Question about classes.

[chillin]

I have a 2000 Kawi ZX12r 100% street bike with standard fairing and wheels.  We have a 1198cc stock engine, clutch and tran with CP high compression pistons, valves, rings and springs and a power commander 3 fuel management system.  I don't yet have a rules book but I am wondering if anyone can suggest what class I might be looking at.  I am also 100 new to this if you cant tell.  Not new to going fast (197 before the mods) but new to actual timed off street racing.  Thanks in advance for any info you may have.

Chill, get a rulebook, now that that is out of the way, the LTA uses the same rules and they are on line.  To help classify your scooter more data is required.  Production means looks like stock, all mods out of view.  If you have a pipe or any non stock looking parts, then modified.  Speed is addictive

Displacement puts you in 1350cc engine class.   Assumping you run an after market pipe, you would be in MPS/G 1350 ... As all Ohio records are open records, I would expect this one to be north of 210 after the April meet.

[chillin]

Looks like 220.553,   I'm going to have to get a book.  I've been 197 bone stock on a country road and after the mods I think 210 is doable but 220+  I think a bore job might be in order next year.  We'll see.  Maybe it will be something a little south of 220.  At least that would give me a fighting chance.

[55chevr]

All Ohio records are open as no one has made a run there yet.  That said, I wouldn't count on accuracy of factory speedo.  GPS might be a more accurate measurement.

Chillin, with all due respect -- I think Joe's right -- that you are looking at a readout from the factory speedometer.  Having raced a 2000 ZX12R -- and having invested in some engine work ( ) I will confidently guarantee that you aren't seeing 197 honest-to-goodness miles per hour with a "bone stock" Zx12R.  I don't mean to sound rude -- but rather realistic.  Don't let us keep you from having fun, though. . .

Though the bikes may behave differently ( and I have absolutely zero experience there) the miles that sort of fly by on a "country road" getting up to speed may give a false impression of what you can do in the Maxton/Wilmington etc 1 mile drag race. I distinctly remember a meet with someone saying "man, been 130 in my ride on the street. Records here I come," and barely get to 115 at the mile. He might have spent a couple of miles ooching up to the 115-120 range and then topped out at the 130 (factory speedo as SSS points out) number down the road.  More like Bonneville runs. That said, bring it on! Have fun, be safe.

You're probably right and I have had this discussion before (factory indicated speed vs. real).  I know we had her to 192 in fifth on the dyno and the speedo was only off by 5ish.  The nice thing is I will have a real indication of what she can do this spring, we have a little track here in MN (BIR) with a real nice 1 mile straight away on a 3.1 mile course.

Most bike speedometers are 10-15% off on the far side of 100mph. A GPS device is pretty close (even a hand held model like the E-Trek). Given that bike speedos are based on engine monitors and gear ratios, they aren't based on actual movement of the bike itself. Even GPS data can be misleading. The speed through the timing traps may not be the top speed reached while getting there. I've also wondered if there might be a bit of wheel spin with such a small contact patch.

OK guys, I have been reading the 2012 rule book and first I would like to settle on what class my bike actually fits in. It is 2300cc all OEM except for the supercharger kit and the 3-1 after market exhaust. I will be running her naked no streamlining (Not even the sports/flyscreen shown on her). (Will need to know whether the hump in the leather suit is counted as stream lining or not. If so, I will be getting a suit with either removable hump or no hump at all.) Only other change is I had a rear rim enlarged to 18-inch diameter so I could get higher speed rated tires and a larger variety.  I do have combination radiator intercooler but it is not on the bike at this time because I lowered the boost so the compressed air is not heated as much. Not sure if that matters anyway.

I run premium pump gas  and sometimes if I am worried about the quality of the gas I add a little octane booster. If the gas sold at the track is good I will not need and octane booster. I want to run in the gas division. Not sure what type of gas they sell there or the octane and quality?

Here is a picture of the beast I will be taking the removable hard bags off. frame mounts to if needed. Also I will remove the passenger floor boards. But could not figure out from the rule book if I can leave the OEM driver floor boards on or not (I want to leave them)







My objective when I built the bike was to keep it as a street bike and now have over 60,000 miles on her. she is a good cruiser 
A fast powerfull cruiser but still a cruiser 

Thanks for your help and suggestions

the exhaust and rim will put you in modified.
there is good event gas and running that will keep you in the gas class

[saltwheels262]

you want to run it ECTA.

frame class-  m/bg . octane booster would put you in the fuel class. (m/bf)
engine class-3000/4 .    3000 cc, 4 cycle .

you should be able to keep the driver floorboards.

[saltwheels262]

the blower would also get you out of production class.

I should write the answers down on paper with these multiple question deals. if I leave the reply screen and then go back to it, a lot of times it's blank.

I believe I read somewhere they have 100-octane unleaded at the track along with leaded gas of higher octanes and Rocket is the brand. If I'm wrong on this, someone please correct me, but the aero hump on the back of the suit is not considered streamlining. Streamlining is anything FORWARD of the rider that has the "apparent effect of directing, limiting, or controlling airflow around the motorcycle or rider." In Modified we are allowed to run a streamlined tail section as described at the bottom of page 85 as it is BEHIND the rider. Again, if I'm wrong on any of these points, someone please correct me.

[Seldom Seen Slim]

Aero hump on the jacket of the leather suit IS repeat IS streamlining at SCTA events.  I don't know if the ECTA rules include that interpretation, but I've had the discussion with the tech guys and interpreters enough to know - no aero hump is allowed in naked bike classes at Bville.  I'll take a look through the rulebook and see if I can find it on paper.

Of course -- maybe the rules are different now - I had the issue about 5 or 7 years ago.
