Hello there!
Thanks for taking the time to read this thread and your input will be much appreciated!
I was riding yesterday and the throttle was snapping back fine. I pulled over for a bit and when i re-mounted my scooter the throttle kept sticking open - this made for some interested gear changes in the center of town! Also it was very hot yesterday.
I took the handle bar cover off and disconnected the cable from the twist grip. The actual twist grip handle was quite stiff in the hole so i removed it and cleaned off all the old grease on the handle and in the hole. What grease would you recommend to put in here? I just used some 2-stroke oil as a temporary thing.
The return spring (is that what it's called?!) on the handle seems a bit weak to me as well, could this be the problem/ part of it?
Also I tried pulling the cable by hand when it was disconnected and it felt a bit stiff so I stuck some 2 stroke oil down the cable (Ok, ok I know this isn't the correct juice but it was all I had!)
After doing these things the handle doesn't stick as much and does snap shut sometimes.... buttttt unfortunately it does still stick open too much for my liking!
Are there any common faults in this area, anything I may have missed, or one of the above that I should tinker with more?
thanks - Ali

First up, the spring inside the handlebars is normally weak, I'd not worry about that, the carb spring does most of the pulling.
As for the rest, normal copper grease will do to lubricate the throttle tube, low melt grease will do if you have none - as long as it's lubricated, then you should be fine.
It sounds like you've allowed the throttle cable to dry out, a little surface rust has developed, and that's binding on the outer. 2 - stroke oil is perfect for lubricating it, so don't worry about that.
I'd do it a couple more times over the next few days and see if it improves any. If not, then it may be that the cable has started to fray, it's not a big job to change it, but generally you don't get any improvement from that once it starts to go, oil won't fix a broken cable.

Its also worth checking its not the carb slide.
Follow your throttle cable to your carb. Check the slide by pulling the 'hook'/rod where the cable attaches too.
This should have a bit of resistance and snap back pretty quickly.
If thats all ok then see above ^^^^

Thanks for your help sbwnik, I've got some copper grease so I'll clean the oil off and replace it with some of that.
As for the cable I'll try lubing for a few more days and if I get no improvement looks like it's a new cable. Have you got a good technique for lubing the cable? I was using a funnel and just trying to aim as best as possible!Sslightly messy but I think I got some oil in there!
Thanks vespasco I'll check out the carb slide. Is there anything you can do to improve this, grease the mechanism etc.?
Cheers again.

I don't want to sound alarmist, but a fraying throttle cable is best attended to pretty sharpish, I'd say.
I just has similar with a clutch cable. I was fighting it as it was getting stiffer, not realising that the frayed cable inside the outer was actually scrunching up inside until it jammed fully - so much so that it was a real struggle to pull out, and I ended up replacing inner and outer.
A pain in the bum for a clutch, but I wouldn't be happy with the prospect of my throttle cable jamming up like my clutch cable did.
Just a thought, certainly worth checking carb end too, but if you suspect a frayedcable, i'd say change it sharpish.

too lube it old skool ,plasticine funnel an a overnight drip feed til it runs out carb end ,or a bit of rubber pipe split lengthwise pop on an seal with gaffer/parcel tape an another overnighter, modern way ,good aim with a wd40 can with little pipe in nozzle ,it goes every where ,or a cable oiler,little clamp that goes on cable end an directs lube down cable from can , H

I use a length of pipeover the end of the complete cable, then fill it (it's about 2" long) with oil from an old fashioned lever oil can.
About an hour or so to run down, job done. I do it when working on other things on the scooter..

Just replaced my throttle cable on same year and model, I tried lubeing the original cable but no joy, taped the new complete cable to the old one and pushed/pulled through the frame, the cable snagged on the plastic tray inside the frame, so had to remove the fuel tank to feed it through.The hole in the tray is about the thickness of a pencil. complete throttle cable from beedspeed £2.75 nice an smooth now.

The cable is feeling better so I'm gonna keep lubing and hope for the best!
Checked out the carb slide and ooo what a motion, snaps back like a beaut.

Cheers for the how-to-lube advice too, I found a funnel I use to top my car up with oil. Just before I stuck it on I said to myself ' I can't use this it's covered in oil' ....

always clean ya funnel an top of oil can before use , they gather dust n dirt whilst sitting around in garage ,an ya dont want to pour that into anything you like to work. same with my pre-mix jugs ,i always stuff em with garage paper towels so they aint gatherin dirt between uses . H

That twist grip seems to have been very dry, you can see what looks like a rust contact patch on the inside of the switch housing.

eagle eyed nic, must have better glasses than me ,or are cheating with a magnifier glass,havin the throttle tube stiff from no grease wont help ya cable from sticking again, looks like another scoot thats had a low/no maintenance owner in past ,might be a idea to go right round it with a oil can/grease gun/wd40 spray an lube everything that should be lubed .H

ah I think that's just copper grease. not a bad shout to go round and lube stuff up though.
I recently changed my speedo worm gear because it was mashed which has made the speedo work however the speed is wrong, you guys got any tips?
One guy told me a should just accept the speedo doesn't work because something is always broken on a vespa, so if i fix it something serious might go wrong lol

never mind something ,if the speedo works i always suspect it either a lml/baja badge clone or sumting major is about to die, vesp speedo's just dont work or record faithfully ,tryin to get em too is a "exercise in futility" ,serious zen/buddhist/magickery ,might improve your "soul" but your patience/wallet wont improve .if it was a earlyer type ya could of mixed up 8"/10" drives but px's only have 1 ratio drive ,if speedo is now seriously under reading check ya cable n oil it first ,or replace before thinkin ov changin speedo's ,there not cheap an quality is variable,putting it politely .h

Working Vespa speedo. Bless....  Ten years and counting... Seriously, I'd not worry about it, it'll only die again. |

I've decided to never look at, touch or think about a speedo ever again.

when I rode scooters the 1st time round I used to be really impressed that I was hitting 70 regularly.....15 years on and now a car driver and more aware of how fast i am going , I now realise how pointless they are, although that doesn’t help with the advent of speed cameras and the amount I slow down for possibly unnecessarily

Post by alisey on Aug 26, 2014 21:13:21 GMT
So how fast do you think you were going all those years ago?
I'm the same with cameras, either slow down way too much or follow someone else if there around!

On my T5, i think i was maybe doing 55, possibly 60 at a push on the flat.
With my current speedo i now think 60km's is about 30mph, even though it should be nearer 50km. I aim for no more than 75km in a 40 zone

ahhh mine's the same way round! When I'm going flat out my speedo says I'm doing 40mph
