popped rear tire (was klr650 2nd radiator)

Boy, I guess this is what happens when you turn your attention to snowmobiles for the winter months, you come back to the list with a legitamate KLR question and get ignored (sorry not as technochemcerebral as cycanide stoichemtry, or as titilating as the biker girl's posts, ot whatever is going on with the radiators, but hey I intend to flip my rear sprocket. really Has anyone else done this? seems to make sense to me as long as all those nuts break free without incident. thanks in advance for any input, todd Team, last fall I investigated my sprocket situation. A16 app 7kmiles. The front is beginning to show signs of wear (tooth groove beginning to hollow out). Rear looks good still. ( 3 times more teeth) Intuitively, if one could flip the front you would have a fairly new surface to put many more miles on. Nut a few on this list directed me away from this as the hub of the front sprocket has a "shoulder" it technically is not symmetrical and thus not "flippable" BTW, others disagreed and stated that they had flipped in the past (haven't we all??) One explanation for this disagreement might be that KHI has indeed changed this peice part over the years? Some years take a slightly different version than others??? perhaps someone closer to the facts than I can comment. Anyhoo, I bought a new front ( 15t its on its way) and now just wanted to verify with the experts on the list that indeed the rear (45t) is flippable?? that seemed to be the consensus last fall. I intend to dig in to the project before it gets too warm here in mINNESOTA. Might start thawing tomorrow. By the way A16 fired right up even though it had sat in the garage since October. It seems quite happy now. me too. thanks for any and all advice, Todd in Chaska A16 06 CF 700 efi 02 600 triple

I flip it, no problem. Just do it earlier than later, i.e., as the hooking of the teeth just becomes noticeable. Mark

<><><><><><><> <><><><><><><> todd, Sorry about not replying. I remember your post but got caught up in some other stuff. When I was looking at some KLR maintenance notes the other day I see where I said I had flipped my rear 46 tooth JT Sprocket two years ago. But somewhere deep in my memory I recall deciding to replace it instead of flipping it. Either way that was when I installed a new chain. I think Bill Watson flipped his sprocket a few years ago. Maybe a search of old posts would turn up the info he provided. I'm guessing it was two or more years ago. I've run my front sprocket both sides to the countershaft. But I did it by mistake. I think it will throw off the chain alignment just a tad. You'll have to decide if that's right for you or not. When I changed my rear sprocket I used a torque wrench to tighten the 6??? nuts. One of them just didn't want to tighten after I thought it should have. So I took it apart again and checked. The stud was cracked. Instead of ordering one and waiting a week I bought a longer bolt and made a stud. I think I did two as one other also looked suspect. I removed the old stud by double nutting it and turning it out. I don't care to put visegrips on stuff if I can avoid it as they often slip or cause other problems. The stud as I recall has threads on each end with the middle bare of studs for about 1/4" or so. That's where the sprocket contacts it. So I cut the bolts to length and then cut new threads to get what I needed. The new studs worked well and everything tightened as required. Probably took two hours since I had to go to town to buy the bolts and then make the studs. Hope this is helpful.

C/S sprockets are cheap enough to buy a new one about halfway through the life expectancy of the chain, if needed. By the time my rear sprockets need flipping, the chain needs changing, too, so I have just replaced everything at once.

Should work. Unlike front sprockets, they're symmetrical. But really, rear sprockets are cheap enough that unless you're in the middle of a round-the-world trip and just can't get one, there's no reason why not just buy one.

That is correct. If you "flip" the front socket, you will find that it is too far in towards the engine crankcase and no longer in line with the rear sprocket. This will cause rapid wear of the outside of the rear sprocket and inside of the front sprocket as well as rapid wear of the chain. _E

There are those who would consider it an unneccesary expense, but I try to always replace the chain and both sprockets as a set. Michael -- "Tragedy is when I cut my finger. Comedy is when you fall into an open manhole and die." -- Mel Brooks San Francisco, CA

Michael, I'd consider it an "unnecessary expense" (I believe Bill Watson would, too). I replaced my front sprocket some time ago, still have the OEM rear AND the ORIGINAL chain on, at 45,000 kms (27,900 miles)! It's been adjusted only a few times (4 or 5???) and is cleaned and lubed with WD40 RELIGIOUSLY. Cheers, Ed

I don't doubt you can do it. But I really like the smooth running feel of new sprockets and chain. -- "Tragedy is when I cut my finger. Comedy is when you fall into an open manhole and die." -- Mel Brooks San Francisco, CA

Hi Scott; Yeah, a couple of times I had something like that happen. The first time it wasn't a big deal. I had just taken a long sweeping uphill offramp from I-80 in the SF bay area when the rear end started to wobble. I completed the exit then called my wife to come get me in the pickup. The second time, I was taking a downhill offramp from the freeway at the north end of the redwoods in California. Two up with camping gear aboard and, when I started braking, the bike starts shaking it's head like a ticked off brahma. That time my towing company sent out a truck which took us almost two hours north, two hours to fix the rough spot in the rim that wore through the tube and replace the tube, then two hours back to where we were. Drats. Set up camp in the dark and didn't have all the time we needed to see the redwoods like I had promised Honey. Oh well, we got to see most of them, God rest her sweet soul.

Being that there is a truck right behind me, I start thinking, "Oh no, I am going to share the fate of the poor scooter rider that was smeared by that truck!" . [Non-text portions of this message have been removed]
