1983 Honda 750 Nighthawk

3M 80 is the stuff to use. Big box stores carry it. Follow directions and it will be great!

I found the 77 worked fine - what’s the difference between that an the 80? Strength I’m guessing, but for me the 77 worked great with foam.

I use 90 lol....never had a separation.

77 is a little bit lighter-duty, 80 is rubber/vinyl specific, 90 best for laminates. They will all work probably, I just prefer the specific rubber/vinyl design of 80.
 
The blurb on the can said 77 is recommended for foams. Moral of the last page or so of this thread - stick with 3M. Oh wait, that's catchy.
 
How are those two yoga mats for comfort?? Have you ridden it like that?

I'm still undecided on the seat foam as well.

I see you've made good progress....I've not ridden on the seat pad....but I've got a smooth pan under it and in trial 'sits' its felt ok. I didn't want a thicker seat and would consider using a removable gel pad for longer times in the saddle. It's the look I was after with some comfort.
 
This is what I picked up today...very very pleased :)

Had to throw it on....the stainless trims need securing as does the padded centre piece, but the contrast is awesome, even if I do say so myself.
 
That looks great and very grippy! Nice work there.

What make are those controls? They look awesome as well. Got a link to those?
Thank you...it's lush.

The rightside start/run/kill switch is a Honda Dominator part.. that's what the fella who sold it me said. Neat n tidy. The left side is an ebay item, and while not the finest quality works well enough.
 
Every custom bike I build gets the SV calipers, including those with GSXR and TL1000r front ends. Most of the time, they require nothing more than $2 of flat stock with 4 holes drilled. In most cases, I weld threaded bungs to the brackets but you could just as easily use flanged nuts. It takes far less effort and money than what you are doing here. I've been watching this thread thinking you are taking your approach to avoid the extra bracket, for a cleaner look or something.

Hey IRK, how is that SV caliper held on to the bracket? For the SV both sliding pins are on the caliper itself, but i don't see any any nut on the back of the top bolt. Side facing out is not accessible. Side facing in has no nut. What am i missing here?

That bracket itself is threaded. My adapter plates are drilled with two holes and the screws thread into the bracket through the adapter place. I drill two more holes in the adapter bracket for the fork mounts and use two weld nuts on the adapter bracket to thread the fork screws.

Ok thanks! So on the SV both of the sliders are on the caliper. I was looking at some 80s honda ones here and they have one slider on the caliper one on the bracket. Kind of a silly setup.
 
I am considering IRKs approach with the SV calipers and adapter if the GSXR calipers are a fail, but I'm also looking at how much I can shave off the calipers here for a sleek fork-caliper OEM combo.

Turns out the caliper is actually thicker than I thought. I measured it with a dial indicator, several times, each time getting between 4.3 and 4.6 mm. Just in case anyone is curious what these 4 pot gsxr ones are for thickness

Using the vernier caliper - that's a lot of meat before you break through. Shaving 2mm is really not going to be an issue here I dont think.

I'm happy now.

I cant wait to ditch the center stand.... but I still need the thing

Turning radius is going to SUCK. I dont have the skills to do tank dimples that would give the forks clearance, so extended steering stops will have to be the way.

I have shaved calipers for fit on several occasions, and one thing I am watching for is heat transfer. In my case, i currently have an AWD Chevy Astro van which has a 1/2 ton rear end and brakes made for 16" rims. I wanted 15" rims for better offroad tire options, so I shaved a mm or two off the top. So far so good, but something to watch. I imagine boiling brake fluid is going to make your brake really, really soft or non-existent.
