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.

cheers,

These bolt pictures should be made as a sticky as there are many threads running with pics in them and it would be nice to have the pics all in one spot.
Or even 4 pics with new, perfectly fine, replace now and OH SH*T

Heres the one I added to thinking IT was the one.
Primary pully stopper bolt.

Oct 2015 purchased 2007 Phantom Grey Metallic AN650 - 7000 miles
Feb 2016 and have done more miles in 5 months than the previous owner did in 8 years.
Mar 2016 3 MC tires in 17500 miles then went Darkside - Federal Formosa FD1 165/60r 14 - now 8000 miles in and finding it far superior to the MC tyre's.

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.

The '11-up models use a black one (21748-10G20) that is approx. 2mm longer than the previous ones.

The silver/gold and black ones are not interchangeable. Earlier models ('03-'09) can only use the longer black bolt if the primary pulley assembly has been replaced with the updated one (comes with the new assembly). I have in the process of rebuilding the CVT on my '03 installed the updated assembly/stopper bolt and strongly recommend it to anyone rebuilding a CVT because of the improvements to it.

Refer me to a link so I can see where this bolt is located by a picture. My Burg is a 2006 with 4500 miles on it. Any problem do you think? Thanks

MOS1, this is the CVT stopper bolt and is located on the right side right under where your heel rests on the floor board.

But on a 2006 and it seem only 2006 there is another bolt that needs attention. It is the primary adapter bolt. It has no thread locker and can loosen up and rattle around for a while till it busts thru its cover. The the CVT splines can strip causing major $$$ in repairs. For the cost of removing the bolt, cleaning the threads and a drop of Lock-Tight and re-torquing it down can save a bike. I will try to find a picture of it too. It is just to the back/rear side of the oil level site glass and the cover has two small bolts holding it on. Check post #3 of this topic. What is this?

Read that one and this one to see: 2006 Primary Adapter Bolt issue.

At which model year is it safe to stop checking the stopper bolt? One would think Suzuki would have resolved this problem by now.

Stopper bolt SCHMOPPER BOLT it doesn't matter !

Stopper bolt SCHMOPPER BOLT it doesn't matter !

The bolt is not the problem , the design of the CVT is the problem . A banged up bolt to one degree or another is a sign your primary pulley is experiencing problems . That means this CVT's days are numbered to one degree or another . Some still think that keeping an eye on the bolt , and changing it when it gets banged up is a cure . All that will do is POSSIBLY delay the inevitable a day a week or a couple of weeks ......MAYBE !!!

Every one has heard the horror stories about the $4,000 dealer repair bill , and the 6 months it took them to do it . And they've heard about the rebuild that went bad a few days later . It doesn't have to be like that , as long as you are willing to get your hands dirty .

I've parted out several of these bikes now ,torn a couple of engines completely down to splitting the cases . I've torn several CVT's apart and have rebuilt 3 , and have come to some conclusions . IMHO the best way to go $$$$ for most , is when the blessed day arrives is find a low mile CVT off a wrecked bike . Then do the quick method of replacing the entire CVT . Around $500.00 and a days work for most , will get you back on the road .

If you want to keep your 650 Burgman for a long time , you would be much better off to quit looking for a magic bolt and start looking for a low mile CVT . There is no magic bullet , no easy button and the Burgman 650 is what it is . Except for a longer stopper bolt and a couple of extra keys on the primary pulley shaft , the new CVT is just like the old CVT . Will the new one last longer ? The answer IMO is maybe and maybe not . I recently pulled one of those "new ones" apart and found that who ever built it at the factory , didn't use enough RTV on the primary pulley O-ring . The result was the O-ring slipped out from under the shim , the vibration wore a groove in the case (case ruined). It destroyed the stopper bolt , and did considerable damage to the female side of that stopper bolt slot in the primary pulley . In other words in this CVT the NEW STUFF made NO DIFFERENCE !

Is there any thing you can do as far as preventive maintenance on the CVT ?

Not from the outside . If I had my bike apart for some reason , I would pull the CVT apart and clean it up and check it out for wear . I would FOR SURE replace the primary pulley O-ring and use RTV all the way around it . Then before putting it back together I would let the RTV cure for at least 24 hours , or even longer because it is so critical that it stay in place .

Every machine ever built has weak spots , whether it be a car , a bike or any really any thing mechanical . In other words this phenomenon is not Suzuki specific , overall I give Suzuki high marks for the Burgman 650 considering the price they sell for . And the fact that you can buy a low mile used one in the $3,000 range , IMO is a gift from the scooter gods . There are a few annoying things I don't like about the 650 Burgman like the CVT , but there are many many more things I love about these bikes .
