so can you agree that as its turning his lights on AND turning the bike over we can rule out the battery? the fact he rode it to work and rode it home suggest the gearbox is fine, so can we help him with sensible solutions.
psml ...Newtons Law...?where the fook does that come in the acceleration of a body is directly proportional to, and in the same direction as, the net force acting on the body, and inversely proportional to its mass. Thus, F = ma, where F is the net force acting on the object, m is the mass of the object and a is the acceleration of the object. right .. your low on fuel ? you have no reserve...BUT ,,do you have any fuel in it at all ???
John, lets get the facts right you rode it to work? you rode it home? when you got home did it just die or did you turn it off and now it just wont start? was their any signs of it dying on the way home ? was it spluttering ? were the lights dimming? was their anything unusual happening or did it just ride fine?
What are you talking about smudge? I can ride my bike for 30 miles without the rectifier plugged in? Just using the charge in the battery. Im completely lost how you think having an engine under load drains the charging circuit?
Anyone know what actually happened to his bike? Sounds like he's had a good night out is all I can gather from the random posts lol
Ha ha ha Jon. It sounds something very small , so don't be disheartened , part of biking is learning about how things work etc when they go wrong , we have all been where you are ..... I'm sure mozz will be over tomorrow to sort it .
I'd put a spark tester on it, (Alternatively, unscrew the spark plug, plug it into the HT Lead and place it against your cylinder & Turn the bike over. You should see a big spark coming from it) Make sure you don't hold the spark plug or touch it whilst doing it, or you'll get a nasty shock. Providing there is a spark, I would then look at a fueling issue, If you've run the tank really low, there is a chance it's sucked a bit of crap from the bottom of the tank into the fuel lines. I'd give replacing the filters a go, Once you've done that, I'd put the plug back in and turn it over a few times, then take the plug out and see if it's wet with petrol. If it is, and it's sparking and has fuel it could be a compression issue (But it's more likely to be fuel/spark). Do you know if these bikes have any issues with their fuel pumps ?
No one has mentioned the scrunching sound as the engine died. Now I'm not a proper mechanic like some on this thread, but Newton's other law states, "For every scrunch, there is an equal and opposite scrunch." So to me, it sounds like the problem could be mechanical. And for Smudge, very sorry, but there is NO way a tight chain can cause a flat battery! Think about it, there is no connection between the electrical system and chain, sprockets or gearbox. Even if the chain was tightened to almost breaking point all it would do is put strain on the chain, rear wheel bearing and engine output bearing. The engine would labour a bit, but the alternator would keep spinning happily and charge the battery.
