Hey Gang - I posted my 1/8th times and speed a couple of weeks back when I ran at the strip. Since the bike only had about 250 miles on the new motor I made a conscious effort to shift at 10 grand on each run. Since then I have regularly spun the motor past 10 and it pulls strong all the way up to 11.5 on the tach.
So. here's what I brought to the track (Miss July on the 2006 Kzrider calendar.)
1977 Kz650/810 that has 750 cams, valves, Gpz springs, ported and milled 650 head, WG Mikuni 28's, velocity stacks, 130 rear tire, Dyna ignition, Mac pipe, 14 tooth sprocket (down from the stock 16) I had an irritating flat spot or bogging around the 7 grand range in each gear that probably collectively cost me at least half a second. I pulled around 9 grand in fourth gear crossing the finish line and never got the bike into fifth. My speeds were in the 82-85 mph range and times were 8.9 seconds.
I am very experienced in getting the most out of a bike but this was my first time hammering it through the gears on a track with a Christmas Tree setting me on my way. I learned that launch technique and reaction time can make a whole lot of difference.
Next time around I will have the flat spot dialed out, shift a little higher and know what to expect at the tree. I am very confident that I will get into the high 7's for the eight which is pretty quick for a 30 year old middleweight:)
Oh ya, I gotta add this part....A couple of nights ago I had some fun on the street with my buddy who rides an '88 Katana 600 and he couldn't even come close to me off the line or on a roll.
With my admittedly limited dragstrip experience, my take on your Dad's times are they are pretty close to what I would expect based on the bike's mods.
