Whether your bike won’t start when it is still in the garage or it won’t start on the side of the road, one thing will always help: swearing. It might not sound effective, but at REDRIDINGBOOTS, we have yet to have a motorcycle restart that we haven’t sworn at. That’s what we call an impressive succes rate. So we swear at all of them immediately should they not start.
How much you have to swear at your bike, is situational. One might need just a little curse. One you can just whisper and be done with. Other bikes might require a bit more. So whatever road your motorcycle has chosen to quit traversing; explore the problem and start to swear. It will help, we promise.
