other than the 520 conversion....what other relatively inexpensive (<$500)ways are there to add more hp to your bike? I know you can get a Full Ehaust vs. slip on...but that can run almost $1K.

Thanks...

It also depends on what type of performance you want. Low end, top end, full range, etc.
I'm looking to get my heads worked. ported, polished, milled, etc.
Also going to look into getting mapped injectors. I want low end power. I have no use to make the bike faster on the top. 155 is plenty fast.

I haven't seen anyone in person who has this done, so all I have to go by is the website.
And Southwest Superbikes will be doing my headwork here in Dallas. I'll let you know what the dyno looks like when I'm finished.

Change your sprockets to get more torque, I am about to go down one and up 3 in the back, should be able to keep the chain that way.
I have 1dn in front and 2up in back...uses the stock chain length (although I had to screw in the adjusters quite a bit from stock) making my wheelbase a tad shorter (a few mms)

Changing the sprockets does not produce more torque it just affects how quickly the engine revs into the powerband.

If you just go up in the back it will produce more torque at the slightly higher rpm. If you go up in the back and down in the front that changes things more. Well anyway it produces more torque I could sit here and explain the math to you but I don't feel like it. The engine produces more torpque in a certain rpm range and changing you sprockets helps you get there at the sacrifice of speed.
