My center chaincase cover attach stud is stripped. According to the parts book, the stud and hex bolt spacer is shown as one part (06-0376). Is this stud really one piece? In other words, will I have to remove the entire inner primary case to change out this part, or does the stud thread into the barrel spacer? Any tips on changing this out?
Thanks

The stud is one piece with a hex barrel in between a long and a short threaded studs. You will need to remove the entire primary to remove and replace this part. Don't try to dismantle the clutch without the clutch spring tool. If there any threads remaining, try to chase them with a die.

Thanks for the bad news. I knew about the clutch spring, but are there any other surprises waiting for me in removing the inner?

The only bright spot is that I recently obtained a very used primary cover which I've started sanding and polishing on to replace the current one with all the vent holes drilled in it (I've got a belt drive). Now I can sand and polish the inner case so it will look as good. I've also got a left-side adjuster I need to install. Probably a good time to do that as well.

I see that Fair Spares has this stud in stainless for $29 US. Not sure that stainless is a big deal, as it's kind of buried and not easily seen. Would be nice though.

Thanks again for the help.

Not to take any sale from Phil, but as you said it doesn't show at all.

No other surprises in there. Make sure to make note of all the spacers positions on the crankshaft and watch as they tend to stick to the back of the rotor or crankshaft sprocket. Plan on replacing the snap ring on the gearbox shaft - behind the clutch basket. There are black tabs behind the three bolts holding the inner primary to the crankcase. Bend these out so you can loosen the and remove the bolts. Make sure to drain the oil before starting this work.
