LMH clutch

Hey guys,
I have a question for those Lite Machines experts. I noticed that there are two different part numbers for the V Max 6 and V Max 7 clutch shoes. I know the center bore is larger on the V Max 7, but is that the only difference? I notice between the two that the 7 has more machining done where the shoes flex but is that a design upgrade or is that specific to the 7’s clutch? In other words, can I use the V Max 6 clutch on the V Max 7 if I bore it out to fit the 7’s clutch shaft?
Thanks guys
Steve Z

I can't follow you..

Differences between the two, one is standard and the other is heavy duty.
The HD engage at higher rpm.

I wouldn't mess with this clutch shoe outer diameter.

IMO, don't modify dimensions.

Let me explain: I have a new clutch on a V Max 6 engine. I just purchased a new LMH 117 kit with a V Max 7 engine. Now the V Max 6 clutch has a center bore for the 3 mm clutch shaft while the V Maxx 7 clutch has a center bore for the 4 mm clutch shaft for the .074. However on the V Max 6 clutch, there are two machines “ circles “ on the clutch which allow the shoes to flex outward. The clutch that came with the V Max 7 engine has more material machines away where the clutch shoes flex, machined “ ovals “ instead of circles. I wanted to know if that additional machining is specific for the V Max 7 engine only. I only have one clutch plate for the V Max 7 engine but I have several for the V Max 6 . If I drill out the center of the V Max 6 clutch plate to fit the 4mm shaft, will it work as a spare for the V Max 7 engine?

According to your explanations, as far as don't interfere with your startup procedure, I see no problem.

Some Pic would be nice...
