Chassis setup. Please chim in
my bike is setup with a heavy duty coil. I got it because im 240 naked but i think its keeping the bike from hooking well. Im at 68in and the shock has been revalved. The bike goes down about a inch when i sit on it and then its super stiff. Wonder should i go back with the stock coil. Right now i cant leave higher than 4500 without it spinning. Rear tire is set at 16psi a hook up. I need to know how far do i tighten the coil

Check your clutches first. It sounds like your suspesnion should be fine. I bet when you try and pull out your steels that you can't get them out. It has happened to me several times and I blame it poor track prep and bad tires when the real problem was my steels.

Really we need a video of the bike leaving the line to tell what is happening ... But from the sound of it the bike is dropping in the rear on leave , then a few feet out the bike is popping back up unloading the tire... If that is the case you need more rebound controll or the spring is just to strong for your shock settings ... This is all guessing on my part without seeing it first hand ..

Just pull them and see. If any of those steels are dificult to get out that means its warped. It will cause your tire to spin. Unless maybe at your weight you need more than a revalved shock. I am just throwing ideas at you.

One way to test the spring and shock if it is really the problem is to losen you front strap , If that helps then you are not getting the weight transfer you need ..

I agree springs and spacers are too much ... Just use the spacers and stock springs ..

Who did the shock? I've used brocks springs with true street spacers all last year I'm going to try out the Adams real street setup this year

wheelie it comes up slowly. But thats when im pushing down on it with no weight on the bike. The shock is revalved. It just act as tho its not being put to use.

the guy on ebay that does it for 150 or so. He asked for height, length, weight, hp and what its being used for. He also added a schrader valve to it. I havent touched his settings on it. I was thinking maybe the coil had something to do with it.

It compress but i dont think enough. I feel it squating but it doesnt do it very much. U know how urs touches the rear tiger tail. I have maybe 2in between the tail and my rear wheel. It wont touch it unless i have someone else riding with me.

did you set it like the directions said? Check your undertail is it rubbing? He did mine also. Where is your tie wrap at the end of a pass? I've only made 4 passess on mine. I have 08 busa spring on it and had to tighten the compression and rebound springs to stop it from hitting my tiger tail. Bike is about 68-70 I'm 240 in leathers

im about the same. i hadnt used the tie wrap. At first i had the coil to lose and it was hitting my tail. I tighten the coil and it never comes close to touching. Mine coil is probably close to the one wrongway has.

The shock rebound is slowing it down where it is noticeable when the spring is compressed is a good sign the valving for the rebound is working. If the compression screw is too tight it wont allow the shock to compress enough when the throttle is hit and would act like bottoming out a shock causing tire spin. Where is the tire spin at the launch?

it grips for the inital hit and then spins before the 60ft. Its almost as if i cant throttle it hard. As soon as i feel it bite and twist it just lets go. Like smokin was saying the pogo effect. With the pull down strap tight it will not grip at all

It could be that there is not enough rebound that far down the track. A rebound too soft will usually unload the back tire within the first 20 ft. You might have to loosen the rebound a bit. If the suspension is not traveling it will spin the tire or wheelie.
