you are correct on the whole enertia deal.....but all a lightened flywheel does is help the crank rotate faster. so you are correct in a sense..... if your flywheel rotates faster that means you can rev faster. it does not make your car have higher gearing or whatnot. sure you have less mass to rotate...so that jus means that you will get to that rpm quicker...not have a higher rpm at the same speed.

what i meant about stinky clutch...is just that. if it smelled like brakes. brakes and clutches are lined by the same metarial so if you burnt your clutch during that race where you missed second (and probaly drooped the clutch high for the launch) that might have caused the higher rpm right after. also...do you keep your foot on the clutch while driving on the highway? just a thought.

a bad o2 would not cause your rpms to be higher

just another thought....do you have a vafc? a friend of mine had some wires hooked up wrong and i rode with him. he raced it but it never sounded like it was going that high in rpms eventhough he was shifting at the so called 8,500. in reality he was shifting at 4,000 after he found it what was wrong with the wirining of the vafc.

the only thing i can say....is pay more attention. you should be able to "hear" the cars rpms by now. if your driving....dont look at your tach and try to guess at what rpm your at. now with this knowledge....go back to driving your car at the highway....does it really sound like it is at 5,200?? or do you think it sounds like it is at 4,000? honda tachs are very good compared to other manufacturers. i would assume you will find out that this is a wiring problem and nothing mechanical. just py more attention....you will also become a better driver when you can just glance at the gauges and not read or study them
