Here are my thoughts......if you put a heavy spring on a factory zx 14 shock you will have suspension problems. The factory shock is valved to match the factory spring rate. Your bike is probably rebounding WAY to quick with that heavy spring. That spring is over rebounding the shock which would cause you to lose traction. Picture this, your bike squats at take off very quickly. Just as fast as it squats it comes back up at the same speed which causes your tire to lose traction. I'm no pro but or expert on suspension but just my thoughts on your suspension. I think I remember WEE trying the Busa spring and said it was too stiff. You really should not spin at 63 inches even on a poorly prepped track. My local track blows and I rarely spin and I am at 65 inches.

Shinko spinning problems.
Here we go again with the u-soft not being able to hook as well as more costly tires. First off if track conditions are poor in a high power application (275 hp or better) you are not going to hook with a flat slick. But in the real world of normal street bikes with maybe a small shot of nitrous (75-100 hp), the u-soft shinko will hold that all day long even on long wheelbase bikes if the chassis/clutch/suspension is set up correctly. And oh, yea the riders clutch hand and throttle control. I have gone as quick as 1.29 short times on a 66 inch bike, and as quick as 1.35 on a 63 inch bike; all of them using the shinko u-soft tires. The stock shock on the zx14 needs re-valve/spring if the wheelbase is extended and power is added. Just as the gentleman stated in the earlier post, going with only a heavier spring on a bone stock shock is only going to cause the tire to unload/spin after the rear shock begins to abruptly rebound after the launch. The new drag race shinko radial is awesome, and has fairly long life for a tire that soft. I personally tested that tire 4-5 months before it was available to the public with geat results on turbo zx14's in excess of 400 hp. It is a lighter tire than the stealth series which will greatly reduce centrifigal mass and can be ran a higher pressures to reduce rolling resistance. The quality/value of the shinko tire is tough to beat. That is not to say that the others are not good. I am directly sponsored by shinko/wps but I still use the power one, and the mickey mc2 on customers bikes. All of these tires work great, but stll require a good chassis/clutch/suspension/rider set up to do so correctly. That just my 2 cents for what it is worth.

I didn't dislike my 003 but I do like the power race a lot better. I can run 8 more psi. Also with the 003 one out of 8 passes it would break lose. The Michelin dosent lose traction unless I get out of the groove. I would like to try one of these new tires.

ill be running one! however, i had no spin issues with my r003 after i started getting the chassis set up a little better. kept adding psi too.... chassis was way off initially....i damn near looped the bike at about 67 in wb when the clutch/2 step was set a little high. the tire hooked. going a little longer, so i may need the drag radial or mc2 for the night time races

All these MPH vs air in the tire things always get me......
We have a guy here, who tunes the bike with TONS of air in the tire......, like 20 lbs in a MCR, and has damn near hurt his rider more than once........chasing the almighty mph though the traps........
and my stuff has run 124 in the 1/8, on stock motor, with 8 lbs in a shinko u soft.........
Its not like you are going to gain 3 or 4 mph from tire pressure......., unless you go from 2 psi to 20........
I really want to see this tire , and I will have some first hand experience....., my buddy got one, and I tune the clutch on the bike, and know what it has done with the shinko u soft, and dragtec.......,

I see guys spin at that wb all the time......, maybe not on the starting line, but down track..........
But, only a few guys on here have run at my home track........

Good/simple stuff that hopefully people will understand.
I've done 1.37s on a regular 003 Shinko and never really found I needed an ultra-soft. This was with my ZRX sitting at 63 1/2". 100ish ft pounds of torque. Wilbers shocks set up for my bike and my weight.
I'll continue to spend my money wisely, and to me, spending close to $100 more for a tire when the Shinko works...kinda loopy IMO. $100 goes a long way in weekend racing fun for me.

Nox, I gotta disagree with you here. It depends on hp and total package weight. My bike picks up 2mph between 15 and 25psi. Another rider picked up 3.

From running the 003 at 10 psi to the Michelin at 20-21 psi I have run 2-3 mph faster. I have made a few other changes but I don't think any of them would help in mph. It could be a coincidence...

I've always heard you can pick up mph with more psi....never really paid much attention to it myself though. Might have to experiment on a few passes to check it out.

or the fact that you're running in colder denser air than you were in the summer when you still had the shinko. At stock wheelbase I ran the same MPH whether I was on the Shinko soft at 18psi, the Tomahawk T-3 at 16psi, or the Pirelli dragon at 30psi.

We've done the best 60 foot we've ever done on shinko u soft 1.29 where 69 inches long we also have a 7 inch flat slick and it hasn't done any better. But not all tracks are created equal. We was recently at a track that was not so good. A friend of mine had a turbo bike that would spin with the turn of the throttle using a u soft. Another guy there loaned him a new power one the bike started making it down the track. Same Day same bike both tires new. That's evidence I can see. I want to run the new shinok but couldn't get one in time so I purchased a power one. I haven't tested it yet but hope to this weekend if the weather holds up. I hope someone here with good power could test the new shinko. Ken

there is a fine line on the mph gain, vs, losing et, because of spin........
If you have a track consistent enough to tell......, that is great......, I found tiny gains in mph, but, then found the wheel spin issue.....
Every bike is different...., but, you gotta do what works for you where you race........
NO ONE can run those crazy tire pressures at my home track......, it would put you on your butt, or in a cloud of smoke

Took mine to the track today. Very very very nice tire just wait until you feel how soft it is after it has been heated. Ran the highest psi I've ever used today(20psi) with NO spinning they even drug the track 3 times and still no problem. Had to end my day early due to spinning the wheel in the tire.

were you at pinevalley or evandale .. was the tire a loose fitment at time of install on rim .. like you could just push it on the rim .. i'm planning on getting 1 but i order a usoft 2 months ago when it was a steal ..

i've got dads sitting in my living room floor waiting to ship to him since it accidentally got sent to my house. It looks like it's gonig to be bitchin. I can grab the sidewall and just about touch the inside of the tread with it by squeezing it with one hand. The rubber compound is also VERY VERYsoft (which was to be expected). I wish that I was going to be able to try it out but I'm sure dad will give a good report once he puts it on the zx12 wheel that I sent him. If it'll help anyone it'll be him since he races on a TERRIBLE track and he's only 145ish lbs.
