Just curious why you don't carry/use a tube patch kit?
I carry one and have helped patch 3 tubes thus far with no issues after the patch job.
(One patch was for a pinch after the initial patch was already made!)
Honda XR650L (Dual Sport)
Honda CR250R (2 Smoke MX)
Honda CR500AF (Awesome machine!)
Yamaha WR250 (2 Smoke X Country/Trail/Desert)
Yamaha YZ426 (Plated!)
