So I replaced my spark plugs recently. Swapped from stock type to the C9EIX Irridium one. However, now when I try any hard acceleration. (Like the ones when you try and wheelie it not when just normally accelerating) I get the bucking bronco effect. It used to just do that at power wheelieng in 3+ but now it does it in first gear as well as when trying to clutch it up. So obviously something's off. Before I put the plugs in I checked and they were .75 with the reccommended being .7-.8 and I'm sure I hooked all the hoses back properly.. Should I have adjusted the TPS as well to accomodate for the change in spark plugs? What else could be causing the bronconess.

(I didn't crazy tighten the air intake clamps on the manifolds as it was a real pain to get to, but they were fairly snug. could that be it?)

im curious myself. I need to change my spark plugs soon and dont wanna run into the same situation as you.

Funny you mention spark plug change issue. I took my down to the frame and changed the sparkplugs and oil last. Put it all back togethor. Now when it starts it revs to redline and keeps on accelerating till it dies or i shut off. Lol. Im assuming mine is a pinched cable or maybe throttle cable according to some friends advice. Will take apart again and redo.
**Sigh, i just want to ride again** :suicide

I used those very same plugs and have had a better bike since. Your bucking bronco effect is most likely do to your TPS. It's probably off now do to the fact that your new plugs are burning fuel better.
To adjust that sensor, search the site for it and you will find ample help. Pictures too! ;)

And my raving revver problems?:biggrin (Sorry, i wanted a cool title with alliteration and some attention too) :burnout
