Re: What is this and how do I make one...
maybe you should save your money and learn how to bump start a bike instead. if your battery has gone flat then you have either left your side lights on or your battery/charging system is fubar. if the battery has gone flat due to leaving your lights on then a bump start should get it going again, if its the battery/charging system then jump starting it from a capacitor or even a battery is not going to get it going.

Re: What is this and how do I make one...
That capacitor would never start a bike but may have been used a a smoother on vehicle electricity circuit to take any ripples out. A bank of them may start a bike but it would need a few that size connected in parallel - that blue fuse looks like a 60 amp 'maxi-fuse (blue).
If a bike has a duff battery it may run if you put a capacitor in to replace battery and bump start it. see last post on this forum http://www.caferacer.net/forum/techn...otorcycle.html As apprentices we used to charge up higher voltage capacitors with a 'megger' insulation tester and chuck them to someone.

I keep meaning to find a big hill and keep practicing until I get it, just have not got round to doing that yet and was intrigued as to what the device was. I have a couple of times turned the ignition off one click too far and put the parking lights on, come back and there is just not quite enough juice to start it. I have seen those commercial battery pack that can jump start a car/bike but this home made one looked like a bit of fun to make!

Re: What is this and how do I make one...
Some people can run alongside the bike then jump on sidesaddle and bump start it, but being an uncoordinated tool I'm pretty sure it'd be all bump and no start if I tried it. I had an old piece of junk at uni, bumped it God knows how many times, mainly by being pushed and using 3rd gear.

Re: What is this and how do I make one...
You are treating a symptom and not a cause.
If you are using up batteries there's something wrong with the charging system.The workshop manual has checks for the Stator and the Regulator/Rectifier. In a previous post I pointed to these Power Boost Jump Starters, https://www.amazon.co.uk/DBPOWER-800...r+jump+starter I have a pal who has one and they work.

Re: What is this and how do I make one...
The curvy SV reg/rec is known to be rubbish. It is old tech and gets no cooling, a recipe for disaster.
I replaced mine with a MOSFET unit, far better without doubt. The SV is a very hard bike to bump start, only attempt with someone else pushing, even then you will struggle. |

Re: What is this and how do I make one...
I doubt you could bump start if the battery is completely flat. It happened to me and there wasn't enough juice to get the fuel pump to prime. No fuel, no start.

Curvy doesn't have a pump?
