I agree , the tire i have is very hard in the center ..When i first looked at it i was thinging this tire is not going to work , it's to damn hard .. The factory tire i took off was softer in the center .. Thread contact was very small because the tire was very tall like road racing tire ..

Lee, I truly believe it was the starting line conditions the contributed to the tire spin. I'm sure your suspension is correct. Street cars kill a track quick.
I would keep the Michelin just in case you happen to run a race series that requires a DOT approved street tire.
Pat i still have my Hookup and i can use that for any DOT class .. But for testing mods and changes to the bike i'll use the 008 .. I need good base line numbers to know if a mod works or doesn't work ..I don't want to post a mod that i'm not 100% sure that it works ..I can't do that if i spin one run and not the next run .. We have a limited time at the track to test mods back to back and i have to have a tire i can trust ..

Lee, I'm glad you posted these videos because it helps clear up some of the things we were talking about a few months back about what RPM should you leave at. I had stated that the 14 needs to leave around 7500 depending on the rider's weight and length of the bike. You had stated that you leave at about 5000, and that is a true statement, but I think where are two stories start to come together is not where you put the RPMs. Before you leave, but the actual RPMs that you use to make the clutch come in. in video 2 it is hard to see the the RPMs clearly, but it would appear you're bringing the engine RPMs up to about 4 or 5000, but when you leave the RPMs go to about 8500, and then the clutch starts pulling in. The reason I'm bringing this up is for the guy that's trying to learn how to ride there 14 and trying to make it leave at 4 or 5000. The engine really makes it's best torque at about 7500. I realize on a short wheelbase, this would not be possible, but for the guys that have arms. 65" or longer 7500 is a good place to start and maybe higher if you're heavy.

I had a feeling you would be going to the track last night. Weather is getting better, but still not great. I got rain last night just after 6pm.

I just thought of something that would really help a lot of people, if smokin, and wee posted a video's of their run, showing the RPMs where they leave at and where the clutch actually starts pulling in. Both have cameras, this would show both the ends of the weight, and what RPMs. They are actually using to make the bike move. Just a thought.

Last night because of the track i kept it just below 5k .. But yes i do feed it throttle as the engine starts to load as the clutch comes out .. Last night i was very slow at feeding it throttle, if i feed it too fast it would spin so i held the clutch a little longer...If the track is working or tire is working i bring it up much higher, 5500 to sometimes 6500 .. The trick for me is to use the throttle as the clutch comes out and not let the RPMs drop out of the power band .. I do this at stock wheel base also but stage at 3500 but the clutch release and throttle feed is much slower ..Same action but slower ..
Once i got the 008 tire on they bike and can leave hard i will get a video of it .. That should help some of the guys here see what takes place when i hit low 1.30s 60s ..

I have corrected people about this a number of times. The rpm sitting at the light is the "staging rpm" and the rpm the clutch is flashed to is the "launch rpm". My prior staging rpm on motor was 9000 and when the clutch snapped in it would be at a 7000 launch rpm during throttle turn.

My staging RPM is lower then my launch rpm. I stage at 5,000 and it flashes to around 7,500 when I start to launch.

Steering dampner ?? If not, get 1 and tighten her tight , tight. On launch Front wheel gets very light, easly turned. Swapping tire groove's , could cause spin , picking up dirt between groove's, got to cost 3,4,5. 100's in 60'
1.30 @60 = 50.51 mph = 74.098' per sec = 7.4098' per .01 sec
.......................................................................................................................... .311' differance
1.37 @ 60 = 48.39 mph = 70.988' per sec = 7.0988'per .01 sec
.311' x 12 = 3.732" x 7 hundredths = 26.12"
1.30 gets to 60' = 26" before 1.37

Yes One of the members is having a big problem with his ZX14R .. His does it so bad he said he can't ride it at all at the drag strip ..He said just driving down the road and removing his hands from the bars it turns right ..

Steering Damper ? Well that might help if that was a problem .. Jesse had one on his bike , i rode it a few times and didn't seem any different to me as far as going a little left or right .. I wasn't having a problem spinning down track as you can hear from the videos ..If you look at the videos you will see down track there was no grove .. 100 low powered street cars don't make a grove down track .. So i never corrected the bike going down track .. Had there been a grove and i had got out of it and spun i would have corrected it and steered back in to it .. But since i was hooking everywhere but the starting line i saw no need to drive around looking for it ..
My 2 other ZX14s and ZRX did this also as well as other bikes i have rode .. Most times right down the strip like an arrow . Sometimes a little right and sometime a little left .. I don't find it to be much of a problem for me so i'm not all the worried about it .. In any case i feel it was either me or the track causing me to go a little to the right and not the bike ..

Tire on the top is the power one 2ct .. tire on the bottom is the shinko hookup , both tires on rims and at 17 PSI .. You can see the power on 2ct doesn't have the contact the Hookup has .. The hookup has an easy inch more contact ..

I can't believe the power one didn't work for you.. It works great on my bike and also worked on Leonidas turbo 350hp zx14....
I can't see how pro street guys use the tire but a stock motor bike can't hook. Something's not right about this picture.
