1. Nice build.. Kudos to Jeff ! Hope my bike project turns out so sweet!

2. So how fast does it go?? Also, so the motor comes from a ninja.. is the bike actually lighter cuz the motor is in a 77 550 cb frame?

3. How did you brush it out? What grit?

4. NO KIDDING!!! Oh MAN,that is a sweet-azz machine right THERE!!! I bet that sucker just SCOOTS on a track!!! Extremely “light” and nimble like any track-bike SHOULD be!!! And with that ninja-500 engine bored-out to 600cc,I bet the torque this thing has,is almost TWO-fold now!!!

5. Race tires are pretty useless on the streets, coz they need (and also can handle) higher temperatures. As long as the are not very hot you’re better off with normal street tires.  

6. Fire it up!! Let’s hear it!! No joy!!
