Inner tube patch
« on: December 11, 2012, 07:17:21 PM »
I'm doing a restoration/customization on a '74 750 and poked a very small hole in a new inner tube while mounting a new rear tire. I've ordered and have received a new replacement inner tube but am wondering if I should just patch the first new inner tube and keep the second one for a spare?

Is a patch on a cycle tire inner tube a no-no unless it's just to get you to a new tube?

Nah, I did exactly the same thing on my tire.  If the patch is done well it's no prob.

I would not use a patched tube unless absolutely necessary.

I patched and used patched tubes for many miles without any problems.   If you have new one coming and feel like it, put the virgin one in, but as stated above, properly patched tube is as good as a new one.

In the interest of rider safety, I would replace the tube because the bike in question is for a Honda 750. Patching lightweight motorcycle tubes are a different story. Honda never offered a patch kit for the CB750 and you were sold a new tube. This was mainly for liability reasons due to improper patching practices. If the patch covers any part of the tube mold line, this line must be completely removed for proper patch adhesion. Otherwise the patch will probably leak or fail altogether. Back in the day, just about every brand of motorcycle rider knew how to patch a tube out of road side necessity. If there is any doubt about patching when given a choice, I just replace the tube.

I'll let you know when my patch fails, 3,000 miles so far (one short season), could be a few years yet..

A patched tire on a Bike is not a good idea. The rear is more forgiving. A front tire flat you will not get out of so easy. If fact, if a front goes down you will most likely go down. A tube is what $30. My ass is worth a lot more than $30.
Wherever you put a patch you have a bump. The bump will rub and rubbing makes heat. Hot day, twisty road and plenty of throttle, you wind up on that hot pavement, maybe you get up and maybe you don't.

If it's done properly there is no problem.
 Do you all think we scrapped tubes in the 60's, 70's and 80's?
The 'can sue' instead of 'Can Do' attitude in America changed a lot of hings, not always for the better.
I always stretch tube over my knee so it's closer to inflated shape.
It should 'pucker' slightly when you take it off knee if done 'correctly'
I've used patched tubes for thousands of miles on all sorts of bikes (including 140mph Z1B)

Man, if you had to buy a NEW WHATEVER!!! just so you can go riding you wouldn't ride MUCH!!
Patch it and ride, I'd hate to be stuck on the side of the road waiting for a HAULBACK to take my bike to the SHOP to fix a friggin flat tire. Sounds like a HIGH DOLLAR rider not a 35 year old CB750.

I can't ever remember buying a new tube, probably sometime though.  Am I living on borrowed time?   ;)

I must say I have bought quite a few new tubes over last several years (got a couple of spares at present, but also have a couple of new wheels with tyres that need fitting)
I doubt any shop will patch a tube (even if they know how)

No, shops don't want to patch it, They will give some line of BS like I've already heard,  Not good, will be out of balance, will wear a hole in the tire just so they can get you to buy a new tube then pay 20 bucks to have them install it ,that is if the wheel is OFF the bike. With the wheel still on the bike they'll probably want to charge the hourly fee 75$ just to R/R , so you're now looking at about 100$ to fix a flat that you could have repaired for 5$ in a 7/11 parking lot with a pair of tire spoons!!

I've ridden MANY a mile on tubes with more than 1 patch and NEVER had a problem.

I'm with Dream750 on this one.
Heck I even replaced my 300 mile rear tire on my Goldwing this summer due to running over a nail. When you only have two tires keeping you safe, it's best to just replace when in doubt.
And, judging from you posting this question, I think you have some doubt about patching it...

You've got a new tube? put it in. use the patched for a spare. simple enough to me. If I was on the side of the road and no spare, well I would patch. A properly done patch "should" be fine but why worry about it? Most tubes are 15-30 bucks.

Patching a motorcycle tube except for a quick fix is illogical. It takes as much time and effort to patch a tube as to replace it. Not many people know the proper way to patch a tube anymore.
There is danger here also. People mistake a bicycle patch for a motorcycle patch. I have had a front go down this summer at speed and I will tell you I have never been that out of control in anything.

The experienced guys here have somewhat of an obligation to not put the new folks at risk.

Maybe you grew up patching tubes, but in the last 30 years how many people have patched tubes? Has the quality of the patches improved?

$30 bucks for a natural rubber Metzler is not much to pay when you are counting on both tires keeping you off the pavement.

I just saw a post where someone advised a guy to use an O ring chain on a 550.

I grew up patching tubes and REPAIRING pretty much anything that broke. In the last 30 years the general consensus of that generation (30 year old or younger) is , I can just throw this one away because I can buy a new one cheaper than repair this one and most of them weren't BORN with that attitude.  If it wasn't for guys like US then ALL the OLD bikes would be gone because MOST shops won't even touch them , they're afraid they might break something or since it's NOT EFI they don't know HOW to work on them!!!

Keep in mind that the majority of bikes sold in the last 20 years are tubeless.

HMMM, thats strange I have a 2000 Model Roadstar with inner tubes!!

WOW a difference between a bicycle patch and a motorcycle patch,, they're both vulcanized rubber and get glued with the same glue. I'd guess you think there is a difference between TUBELESS plug for a car tire and M/C tire also.

You'll only ever know why its dangerous if you have one fail Chuck, you ever looked at both patch kits side by side, the bicycle patch is smaller and thinner, and a bicycle won't go 70MPH. Plugs are worse, they have been banned here for over 30 years for bikes, they are plain dangerous. The best advice here is to get a new tube, especially on the front..

Yes Chuck I know. I was raised by a old school German Tool and Model maker who lived by the "if one man made it another man can fix it".

I can jigger rig with most. There are some things I will not take chances on. MC tires are one of them.

Will it be as good as new when patched?  Of course not. It's
STILL used, and is now USED and has a hole with a patch over it.
New is new. No holes, no repairs, less worry, and as other guys have stated, tubes are cheap. Your life is priceless. Spend a few extra
and forget it. Repair to get out of trouble, replace to stay out of trouble. And replace that inner strip while you're in there...
that sometimes comes with the tube. :)

Dunno,spoked wheels don't hold air very well without tubes
 OK, how many people here have bought a used bike with OK tyres and changed them just in case previous owner 'did' something?
There would be no market for used bikes if everyone spent all their time worrying about stuff
