Followed the advice here on the forum and replaced my bolt even though my second hand Burgman only has 4000 miles on it. I was very surprised at the amount of wear that the bolt has on it.
Bolt on 2012 is 2 or 2.2 ml longer than previous and bolt seat in pulley rework as well by Suzuki, please advise how it look when you check it. 2-3 photo would be good.I changed out mine twice in 34,000 miles in my '04 and it looked much like yours. I haven't checked my '12 yet in 17000 miles but should next time I change oil. I had understood that the '12's didn't need changing as often. Should check it to find out I guess.
WOW ! ! ! You not mention what year your burgie, new replacement bolt # 21748-10G10 that fit 2002 to 2009 is harder, read on couple of site in Europe it recommend you re-torque to 26 lb/ft torque every 1600-1800 mile and when perform oil change, change every 8000 - 9000 mile or so if it have more than small nick on bolt. They very inexpensive from Partzilla and few other on line store.Followed the advice here on the forum and replaced my bolt even though my second hand Burgman only has 4000 miles on it.

Looks awesome just hope it's not too hard and wears the adjuster end rather than the bolt. Stock they wear a little of both as shown in the photo.I didn't feel like ordering them, so I went to the hardware store and bought some class 8.8 bolts of the appropriate size and turned them to stopper bolt configuration. I increased the tip diameter .004" and increased the length .010"
Cost a buck and some play time at the lathe each.
Actually no it can't, go measure the depth. the 2010 model they machined the notch up to the bearing race (you can see it in the updated assembly, I just don't have a photo handy) to get a 2mm longer stopper bolt in there.I'm looking at your photo of the primary adjuster and it appears that the tip of the stopper bolt could extend much farther into the notch without interfering with anything.
I can't understand why Suzuki chose to have so little contact area from the stopper bolt.
I also don't understand why they chose to have a primary spline adapter that only engaged about 10mm of the mating splined hole on the 2003-2004 models.
And while I'm at it, I don't understand why they didn't make both the adjuster drum *and* the stopper bolt out of a grade of steel that was tough enough to take the stress that's being imposed on them without distortion.
That's a good question. I would say it depends on the severity of the damage to the bolt and how quickly it got that way. This one had severe damage and had stripped gears/internal primary pulley damage (keys). Up to you how it feels if you want to do a exploratory on it. I plan to do that on my '09 because it's making some belt noise like my '03 did but it could end up being normal, just want to be sure.My bike seemed to have the new bolt but had some good dings in it at 9,000 so I will definitely keep an eye on it. IF it shows signs of wear again let me ask you this, do I pull my car out of the garage for a while and pull this thing apart?
I am worried about the plastic gear also, what do they do exactly and what should we be listening or feeling for before we are stranded on the side of the road???

It would be a black color.
Please fill in you profile and location.Another good thread! Such interesting and helpful folks. Great information share and inquiries.

Simple. '03-'09 are either silver (earlier models 21748-10G00) or gold (later models 21748-10G10). The earlier silver ones supercede to the gold ones on all '03-'09 and are physically the same size.Ok, so here is just a tad of Classification I was asking for (two posts up), provided from my moto shop.
It only gives the PN for the two bolts. John at National City Motorcycle confirmed that for our '09 is the old bolt, and for our '11 is the "new" one. (see pic) 21748-10G20
The info that is missing (from my request of a Summary, gentlemen), is differences and similarities of the bolts in table format. Color, size, head imprint, etc.
