Decided to check the left side for good measure. Glad I did. Looks like I put the welder away too soon.
I broke the cam on my '03. Got it used about 3 years back. Only 2000 miles on it. Rode it 100 miles and the cam broke. The outside edge of the hole you screw the sprocket in broke off into 3 pieces. Those fell down into the stator and took that out (cost twice what the cam did).
Any idea what might have contributed to the peg frame mount cracks? Haven't seen that issue on a 630 and not sure it was a common issue on the 610.
I'm around 230. I shouldn't be that heavy, but the reality is that I'm sure lots of folks ride these bikes that are over the ideal 160-180# ideal weight that someone dreamed up. Bike has never been crashed at speeds above 5-10 mph, and those could hardly be called crashes in my opinion. Lots and lots of prolonged off road riding on the pegs. Might be something to check next time you have a wrench on the bike.
I'd be very happy you found the peg stress cracks now and avoided having a peg break off at 50 mph going through the woops.. seems like a good idea for the rest of to check for the same issue.
I was heading home from LA Barstow to Vegas solo heading through Death Valley when the right side broke loose. I didn't know what was happening until several miles later in a sand wash when things finally let go. No crash, but I was surprised to say the least. Almost lost the right side, but eased up and rode the seat home.
Apparently the Hammerhead shift tips stick out so far, they're the second thing to hit, after the pegs, when you're getting low. Mine hit and grabbed and I thought I was about go down, then realized the shift tip was floppy. So I made my own, stock length, but further forward and higher, that uses the Hammerhead pin and rubber, but is a lot sturdier where it matters, and can actually fold up out of the way, instead of being awkwardly long. The shiny spot in the middle of the hammerhead was where I filed and sanded the sharp edge off that was poking into my soft street boots...
last month i tore the sm down to hunt down a wicked knock! i sounded like a connecting rod or something very bad. found this very broken key on the crankshaft(clutchside). it had started to shear then cracked in half! i went through the bike and inspected a bunch of other stuff while i was in there. it got a fresh set of gaskets too.
it's the 2009 model. 3000-3200... I'we changed the woodruff key,the nut,and put some special cream so it wont open again. Hope it will be ok. It needs to be checked now ant than.
Hey lunger, the 09 sm610 had 12000mi when the noise and vibration from the crumbling key became noticeable. it is too common, ive found... i feel like i should be looking at the older one before it lets go.
