low pressure leak? - patches

[Robert]

UPDATE. I pulled the tire off and the tube out. Both the patches looked to have held bonded perfectly. I aired up the tube the size of a football then used soap and water but found no leaks. Maybe it was simply the valve core, but I think I checked it. I want some thick gas that will not leak.

Who wants to tear the wheel down a second time because the patch didn't work? Not me. I actually have 3 tubes in my back case. Or run those new little tube thingy's that you run with tubeless tires. > > Criswell > > Sent from my iPad > > On May 9, 2012, at 12:27 PM, SniperOne wrote: > > > Speaking of patches...does anyone remember the old hot patches that you clamped to the tube and set fire to the compound in the metal cup on the back of the patch? > > > > I haven't seen those since I was a kid riding in the thorn bushes...but wow did they stay stuck to the innertubes. > > > > If they're still in production, anyone know where to get them? > > > > Randy > > > > Sent from my Verizon Wireless Phone > > > > -----Original Message----- > > From: Ron Haraseth > > Sent: Wednesday, May 09, 2012 8:47 AM > > To: DSN_KLR650@yahoogroups.com > > Subject: Re: [DSN_KLR650] Low Pressure Leak? > > > > Sounds exactly what I encountered last early fall.
