Battery flat, trouble starting VFR750

[actungbaby]

aggh am at my wits end i replaced my clutch plates and left key on and dam light drained the battery

Know i just get 2 clicks i tryed push strating the bike i done this before in 2nd gear buts it bit nasty. but since clutch is draging

Know cause new plates its bit much by myself. i tryed jump starting from my car then my mums just does the same

cant work this out , besides getting battery charged which means i got wait till monday ,

So pevved of feel like trowing match in the tank hehe (not really ) anyone from ami insurance am only joking)

[jellywrestler]

if you're getting the same result when jump starting chances are the jumper leads etc aren't connecting correctly.

[merv]

Jumper cables should work.

You haven't done any of the "silly little things" like knocking the kill switch off or leaving it in gear with the sidestand down have you because then the starter won't work when you hit the button?

Often quite hard to physically get a really good high current connection to a bike battery so that jump starting will work.
You could buy a cheap 12V charger from the warehouse, repco, or Supercheap. These are a good thing to have anyway. If you do, connect it via a stop light bulb or similar to your bike battery for a few hours. (Bike batteries are often a bit small to take the full current.) A bit fiddly, but this should sort your troubles out.


:yes:

[ducatilover]

Got a nice clean earth, bike in neutral, clutch in etc etc?
Does it have running lights? If so, unplug the lights, should give you a bit less drain while cranking.
You haven't knocked the connections on the starter relay around have you? They need a very good circuit.

I've yet to save a bike battery once drained :angry: I have four or five old ones sitting in my garage, all stuffed

it's not hard at all to get a 'high current' connection, connect the positive first and connect it well then connect the negative to a suitable spot on the frame (assuming it's a neg earth system, as for the rest of your advice, if someone hasn't go the nouse to connect the jumpers properly how on earth are they gonna understand that dribble?

At present I have a bike with an 18 year old Yuasa battery in it still working perfectly. Several times
I have left auxilliary electrical equipment switched on for a few days & taken the battery below 10 Volts. (Yes that was stupid!)
My suggestion was largely based on these very successful recoveries, and a host of others with other bikes & cars over several decades.
You have to take the tank out of my bike to access the battery terminals or starter connection. I have done this several times but prefer to avoid it for a simple flat battery. The other problem is that although the chassis is earthed, it can be surprisingly difficult to make a really good connection to it for jump start leads. (I suspect either corosion, or corosion protection coatings here.)
Finally, if any lead acid starting battery is heavily discharged the best capacity recovery available is a long slow charge as soon as possible after the discharge. Amost any connection to the electrical system (eg via a fuse box) will work for this. Hence the suggestion to buy a charger.
I will leave others to judge the merits of all this. cheers

yes i checked those i took the battery to get it charged thanks for the reply dude , i was wondering as moved the right side coil

But more winding over thing so maybe cog byt the clutch is jamming was bit misson getting clutch housing back on i got take it of

And but some silicic gasket as its leaking so i try battery and know then if goes fine it be good

yes your right i will need to get a charger , was more the headlights been on with bike not going,Yuasa do make bloody good batterys

Thanks buddy

yes your right there i did move the coil well unbolt it as it was in the way of one the clutch case bolts good man.

Yeah usually re trace what has changed since was working, yes once they been left the batterys get rooted as get that crap build up on the

plates, but this battery been fine so think more me than the bike, i got it charged today so have to wait till collect it

[actungbaby]

if you're getting the same result when jump starting chances are the jumper leads etc aren't connecting correctly.

yeah i thought so too chould be was dark when was trying it, when tryed it of my mx5 i chould hear my car engine slow so was drawing on its alternator but still not enough power as my little baby been sitting my dad garage for months , the vfr taken top dog postion

Especially the jumper leads that you buy at the big red shed. Dead flat batterys need a dam good kick to start the bike. And needs to spin the motor over pretty quickly when push starting ... needs a dam big hill ...

I can sit on my GN and push it to bump start it :D Not so successful with the 600 though

I tried it once on my 1200. Didn't like it (me ... and the bike)

I learned the sad way that I have a huge amount of trouble pushing an FJ, even when I'm off it.
Being a weak little man is never good :facepalm: I think my bike at 200kg full wet is heavy enough

well best way is the trow your down on the seat but to hariy for me am 6.1 but yeah i have got it going push started twice b4

But not much fun

[merv]

Have you got it started yet?

[sootie]

Very seriously, the last few times I have had a flat battery on a bike, the easiest & best solution has been to put the battery on a long slow charge. Jumper leads on bikes are fine if you can get at where you need to make a connection, but unless you are going to give the bike a long run when it starts, you are still going to leave the battery in a low charge state & this is not good for battery recovery. :violin:

Of course, it helps no end if there is other transport available when you discover the problem!

Hi merv no i didnt have money to collect battery will get it tuesday get some silicin gasket rtv as dam leak

In clutch cover so i post then bikes under cover outside aghhh had bring mx5 home so its in the garage

really missing the bike sort panic as been so reliable since got it in janurary but it work out okay.

Well put my charged battery in and was same thing except made a whining electrical sound too

Panice griped me aghh then like calm down i had to tell myself well i removed the clutch case cover and was me fitting

A gear dowl wrong as i was fitting to the clutch case and i should pushed through a gear cog that drives i think the oil

Pump as gear just floats without this pinion rod so must be jaming stoping the engine turning over.

Plus main reason was spacer i put in front the cog was actually surposed to fit behind and its starter cog

So nowonder starter was jaming omg i whould not make a good mechanic these guys deserve gold medals

I managed to cut my hand ob the sharp egdes of the engine case aghh maybe this is job for trained mechanic

Of to get some petrol to clean oil of the case so can stick rtv on to the gasket to stop it leaking
