I sold my Honda CBR 929RR friday to a young man. :happy34:He called me last night and said the bike would turn over but was not getting any fire. :fiddle:He then told me that he had left the ignition switch on overnight and the battery was dead the following morning.:innocent: With the advise of his buddy, he used a car to jump the bike but while it turned over, it never started. :puzzled: He then put the battery on a trickle charge overnight but it still will not start even just on bike battery. :think: What did he mess up? Stater? Regulator? Ignition? Any input would be appreciated!:bowdown::bowdown::bowdown:

I've jumped many a bike with a car.. never had a problem... I've also jumped my old truck a few times with my bike, and also my wife's car... once again, never a problem... I'm wondering if there is something else wrong...

 

What ever happened to "sold as is"?

Sold "as-is" but just trying to point him in the right direction. Its good to know that a bike can be jumped off by a car, I have just never done it. Probably going to be hard to diagnose then...:puzzled:

He could have fried something... no telling.. if he hooked up the cables backwards at first, he could have toased something.. just hard to tell.. could even just be a fuse...

A wise man once told me to never jump a bike from car, if the engine is running. Always jump a bike from a vehicle that has the engine off, or just jump from a battery removed from vehicle. Is this good advise?

Check all of the fuses.

It doesn't matter. Cars and bikes are both 12volt systems. Some will say the amperage of the car battery will hurt the bike, but that's not true. The bike will only draw as much amperage as it needs to start.

Unless the battery was fairly new, I suspect that a complete drawdown on the battery may have ruined it. Also, a trickle charger will not charge up a dead battery.

As far as starting, since he did not have any experience starting this bike, he may have flooded it. Once flooded, he may have to replace the spark plugs.

The first thing he needs to do is make sure the plugs are getting fire.

The guy I bought my venture from tried jump starting it the day I bought it. He fried the starter which I had to replace. I verified this by trying to jump it from the positive post directly on the starter. this bypasses your switches and relays. if you don't get anything, it's fried.

I don't know what he did to it, I had the bike for 3 1/2 years without a single issue :sun1: I basically told him that it was something he did, :buttkick:still would like to know what caused it.:icon_smile_question

I think the danger in jumping a MC from a car battery comes when you let the starter run too long or too much, overheat it, and possibly damage the windings & insulation. Short bursts should be ok from the car battery.

 

I've never heard of having to replace spark plugs because of a flooded engine. If I suspect I've flooded an engine, ie: used a full choke a couple times without getting the engine to run, I just stop for a few minutes to let excess fuel work out of the combustion chamber, and off the plugs. If the plugs have lots of blackish buildup after normal running, then either one needs to adjust the carbs (jets) to get a leaner mixture, or run a hotter plug, or both.

Well, i got a very good Laugh out of that. :crackup::crackup::crackup::crackup::crackup:

 

 

But it leaves one Question. How did you come over that Thread and in such a Forum ??

 

 

It's being plastered on a lot of forums.

Well if they reversed the leads, then ALL the Electronic Units on the bike are probably " FRIED " -- Well, they are fried.

 

However, there might just be some blown fuses. I would go there first.
