Just wondered what you guys do to your bikes when you take em to the strip. I'm more concerned here with the people that don't have"drag specific" bikes but guys that ride them all the time and change some stuff at the track. Kinda figured since we havea drag racing forum we could pass along some useful info. I personally just strap down the front end, i'm not knowledgeable enough to screw with my suspenesion. But if anyone does anything pass it along and I'll give it a try this weekend. Some of the guys i ride with soften their rear suspensions to try and give the power somewhere to go other than pulling a wheelie and losing time.
See I had heard that stiffening up the rear makes it easier to wheelie. Stiff suspension means when you romp on it you won't lose as much power in body movement. hence that power becomes either wheelspin or a wheelie?? Made sense to me at the time anyway.
Hmmm. I can't remember. Have to get back to you on that one. I know my preload (rear) is cranked down to two from max stiff and I added in a little rebound damping up front to try and stop the headshake, neither of which worked so it was pointless. I've been contemplating going back to the stock settings anyway so lets just assume we're starting with a bike with stock suspension settings. Besides I wasn't really looking for a setup for "my" bike specifically. Just some guidlines for everyone to maybe knock off a couple 1/10th's.
The key to the rear suspension is how the swingarm is in relation to the pivot point under load. Meaning.............When you sit on the machine, is the machines' pivot point above or below the rear axle?
Ultimately, the pivot and the rear axle should be in line with each other while under power! See Attachment!
