Funny, I ran a snowmobile in my 3rd run, when I got back to the staging lanes a couple of guys commented on how I was brave to run the snowmobile. they told me they often see them cross the center line.

Yes you can wheelie big KZ. Wrap it up to 6 or 8 thousand rpm and dump the clutch on a sticky track and look out. That was one of my other experiences out there. I handled it pretty good though, just pulled in the clutch a tad and down went the front end with out losing much speed.

Kawtoy, your bike is running in the range I want to eventually get mine. Would mind telling me what kind of mods you have?

Yes sir....there are some racers on here somewhere. I mainly race the brown bike which has been as fast as 11:40's but mainly high 11's (slow it down some to be consistent) and the blue turbo has been 9.83/143 mph on only trip to track. Low boost and not using nitrous yet, so could be LOW nines...possible in the 8's? Working on a 1400cc bike now that will be stretched with goodies hoping for nines on just motor, but will see if I can make it...that's the goal...a street Z that runs nines any time. I WILL get there!

I think you were refering to ZR1 Rider. I have not run my bike yet but will be making my first run in a few weeks. I have lots fo mods but they really are not worth mentioning untill I get some times slips to back them up.

It's been a few years since I took my 1000 to the track. Best time was 12.78 @ 104mph. I was going through the traps in 3rd :S . I then decided to put a wider tire on the back for better traction since the 110 was spinning and have yet to get back on it.

I've raced my Ducati M750 Monster and went 13.1 @92 with somewhere around 70HP. That's with no Tach and a 56" WB.

BTW, the pic I attached it the same bike that's BOTM but before I did the work to it. It's pictured exactly how I last raced it.

Later, Doug

Most of the stuff I did don't cost much, just some time. Did most of this stuff over the years, I've had it for 27 years now.

removed center stand
made lighter rear brake stay
tossed the tubes and rim locks
advanced timing to 36* total (including the advancer)
port matched the intake rubbers (at the carb & head)
made a foam air cleaner for stock airbox
removed the screens in the airbox
Barrnet clutch kit
35 tooth rear sprocket (stock is 33)
header
120-90 ME99a rear tire
1105cc kit
bike now is 545 pounds with 1/2 tank of fuel, shes a heavy ol turd! lost around 20lb. from stock
practice, practice, practice. I found the quickest way out of the hole is to leave at around 7000 rpm and let the cluth out in a "quick slip", not just dumping it. I have the clutch all in by about 30' off the line. 60' times are in the 1.7 and 1.8 range, lifting the front wheel makes for cool pitures but are always my slowest ETs. Slipping the clutch like this has broken a friction plate once,(about 1/3 of it in the pan) never noticed till I was doing top gear roll ons against the kid's CBR900, got a little slip at 4000, hooked up again by 6000 or so.

I never could make a engine ever run good, so I'd be embarassed with my racing times. Here's a friend of mine, Rick Horn back in 1981 when class racing was hot in motorcycles. This was a D/modified turbo class. Works kind of like the NHRA stock/supersock classes sill running on a weight to CC structure. This bike ran a 8.78 @158 out in Fremont,CA
Sorry picture not so great, but a great old Z1.

Here's a friend back in East Haddam, CT back in 1982. This one ran low 9s without a turbo. Times were great back then.

I've never raced. Well, except to dust an occaisional Hardley between traffic lights.
Trout, I think you're getting great times for a 30 yr-old stock KZ1000! Sounds like you know how to launch that thing!

Hey LTDRider! Thanks for the praise. I've still got work to do. Talk with an old drag racer and he gave me some tips. I think one thing I nned to do is shift sooner. I am hitting 9000-9500 rpms before shifting. He was telling me shift just before red line (8500rpm?). I've got the bug to go faster. I think I could get a tenth of a second just through practice. It is very cool being out there on my old KZ. I had 3 guys within my first half an hour there ask to buy it. I was the only OLD iron out there. Kind of felt like I was in a class by myself. I definitely got a lot of looks. Most of the bikes racing out there were crotch rockets with a couple of harleys.
