CB500/550 / Re: twin disc conversion
« on: September 02, 2013, 07:19:13 PM »
ok,update coming,

forks arrived,they must have been for a 550k,so the slider was the same length as my 500.,
think the internals are different,but I am expecting to just fit on my existing stanchion,and use same springs and internals,

disc ordered,

and caliper,bracket hoses,etc

I intend to use a double length banjo to join the brake pipes,so I don't need to worry  about brakelight switch,

hopefully the new bolts,and speedo drive mods will go OK

you are working hard Ewan,

 I suggest you get it on the road,run it for a while,get used to the feel.bed the tyres and brakes in ,
then explore the handling,

I guess you have some great bike roads around you,

go and have some fun

In that case you will need the slider from a 550 or a PAIR of forks from a 550 (internals vary so fitting just one complete fork is not advisable) plus if you look at the other thread on twin discs I linked a word document with a How To.

Thanks Bryanj,  I downloaded your instructions,and am sourcing parts,are 550 fork tubes the same Diameter as the 500,and will they
fit my original yokes?can I just swap the 550 sliders onto my forklegs and internals?
thanks for your help,

all of you

back to feebay to explore more ;D

hi all,

as you can see from my profile pic,I have a well used 500,

for the past 6-8yrs I have used Avon Roadrider 90/90 x 19 f,and 100/90 x 18 rear,

as both need changing,
I am going for the new Dunlop Streetsmart 3.25 x 19 F,and 4.00 x18 R,

both sets run at 29psi F,and 36 psi R,

the Avons make the bike feel light and nimble,like a little 250,gives me confidence to touch the footrest and stand,hopefully the
new Dunlops will be as good,and even better,my rear is lasting up to 3k miles,the front about 8k, :) :)

what tyres do you prefer??

this is aimed mainly at the owners that ride the bike,rather than just polish and  show them,

all comments welcome

John

I know this is headed CB750 exhausts,

 but the 500/550  Hm 323 are short supply,DS has none,CMSnl has sets,very expensive,

I asked a guy at DS,he said they were looking to get sets made,but no information yet,

mine are 20yrs old,and getting scruffy,can expect then to corrode soon

CMsnl 500 sets are 1808 euros,on their conversion,£1,555  VAT included

must get my piggy bank filled

Tricks & Tips / Re: Front Brake Adjustment
« on: August 12, 2013, 06:09:41 PM »
 hi ,

 I have CB500-4

 I had problems of the brake rubbing to much,pads not retracting,

I cured it by replacing the piston seal,nice fresh and flexible,it pulls the piston back
a treet,
also,if you remove the spring from the adjuster,and let the caliper move as it needs,it
inproves the braking,

the seal cost about £3.50 ish
