Try this
Use a magic marker
Put a line across the rotor as shown
Spin the wheel by hand
See how it wears
Then again take it for a ride
See how it wears


Yes,  a heat gun would be brill for stuff like this or to check,  how hot the different cylinders get.

The sharpie test is for what exactly?  To see an uneven wear,  if there is any?

Thank you,

Gabriel

I also have a heat gun if you want to compare how
hot certain parts of your  bike gets. Of course, you
would have too have one also.

Project Custom Motobricks / Re: K100 GSXR conversion questions
« Last post by Max on Today at 11:54:34 AM »
Ok, so next problem is.... The cognito trees are wrong for my forks, the trees hold the forks 6mm closer together than the standard 98 GSXR set up. I cannot mount the brake Callipers as they foul on the disks being so much closer together. I'm not sure why this is yet and have contacted cognito, I notice there are a few variations of the GSXR usd forks ranging from 98-2003. I can cure this by filing down 3mm from the calliper mounting points, 1.5mm from each side of the mounting point should not hurt, or find the right forks for the trees, unless cognito has messed up?. Another unexpected problem to solve, so far I am not overly impressed with going the cognito route.

Nice seat for less than what the reupholster job on it cost.  I'd be on that if I didn't already have four seats for three bikes.

If the stock plank is killing your ass get this.

The hinge and pin are not included, I used them on the replacement seat.

Project Classic Motobricks / BMW K75RT Ultima: Footrests
« Last post by Wollyjumperuk on Today at 06:17:00 AM »
I've been looking at the footrest brackets on the bike for a while now and then choosing to do something else. I think it's about time I got on with these.

So, as is traditional, all the components for each side were laid out to see what I had...



... with it being fairly clear the bolts and pins needed replacing, rear footrest holders needed repainting and all the other bits needed a good clean up.

Once the stainless steel replacement parts were ordered, the first job was to clean up the metal centres of each footrest to take it from the condition I found these in to a condition I was happy with, this required cleaning with WD-40, paper towel and a scraper before drying off and application of Autosol Metal Polish with wire wool. Following this a buffing wheel on a drill was used to finish up.

The rear footrest mounting brackets were stripped back with a wire wheel, to remove the rust, before layering up with Autotek Etch Primer, Halfords Gloss Black Enamel, Halfords Clear Enamel Lacquer and being set aside to cure.

With everything cleaned, ordered parts arrived and the paintwork cured off, all the components were brought back together to double check fitment...



... before the old pins, bolts, washers, split pins and nuts were chucked into the recycling.

Starting on the left of the bike, the rear footrest mounts were bolted onto the bracket backplate to allow some minor adjustment ...



... before the rubber was popped over the core, the pin hole had a drill run through it (as it was a fraction tighter on the fit than I'd like)...



... the bearing faces on the mount were greased as was the pin.

The back washer was added to the core, the footrest was pushed into position and the pin slid in...



.. then washered and split pinned to secure it.

The front footrest was easier to fit, although quite fiddly, with the bearing faces and pin greased, footrest added and pinned.

The pin was retracted a little to allow the return spring to be fitted, the seat of which was also greased, the spacer and washer added and the assembly compressed...



... to allow the split pin to be added to secure it all.

From doing the left side first, I found it was a pain (especially with the rear footrest) to attach the rubber to the core before fitting, as you have to compress the rubber to get the pin in - this did cause me to slip and create a little paint touch-up work for me.

So, with the right side, the bare cores (without the rubbers) were fitted to the bike, for both front and rear...



... before the rubbers were added...



... to both footrests.

This turned out to be a much better way to fit the footrests and I'd recommend fitting them this way in the future!
