Stuck throttle ?  Sudden death ? Hill climb champion ? Drag race winner ?

Chasing the original adrenaline? :lol:

but really, in my case, it's more like overheating and a lack of power...

Sorry, was in a rush when I posted. I just am curious as to extended WOT. I want to drag some buddies on their XR680R's when I go to Goler this week. I already went to 15 tooth front, but I think the 48 rear is too low. Also, I did a top end with goodies, and wonder how these beasts take WOT runs?

WOT with stock jetting? You can safely fall asleep with your wrist WO and drive all day without blowing up your bike. (as long as you have a nice clean air filter) :)

Wide open runs may require a bigger main jet. I am sure Stewart has this figured out. :-) Pull second off the line and sit as close to the gas cap as possible, face by the number plate. No way those guys will hang. BDI probably has some good drag set-up, judging by the pics and replys.

Doesn't matter, when the g-forces fall off, shift, hammer it. You'll be too busy with hangin' on and focusing to worry about hitting the limiter. the k5 chews up straight line runs.

Cool. I'm running 15/48 now, it didn't even blink at the taller gearing. Would a smaller rear sprocket be good for dragging, or is there a point at which the engine starts to struggle with gearing? I kinda doubt it...

Taller gearing only comes into play at high speed.  Then the air friction can become so great that the bike will not pull full RPM in 5th.  That is why they invented fairings and V-engine road race bikes (narrower). Cam.

We're running 15/37 pulling 2nd gear hole shots , take it up too about half throttle and slide the clutch just bit you'll leave the 4bangers suckin dust. For extended WOF just make sure you're fat enough on the main jet-no white plugs.

I agree. Out on the lake ice, you get a good opportunity to feel exactly how much "gear" a KX500 can pull before you effectively "govern" the rpm's and speed. I was able to pull a max gearing of 15/42 before I felt the rpm's flatten out and not gain any more speed. Remember the KX500's tranny uses overdriven gears in BOTH 4th, and 5th.
