velocity stacks and ceramic wheel bearings

hey fellas need some advice. thinking about putting some velocity stacks from orient expresson my 06 zx14 . i have the 1417 kit ,,heads and cams. what do you think, should i?will i get anymore gain. 212rwhp now.
2nd question are ceramic wheel bearings worth the money. do you really see any improvements with them

You can expect a bit more top end with shorter velocity stacks. OK on a bike that spends all its time at high rpm but you'll lose it at the bottom. What modifications have you done so far to get 212rwhp ?

Ceramic bearings might be the last thing you would do after you have done absolutely everything else, unless you have a mega-bucks sponsor. More cost effective gains will come from correct gearing, lowering the bike and careful attention to aerodynamics.

The bearings greatly reduce rolling resistance.

Are you racing - if so what type of racing

Bob - How did you lower your bike - front and rear...

Yes they do when you spin a wheel with no brake caliper or drive chain attached, that's where the rolling resistance is compromised and why I said "when you've done absolutely everything else"

KSP, I use Muzzy links on the rear and a combination on the front of a 1 centmeter drop of the triple clamps and a strap.

On track and dyno testing have shown hp gains & spool up time gains from ceramc bearings. Been used and proven in Supersport racing for years not just on a stand in the shop.

They use race chain though not 0-ring and have you seen how long those ceramic bearings actually last ? The top teams are changing them every meeting. I'm not trying to rubbish ceramic bearings, just pointing out that you really need to know what you're getting into.

The ceramic balls have a much longer life span than the steel and I have used the same set in several bikes over the years with never sticking or grit issues like in steel ball style.

What top teams change them every race that you see? Maybe they change them because they have a budget to replace everything like pistons, rings, bearings, etc.

None in drag racing do and these bearings are also used in industrial applications where they have greatly reduced bearing failure down time in factories.

ceramic bearings are the way to go. i have them in my transmission, water pump and wheels. i have made mucho top speed runs at maxton and texas with them and they are in as new condition. way better than steel in every aspect.

If you are seeing ones being changed out all the time they are likely not the good ones made by WWB. Good info here:

"1st, this is not a sales hype in anyway... I normally don't go on forums but I want to educate everyone about safety issues and bearings. I have no problem if you don't buy from us but here are some things you should look out for when purchasing;

- Make sure the balls are not white in color, these are ZrO2 Zirconium not Silicon Nitride and will not hold up in any Motorsport's application.
- Make sure the ball is a USA made ball, we only use Cerbec Balls but MRC/SKF as well as Hoover also makes balls here. Chinese balls will flake apart or shatter.
- Also look for a nylon cage, some of the cheaper imported Ceramic Hybrids use a steel cage, this is a common low grade mass produced item.

We had 1 customer complain that ours were $75.00 a bearing and he could buy them for $55.00 a bearing. The bearings he purchased were in a Microsprint wheel and lasted only 10 practice laps! The same customer has 1 full season on our wheel bearings with zero issues. I never started the ceramic bearing thing to be the cheapest just the best and safest.

Everything we assemble leaves here 100% right. By doing everything 1 at a time by hand we can adjust the clearance per application, every ball we purchase is made to our specs. I could easily buy cheaper ones already done from overseas but they wouldn't hold up (believe me, we have tested them all).

If anyone has any questions on bearings I am here 5 days a week. We will also be at the PRI show in 2 different booths, one for Cerbec, our ball mfg and the other for TKO our automotive reseller.

Stop by and say hello,
Dave
WWB"

Our bike has hybrid ceramic bearing from WWB, the cost was nominal, more expensive than steel ball bearings but you can't hurt them. They have been in one of our bikes for six years and still function like new.

We first bought them for an old dragbike's front wheel. Just out of curiousity we propped up the front wheel and gave it good spin with the old bearings, it spun for a little over a minute, felt fine and we didn't think we were going to get much of a gain over the old bearings. We couldn't have been more wrong, we gave the wheel a good spin with the hybrid ceramics and it spun for a little over an hour !!!!

You want another example? Ok, last september at Atco NJ I was pushing our dragbike with a Zuma, just cruising along the return road, the girl in the timing shack motioned for me to come over so I just gave the bike a little push and told the rider I would catch right up. Well, the girl wanted to ask me a question but was talking to another racer so I had to wait for a minute, she asked the question and I took off, keep in mind that the timing shack is way past the finish line, the bike was at the starting line. It had rolled more than a quarter mile at about ten miles per hour and the rider hit the brakes to wait for me before going around the corner by the old tower.

We have WWB ceramics everywhere you can put them on a bike, its money well spent.
