Handle bar throttle sticking problem, any help appreciated

[Freedom X]

I have a 1981 p200e vespa and the throttle get stuck and isnt smooth.
I road the scooter and almost killed myself because I couldnt get it
out of thottle, I opened the head and took out the handlbar. and
cleaned out the handle bar, greased it up and put it back together,
still no luck. Anyhelp? Has anyone else had this problem?

I once had the throttle stick wide open on a bike when I was doing
70mph and just heading off the main road to roundabout. One advantage
of a bike is you can pull in the clutch, switch off the engine and
coast to a stop.

This was in winter. Water had got inside the cable sleave and froze
locking the cable in place.

I don't know the bike in question, but I would check the cables next
myself.

Well, in truth I would take it into a shop for them to check...

If it only occurs AFTER you have opened the throttle right up and want to
throttle down, AND you are sure it isn't the cable, it MUST be the
carburettor.
Slacken off the two carb mounting bolts a couple of MM and see if this fixes
it.
Don't slacken them too much or you'll get a fuel leak from the base.
This is caused either:
by 'warpage' of the carb body (don't laugh- I've thrown one away before as
it was too badly twisted!-put the carb on a piece of glass and see if the
underside is flat or remove the throttle slide and look at the opening and
see if it's 'square')
Or by a bent throttle connecting rod (the bit the cable attaches to and
moves the slide out).
I had this on my T5 a few years ago, and what normally happened was that the
cable slipped out of the rod when throttling back, but the revs kept going!

Could be a sticking cable, in which case you need to oil/replace it. Or it
could be in the carb. take it apart where the cable goes in, and clean/oil it,
stick it back toghter and hey presto.

Experience reckons that it's most likely to be a sticky cable. Don't bother
oiling or greasing replace the whole thing.

For the benefit of all, the Mick Martin MkI Cable puller instructions are.

Go to a motor bike garage/scooter and buy a 7ft length of cable inner and a
solderless nipple. Attach the solderless nipple about 3 inches in on one end
of the length of cable and do it up really tight. This is now a "cable
puller".

Detach both ends of the cable to be replaced, remove the inner but DO NOT
PULL THE OUTER OUT. Put the new outer onto the cable puller and slide right
up to the nipple. Insert the cable puller into the old outer and when it
comes out take up the slack so that both outers are end to end on the cable
puller. Wrap the extra around your hand and smoothly pull the old outer
through and notice how you magically leave the new outer in it's place.
Carefully remove the cable puller from the new outer and insert and connect
your new inner cable.

Replacing a throttle cable should take around half an hour first time and
cost around £15 including the cost of your cable puller. Don't throw it away
as it also works for clutch and gear cables it even makes front brake
easier.

Mike,
would a good nylon line work do you think (say fishing line)
instead of the long inner cable? I've just tried BeedSpeed for instance
and they only do standard cable lengths.
Cheers,
Ian.

Two solutions.
One - use thin fencing wire and a vicegrip as a big nipple.
Two- yacht chandlers make up cable loops with swaged ends for
sailors. I plan on getting them to put me a swage on hte end of a
length 12 feet of 2mm stainless braided cable.
Three - nylon line like fishing line would be too flexible to push
thru, but strimmer line would work, probably

[Ian McKiver]

For the record, the answer is that although fishing line (or the line
they use for strimmers) will both fit OK and not snap, if the old outer
is knackered enough the nylon line will chop :-(

The garage pick the bike up on Monday. Stop laughing :-)
Cheers,
Ian.

CORRECTION

15ft of cable inner, today for the first time ever I measured one of my
pullers and it is 15ft long not 7ft as I stupidly wrote before.

SORRY,
Mike
