I am not sure what exactly happened.

I do know that the roads were wet.
I was going up a pretty steep hill, through a slight curve, with my 15 year old son on the back. I was going real slow, 10-15 MPH because I was fully aware of the problems I just described.

I had another bike following me (with a child on back) and 2 cars following him (both loaded with kids and wives). My buddy told me after we went down that he noticed as I was pulling out that my rear tire "looked a little low".

I think the combined pressure of the passenger, uphill, and curve caused the tire to kinda swag over to one side and maybe gapped the seal just a bit. When that happened all air escaped. All that I noticed was that the back end wobbled and before I could react to the wabble down we went.

I remember exhailing as I hit the pavement "hoo-uh!" and hearing the bike scraping. When the movement stopped I remember thinking "Jimmy (the next bike) is going to run over us!" He didnt. Everyone stopped. My son is fine barely a scratch on his foot and barely a scratch on his oposite shin. I came out much better than I could have. May knee is a little banged up, elbow skinned good, and my foot hurts where it got caught under the bike.

We were only wearing helmets and boots, with t-shirts and jeans. I was also wearing some fingerless feildsheer gloves, wich saved my right hand.

I am not sure what happened, and I know you all already know but please keep an eye on your tire pressure.

Spent the night last night getting a trailer and going back out there to retrieve my bike. It now sits on the front porch. The bike and I both look like we are "licking our wounds".

Bruises and scrapes the next few weeks, and various bike issues will remind me to keep an eye on my tire air pressure. I am still not certian if that is what the problem was. I really dont know what exactly happened.

Glad you and your son are ok.
Did you do a pre-ride check? Sometimes when we get use to our bikes we forget to do the simple things. Then it comes back and bites us.

I've started using these - valve caps that indicate the pressure in your tire. I use 30s on the front, 32s on the rear. Visual check lets you know if your pressure is ok (green), starting to get low (yellow), or you really need to address the tire (red). If anyone's interested, I can pick some up - $16, shipping included. I think they come in 30s, 32s and 34s, but I'd need to double-check the range.

Good to hear everyone's alright, especialy with going down with a passenger. And also good to hear you were going as slow as you were.

Hope things are fine with the bike too.

The headlight is damaged on the right side now, to match the left. The blinker is a bit scuffed up. I think the footpeg (acorn) and my right boot kept most of the bike off of the pavement during the short slide.

And of course the tire is now completely loose on the rim.

This was unexpected....... we'll have to see what it'll take to get my wife convinced to remount the tire...... I really need a new one, plus brake replacement, and check splines while they are in there. It was all part of my list of things I need to do. We just expected to do a few other things and have a bit more time before it was done. I think I'll have drive my truck for a few weeks. Hopefully no longer.

I picked the bike up and expected to ride it home even as I could feel the blood coming down my arm from the elbow, and down the leg from my knee under my jeans. I told my son that he'd better just ride home in the truck with the girls. Then the gawkers pointed out that my tire had no air. And I realized, I also was going to ride home in the truck.

Today soreness set in, and I realized my foot hurts. Lucky it wasnt broken under the bike, and I pulled a muscle in my leg. The slide chewed up my boot some, grinded up the eyelete holes nicely and shredded my leather boot laces.

We are all greatful that it was no worse than it was. We do count ourselves fortunate in spite of the unfortunate side of it.

Im sorry to hear about the incident man, and pray and wish you a quicker recovery. But look at the bright side, you were not speeding. Thanks for posting it man, atleast some of us are going to look into minor details before gettin on our hogs.....GET WELL SOON

When it's just a few scrapes and bruises, absolutely consider yourself fortunate. Those are all quick-healing kinds of things, and, as was said earlier, probably the easiest way to learn a lesson about remembering to do the pre-ride safety check.

I misspoke earlier, too, about the tire pressure things- they come in a pack of 4 (for a car), so unless someone wants a spare pair, I can send 2 for $8. VN750joe, I've got a 30 and a 32 left. Send me your home address and I'll get 'em in the mail to you tomorrow - might make your wife feel a little better knowing that she can check your tires before you go out, too. :smiley_th

Thanks a ton Cindy! You really are great. You can sell em to newvn750owner. I still need to decide wich direction I want to go with this bike. Because if my wife doesnt want to ride her own I'll have toget something bigger. I wouldnt want you to send me parts when I still dont know how long I will be keeping the bike.

Since she's seen me go down on it twice now, I doubt she'll be interested in learning to ride at all.

She may get over it and learn from your mistakes. :)
When I had my accident in 93 (car pulled out from a side street. I hit it doing 45 in a 45 zone) my wife (well, we were dating at the time) came to the scene as the medics were cutting off my shirt and slicing my pants to check for any injuries. I only had a broken wrist and a few scrapes. After I healed and got a new bike, she still went riding with me. Now she is looking into getting her own license.

Yeah, I always wanted her to be my riding buddy. And she was into it at first. But never really on fire or hyped up about riding. And now I know she's worried about wether or not she can do it since she's seen me wipe twice. I wouldnt want to push her into riding if she isnt sure so I am just giving her time to decide for herself. If she does want to ride, we'll probably keep this bike and get another one. If she doesnt, then I'll need something bigger to haul us both on.

Some bikers love to ride. Some only want to be passengers, and some just like to look at the bikes and shop for outfits.

She never really talks about bikes. I dont push her but I get the feeling she's not really interested. I on the other hand, cannot stop talking about bikes, and gawking when somone rides past.

I'm bummed out that I have to take my truck to work today. I dont hate my truck. I just love to ride, and now I feel wierd in my truck.

If you want to minimize healing time for that road rash, use Tegaderm bandages or equivalent. They're expensive but they work - I know first hand (first arm and first leg for that matter). Also reduced scarring a lot. Make sure your tetanus shots are up to date too.

The idea is not to let it scab up. The bandages seal in the "juices" and keep the area moist. The process is messy because the bandages get full of liquid from the weeping wound and it will find it's way out at the low gravity points, but only in very small areas and the badages will stay on. You'll need to wrap in gauss to catch this runoff and change daily at first.

I know it's a little late in the process for you but here's what I did:

1. Clean the wound thoroughly to get out all foreign debris and skin that's barely hanging. I used soap and water and my hand, a sponge or lufa is good.
2. Douse with Hydrogen Peroxide. Some say antibiotics can interfere with the healing process, so you'll have to read up and decide for yourself, it just seemed like I needed to do something for infection so I did. At least use a .9% sodium chloride solution, a spray bottle works great.
3. Scream liberally.
4. Spritz wound with sodium chloride. Not too painful, but repeat from 3 if necessary.
5. I covered the whole wound with neosporin, again another antibiotic so you make the call.
6. Dry around the perimeter as much as possible.
7. Apply tegaderm bandages with about an inch border around the wound so it has dry skin (and hair) to cling to. The bandages can be overlapped if the area is larger than a single (3x4). They cling to each other great and form one large bandage.
8. Wrap in gause making sure to add a little extra room on the downhill side of the wound since that's where the fluid will escape eventually. If it's your arm it might depend on your job and what position your arm is in most of the day.
9. Repeat from step 4 daily for the first few days. You'll be able to keep the bandages on longer once the wound starts to heal, even though it's still weeping. Tegaderm can stay on for up to 7 days if you can keep it fairly clean. The whole process took about 2.5 weeks for me. Probably went through 6 boxes of tegaderm bandages at $8 each.

I'm not a doctor! If the wound is serious see one. My leg wound covered the outside of my lower leg in an area about 4" x 10" and it was raw. My forearm wound was about 3 x 6 and equally raw, both wounds produced a mixture of blood and lymph but no lacerations, but plenty of tar and grit embedded. I was wearing shorts and a tee shirt so this was direct skin-on-road action. I won't debate the wisdom of proper riding gear.

Lots of info on the web of course. I just googled "road rash" and went from there. I'm sure there are a few stories in the archives here as well but I haven't looked. Maybe we should start a new forum topic?

Good luck!

Please check the make of tyre and the recommended pressure because 32 seems a bit low. I have avon venoms and the recommended pressure for the back is 36.
I am really glad you both walked away. Please bear this experience in mind and consider getting proper m'cycle boots, leather gear and leather gloves. You can get the stuff off ebay for a bargain- it doesn't have to cost a fortune.
God forbid there should be a next time but it will be for an equally unexpected reason that you don't see coming. My pillion can't understand why I insist on wearing leathers when he sees others riding round in trainers, tee shorts and even shorts. Please do not underestimate the risks.

One caution on the valve stem pressure caps. Fritz up in Minnesota is at least one I know of that had them leak on her and she still ended up with a low tire that got sguirmy on her.
30 and 32 pressures are only good for the stock tires I believe. Metzs run higher pressure. I know my back tire runs 40.
Luckily before I left Kentucky Lake and the Gathering we checked mine and I was low. As luck would have it, JD was the one that suddenly lost air in his rear tire. I saw the wobble, pulled up beside him and pointed to his back tire.
In his case the angle valve stem had finally taken enough of the air buffeting and had torn away a bit at the rubber base (Another note here, get the all metal valve stems, ANY rubber base one will eventually wear).

It was a definite learning experience, replacing a valve stem while you are on a trip and it's a Sunday morning.

If you or someone else happens to "think" the tire looks low, check it!

That's a great point, Dianna. The caps have to go on all the way - they're tapping up against the inside needle of the schrader valve to release pressure to measure pressure.... ergo, put the cap on without cinching it down, and it oughta be in the red in short order.

I didn't know what about the Metzlers, either. Folks have always told me, "Don't go by what's on the sidewall." But...maybe we can compile of list of what folks are riding and see what the recommended pressure is? That's alarming, 'cause I think I have Metzlers on McKnight...

I think most typically run 40 rear and 36 front in Metz 880.
When you change tires you need to look at the manufacturers suggested pressures, not the OEM stock. Also note that most tires post the MAX LOAD for tire pressure. Unless you constantly run max load on the bike you want to go below that a little.
Wear and ride will also tell you if you aren't running the right pressure. Cupping, squirming, mushy turning and braking are all indicators of the wrong pressure.

The pressure printed on the sidewall is the maximum pressure for the tire - not necessarily the "best" pressure. You'll get better traction if you run less pressure. But if you run your pressure too low, you risk having the tire break loose from the wheel. Because of this, when you carry more weight (like a passenger) you should run the pressure near or at maximum. But when you ride solo, you can bring that pressure down some and have better handling.
-----------------------------

I think THIS may be what happened to me. I weigh about 260, my passenger is about 110 I guess. We were going up a steep, wet hill. So All of the wieght, even most of the bike's weight was on the rear tire.

I think I could sacrifice a bit of handling for the security of knowing that my tire isnt going to do this agian! Since I am heavy, I'll be keeping the PSI closer to max.

Thanks for the link D! :smiley_th

Brought my bike home today from the shop.

New rear tire.
Like new front tire.
New front brakes.
Rear brakes checked out fine.
Splines cleaned and relubed.

Speedo isnt working. I put a new cable on it shortly before I went down. The outer shell of the unit itself has busted loose. Perhaps it's broken? Perhaps somethign is loose inside there I can put back together?

I am hearing and noise from the front wheel I never noticed before. Possibly some of the rough tread wearing off the fornt tire till it wears even and smooth? Perhaps something inside the wheel hub that wasnt replaced problerly and now I am hearing the bearings or cable sinning freely because it isnt connected properly?

The bike is definately handling different, probably better, I just need to get back on the road I think. I have not riden in 3 weeks since I went down.

Oh, and all of my instruments are loose, shakey and noisey now.

The bike seemed to running a little strange....... but it has not been riden since it went on it's side.

Tapping noice I thought was ACCT, mechanic says he's pretty sure it a bad valve.

How long can I ride it with a bad valve? I know you drive a car forever with valves tapping.
