It depends on what kind of bars you're putting on. If you're fitting clip ons, the OEM master cylinder is not great at all. It doesn't really allow the correct angle of the lever for comfortable position.

 You can find a detached reservoir master cylinder on ebay with the correct piston size. If i were you, I'd just look for a master cylinder off a compatible GXSR, that way you know the piston ratios will match up.

Also that snap ring was a pain in the ass. I think I broke it in half to get it out, since the rebuild kits usually come with them .

Yeah, I'm not 100% sure what I'm going to do yet. I just found this one and it seems reasonable and period correct http://4into1.com/replica-kawasaki-complete-brake-master-cylinder-use-on-honda-too-14mm/

Haven't done the math yet but this chart seems handy: http://www.vintagebrake.com/mastercylinder.htm

I think you just need to concentrate all efforts towards getting the engine back in her.  and hear her run before spending too much effort or money.

For sure, I'm not going to buy brake stuff until I need it but it doesn't hurt to fight with that snap ring while the carbs soak.


Kits come with secondary main jets but not primary main jets.
Primaries are pretty specific to the CB360 carb only.
Stock 68 works best for just about every application but 60~65 should give better performance and economy on transition around 4,500rpm

hm... these are what I didn't get and what I needed because my kits didn't include them: http://www.common-motor.com/honda-cb-360-Secondary-Main-Jet-68

It's been a while, but I think the OD on the wheel bearing is 52mm, which means you just need to get 25mm x 52mm bearings and some wheel spacers.

Thats easy enough to find out - did you not have to machine out the inside of the hub to fit the larger axle and more importantly the even larger spacer? That's the only part I was worried about but if all I had to do was swap out the bearings and spacers that'd be great!   :D

Here's the clean carb with the new stuff in it, you can see the jet that's all chewed up from the vice grips I used to get it out...


I'm not sure if that's primary or secondary but that is the one I didn't get and ordered based on the picture haha.

Also, I'm not sure if an O-ring goes in here but it seemed to fit nicely so I left it.


And one more picture just because.


The kits did come with new needle jets but the one in the carb didn't seem to be damaged or easy to get out so I just left it in.

The GSXR rotor came in too so I can make sure everything lines up correctly when I'm fitting the front wheel. Definitely will be an improvement over stock.


Looks like it will fit nicely.


Just a rough line up but there seems to be plenty of space between the much wider GSXR caliper and the wheel when it's centered between the forks.


And it looks pretty sweet. Might need to figure out something with the extra caliper bracket though...

Liking this build...maybe mount a dummy disc/caliper or cut n polish the old mounts off?

Don't get me wrong....but if you're worried about how to modify the front spindle how will you cope with a mono-shock conversion? There's more to it than just a few brackets welded on to the frame by all accounts. Check out threads on here where folk are attempting it....interesting information from those what know better.

Carry on chap.... ;D

Did the kits include the pre-formed bowl gasket I see on the right hand side of this pic?  Or is that the old stock gasket?

Be sure to re-use the original stock springs on the A/F mix adjusters.  Originals are formed flat and smooth on the ends unlike the cut wire springs that come w most kits.  The sharp ends can shave brass/aluminum clogging the pilot circuit or A/F circuit.



The carbs came out super clean   8)  The chewed up jets are the Main primaries.  The "needle jets" are the Main secondaries.


 
These main primaries (same but longer) can be modified to replace them.  Like PJ said (stock is 68) you "may" eventually want to go smaller, but you wont know til you get her running.  I might have 55s in mine...But my carbs are HEAVILY MODIFIED.  Installing smaller Main primaries could make it too lean and have over heating problems, but most likley stalling on decel.

Speaking of which, I finally found some for a reasonable price on ebay (from 4-into-1). Had the hardest time sourcing these and they must have recently become available.

I've already done a couple of GSXR front ends onto 360 (even though one ended up going to Australia for Neevo on his CB400f)


This is before steering stem was modified but with stock wheel assembled and CBR600 rotors/calipers (with adapters)

I used a Suzuki Katana front axle and made spacers for it to fit into the oversized holes in fork bottoms. The spacers allow wheel to be properly centered (slid to side in pic to show how it was done)

I'm just sticking with stock size jets for now - and just making sure I have all the ones new regardless of the name haha.

I found this on google,

Which seems to match the naming consensus, does that mean I ordered the wrong jets or are they possibly labeled wrong on the site? They looked like the ones I needed and didn't come in the kit...

This is the kit I bought: http://4into1.com/shaped-o-ring-float-bowl-gasket-set-of-2-honda-cb360-cj360t-cl360/

The thing I referred to as the needle jet is the thing in the middle without any threads - it looks like you can push out the old you and press that one in but I don't think it's needed in this case.

It did come with the preformed gaskets - that's a good point about the springs though, I'll have to double check and see if the ones that were in there are still the originals.

Thanks bro, just ordered a pair.  You can still get them through Honda but they come w all the other o-rings as a set...$16 per carb.  ouch.

They sell them off the website too for half the price (plus shipping)... probably a wash if that's all you needed but something to keep in mind if you're ordering several things: http://4into1.com/shaped-o-ring-float-bowl-gasket-set-of-2-honda-cb360-cj360t-cl360/
