Followed around one of the other Superstock racers on his zx10 for a couple laps to compare. Previous rounds at Chang International he would leave me pretty bad down the long straights but looks like the tuning plus e85 has helped out a lot with straight line speed. We switched bikes the following session and both noticed a big difference in how much more pull my bike had in 4th-5th. He left me for dead down the straight when he was on my bike (rider is 20kg lighter).

if yours pull harder 4-5th, and he beats you on the straights, he is simply getting out of the curves faster...

I think

In the video u can see Iím pulling him in down the straight, but before last round at Chang International I couldnít stay anywhere near him on the straights. So, it looks like the e85/MWR filter and tuning has made a sizable improvement in my bike.

He was riding my bike and I was on his when he left me for dead..lol

First time i've read through an entire 15 page thread. Awesome to follow along and thanks for sharing. I'm looking forward to the day the rr is faster than the s1000

c) Forks through clamps 10mm and raise rear some more (max preload or shim it), just to test "push wide" issue.
d) If nothing helps then 23 degree rake stem inserts to shorten that huge trail the Gen5 has.

A) tried a bunch of different gearing/wheelbase (595-610mm) and it changes how the bike turns in but not really any help mid corner.

B) just installed rear suspension potentiometer and rear travel looks good but I tried more preload last session and did feel better but the rain came down before I could really test it properly.

C) shock is 311mm, tried flush and 10mm through with forks. With 10mm through it does help mid corner but the bike shakes its head a lot when transitioning from left to right/right to left.

D) Superstock so can't change the offsets

So on my gen 4 I had this issue too. All I did was we looked at the data from my aim and it felt like the bike wanted to run on. So we adjusted the engine brake to be fully off but in a linear fashion. So as I came into the corner it was coming off and then mid corner fully off and that helped a ton with running wide mid corner.

I found this issue the most at Laustizring against the Aprilias of Kev Calio and Tambourine. They could run in with more corner speed and I was running wide and having to wait to get on the power.

This year I am between running the ZX10RR and the S1000RR.

ZX10RR Superstock racebuild!!

Just back from worldSBK weekend where I put slicks on the Superstock zx10rr and raced in the Superbike support class. The race was announced late so not many of the quicker riders showed up but I still wanted to fix a nagging issue Iíve had with the zx10 for the last 6 months and finally get into the 1m38s.

Was right into 1m39s in practice on old tires but still had the hesitation/shaking feel from the bike on corner exit even after changing more parts that I hoped would fix it.

Into qualifying and couldnít really drop my time much when on the 4th lap I lost all rear dampening in the rear shock and had to pull into the pits, let the shock cool down and tried a different setting but the bike felt horrible so I just came back into the pits. Then it was scrambling time trying to get a shock for the afternoon race.

Found an OEM shock but decided to stick with what I was running and see if I could get race distance out of it before it let go again. made it to lap 9 sitting 2s behind 2nd position when the same happened again on a 3rd gear wide open T10-11.. got the bike under control and managed to limp through the last lap to finish 3rd. Also a new PB on the zx10rr of 1m39.2, getting closer..lol

A good track buddie got his Ktech rear shock sent by bus to the track for 8am on Sunday just in time to install with my spring and a safe setting that I though would work. In the 10am race I managed to smash my outright PB lap at Chang on the s1000rr from a year ago (1m38.6) and post a new lap of 1m38.2 on my way to 2nd position.

So, it looks like most of the issues I was having with the bike the past 6 months were all related to the rear shock. I did have it recharged and Oil replaced but looks like thereís more wrong with it so itís on it way back to the UK to get checked out. Will pick up a new Ohlins KA-468 to test out also as itís always good to have a spare.

Once I changed to Ktech cartridges and some clutch modifications it actually went the opposite where it was turning in too early. Played with geometry a little more and itís sweet now.
