So long as theres free play wherever the bars are, thats OK You say left lock is a little tighter. do you mean its difficult to pull the lever or theres no free play or what?

Right, there should be a little free play at the clutch lever before it begins to pull the cable check it with the bars at left lock, centre, and right lock

so there is absolutely nothing wrong with the throttle cable, it does the job you want it to ? But when you put the bike in gear and let the clutch out, there is a delay before the bike moves forward, which results in the engine revving up too much?

All this time i'm thinking its a throttle, engine revving fault! OK with the bike in neutral can you rev the engine as normal and twist the bars from lock to lock without the revs increasing?

Im getting confused with this now, i thought that it was revving too much Cant you be more precise with whats wrong Revs in a straight line?...dont understand I mean its quite rideable and 1st and 2nd are worse.(2nd is kick ass on these...usually anyway?...dont understand this either Not really revving too much.?...Thought it was Its been a long day, c'mon

What about the other two questions

My god you really do need help Its revving its nuts off now youve rebuilt it? are the new bars wider than the old ones? Does it rev more when you move the bars from lock to lock?

Would i be right in thinking that the cable comes out of the throttle as a single cable, then goes into a tube where it splits into two cables, one for the oil pump and one for the carb slide?

Very unlikely to be too loose What bike is it on?

Thats good news, enjoy your bike.

Sounds like youve either routed the cable incorrectly, or the bars are significantly wider / higher than the ones you replaced. Try to re route the cable so its not so tight!

What ive told you Jim should confirm if the vacuum tap is functioning properly, I know its past your bedtime , good luck tomorrow

What, 68 and riding those, youre my hero

Right Pull off the tube to the carb that feeds petrol to it place a container under this pipe pull off the other pipe, and suck on it this should open up the vacuum valve and fuel should come out of the fuel pipe into the container if it does, replace the fuel pipe back on the carb and suck on the vacuum pipe again this should allow fuel into carb replace vacuum pipe back on carb and hopefully the bike will now run

They might both attach to the carb, but i think one is the fuel supply to the carb, and the other is vacuum to open up the vacuum fuel valve in the tank you havent got a picture of the carb showing these connections have you?

It looks like a vacuum operated valve so its got one pipe to the carb to feed petrol and another to the inlet manifold...yes can you confirm this?

These two pipes, does one of them go to the manifold, and the other to the carburettor?

Does the fuel tap mount directly on the fuel tank, and how many pipes are attached, and where do these pipes go to? Can you explain this vacuum pump to me

Not familiar what is a cw 50 and what year is it?

Does it have a vacuum operated fuel tap?

Its the same on my DT175MX, check without screwing it in.

Hmmm just imagine
