Getting back to the engine problem, I don't see how the airbox would cause it unless there's something wrong with the filter or the plumbing inside the airbox.

If you want to run pods without paying big bucks, Uni Filters work well, cost about $15 apiece. Maybe not as cool looking as K&N. Baseline jetting for a KZ1000 with pods and a pipe is 20 pilot, 120 main. That should get you going down the street and then maybe some fine tuning.

No eBay APP ID and/or Cert ID defined in Kunena configurationIf you have room to clamp on a pod filter, then you can install a set of these:

Dave,

I worked out at the track from 1977 to 1982. I worked damn near every position they had out there. I started in the concession stands when I was on 12 years old. Mainly worked in tech and out on the track organizing and directing car where they needed to be for the races. Who knows I may have watched you race 40 years ago!

Small world
Do you remember TOOMA Racing ?? Owner /driver Kevin Tooma
3 man team. ( I was the youngster so I was #3 ) LOL
We had a maroon van and 2 dragbikes. One was a 8 in tire Kosman Chassis, then we stepped up to a 12 in Kosman chassis.
Both bikes and our pit bike were painted my Ralph Pitlock who in on our site as Paintworkz
I got a new scanner and will post some pictures from back in the day.
Milan was our home track and we tested there. . Hey, Do you remember Kevins Dad would show up in a Black 512 Ferrari to watch his son race. That was always a head turner LOL. We won a lot as we were heavily financed , Worked real hard, and had Bill Hahn as a sponsor/ mentor
Enough here . Only went on this long as you brought it up, Now back to your bike. If plugs were going bad that quick it is a combination of to much fuel ( REAL FAT ) and restricted air . I have never seen a bike do what happened to you without being choked off . That said it only happened to me on a honda XR500R while ice racing and freezing up the whole intake system . Your jetting must be real fat and or valve stem seals are shot . A stock air box if filter was clean may be restrictive , but NOT that restrictive
Dave

On a stock rim you could fit what a 130 tire all sucked in right ?
Any of the 120-130/ 18" tires on the market now will spin way before it slip's on the rim.

Now if you got room and want to stay with a spoked 18" rim a 150/60/18 Shinko 006 Podium on a 3 1/2" rim is hands down the stickiest 18" tire you can buy.
I'm about half way through my second one the only reason I'd switch tire is if I did 17" wheel swap to run a Hookup.

With a little more practice and about a 1/2 a million dollars, you could go really fast! Past weekend at Maryland

Bike has been running great! Looking forward to the next race. I think I am going to leave the tire I have on there for one more race. My question today is about running race fuel. I always run premium, but would some high octane race fuel make a difference? Would it hurt anything? I use to go to the sand dunes with my buddies on our 3 wheelers. The guys riding the Honda 350x's said premium was enough, But my ported and polished 250r sure ran better on 110 octane race fuel. Anyone have any experience running race fuel in their KZ?

Been reading a lot about this lately and "most say" to use a lower octane with 9.5 to one with maybe a 89, 91 octane reading even some saying 87 but I'm still not sold on this and 93 oct with 10.5 to one....... the race fuel will hurt performance slightly unless your running 12.5 or 13.5 to one. Goggle it and you'll have plenty to read on the subject.

I found a station that's not to much of a drive for me that sells 91 octane pure gas (ethanol free) on the pure-gas.org website that's suppose to give a little more power but its pretty minor..... but I figure every bit helps

Call Corrigan oil in Brighton MI. They can tell you where near you they have a station selling race gas ( Turbo Blue probably ).
As far as needing it , probably not needed but sure smells good burning .
I use it when racing but I run high boost turbo motor
Dave

Ah yes! I love the smell of high octane fuel on race day! I'm thinking I should just try a tank. I won't at the next race because I want to see if the small changes I made make a difference in my 1/4 mile times. I think my main concern about using it during racing is the motor running hotter.

Went to the track again Saturday. Only managed to get 4 runs in. The first run was a 12.45, tire spun, went a little sideways, off the throttle and then right back on it. Second run I decided to try leaving in second gear and slip the clutch, 13 second run. Third run I decided to leave in first gear but at lower rpms hoping not to spin the tire, 12.03 at 109.1mph! That was more like it. 3 time trials and eliminations started. Lost in the first round. 12.21 at 108mph. I think I got a little excited and had the rpms up to high resulting in tire spin and I have a terrible reaction time, usually in the .3 second range. I do occasionally get lucky with better reaction times.

On a side note, drag racing mini bikes are way cool! I think I might build one.

I've been wanting to go make a few pass but it's just been too damn hot.
When it's a 100 degrees in the shade and we have unshaded staging lane's it's a bitch to sit there in
in full leather's for 5 or 10 mintue's.
