It's happed to me about 5 times in the last year. I'll be driving along, loving life, and suddenly with no warning the speedo and tach quit working and the engine, battery, security lights come on, but it seems not to effect the way the bike run's. If I pull over and shut the bike off, then restart, everything goes back to normal. Anyone experience this? And what could be the cause?

 

I forgot to mention, There is a tmax installed on my 07 sg

 

I had the same problem yesterday. Did you get a reply on what was wrong? I also have the thundermax
