I know that this has been posted here before, but has anyone else tried the high velocity intake porting and engine break in tips as stated at http://mototuneusa.com ?
I was thinking about trying the smaller intake ports. Just wondering if anyone else has had success with it. Let me know what you think.
I know that people think that smaller ports making more hp is absurd. And to break in your piston and rings you run it flat out?
The guy makes good arguments and I can attest to the break in tips. When I broke in my new piston and rings I did what he said and it's been going strong for over a year now.
