KZ440 Tube to Tubeless Tire Conversion
My original 1983 KZ440 LTD came with mag wheels and tubes in the tires. For years I just ran them that way. Figuring the factory put tubes in there for a reason. Well this week I had a blow out in the rear tire. Picked up 1.5 inch nail.
So I decided enough with the old tubes and converted it to a tubeless tire. I bought a clamp-on valve stem from NAPA. The part number is 90-426 and cost less than $4. It fit right in the hole. No drilling required.
Next I bought a SHINKO 777 130/90-16 73H tire from American Moto Tire. Got a great price and came in two days. Can't beat that.
The SHINKO 777 130/90-16 73H HD is a heavy duty tire and should last me for a lot of miles. The tire is much stiffer than the tube tire I took off, so the ride is much firmer and I am only running 21 psi in the rear. Who knows, these tires might run fine with no air in them at all. The sidewall is really that stiff. I don't know if I like them at this point. Might take some getting used to them. I only put 8 miles on it so far, so I can't say much more. If it lasts longer than the 8,000 to 9,000 miles I used to get out of a rear tire, I will be happy.
I wish I did this years ago.
Oh, the front tire was converted to a tubeless tire by the previous owner. I never knew it until I replaced that tire with a CONTINENTAL CONTI GO! 3.25-19 54H FRONT. I like this tire a lot. Grips well, does not track in grooves and has been wearing very well. This one has been on the bike for about 3,000 miles.
When I put some more miles on the tires, I will report back.
