I recently swapped out my le partie for an hpi and could be having some issues with it. Installing it was pretty straightforward. I just had to take off a few mm of the adapter plate. The flywheel was initially rubbing the stator when tightened down so I broke out the sander, then lapped on granite, checked fitment then repeated till it spun freely.
I followed the instructions and set the piston to 2mm btdc and aligned the timing marks. It fired up right away and idles fine but is super sluggish till the pipe starts to hit.
Seems like it takes forever to build rpms and the engine stays super cool. The pipe isn't even getting that hot. Once it gets on the pipe it'll keep pulling.
I'm only ripping around the neighborhood at the moment so can't really open it up because of all the stop signs.
The bike was dialed in pretty good with the le partie. Jetting and transmission were close and this bike was like a rocket when the pipe would hit.
I'm running a bidalot rr kit and doppler pipe, 19mm phbg bd 94main, w6 2nd from top, 48 idle. Made massive power with the le partie. Really fast off the line.The only thing different is the hpi.
After reading about some peoples issues with the hpi timing marks not being marked correctly I put a timing light on it see if there's something going on with the hpi. I used a marker to mark the flywheel mark and the light is working fine
This pic is just an approximation of what I saw. The mark on the flywheel was definitely to the left of the stator mark. Maybe not as much as the picture shows though. I just moved the flywheel to the area where the light had it for the pic.
Is this normal? I had the light set to zero advance so the marks should be aligned, correct?
Trying to figure out what to do next. Should I go off of the marks the light is showing and re mark the stator where the flywheel mark is showing up then re-time it and go from there?
I previously used the light on the le partie and the two marks were pretty dead on.
Thanks for any assistance
