Now watch my stuff scatter parts the next time I crank it up. And that would  serve me right for judging my friends. Lol

Nah, Frank. Pretty sure you know the difference between a "tap" and a "knock".  ;)

I had an early 73 Z1 that developed a "knock" after installing a Yoshimura big bore kit.  ???
Turned out to be a wristpin seized in a rod and it was warbling out the piston.  :(
Ultimately a very good thing in that one of my cousin's father-in-law was a highly skilled machinist.
After watching him bush that rod on a Bridgeport mill, I could barely breathe until I became a machinist.  ;D

I guess my point is that I am expecting a Phoenix to rise from the ashes!  ;)  8)

You'd still be well-respected even if it did.

Guy's,  it's ok with me what's been said and written.  Frank's still the man. Without him, I'd be chasing 10's still. Then only used parts in that engine build were the RC lightened and balanced crank, which Jay himself rebalanced.  The other used parts were the pistons,  old RC 12.5 to 1. Hey, Mike,  I think I learned about old #$%*!! Let's all go forward,  and see more participants next year,  thanks to all who helped, Bill

Could have happened to anybody, just ask Cory Hogan. We do our best with what we got and let the chips fall where they may. Happily we are able to dust ourselves off and keep going!  8)

Guys,

Not getting into the middle of this, but have one thing to add.  Bill, just some advise from someone who learned it the hard way, and I am not pointing my finger at you, this is for everybodys enlightenment.  When I first bought my KZ, it had a 1397cc engine. That engine blew up at the Atlanta Night of Fire that year.  We traced it to the fact that the engine was assembled with LIGHT WEIGHT wrist pins.  I mean these things were thin! :o The wrist pin broke, side loaded the rod, snapped the small end off and all hell broke loose.  Took out the cylinder, head, clutch, cases. input shaft, and put divots in the frame.  You can come over and look at the frame, still there.  Oiled down the track, right boot and pant leg, lucky it didn't get under the tire.  Wrist pins are not the place to save weight, not that it was your plan.  It just won't work and the engine won't be any slower with heavy duty pins.  Wrist pins can flex, something nobody wants.  I have big ole honker pins in that thing now and haven't changed them in 10 years.  My 2 cents, and sorry to see the carnage.  You'll be back, better than ever!
I'm not as smart as I look, but I am pretty.

The whole point of this discussion on my part is this; if you suspect something could be amiss in your engine, please don't dismiss or ignore it. The signs, no matter how subtle, show themselves to us long before we have catastrophic failure. It doesn't matter if its a street bike or dragbike, mechanical issues are like the aches and pains in our bodies. Its a dull, far off feeling at first but eventually, and if we don't address the root cause, the sharps pains will eventually hit us like a ton of bricks.

My post was not to belittle Bill, but to give him a little hell cause he knew something was going on and still he pushed the limits and got caught. He could have been hurt or even killed for ignoring the obvious, but he was saved by a higher power- this is one thing none of us should ever take lightly.  He had already set the MPH record so he achieved his goal for the weekend.  If I thought Bill was sensitive about this issue, I wouldn't be calling him out in public. If you notice one thing about Bill and I, when we f'up, we don't keep it to ourselves to save face. We share it with our fellow forum members in hopes that our experiences will one day help another person to avoid of mistakes and save a ton of $$$. Or even a life!!!!!!

Love ya Bill!!!!!!!!!!!

I, for one, would still like to know what failed first. Bill, did the RC pistons use clips or buttons to retain the pins?

Frank,  you are and will always be my team mate and friend. I heard sumpin and should not have ignored it. But I knew the bottom end,big end wasn't the noise,  but like a dummy I went on, the man upstairs was looking out for me and I know it or I wouldn't be typing this.

I love this sport and the people,  for four days I ain't thought about jack but racing!  Frank you can give me #$%* anytime cause you care and I know you not only help me and  many others. Thanks and I appreciate your help, patience and advice,  ....now enjoy your ET record. ...til April,  lol, Bill  ;D

All racers : Like every motorcycle drag racer we all want that win light ON our side off the track at the end of 1320'. This year in 2016 I watched my friend and fellow racer of 20 years leave the line and 17' into the run he went DOWN HARD me and another firefighter used all of our learned skills to kept him alive but 26 days later he went to the big drag race in the sky [ passed  from a blood clot ]...... he was 40 years old, and 5 kids lost their dad and a friend. I made a plaque with his nick name BUBBA on it and wired it into the fence beside lane 6 the motorcycle staging lane at NTR so US the two wheel racers can look over and THINK = THE LOVE OF THIS GAME IS NOT WORTH OUR LIFE, right Cory Hogan....... be safe as FATHER FRANK is watching over and listening for us all and him riding 3 bikes in 4 classes plus all the many bikes he works on at the track. Frank Bless you and your wife as you folks are the reason I cannot walk away from this sport.

This was definitely a memorable outing. If you aren't ready to race, spectating is a blast too. I spectated at these events for almost three years before I started to compete. Enjoyed them all so far!  8)
