Mk1 Suzuki Bandit 1200 — Tacho Not Working!

Comfort.
I think I've been cramped up on sports bikes too long, because I absolutely love the comfort of the GSF1200! Just this Sunday, after a bacon and egg roll and flat white at Cafe Metz, I headed up the Goat Track. For those not in the know, it's a cracking little road full of hairpin bends that takes you up to North Tamborine. Great fun, up or down, whatever bike. 
Fifty K's per hour is how fast I was going. Fifty K's! 
I was more mellow than a bong-induced mellow guy from Mellowford, and happy to cruise. Until six or seven bikes flew past me like I was on a pushbike!
I took chase, but gave up when the front got a bit iffy in one of the bends. All good, back to Sunday morning cruising.

So what's this thing like day-to-day?
Honestly, it's blown me away. It's quick when you want it, happy to mooch around at snail's pace, just a cracking allrounder. I'm fixing up little things as I go, and making a list of things I want to do.

One thing that was niggling me since getting this thing running was the rev-counter... it wasn't counting the revs. I had two secondhand CDI units, it didn't work on either. I had continuity from the tacho (black/red), back to the CDI. I had 12v and a good earth at the tacho itself. So the tacho must be faulty? One would assume so. But to assume... 

New Old Stock.
Secondhand rev-counters were going for around $150 on eBay, if you could find them. But then a NOS one came up for $300. 

Suzuki Bandit 1200 — Brake Caliper Stripdown.

Nissin Calipers Overhaul.
The Bandit has been a lot of fun so far, but one thing was niggling me. Although all the discs and pads looked quite new, the rear brake was squealing so loudly I was actively trying to avoid using it.

So a couple of weeks ago I thought I'd whip off the rear caliper, clean up the pistons and pads, and apply some grease to the backs of the pads. During the cleaning of the pistons, I noticed part of an O-ring sticking out on one side. The only thing I could do was unbolt the two sides of the caliper and remove the pistons to see what was going on.

The secondary O-ring (dust seal) must have been so dry at some point that it got caught on the piston and worked its way out. However it happened, I popped out the pistons, cleaned everything up in soapy water, blew it all dry and refitted the O-ring along with rubber grease. With careful refitting of the piston, all was well. Obviously this was done with both sides of the caliper, and then new brake fluid was flushed through. The back brake was then perfect... and silent.

What I did notice while the caliper was apart was the amount of orange, jellied brake fluid hiding within. There is no way this stuff is getting out unless you strip the caliper completely, which left me wondering about the fronts...
