Does anybody know what kind of power gains you get when you mod the zorst and carby for extra power on 98/99 zx6s.
Or has anybody got a link.
Cheers

Roughly...
A slip on and jet kit will get about 3 to 6 hp.
A full system and jet kit will get about 5 to 10hp.

Agreed on both counts.

All i need to do now is take 'er down to a dyno one day and see how much umph she's actually GOT.

Forgot to mention too that its not so much the top end but the amount that it fattens up the mid range that makes it well worth while.

true, of an hours worth of riding, i only ever spend maybe 40-60 seconds max anywhere near the redline. Usually am punting about from 4-8.5krpm

I was thinking 5-10 horses aint much but with a nice flat torque range wuld make a differance.
whats the $$ for this including installation.

If you are patient and keep your eyes open on places like ebay you can get a good deal. I Got my full Yoshi system with Ti can for $660 delivered and another $160 for a Factory pro jet kit. Not sure on install prices though as I did it myself.

Edit: for example http://cgi.ebay.com/ebaymotors/YOSHIMUR ... 4134QQrdZ1

costs vary from bike to bike. mine i had to take all plastics off, drain and remove radiator, remove oil cooler and frig about for frigging ever getting it to fit took quite a while even though i'd had a lot of practice at it (i had to unbolt everything off the fairings, lights, idiot lights, the lot).

Newer bikes i suspect theres less to take off as the fairings are the top and two side peices,

these bikes are very similar to 98/99 ZX9R's, which are lucky in that they dont really lose much (any!) low down power with a full system, unlike most other bikes

dyno graph for an akra full system on a 98:

dyno graph for a akra slipon:

doesnt tell you much tho, as they both start off with very different power figures... pretty normal for different dynos on different days with different bikes!
