Bump start technique?

[zerocool]

My GS decided it didnt have enough battery to start today, mostly due to a busy month at work and me forgetting to turn off my ignition when im stood at the side of it testing bits of electric-trickery.

So I hollers Mrs ZC and say "giz a poosh"

Anyways, Mrs ZC got me up to speed and the bike just came to a stop.

So after hollering the neighbour who pushed me to the top of the hill, and down the hill in 2nd it just fired but still came to a stop rather quickly, and again but this time the rear wheel skidded in a very impressive straight line down the road.

So..... after getting to the bottom of the hill I thought back to my childhood and bouncing the rear end of monkey bikes on a bump start to get them going.

I gave up at this point but it got me thinking, is there a better technique???

Way dont you charge the battery

Make sure that you have the ignition on!

5th or top gear.

Bump Start

Make sure you're standing and come down, feet off pegs quickly onto the seat at exactly the same time you drop the clutch; of course if it's cold, make sure choke is on.
Needed this coming back from Portugal

ITs hard but do'able. I prefer to do it in 4th as fifth is very very high and it wont like it unless you are very quick with the clutch. Of course its much easier if you have a hill at your disposal. I had to do it on the flat on a sodding rt. Gs is a little easier... but far from easy

I do like the way you got your mrs to help though! Very impressive... mine would just laugh at me..

If the battery is flat surely bump starting it wouldn't generate sufficient charge via the alternator to prime the fuel pump and injectors

Jump leads are your best option - your car battery would have done the job.

Ton of respect for Mrs ZC from me too

There has to be sufficient battery to charge the fuel pump - I had a problem with a battery a few years ago and it always primed the pump but failed to start the bike - THEN ...

[THIS IS IMPORTANT - DON'T DO THIS BIT AND IT WON'T WORK] - BEFORE you move, put the bike into gear and then pull or push it BACKWARDS until it locks (won't move) - this sets the stroke or something technical that I can't remember / am too stupid to understand).

Then push, push, push up to a trot, and "seat bounce" your butt off the thing while dropping the clutch (and pulling it right back in again) after about a bike length of forward movement - it will usually start.

As I aid, if the battery it completely gone then it probably won't work, but if the headlight comes on, you've got a good chance.

By the way, RESPECT for getting the wife to help - mine would have told me where to stick it and reminded me that a bike is 'only for one person' and how selfish I am for having bought it in the first place - forgetting that her car (IS 200) was bought by me ...

Your all doing something wrong, tell her your mistress would push you

 

[zerocool]

:lol: @ at the mistress.

I wouldnt have thought I would have had enough speed to get the engine going in 4th or 5th.

The lights came on, fuel pump charged all be it a little slower than normal, and it just clicked.

I would have charged it but I needed it there and then.

How do you guys jump start it???? The battery terminals on the 1150 are under the tank, you must have the smallest jump leads in the world!!!!

1150 doesnt have choke, just idle advance, surely that wouldnt have made much difference as I was throttling on myself.

Still, I took the Mrs out on the R6, not only did she attempt to push me but also endured the cold and rain for my pleasure, she got pie peas and chips in Matlock as payment for her hard work.

 

[vilguy]

what a woman! haha

The throttle advancer gives it just the right amount to hold at idle whilst cold.

For the jumpstarting you do need some slightly smaller crocodile clips, the alternative is to strip the cable on one end and just kind of bodge them against the terminals whilst someone else starts it... not that i would ever have done such a thing

With the 4th & 5th gear thing, you have to dump the clutch then pull it in again. Yourll get the knack of it

Maccy bath.. woohoo! Price of chips is a bit steep there though isnt it. But that ice cream parlour makes some good stuff.

Try fitting these, - you can then connect to your car battery for a less strenuous start, or even start someone elses bike for them.

Jump Starting:

Take the plastic starter motor cover off then put the live jump lead onto the battery terminal on the starter solenoid.

Earth the neutral jump lead to the engine somewhere (preferably a non-painted bit).

It saves taking the tank off.

The 'Adventure' models have an insulated live connector mounted on the starter solenoid that protrudes through the starter cover. They also have an earth connector on the rear of the nearside cylinder head. Makes jump starting very straightforward.

Well mine does anyway ('04 1150 GSA).

ye should try bumping a Guzzi - now THATS fun. not!
...and Mrs Og would always help me.

prop the tank

I have a nylon bar that I use to prop the tank if I need to jump start it. Just undo the bolt holding the tank down, lift the rear of the tank and the bar fits under the rear edge of the tank, and sit on the air filter cover. (Just like a bonnet prop on a car.)
It also doubles as a good axel remover bar for the front wheel. I zip tie it to my crash bars so it’s on the bike all the time.
But I like the look of those nippy normans jump leads.

lol.. i remember trying to bump start my aprilia last winter. Even in 6th it would just lock the rear wheel. This was of course all the way down the hill.. with the not so jolly push back up to the top...

That was exactly my concern, we have a big hill and a small hill, we only tried the small hill.

That jump start lead looks the business.

The advice on the jump start from the solonoid sounds good too, any pics to support the correct positive connection point?

Well, erm, I mean ...
