Couple Morini HPI mini-rotor questions

Got this with our last treats order for my friend's M1 build and went to check the stator fitment and the plate will not seat within the tabs that hold the stock stator plate in place. We were able to get the plate to balance on top of the tabs (just barely) and still be able to bolt it down but that didn't seem right.

Ended up grinding the inner faces of the retaining posts and were able to get it to fit inside nicely. Forgot to get a pic of it seated fully...Anyone else had this poblem?

Also, when the flywheel is installed on the crankshaft, it is impossible to adjust the stator plate left and right because the OD of the mini-rotor covers up the stator mounting screws. We can really only adjust the stator and and tighten it down when the flywheel is off. Is this right? I can adjust the hpi stator plate (red version) on my puch while the flywheel is installed.

chris, i had to get a friend to lathe the od a long time ago on one these. just grab the capliers and email the treats gang to see .. if yours is defect, it happens. if you have a lathe or know a machinist, very easy fix.

oops. didn't see the typing under the pic. (edited)

Thanks for the info Ed! Stator now fits nicely within the mounting posts so that is taken care of. I guess now just wondering if it's normal to not be able to tighten down the stator while the flywheel is installed?

huh never hpi'd a morini. well, truthfully ive never managed to convince myself to pony up the cash and put an hpi on anything. i think if i had one i'd sell it and have spare moneys...

regardless, they do kick ass

Also, the stator we have is different than the one in the picture treats has on their website --->

as well as the picture that was in the included instructions printout (same as one above.) --->

Our stator does not have the two lone fire marks and one spot with degree markings, but instead two separate degree marking areas with one little downward arrow in each that I assume are the two different firing marks, left one for CCW spinning and right one for CW spinning rotors. Here it is mounted up now after dremeling. --->

Mine fit like a glove. Have you gotten it running yet?

yup this is same as minarelli v1

the arrows are where the marks should line up at 2-4mm btdc

it is normal not to be able to adjust the stator when the rotor is on

Had it sparking by turning it with a drill but haven't had a chance to fine tune the timing yet, will have more time again tomorrow. Thanks for the info guys!

Any additional thoughts on this? Thinking about picking one up for the m101.

mine had the same issue I kinda forced it in place and once it made it in it turned smoothly. The clearance is a little tighter than it probably should be, but I got it to work on mine. I also had a puch one.

I would think that would be impossible to get the timing where you want if you cant adjust the timing with the rotor on. I mean your not running on the key I assume so unless your crazy good at lining up marks you made I would think that would suck!

It took some trial and error but we were able to use a locked micrometer that was dialed in at the right timing (2mm btdc) sort of as piston stop to get it right. Confirmed with timing light afterwards.

Yep. That's how you do. Presumably they want you to adjust the plate but I never have. They also recommend "experimental" timing ranges but around 2 works well.

One thing that makes it less of a pain is using m4 socket caps instead of stator screws. Either way.
