Moraysan,

Just a consideration; even if you find hardware that fits, the gear ratio of the drive unit may not produce the results that the instrument is expecting to see. In other words, the speedometer may indicate more or less MPH than you are going.  Wheel/tire size can be a factor there, also. 

Speeedhut is one good option, but there are many good options to pick from, for your new GPS speedometer.

I put 2008 gsxr1000 front-ends on three of my fjs. I used a digital speedo that uses a magnet and sensor. I replaced one of the rotor bolts with a hex bolt. Drilled the top of the bolt. And epoxied a magnet into it. Mounted sensor to the  caliper bracket. Ran the wire along the brake line. Works great. Cheap.
I don't know how to post pictures on this new forum.

You can find that 6th gear by simply switching to 18 tooth front sprocket and 38 tooth rear sprocket......no more hunting for 6th gear  :good2:

Thanks Dean - you provided the solid answer on why use the FZR1000 yokes.

The width is correct for YZF600 wheel and brakes, and the offset and stem are both correct for the FJ1100/1200

Thanks for all the replies. I like the Speed Hut gauges but to replace the gauges would cost more than half of what I just paid for the bike! 🤪
Below are some pictures of the forks/wheel to see if someone can help with the model of Yamaha they came off. This would be useful information anyway.

Quote from: Pat Conlon on June 30, 2024, 10:44:01 AMInteresting Joe, a couple of Q's...
Are the Brembo's a 4 pot or 6 pot caliper?
 How expensive are the pads vs. the common Yamaha monoblock pads?
 What size piston on the master cylinder is used with the Brembo calipers?
(Yamaha monoblocks work best with a 14mm)
What about radial vs axial master cylinders, both work with the Italian calipers?

Got any pictures?

Cheers.  Pat
The P4 (65mm) caliper is four pot with four seperate pads, they came standard on the Ducati 999, unsure what mastercylinder size was used and as for replacement pads, I've not looked into it.
The 40mm mount Brembo's have been used on almost all other Ducati's prior to them going to radial calipers.




As for master cylinders, I'm not concerned about feel, what ever this is supposed to mean, I just want maximum stopping power when I grab a hand full of brake.
I have a pair of RCS clutch and brake cylinders, 17 and 19 which I'll pair with the 40mm P4 30/34 and the P4's from the 999 with an adjustable master cylinder from a Panagale.

Up until recently I had the Panagale cylinders on my ZRX (stock 6 piston calipers) and after adjusting I got eyeball popping power with one finger, I have it set a bit on off but it certainly stops

I did the 40mm Brembo caliper mod on my 1990 VFR750. OMG.... the increase in stopping power over the 1 sided, 2 piston Nissin calipers is amazing. I also purchased and installed the matching Brembo master cylinder.

Quote from: manden on July 10, 2024, 12:24:29 AMDo they add any rigidity?

Where are u located?

They are bolted at 2 different points on the frame. I would imagine that a small amount of rigidity is added.

Never heard of Seafoam. Will look into it. I always fill up the tank with Mobil Premium. They advertise it contains Techron fuel system cleaner. I always try drive it at least once a week to keep the fuel moving. When I had the gum up issue I had not driven it for months.
