Warmed up but won't start?

mainlinecoffee · 03-07-2014, 04:11 PM

Went for a 50 mile cruse and bike ran fine got to final destination and now bike won't start. It's missing two fuses but It ran good. Is it possible I screwed something up or overheated?

Leave the choke on by chance? At cruising speed and at a constant rate you'd never know you left the choke on until you came to a stop and your idle was crazy high.

Does missing two fuses means they're blown or you left them out on purpose?

What does it do when you try and start it?

It dosnt have a choke,always springs to life almost instantly...it acts like it's not getting a spark but all my tools and gear are 65 miles away.

Switch to the prime position and see what happens.

When you say it's missing two fuses - can you be a bit more specific? It could be that one or more is crucial to starting. Also, you haven't told us if they're missing or blown, or if they were ok when you started your journey. To try and identify faults over the internet we need all details, and the full story.

Problem is I am not sure when they fell out. Is it possible that if they fell out when running that it would still run but not restart? It only had three fuses and three breakers, the breakers were for main power ignition and tail lamp. I am headed down with tools and spares in a bit.

That would certainly seem to be your problem!

The ignition fuse is in line with the safety switches and starter button, so, of course, it won't start without the fuse. Make sure you replace ALL the fuses before you set off, otherwise things like signals, brake light etc won't work. Also, when you get it home, check WHY the fuses have fallen out. If it's because of a sloppy fit, the holder needs tightening up, as it'll cause a high resistance, overheating of the fuses etc. and probably causing the fuses to fall out again. BTW, it's a 20A fuse in the starter circuit. Can't remember, offhand, what the others are.

Well I just checked, I have lost all power but it's before the fuses. None are blown.
