Performance suggestions for my S4

[junior varsity]

They can be obtained through Motowheels at a pretty good price under member discounts, last time I checked, just over 3k up to 3.5k I thought.

really going to make that much difference than my magnesiums?

approx a pound a half of rotating weight per wheel removed.

you could go with really lightweight rotors (like the ceramic ones) and make up most of the difference I believe.

If you have mag wheels already I wouldn't change to BST's, there's not enough difference. I would do the suspension then the brakes (calipers/masters).

If you are going to do a CF tank look at the ETI fuel cells, the DP are prone to leak.

You are better off waiting until you can do the whole motor at once like ato said. It would be a pain in the ass to do just a little here and there. Also, for 2grand your not going to get too far, new SPS cams run $1,200-2,000.00, pistons $500....

Just ask me how I know, Commonwealth is finishing up the motor on my 1036CS:

Ducati 1036CS First Start after Engine Build.

Great advice guys. After sitting down and thinking this out. First plan of attack is to lose bike weight, suspension, cosmetics. Then build the 916 out all at once. Also, send me some links for some engine performance parts.

You might think of acquiring a nice "box" to put supplies in. I do this with projects. You slowly accumulate the necessary parts and eventually you'll have everything you need, then you fill a piggy bank for labor.

Where can I find the SPS cams?

[junior varsity]

Call Mark at Ducshop and talk with him a little bit. He should be able to provide insight into DP or SPS cams, there's also possibly VeeTwo cams available online through their eBay shop.

You can pull your heads and have them sent to DucShop or MBP to have them ported a bit.

Nichols lightweight flywheel.

Don't know if your exhaust is a full system, but that can open things up.

Lighten up the clutch.

Look at gearing.

Brake Rotors.

Lightening: Get rid of the world's heaviest battery. You could use a smaller conventional battery, or a 123A pack (Speedcell). Carbon fenders and tank. Replacing small parts with carbon is more decorative, but bigger parts give a measurable drop in weight. The brackets for several things on the bike are steel and don't need to be - Examples include the fuse box bracket on my bike. No reason for that thing to weigh so much. Headlight bucket is heavy and a carbon version is available. Replacing cast parts with billet - sidestand is very heavy, triple trees and rearsets..

The VeeTwo SPS 4v cams a no longer available, checked awhile back.

An option on cams would be SPS intakes and G grind exhaust. I would however do what the person helping/building recommends to get the most out of the motor.

very helpful. thanks guys.

+1 on the BSTs they were by far the best upgrade I put on my S4. I'll be doing the rotors too before I  get around to upgrading the engine innards too. The guys at motowheels are great it's more than worth the $ they have for them. Just make sure you have your wheels put on by someone competent. I went through hell with mine.

I drive to Nashville from time to time. If you want to test my bike out to get an idea of what a difference the wheels make.

I also have a set of ST4S headers along with the stock cans if your wanting to keep the low mount exhaust look.

Yeah they would be great, message me when your headed though. Thanks for the offer.

My 01 S4 w/ 30k miles; tweaked for lightness (now if I could lose some weight... ).

Mag wheels, carbon tank (DP, but no leaks after a full bit of reparation) pod air intake, shortened arrows, braketech rotors (front), numerous TI bolts and a few other tasty bits that I find aesthetically pleasing.

Ok, so I am mulling the BST wheels. You guy's really believe in the performance vs cost ratio over piston/cams? What would my red Marchesini's be worth? Thoughts on Ohlins forks? I want performance, and would help cosmetics as well. Or would I be better of saving money with Race Tech and have the forks powder coated?
