Coil upgrade

I do them with new connectors £55 posted if you're in the uk.

Thanks Andy, I live in France. What I was wondering was which are the best pencil coils to use.

Cbr929/954/1000rr

Thanks very much, I'll look for some here!

Yes, bought four for fifty €, fitted and they do make the bike seem smoother and more responsive, need more nice weather to kep up my scientific analysis regimen of back road "point & squirt" technology!

Hi,

Do all these have similar connectors? Is it possible to mix e.g. 929 coils and 1000rr wiring harness with connectors?

Yes

Thanks!

I've recently experienced 2 coil failures. https://cb500.forumotion.com/t6347-idling-problem-with-video-link

Apparently this has not happened to others who have done this upgrade?

Anyway I'm wondering if the coil gets too hot inside the cyl head when the upper part is plugged??


How is the upper part in original CBR installation? Is it plugged to prevent water and muck but also cooling air flow entering the bore??

Not to disregard Melitos' above query, I do not know the answer to the above and I also have a question re this upgrade.
Does anyone have a dummies' guide for this upgrade?
Could a novice such as I undertake this mod at home?
I'm wondering whether having a set of Cb500 coils to work on / upgrade would be preferable to trying to do it in situ on the bike itself, i.e.

there is no technique but to follow the steps indicated here, knowing that one is not one of those who destroy everything they touch ........ that there is.
it has a greater degree of difficulty removing the original coils

Hi ANDYC do you still sell the stick coils? I would like to buy some from you.

This is exactly the same problem I've had with mine (fireblade coils)but then I striped the carbs thinking there was some blockage in the jets. I've now wrecked them trying to move the pilot air screws so I'm after a new set of carbs.
I did try a different set of coils but then again I may have put the original ones back in by mistake as I was rushing.

I suggest the fixation that I indicate embracing the cylinder head cover tunnels from the outside, which fixes them more without vibrating

Mine were well fixed in there with some bits of rubber drive belt at the top to stop them jiggling about. The coils were off a cbr954rr I think. I'll try the other pair when I've sorted the carbs.

I wasn't looking forward to having to do a carb strip, so I thought of going back to the standard coil. When I did this, the bike started right up immediately and has run smoothely ever since.

Hmmm.... Interesting.

I have a set of @ANDYC 's coils waiting to be installed. I'll be reading this thread.

I've used them for 60k+ miles with no issues, on race bikes aswell as road bikes.
