Too much gearing, when you add power you dont need as much gearing.
Hell with my big motor i was running 18/40 for gearing and still had problems. lol

Man, i just couldnt let it go like I wanted to all night, and the front end coming up was making me modulate the throttle on every pass. I could almost be sure that if i could have let the clutch go sooner and stay WOT that the mph would have been higher too. I guess the extra 10 hp or so really exposed my suspension set up last night.
Then you need to put a 46 tooth on the back...The colder it gets the more your gonna wheelie, so your gonna need a 45 or a 44...

The suspension set up did need the change for sure. Last time out before the head I was pushing the bike for 1.3's and felt some wheel lift right off the clutch, but with 1.42-1.45's no lift at all before. Now it tries to lift when power builds and most definately will if I throw the clutch away. The ass end is squatting to the bottom right when the bike lurches forward. Smokin was right and Nick confirms also that even before the head, my stretch was making my shock move too much and the added power made it much worse. I guess what I am saying is if I was happy with mid to low 1.4's before, then the old shock set up was fine-but I wasn't happy, long bikes should go 1.3's and no way can I keep the throttle wide open with the way it was last time out. I am pretty sure it will pull even more mph if I can have the throttle pinned between 1-2 shift. It isnt too much gearing either, I am only in 4th for a full second at the end of the 8th mile.

I agree with the shock, get video to watch and listen to your runs, maybe the adjustment you need will be you.

I had a really cool head last time out, the bike was getting hott fast as well so i had to let it cool down. Its not much more power like a small shot of nitrous, I just need to come off the clutch faster and keep the front end down between 1-2 nd gear. If you ask me, the bike needed a little more power, and it has it now. Once I run this weekend, if the re adjusted shock holds the bike down- then I can get in sinc with it.

I don't think the oem shock will work properly. Maybe it will for you.

I think it will for 200hp, maybe not. What shock and spring did you have?

You do have a revalved shock, correct? If you do, try to push the rear of the bike down and see how long it takes to rebound back up.....
-I have a busa shock on my zx10 with the 10 spring... when I push it down, you can bearly see the rear come back up.... I have the top on soft and the bottom on hard (then go back the opposite direction about 5 clicks); my bike is only 62 inches.
that suspension is so important, most folks don't understand how much so it is.... I learned from the car dudes, they will test the suspension and not worry about the motor until they get the chassis right.....

That stock shock is not up to par for your power.

I guess I need a shock for 185-190 lb suited raceweight, I thought I saw one in the classifieds a while back.
In the mean time, I'm going to try the stock one with the recomended adjustment since I had it opposite last time out.

JZX, I recommend you turn the shock collar on your rear spring 3 clockwise turns to have the spring do most of the work not the compression adjuster...OEM shocks are set for 150lb. riders, so if your heavier then you need to adjust the spring compression not just the compression with a screwdriver...
If you want to go faster then you have to get IN the gas faster!!!...If you cant then you have to adjust the gearing not your throttle hand...Unless you bracket race and want to run a certain number...
Hope this helps???

+6 in the rear is ok for my weight in my opinion with the marginally better power it makes now. If I was 150 suited I would have pretty close to stock gearing.
I haven't even seen a spring collar tool in years, but I think I have a nieghbor close by who has one. I will take it to the track with me and try one thing at a time-it's pretty obvious where the problem occurs at so whatever works shouldnt take me 10 passes to confirm. I hope... thanks for the help!
