Honda-SOHC

will this work per chance ?

been asked and dont have the kickstart infront of me to measure it.

cheers chaps

sure they dont but have to check as i was asked  ?

answers please

as the 650 gear seems to be next to non existent and i have the patience of a small child full of adhd and too much sugar i shall be going the electronic route.

now if i run a Z1000 clock will i have any issues ?

or i might go hightech and get a vapour clock.

any recomendations ?

cheers peeps

anybody used Barnett or ebc clutch springs ? not bothered about day to day usage just want something a bit more substantial.

i have read putting 6mm washers pre loads the springs for better action but thought i might go heavier duty than that.

thoughts ?

Anyone around this way ?

just took the 550k3 cafe out for a quick pre MOT shake down, the CRs make it pull like a horse but i forgot how totally bullshit the front break is on these old girls, may have to do the twin disk conversion.

cannot wait for the next sunny day for a proper thrash!

good vibes all around

 

So gents all help and points welcomed. settle back and i shall tell you the info:

engine: cb550k3 standard with a very mild porting job on the head, more just smoothing than porting, no polishing tho!

carbs: Keihin CR 29mm
Pod Filters
mains: 240
main jets: 120
mixture: 1 1/2 turns out
Needles: right at top position
timing: checked and rechecked (!)
floats: Factory set 14mm
ignition: boyer bransden, with mini coils

So have tried various settings but taken her back to 'out the box' carb settings.

To start her she must be on full choke and i can only get her to 1/3 choke before she dies. i cannot get idle no matter what i do.

when she is on full choke she revs right up with no trouble. when the choke is set at 1/3 when you pull the throttle the engine loses rpm/power. i know she is running lean and i have tried 118 and 122 main jets but i cannot get any kind of idle.

carbs have been bench synced and i have tried different mixtures etc but all the same or worse probs and no idle.

have tried advancing the timing on the stator plate but to now avail.

Need a bit of direction here peeps. how much bigger should i go with the main jets? am i clearly missing something? 

(beer tokens for the best answers!)

so got my CR29s fitted all sweet and just dialing them in.

due to the throttle cable length difference from the standard carbs i have switched the return cable to act as the pull on the throttle.

i makes for less turn on the actual throttle but the carbs reach their lock positions.

does anyone foresee any problems with this ? have had it running and it seems o.k, but should the throttle have more travel available for the carbs ?

yes you know its that cb550 k3 lean burn carb time!

so she will start but only on full choke, if i reduce to 2/3rds choke she will die. no idle.

so my thoughts are to richen first ? running far too lean or does this sound more like an air leak ? carbs were fully rebuilt with new needles and floats.

floats were set as per book -
running k & N filters.

want to to carb sync but i am right in thinking this will be irrelevant until i can get a solid idle?

all help as always warmly appreciated.

so close but yet so far
