Quick advice needed before i blow up my bike!

[Darth]

It has been laid up for a few weeks and have just got it all back together again but battery is dead. Have somehow lost my charger and really want a test ride tonight. Can i jump it off a car battery or will this fry things? They are both 12V and it would only be on few seconds?? Help!

I've done it many times, not a problem.
Some would say it can damage fancy electronics, but if you don't have the car running, really can't see it being an issue.

Not that I ever have, but might be worth unplugging the terminals on the car to be sure nothing happens to the car electronics.

Although I don't know what the bike is (could be a scootay?) bump start it...

Clutch in

Ie stick it in 2nd , run with the ignition on erm ON, run to about 5-10mph let out the clutch jump on the seat at the same time to give bit more traction on the rear wheel , a small bike <500cc should bump easily , I can do it on the NTV easy in as little as 10ft.

Cheers for the advice. Tried running but i injured myself the other week and the first attempt nearly crippled me!

Its a 97 GSX600F and a MK1 golf so shouldnt think there are too many fancy electronics to fry either side!?

I thought the ECU settings were usually one that adapted to the style of riding/driving.
Jay always had a go at me when I hit the kill switch of his 675; I think I pointed out that resetting it was probably a good idea as we were putting it in a van after a track day and he'd next be using it for commuting or something.

So the vehicle learns its own settings? Just sounds ridiculous, what would be the advantage of that in the real world?

There's plenty of learning ecus about - most go back to sensible default when they loose power and just re-learn what they need. Some go into a stupid limp-home home which needs it to go to a dealer to be re-educated.

I understand that settings 'change' whilst on the run but 'learning' and subsequent retaining for the next time its run seems pointless to me. I know that ECU's adjust fueling etc for engine temp, air temp and stuff and that makes sense as every day there is different ambient temperatures, more moisture about in the air and stuff. The learning bit would need the ECU to find out what is perfect and not perfect about that particular engine and then apply it, but again that would be like the first instance where it starts fresh every time and simply adapts.

Then to go on and wipe it to a safe point seems completely ludicrous

On most cars theres a backup, When we used to do it i think its about a 5 min before car forgets the set up and then they often struggle to start for a few seconds when reconnected, as the settings are cocked up, then the ecu (being a minicomputerjiggery) sets using the sensors on the cars. The only time this is a big issue is when youve had the car remapped etc i think?, as you can chip ecu's with fuel maps etc and stick em on without being on a battery for ages and itll be fine.
Similar to car radios if your battery goes flat you usually loose all the radio stations, unless theres a backup for the player.

Interesting direction this thread has taken! When i had my skyline it was always advised to me to disconnect the battery after doing any new minor mods to allow the ECU to relearn - just go out and let it warm up and then give it a good thrashing basically. Obviously major mods required remapping.

Any ways to the original problem - jumped it. Car and bike both seem happy. Bike especially so - is much more spritely now both front calipers are free and clean!

Nice one!

Sorry for running off at an angle for a moment there
