Slip is a much better teacher than I!

 

I love the 520 chain kit. no problems on mine yet... best mod i did. wheelie machine. still goes approximately 162 mphs top end. i don't need to go faster then that...i rather have more low end then high end. 520 is the way to go...

 

After a very exhuastive research I did go with D.I.D.'s new 520ZVM2 chain. (currently the best on the market unless you shell out the real cash for Titanium) Cycle Pros in Mesa, AZ is installing tomorrow and I'm hitting the tortilla flats Sat. morning. Can't wait to get that wheel up in third gear with just a roll-on at about 120mph.

Oh yeah, don't forget to clean it and keep it lubed!

 

By going 520 you are dropping about a pound or more of rotating crap, it definately helps, i haven't done it to the cbr yet but when i did it to my 10 year old thunderace, it felt like i was getting a new bike!
