Timing and powerbamd

I’m sensing there are some skeptics in the crowd??? :ohmy: :ohmy:

It's gotta alot coming down to sec. at 65 or 75mph, then at 90 in third is right on the power band. So in other words it blasts itself through these speeds very quickly, it's got to be moving pretty good. I used to get left in second, and thats where their distance was gained. In third it'd lock the bikes together... too late. Now I have a much stronger second. It extends higher too. And the torque it generates just before shift is a good booster for when when third comes in. Third is right there in the middle upper end of the band. It pulls stronger than before and extends higher. I learned you have to be in a gear for as long as possible and not be falling behind. It's when I shift that the distance is gained or stablized. Now I've got a chance to use this new torque to see if I can hang. I can ring it all out and see. I might have to advance the timing who knows. But I'm testing the high end first then when I do hit the wall, I'm modding something else! If more clinder pressure is not a help then gas, well :blink: Have to read some more. I figure I must have done somethig right since I can be in a lower gear and BYE :woohoo:

What bike is this? 100mph in second? Street Z? :dry:

What color is the power band?? I have a purple one in my bike but I don't think it has enough Marsilvain tension to prevent side fumbling of the lunar wainshaft because my 1000 will only do 85mph in second at 13,000rpm.

Nads...

What gear (sprocket tooth counts) ratio are you running?

I would think @ 100mph in second gear this thing must be screaming & whining "Shift me damn it" something fierce.... :S

Otto's probably got some "powerband-in-a-can" that should do the trick for ya

If you want your motorcycle to go really, really fast, just pour 17oz into your gas tank. Of course that means you'll have less room for gasoline but that won't matter cause the rocket juice is really where it's at and who really cares about octane anyway when you have the good juice that jolts the pistons like they're a naked fat lady on roller skates on her way to the burger stand for some fries and greasy meat but her ankles are too weak to hold her fat legs steady on the little skate wheels. Not that it matters much what the fat burger chomping lady had for lunch 'cause with the new rocket juice in your rod you can pick up some way hotter chicks anyway that love to ride on juice powered bikes because the new powerband really get's 'em moist where it matters most and if she's got a sister you might get yourslef twice the fun for the price of one and that leaves more money for more powerband juice if you're getting the picture....WHEW!!!

Ha-Ha-Ha Laurence, you'r real funny. I love you too. :kiss: :laugh: No, no powerband in a can. :S

100mph in second gear? You sure you don't have the sprockets on backwards? Maybe the speedometer was indicating kph? Got a tractor tire installed in the rear? Is that a V-twin? You might want to take a look at where that rear cylinder is pointing 'cuz that the direction it's going when the rod gets thrown.

Stock timing marks are just like stock spark plugs or stock valve timing. They are a compromise to give you the best all around experience as the manufacturer defines it for you.

There are so many variables affecting where the optimum timing should be including engine temperature, engine speed, engine load, volumetric efficiency, type and quality of fuel, etc. with the answer to the equation being that the fuel should be fully burned at about 20 degress ATDC.

Non-computerized ignition systems without vacuum advance ONLY use engine speed to determine optimum timing. Add a vacuum advance and you get another variable taken care of (in a "best guess" kind of way). Throttle position sensor takes care of another. Knock, oxygen, and MAF sensors take care of other variables. Is it any wonder that todays computerized engines can deliver more power with better fuel mileage and reduced emissions over a wider range of driving styles? All of those sensors combine just to determine optimum fuel delivery and...spark advance.

OK- I just found by readout for my bike. GPz1150 .420 cams.
I have a final ratio of 2.22:1 (18/40 sprockets). I can attest that i have to slip the clutch like crazy and rev the engine from a dead stop to role. I believe I have more than normal HP in the bike. In first gear at 9K I am doing 66mph. In second gear at 9k I am doing 96mph. third gear I can do 101mph at 7.4k and 123mph at 9k. These are measured with a GPS. I find that my speedo is only a little off, and my tach is electronic, taken off the coils. I would have to be turning 13.55k to be going 100mph in first and 9.4k in second to be going 100mph. I think that he might be going 100KPH in first turning over 10k. And, since when dose "retarding" your ignition give you more power at top end????

Damn. Your second gear ratio is about the same as my fourth!!! But...it is a much smaller engine.

Here is the full readout for my gears, as they stand at this time. I also have a second ratio all set up and mounded on a spare hub of 16:45 (2.81:1) I did that so I can use the same chain and do a quick change if challenged by some shmo to a race. I already have the rear sprocket mounted on a spare hub that i bought on eBay. this way I can do the whole swap in under an hour.

otakar,


Thanks for sharing the print out.

Can I ask what pitch chain you running?

Thanks,

Buzz

Where do you ride that you want such a gear ratio? Looks like going for a new top speed record is in your grasp, 160mph, that's still below those new performance bikes. Also how's the handling at that speed with your suspension set up?
Man I thought 140mph in a car was pretty fast, when those corners just seem to come up so quick!

Here is the link to the build. Look at the last few pages, it explains it all.
