Hello My name is Mark:
I am new to the forum and new to racing bikes. I had a 07 GSXR with a stock Motor and extensions. I took it to the track a few times and got the bug to go faster.

I purchased a 08 Gsxr that was all done up just for drag racing. I have a few basic questions.

1.It has a Shinko Hook Up Drag Radial what PSI should I start with at the track?
2.The chain seemed really tight when I bought it, I loosen it up so it would have one inch chain slack. I noticed that the bottom of the swing arm looked like the chain was hitting it. Do I need to keep the chain tighter because of the swing arm and gearing? What would be a good rule of thumb?
3. I want to install a two step what should I use?

Thanks,

Your weight etc have to do with tire pressure.
How bad is the swingarm? Pics would help
2 Step how is the bike setup up Dynojet electronics or ecu?
Where are you located?

10psi and go from there. As for the chain it may of been loose at one time and did it.

the chain is still slapping on the swing arm. It looks like DME makes some type of Guard now for them I am going to reach out to them
