005-10038) that include new rivets and the right
size drill bit, making it easy to do yourself.

Also, NEVER dyno test your bike with carbon fiber mufflers installed-
the intense heat and lack of cooling air can quickly cause the
CF material to burn. Two Brothers Racing does not provide a warranty
for burned carbon fiber."

The bold and large print was NOT added by me, it's right in the install instructions!

Great I didn't want to shell out 100 extra for the carbon-fiber, got the stainless-steel Yoshi instead :) No melting of that baby I suppose!

Good choice! Stainless won't ever melt, Ti and Carbon can ;)

I'm getting my bike re-dyno'd on Sat, and my GF's too "after the flash" :)

Did you e-mail Bruce@dynotunes.ca and let him know you're coming on Sat? They get pretty busy so it's nice if they pencil you in their schedule ;)

See ya there! And I might be getting the equipment to flash your ECU shortly Corsara, not sure if it goes right back to 2003 but I'll check for ya :)

I like what I hear :)

I'll email Bruce now, hope it's not too late.

lol, 2003 Gixxer 1k is on the list! Not the 600 or 750, but the 1000 is :) I'll put you on the "wants more info" list for when the equipment gets here.
