Some more for gents. Sorry. Lol.
Front disc, I've found out it's 4mm thick what about overall diameter and the PCD?
The kill switch, I get what it's for but how does it actually work, wouldn't turning the ignition off have the same effect?
Once again thanks.
-
The kill switch interrupts the 12V feed to the coils, Turning the key off does that as well, in fact it turns everything off.
-
Also for the fact that if involved in an accident, and the bike falls on it's left side, you cannot get to the ignition to turn it off, so the kill switch gives a quick way for someone to kill the engine and help prevent fire or blowing the engine if it starts to rev, also, if the throttle jammed open while riding it :o, far easier/safer to reach the kill switch than the ignition switch :D

And burning your hand on the exhausts trying to switch the ignition off ;D

I thought you were going to use the Honda switchgear anyway. Being too minimalist isn't a good idea.

Thanks gents. Mike, not sure yet. Weighing up pros and cons to be honest. Ordered and received lots of parts, just waiting for more and then full on into it. Having trouble finding a petrol tank that fits/looks good on the bike. As some of you know it's a bobber hardtail with a radiused top yube. Nothing fits right, they can be made to fit but they don't look right then. Hunting and surfing the big wide world web for something that fits and looks good. Any info on the disc gents would be greatly appreciated as well. Thanks.
-
Gents, any info on the front disc sizes. I'm surfing the net and getting different answers of it. There's nothing about sizes in the Haynes manual I can find. Thanks.
-
750 and 500 discs have the same centresd, I seem to remember the minimum thickness being on the alloy centre and without going to measur one the 750 is a bigger diameter than the 500
-
What do you need to know about front disk? I can pop out to the shed with a tape measure if required. I am pretty sure the cb500 and cb550 disk are the same, but 400 and, 650 and ones 750 are not.
-
The disc is 6mm in thickness and 11" diameter. It looks to be the correct size, not sure about the thickness though. The caliber won't go any where near it when I try to put it over the disc. Thanks.
-
Do you mean that the disc won't fit between the pads or that the caliper mount holds the caliper too far away from the axle
-
The disc won't fit between the pads.
-
That's because you've got the wrong calipers. The older bikes had thicker discs than these new 'uns
-
I was going to say wrong calipers or seized piston
-
The disc won't fit between the pads.
If the piston is the right one and is all the way back, some repro pads are too thick. Recall another member having this problem but, can't find the post.

Mike, I've got a proper caliper now, eBay find. It's a proper cb500 one. What is the correct disc thickness for the disc? Thanks.
-
It should be in the manual
-
Doesn't t give a thickness or diameter. Looked on the tinternet and various different answer to be found.
-
I seem to remember 7mm but I don't know from what, so...
-
7mm sounds about right, cb500 and 550 had comparatively massivly thick disks. Is the piston right back in the caliper? Have you got the right pads and mount? I often help the pad back into the caliper body by squashing it back into the caliper with a G clamp, protecting the caliper from dammage with a few bits of wood.

I'll try it tonight when I get home. Nice one thanks.

Forgot to say, scrub it with a toothbrush if there is any rust or crud visable.
