I install the PC ignition e bike this weekend, and added the timing that my engine builder told me to add thinkin i need to add more weight to the lockup, i think it was slipping on top end somewhat. hard to tell if it helped out. I knwo we ran alot more consistent, i don't think the timing i had added made enough power to make th clutches slip. Has any one sle instaled one and tryed it out to see if they like it.
