the saga continues...

[SkidMark]

well now having the PV working again (turned out to be the servo unit - now have a spare cdi and reg/rect ), the bike will not idle.
I start it on the choke but after it warms up I turn the choke off and it dies. I think I messed with the idle adjustment sometime in the past so now don't have a clue even roughly where it should be and it is really hard to set when you have to keep reving the bike to stop it dieing. I guess this could be the result of it not being run for a while although the fuel was drained from the carb. I had the hunting thing before so have a pilot jet to put on - could this be the problem or could it just be getting the idle set right. If idle adjustment is the prob then where to I start? I would gues that all the way clockwise would be high rpm?

Any hints, help, clues, advice appreciated....

On the A/R its a left hand thread on the idle screw yea go figure, but that's the case, i also think having this set correctly also has an affect on the servos , as a clue if its set to high, you tend to get pulsing affect on tick over , take the obscure black plastic cover off and you will be able to suss out the workings and give it all a good WDing ,i would guess you have the screw out to far ie no tick over at all.
Good luck

Nice one mate

try this... back out the tick over screw so it is not touching the throttle stop plate anymore.
then turn it in so it just touches it.

then turn it in 1 to 1 and a half more turns.

once you get her running fine tune the air mixture screw.
start at the setting reccomended in the manual and then slowly turn it in in small increments until the bikes begins
to run worse or begins to stall. then back it out slowly until the revs pick up and you hear what sounds like it's
at the best point. back it out a little more - if it gets worse again you know you had it at the best spot so screw
it back in again to that point.

then fine tune the tick over.

If you have to turn the mixture screw out by more than roughly 2 and a half turns? you will need a richer jet
if you have it screwed out less than a full turn you will want a leaner jet.

I forgot to add when you are setting the air screw set the tick over so it is running the slowest it can before
it stalls, this way you will hear and notice the effect of adjusting the air screw more.

oh and I mixed up the jet thing i.e richer and leaner.

so just swap round what i said about that - if the screw is less than a turn out it will want a richer jet ( not leaner)
etc

cheers guys will try tonight - wife and kids permitting

also give the jets (pilot in particular) a good blow through as this will also stop it idling off choke. Jon

have popped the cover off and the vacuum system seems to be working ie blipping the throttle makes it move but I just had another thought - I converted the single throttle cable setup to the original dual setup. If I dont have the cables adjusted correctly then I guess this might cause this problem? Never had a dual cable setup before so I just adjust the 'pulling' cable so there was some free play and checked that it went stop to stop and then set the other cable after. What is the proper way of setting up the dual cable system?

[fallenmikethebike]

remembering its a left hand thread , wind the tickover out till you get the pulsing tickover , then slowly wind it back in till you achieve a steady constant tickover, that also allows the throttle to be cracked open without stalling the engine , fine tune on mixture screw, its probably worth popping a new br8es basic plug in for this exercise.Sorry i cant comment on your conversion to a single cable set up , and on the face of it your findings sound secure , but i guess big H put that other cable on for some reason???
good luck

where are the cables going to at them moment? From hazy memory... the throttle cable that splits into two -
one side (can't remember off hand which) should be on the right side of the carb pully and the other to the oil pump. Then the other cable that leaves the throttle body at the handle bars should go to the left side of the carb pully.
