CB360 - working on it on the weekends

You don't need a rear brake, you do need a front brake

Truth, my Aprilia agrees with you

You don't need a rear brake, you do need a front brake

Eh I didn't have a helmet with me anyways, I do want a working rear brake though just to feel better about it and I use it when coming up to lights, downhill curves, whatever. It's not like the front disk is the best either.

This is bit late, but what about stainless steel bicycle spokes? Your local bike shop should have at least 2mm, 1.8mm and 1.5mm in stock.

Didn't think about that, probably would have worked too but would've been more work/more expensive than grabbing a hanger from next door and cutting it. Seems to work so far anyways

I have a good idea of how I want the rearsets to mount and where it would be comfortable/be usable with the shifter/brake lever. Just need to draw something up with cardboard and take it to the machine shop and see what he can do. Also planning on rerouting brake light to the front lever, which would clear up where the bracket is going to go

 

[edukaycheon]

So instead of using the CBR rearsets I'm trying something different, using the GSXR rearsets straight into the passenger peg brackets after pushing the exhausts as far down as they could go. Brake side has the CBR return spring, and it's pretty comfortable, I don't really hover over the rear brake but it's there if I need it.

Might not look like it in the picture but there is a pretty good amount of room for the lever to move, have to find some joints and connect it up tomorrow.

Shifter side is a bit trickier, just took the peg and some bushings and bolted it onto the same passenger pet bracket, but since the shifter I have isn't part of the peg I have to get creative. I'm thinking about making something to bolt/weld in near the old footpeg mount for the shifter to spin on, hopefully linkage will have the right amount of throw after shortened, etc.

Also messed around with the clipons, brought them above the triple triangle instead of below which makes them look weird, but handles a little nicer and puts less strain on my arms/back. Will wait to see how they feel after actual riding instead of just sitting on it and making engine sounds while leaning from knee to knee and twisting the throttle

You must be young and bendable. when my legs are at that kind of angle my toes are pointing almost straight down. something would snap if I tried to bend my feet up like that. lol, but its really not funny anymore. simply a hospital visit.

 

[edukaycheon]

6'0" and not very bendable...I may take up yoga to continue riding ;D I can ride the pegs in the middle of my foot and move my feet quick enough if I need to shift or brake though. I have to be careful with my clip on positioning and how far the reach is because I already have some issues with my back

 

[mattfeet]

I thought the same thing...My rearset levers are pointed down 30*, or close to it, (if line parallel with ground is your basis of measure, my levers are down at a 30* angle).

 

[crazypj]

Haven't measured angle but it's probably around 20~25 degrees

I was 5' 11" but back injury shortened me to 5' 10"

 

[edukaycheon]

I agree it's not ideal but my exhausts don't let me bend them any farther down, otherwise they wouldn't be able to shift up/push down enough for braking. I'm going to see if I can bend the exhausts any further down and get some more room today

 

[edukaycheon]

So yeah I pushed my exhausts all the way down to the limit of the current bracket, there's more room for my feet than before but I don't want to push anymore, exhausts have a bend in them and I'd be straining them otherwise. Right now I can get the middle of my feet on the pegs and get on the brake comfortably enough. Going to weld a peg for the shifter onto the bike near the engine support rod, took measurements today and took them to the machine shop, he should have the peg and custom linkage rod done in a few days. I was also thinking about connecting the rear brake with linkage that goes backwards directly to the brake instead of to the existing assembly like most people do

 

[edukaycheon]

Haven't been working on the bike as much as I'd like, but still getting some stuff done.

Since my brake rod was bent/broken from me being an idiot before, I decided to hook it up to the rearset backwards, ignoring the stock assembly thing. It doesn't have much actuation in the lever, but I think I've got it to where it doesn't drag and I can still stop the rear tire by stepping down on the lever.

Looks kind of sketchy, but it works. The angle of the lever is in such a way that I can't ride covering the pedal for long distances, but I can still move my foot on top of it quick enough to step down.

Shifter mount peg is machined, just need to take a few more measurements and mock it up with the linkage for the shifter, then I have to pull the tank and carbs and all that for the bike to go on it's side for a while and have the peg welded on.

Also I got the opportunity to ride this Thruxton

that was sitting around the shop yesterday, it was kind of fun and a huge improvement in power and braking, but positioning was not comfortable and I still like my bike way more. So much lighter and nimble, and it just feels better. I probably don't have to tell you guys, but I'm betting I'd be faster on my bike in the canyons than I would be on that bike.

 

[mydlyfkryzis]

From an engineering point of view, that brake rod is terrible. You lose a lock of braking control because of the flexibility of the rod.

You should be riding with the balls of your feet on the pegs anyway... not your heels.

 

[edukaycheon]

The rod really is terrible, the bend in it kills a lot of the pulling power but right now I just want to have something for short rides once I can get the shifter on. I'll do it up properly eventually. Yeah I don't really know how to describe it but my feet are comfortable on the pegs ha

 

[edukaycheon]

Here's what the shifter looks like right now:

I have to tweak the linkage a little and adjust the angles so clicking is more precise, but otherwise it works! Shift lever clears exhaust, can comfortably get over/under to shift. That metal peg coming out from next to the engine mount bolt needs to be trimmed a little then I need to pull the carbs and tank off to weld it on. I realize a lot of the stuff on my bike doesn't look very pretty or all that functionally sound, but I'm having fun figuring stuff out. If it breaks, I'll learn from my mistakes and fix it. But as always, I love hearing advice from the more knowledgeable folks here

 

[crazypj]

It's good to see how other people deal with specific problems.
It doesn't have to look pretty to work, I've seen way too many 'pretty' bikes that were far more dangerous after being chromed, 'slammed' 'customised' etc

 

[trek97]

Now thats pretty darn neat.

 

[Sonreir]

GP shift?

 

[edukaycheon]

Nope, normal shift pattern. The upward V in the linkage lets it shift normally, but I'm going to play around with a few different angles and see which one works the smoothest. Not a fan of GP shifting though

 

[realsugeknight]

way more vinyl then I need today for when the seat's cured, probably be able to work on it next weekend :-\

Where did you pick up that vinyl? That looks like it'd make a DIY brat seat super easy to upholster

 

[edukaycheon]

I got the vinyl from an upholstery store, the smallest amount they sell is a square yard or something. I had originally wanted to do a brat style seat, had a pan cut out and everything but decided to stick with the cafe seat
