Dear all,
Can somebody explain to me where I will notice what adjustments in the carbs.
For example:
Putting the needle Higher, will this result in a better start? or a good "pick up"? or gasresponce? or higher refs ?
My CB500 is at this time not correct adjusted, that I know for sure, but I don't want to go messing around with the wrong parameters.
Currently the CB has a very bad cold start ( needs almost always brake cleaner or starterpilot )and while riding it runs best with the choke "on" a bit.
Though when I pull the throttle full open, the choke ( automatically I guess ) is in "open" stage again, and it runs bad ( lean ? )
NOTE: I have to mention I run open velocity stacks.
I have now recently rebuild the carbs, as they were leaking heavily All needles, jets and rings have been replaced, and the carbs have had an ultrasonic bath.
She already runs a lot better then before the re-build, but I feel they are not there yet.
The needles I have put in the Mid position of the 5 grooves ( I think this is the standard ? ) and I have put the mixture screws 1 3/4 out, as in the Manual.
I feel I should change something still.
Where to start ?
Putting the needles in a higher ( highest ? ) position ?
Or shoul I have the mixture screws less open due to the stacks ?
After that synch the vacuum ?
Does any of the above changes also affect the bad cold start ?
Or could this be ignition timing ?
I have changed the ignition with an electronic one when I re-build the carbs as well, put the timing on "static" will adjusting/ checking this while running change a lot ?
Please can anybody answer ( some of ) my questions ?
