Project 680RR

In theory having mounted the falicon rod with the xr only bearing kit, you should have solved problems concerning crank reliability...even running the engine higher than 9000 rpm...Crank failure are usually due to the oem bearing rod...it was bad designed: the steel rollers inside are too big, then accumulating a lot of heat, lead to break the bearing cage (too tiny) ...
i'm interesting about how the engine responds with a lighter 102,4 piston!!!  i would compare with my stock 102,4.....just to feel the differences  ...

The gas response is very fast and crisp,just like with the HRC piston.But I have a lighter flywheel and special CDI also.

What type of CDi you have mounted?

I had the lighter flywheel and that CDI before - with the HRC piston - also on my bike.  

If I find the time I will make a much larger airbox (maybe in carbon) and a newer, different looking backside on my 680.
