Re: Motobatt Failure

All batteries will eventually discharge themselves, on or off the bike. If allowed to go too far they will fail completely and need to be replaced. I constantly swap a maintenance charger between bikes to keep them sweet :D

Re: Points or Electronic ignition

The only real benefit of changing to electronic ignition is lack of maintenance needed.

If you decide to change, Dyna S would be my recommendation too. Very straightforward to swap out and will work with standard coils.

Re: KZ900A4 Blowing Fuses

Hello Dave, You are correct, I tried the same switch on another bike and the same thing happens, the 20amp fuse popped . And so it is conclusive, the fault is with the kill switch. Thank you all for your help and suggestions. It was the only logical conclusion Steve. To follow up on Taffus post, I ...

Re: KZ900A4 Blowing Fuses

Z900-A4WiringDiagram.jpg I maybe able to offer some explanation here. Combined reg/rec's only need to be fed with the 3 yellow AC phases from the alternator and be earthed by a single black wire to the back of the engine. Ignore the brown wire going to the orginal regulator. The 3 AC can come from ...

Welcome Dave, I used to live just down the road from you at St Madoes and there is a very keen Kawa man just over the river :D

open the kill switch, check if the inside is undamaged.
Mind there are little balls and springs inside so don't loose those.
Good luck
Philippe


That's the same logical conclusion I came too. I wouldn't look at anything else until the kill switch is checked out.

Looking at the picture, I would say the screw mounting the red/yellow wire is shorting to the switch body. Which, is shorting to earth through the handlebars when the switch is mounted to the bike. This is why it works ok when the switch is removed from the bars.

Re: KZ900A4 Blowing Fuses

Steve, How did you get on investigating the switch?

The fact that everything works when you remove the switch from the handlebars would suggest the switch is shorting to the bars, possibly through the switch housing. If it was the solenoid removing the switch would make no difference.

Re: Carburettor Jets

Interesting that the 1000 mains are much smaller. I guess the other jetting changes compensate? Either that or possibly the Z1000 4-2 exhausts are more restrictive than 4-4 z900?

Personally, I would stick it on a Dyno.

Re: Carburettor Jets

All I know is from 40 years of practical hands on experience which has served me well enough and while theoretical findings are all well and good they don't allow for the variables of each individual engine, their state of tune, type of exhaust fitted etc. With a stock 115 main and the over bore i'...
