I did 11.53 on a stock wheelbase '79 ltd 1000. Had a 1105 kit, 29's, dyna S & coils. That was my 2nd time at the track ever.

That's good going Mike, well done

Very interested in this, I have a z1a with z1000 barrels and pistons , v and h pipe, K and n filters and dyna ignition and coils . This winter thinking of going the 1075 wisco and 29 mm smoothbore route so same spec as you guys above . Heres the question what will a 1075 with 29mms etc make at the back wheel on the dyno?:evil:

Would I be better with 1075 Wisco pistons or for a few dollers more Ape sell a kit with 1075 pistons and cams? Jay I would really appreciate your input on this?

Stever,

Get the cams. You'll thank yourself later on. You'll potentially lose some bottom-end torque but the mid-range and more likely top-end torque will be worth it.

Later, Doug

you can say that again!
if you run under 10 seconds, dropping a tenth is huge!

Any one got a dyno figure ??

whadda ya think a 1170 will run with a set of 32-40 flat/round slides, a streetable cam, a ported head with big valves, a slick on an extended swingarm and weelie bars?






anyone?:huh:

10.7 maybe a little better with a light rider.

i wiegh about 150/160 so i could be considred light.

Ran my 79 1000ST (Shaft) at the track last month and posted a best 12.2@113.5mph (80 degrees at sea level) My 60 foot time on that run was 2.15 sec...not good. Should be closer to 1.8 sec. Teminal speed suggests the bike will run somewhere in the mid 11's with a good launch. Bike has 1075, 34rs flat slides. Web Cam .365 lift, V&H megaphone.

Time slip says
60' - 2.154
330 - 5.302
1/8 - 7.920 93.32mph
1/4 - 12.205 113.47mph

Was my first time at the 1/4 mile track with a bike. Will try again before the season is out.

i have two bikes one is a 79 kz 1000 with a 1075 kit web cams v&h pro pipe 29 smoothbores dyna s ignition and 4 over swing arm.im 6'2 250 lbs it runs 11.50s all day on pump gas. the other bike is a 1980 ltd 1000 with a 1105 kit v&h cams v&h pro pipe dyna coils and dyna s ignition 29 smoothbores and 6 over swing arm.it runs 10.30-40s both bikes on street tires.

So, anyone getting addicted to the 1/4 mile? :blink: I can't wait to take my 615 to the strip.

Wow if you consider it these bikes are only 1 to 3 quarter of a second behind the modern fantastic plastics.

1 second in the quarter equals out to a few lengths,and in the street forget about.<br><br>Post edited by: fastestz1, at: 2007/10/04 17:44
