Dad has a 2004 1M 900. Bought it this year. I was told to look closely at the clutch on those, since they have a weak spider gear.
Long story short, I put a comet 108exp on it. Since then I have broken two retainer bolts. I noticed that the AC clutch had a dampener that went inside of it. The comet didn't have anything like that. The first one didn't come with a lock washer, so I put one on the second Bolt that I put in it.
I know the 900 has a lot of vibration, but two broken bolts in one year?
Checked the crank with a dial indicator, and it was good. Torqued it to spec.
I would apreciate it if you can throw some thoughts / Ideas my way. I'm perplexed as to why I would be breaking bolts.
