How to change a Valve Stem the easy way 

Your trick did it for me, on a much wider tire, which was tricky. Getting the stem in place wasn't easy, pliers are definitely needed. Tip: add strips of electrical tape to the rim to avoid scratching it, especially when using the pliers. You forgot one very important step: you need to use soap-water in order to properly seal the bead. Simply apply a very soapy solution around the bead with your fingers, make it nice and wet. Dish soap is perfect for this. Thanks for the vid, helped a lot.

Old post but I’m glad this was here! I was riding TO work and the front valve stem started leaking rapidly. I rode probably 10 miles on my bike flat. I thought my steering head bearing went loose when it happened. I mean, in 40 years I’ve never had a front flat. Aired the tire up at work ( I carry a battery powered air pump from Walmart and a tire kit in the saddlebag of my 2021 Kawasaki Versys 650.) Seemed to hold air until I left work at 8pm that night. Almost instantly it went flat. I stopped about halfway home (25 mile ride!) filled the tire. No real help. Basically rode home doing 60 mph leaning to the back of my bike. Some people might think that speed is crazy but the slower you go the less stable the bike. Coming to a stop is a knuckle biter! Went to Harbor Freight next day and bought three of those clamps just in case. Tried last night but couldn’t seem to break the bead. This morning I thought I’d give it another try and use three clamps… POP! I think the hardest part was getting a socket on the back of my new valve stem. Just rode the bike. Holding air. No damage to the tire! No damage to the rim because even though I was going fast I was very careful around turns. It’s a bit out of balance. The bars shake a bit at low speed. But I have Ride-On in my tires so I’ll just add some. Probably lost some or it dried out riding home on the flat. Thank you for the video. Saved me a couple hundred dollars.

I already had this idea to try except I was going to use a C-clamp but my front tire is old and I was afraid I would damage my tire. (I am going to replace it in a few weeks but I need the scooter now) So, I saw your video and then ran to Harbor Freight and bought a 12" bar clamp like yours for $3.99. I just completed installing my new valve and from start to finish it took 6 minutes or less! I wanted to thank you for your brilliant suggestion of using the HF clamp. It is PERFECT for this job and now I will have it around for other jobs too. Thank you so much. No tire damage at all because those rubber feet on this clamp are just right.

Great video make more please. Very straightforward straight to the point that's what I like.

What a great hack! I just changed my stem on my honda metro in 5 mins

Worked for me on my 1800 Goldwing but had to initially use an 8" C clamp to break tire rim seal. Afterwards the two flimsy Harbor Freight clamps did the trick.

Brilliant idea! Harbor Freight Tool, here I come~!

Thank you its very smart your video was very helpfull , My tire 120/70 R 17 I use a 4 inch clamp I use a rubber valve at the end i pulled it with vicegrips and click no problems

Great hack, just tried and completed it this morning... had to use 2 clamps to break the seal.

My tires a tube tires but I want to go tubeless and this video helped me out.

Thanks for the video, I was told by “Canadian Tire” staff my electric scooter 🛴 Navee N65 valve was the issue for the flat. How do I measure the valve to order the right size? - my operators manual gives me no measurements for my scooter valve; it’s only 6 months old - (annoying)!! Thanks so much😊

Kman you're a genius thank you! The best hack I've seen for this job on the web.

Cool video. I have a rotton stem on the back tire of my yamaha R1. Not a scooter but this is good info. Thanks

do what i did i rod it home on flat slow soon as i when to make a turn into the naborhood the beed broke off i almost crashed but i know it was comming so i had both feet down to catch myself befor it almost crashed sidwas then i got off it gave it little gas to walk it home eazy cus my house was right on the corner but i had no strap so oldschool with rope and a tool twisted the rope in the took for a seal and we good

I just picked my tire up from the repair shop, they charged me 75.00 for this. To bad I didn't think of researching it before I took it to the shop.

I haven't been able to find those stems - where do you get them? Great video - thanks!

@kman auto what size is your clamps

Thanks man!

Excellent

Dude! you have a Cacoon dangling from the rear of your front fender!

hi, does the front wheel need to be lifted to do this? I tried using a clamp to do as you did but since the tire is flat and sitting on the ground, I think that is preventing me from squeezing the tire enough to break the bead.

@Kman Auto I have a crotch rocket so do you have to have motorcycle stands in order to do this

@KMan Auto will the stand/lift you're using work on motorcycle's and if so what is the name of the brand you used or what kind should I get for my crotch rocket front and rear stands or the one your are using

Can i just inflate the tire after this and ride?

what brand rim stem do you use?

If you don't break the bead, you can damage the sidewall clamping it. Ask me how I know. 😅

Why did the guy at the tire shop tell me I have to get a new rim and he was totally stumped as far as replacing a valve?

Weird a trailing front axle

What scooter is that?

I don’t know what size to get

who makes that 90 degree stem?

Tried this with motorcycle. Did not work

Yo mo videos

Problem is the bead will never set unless you have a super powered compressor.
