Who has sealed spoked rims to run tubeless?
« on: April 04, 2020, 05:55:01 am »
I picked up the 2018 base model spoked rims for my Bolt a while back and am thinking of going tubeless. I really dig the retro look of spokes but prefer the safety of tubeless tires, especially for longer road trips. Just wondering if anyone has experience with sealing spoked rims and compatibility with tubeless tires... specifically with the lack of "safety bead" on the spoked rims. No theories please, only looking for answers from those who have actually done it and ridden a while on sealed spoked rims.
Hope you're all doing well, Cheerio - J  8)


PS: For those of you wanting to get spoked wheels, if you order the rims/hubs from the newer base model they'll cost much less than the "Custom 40 spoke wheel" Yamaha offers at $800 a pop... The front wheel set up only cost me $450. Plus the hub on the new base model is smaller and (in my opinion) nicer looking. ;)

Bedhead, Are you looking at doing something like Outex tubeless kit? I have no advice for you that would help, Just wondering what your plan is to start? Iíve also thought of doing the same.

I'm planning on doing it this year.  I ran a few years with tubes in my spoked rims, but also want to go the tubeless route. 

After some research, I bought the Outex Tubeless kit , Part Number FR-BO2535  for the Triumph Bonneville 790. The only difference in tire size is that our rear tire is 1" smaller in diameter, giving about 3" extra tape for the rear. Fit's the purpose perfectly!  It includes the tape, gloves, Valve stems (that fit the different sized hole for the inner tube valve), and everything you need, except a way to support the rim, and a heat gun (not necessary, but recommended).

My only problem is that I had previously tried to seal up the spokes with an aviation sealant (PPG's PR1422, commonly called PRC).  This stuff sticks like Crazy Glue could only imagine! And it can make a mess like a 2 year old with a bucket of silicone sealant! We used it to stick stuff to the OUTSIDE of Helicopters and F-18's!  And I had put it around EVERY spoke end!  It's NOT going to be easy to get the stuff off so I can use the tape in the Outex kit!

The Outex kit is shown in several Youtube videos (search for Outex Tubeless on both Google and in Youtube) and should be easy to install (AFTER I get the PRC Sealant of my rims!).

For balancing, I'm going to use Dynabeads, or something similar. My wheels have them, now and I love them!

I've read a lot about successful DIY jobs. On the Zero, I wanted to do it with silicone, a narrow rim band and the clear Gorilla tape but too many set backs made me just want to get the wheels on and ride. Go for the Outex if you don't want to experiment.

Back in 1985 honda made a spoked tubeless rim - Honda rebels from those days had them. There is a lip in the middle that takes spokes. Inexcusable that Yamaha did the SCR etc with tube tires cos the spokes punch through the rim.
Anyway I like the tube tires with trailwings just fine.

Cool.

Quick update on sealing my spoked wheel...
So after a ton of research I found out that the rim of the newer spoked wheel ( the one offered standard on the more recent base model Bolts, not the Yamaha overpriced "upgrade" set) has just barely enough of a bead retention lip to run a tubeless tire on it. I contacted a couple of local companies about getting it sealed, one said they couldn't do it, the other said they could... The company that said they could mostly converts super-bike rims (and stunt bikes) and has a better reputation so I went with their advice regarding if it could be done or not. I had thought about trying to do it myself but the possibility of a front tire blow-out made me decide to ask some pros instead. Here's what they did (see pic below)... apparently it's a multi-layer system but that's all they told me. I've been putting this set-up through the paces for over a month and my tire pressure is constant. Very happy with the results.

Julian:
That looks EXACTLY like what the Outex kit looks like when it's installed! And the Outex system is 2 layers of special (and different) tapes that make the seal around your spokes, so it matches their description, too.  And it's good to know that it DOES seal.  I'll be doing my own as soon as I can. 

I'm getting a bunch of projects done during the lockdown, but since our weather is crap right now, and my primary vehicle has a dead starter, the bike wheels aren't top priority at the moment - I NEED the bike, even with the cast wheels. Hopefully I'll be able to get to it in the next couple weeks, especially since I have to do my brakes, too.

Thanks for doing the research about the bead retention lip! That alone is PRICELESS information.  When I get my tires off the wheels, I'll compare them to your pic and let everyone know about those "Yamaha overpriced "upgrade" set" of spoked wheels!  ;D (unfortunately, I do have to agree, but they were the only ones available when I bought them ;) )

I also replaced the spokes with stainless steel ones... Seems the standard Yamaha ones are made from recycled Honda civics from the 80's LOL... they rust if you at them sideways ;)

Julian, your tank graphics are very similar to the blue '77 RD400. Is that just a coincidence?

Throw a darkside rear car tire on that and a back wheel only drum-brake system and you've got a real winner LOL. Safety last, right?!? Maybe it'll work fine, but why tempt fate? Just sayin'...
