Tubeless conversion options

Twin rim locks with two tubes?? How do you get all of that in the tire? I haven’t used two rim locks for forty years but rarely ran less than 15 psi offroad in rocky, tube pinching Missouri single track.

Haha yeah, it’s a bit like that. I ride in similar terrain here, lots of rocks / creek beds etc.

I run a UHD inside an old UHD (cut around the inside radius and remove the valve), it all fits inside a 140/80 e09 or Rall Z. The Mitas has a slightly firmer sidewall and carcass, making it a bit trickier. But I find the trade off is better low pressure stability at higher speeds.

I ride 20-30,000 miles a year and have a flat every 2-3 years. The last tubed tire to go flat was on my KTM 690 rear tire almost three years ago……rode it with a flat rear tire more than 20 miles to my house as the tire was worn out anyway. I was able to ride it around 40 mph in little to no traffic in the semi rural area I live in.
My friend had a puncture on his tubeless rear Triumph Tiger tire last week…..we tried to plug it with his Stop and Go plug kit with minimal success and I eventually rode home and came back with my truck/trailer to transport the bike to my house for the last 12 miles. It is the second time friends have used the Stop and Go plugs where they were ineffective. I carry ordinary string plugs which have worked great when needed. A Nealy kit works great.
I am about to mount new Shinko 705s on my T700 and am undecided as to whether or not to seal the rear rim to make it tubeless. A friend gave me the 3M sealing tape for the job, but I will probably go with a tube. I do have 15,800 flat free miles on my T7

Well, I spoke too soon.........caught something in the rear tire today and rode 10 miles with a flat rear Shinko 705 to my house. The tire had 8900 miles on it and was going to be replaced shortly anyway. It was an easy ride and the Shinko never hinted about coming off the rim.

Update…..the flat tire and ten mile ride destroyed the tube and rim strip. I learned something new today as the rear rim strip is a Herrman’s style rim strip which is common on bicycles. BUT, two things happened as the Herrman’s style rim strip lists for around $50.00!!!! and my local Yamaha dealer said they had never sold or kept one in stock. I bought your normal 18” 50mm wide rubberized rim strip, installed it, the tube, a new Shinko 705, and went for a trouble free 80 mile ride
