Modern Vespa

I've finally done what I didn't think I could... 74 vespa 90... Pulled new inner/outter thru (old outter was gone).

I've got it thru the frame - Can anyone walk me thru connecting at the throttle then at the carb?? Pics are where its at for me if you have any. I can see thru the headlight area - the cable is at the back left side - there appears to be a crescent shaped guide of some time that is static just below the moving lever of the throttle cable.

Any close up pic of that area with one attached would be great. Also - a quick pic close up of it attached at the carb and I'll get back at it.

Took about an hour - went thru the horn with about a 6ga welding wire pushed it back and thru - did the duct tape to the new outer and I pulled while daughter gave it some push - came thru very nicely. then up thru the horn with the same heavy wire - when thru did the duct tape - pulled it apart. But - I had it pretty far up - I pulled the headstock bolt and judged the head up about 1/4 inch - from there I saw the duct tape - I used needle nose and pulled the duct tape off and then it slid right up the rest of the way.

First time in 39 years there has been a throttle cable at both ends (dad pulled the outter years ago not knowing how much of a bitch it would be. At the time there was no internet and the manuals didn't give the tips you guys give here ---- kudos and thanks in advance for any help/pics you can share!!

Replace throttle cable.

I'm not sure what type of throttle cable you have.

Some have a lead barrel end on the grip side and is secured on the carb side with either a pinch bolt or you can solder the end yourself. The throttle cable I'm using has a solder nub at end on the carb side and I secure a pinch bolt on the grip side.

Good luck.

You will need to put a "tophat" on the end of the throttle cable (in the headset), and the "tophat" will sit up into the underside of that bracket you see... then the barrel end of the cable will slip into the little cutout in the cable pulley (attached to the throttle tube)

The gear cables on the other side of the headset will need tophats as well.

Thanks on the tophat - on the top end, i slip on the tophat - does the tophat go into the "fixed" what I call guide then the small nipple that was on the cable wrap into the moving throttle mechanism? Hope the terms are enough to follow/verify.

I just haven't seen a pic of exactly what it looks like attached at the top end - the pic i think you sent and the previous like someone added to the thread are of a lambretta I think. Mine seems slightly different.

I won't be able to finish till Thursday due to going out of town - just wanted to have ducks in a row to make it as easy as possible. Still not easy to pull the cable up more into the headlight area - although it must easier than fishing the cable all the way thru.. that sucked but lots of threads out there that made it workable.

thanks again -

Ok, I read vader's post... Think that gave me what I thought - should be able to tackle now.

thanks.. (guess I should read then post....doh).

Not all scoots will require a top hat for all cables. It will depend on the kind of throttle/gear guide plate you have.

On my ET3, the plate is plastic and the cable ends slip directly into the guide. This was noted when I replaced my original cables, the only place I have a top hat beside the choke cable is the front brake cable. I have seen a top hat used on the clutch but I'm not currently using one as seen on the original setup without any problems. I'm going to change my clutch inner out soon and will try a tophat to see if any differences are noted.

Now, if you a metal plate guide, use top hats on the gear and throttle cables and top hats for the clutch and front brake which sit home inside the lever perches.

Throttle/gear guide comparison:

Mine is metal so fophat it is. Assuming the small nipple already on the cable will pass thru the tophat or will I likely have to pull inner and re thread? Thanks.

Ok, one more question... sorry, noob + ...

The cable I have will use a pinch bolt on one end (bare wire..) and it has a small nipple on the other (the nipple is a little smaller looking than some I've seen for sale.. The fixed nipple end - goes to the carb side?

I read to thread the cable from the head side (thinking the soldered end stays there and the pinch bolt on the carb side). Now I saw something that makes me think that's backwards.

Can someone verify which end will get the pinch bolt? Also, anyone have a pic showing the pinchbolt in place on the end that it goes on? IE if it goes on carb side - any pics showing the cable fixed with the pinch bolt in place?...or if it goes on the upper side - any pic of it there?

Sorry to keep asking - once I think I have it figured out it doesn't make sense. As always thanks...

Little nipple goes on the carb side.

This is what you need for the headset end. They are a little trickier than using the fixed top and solder on bottom but a little patience and dexterity and you'll get it. [/img]

Arrrrgh.. I have the cable in backwards.. guess I'll pull the inner and feed up from carb side leaving nipple at carb. I do have the pinch bolt.


Any pics of the pinch bolt on cable at the throttle side? That should be the end of my mystery and then it's game on!!

Thanks for the clarification..

this is a step by step of how to do it on a lambretta which is much easier due to the removable headset top. but it is similar enough that you should be able to get the jist of it.

Thanks for that - I hadn't seen that one - helps. Yes - removable would make it easier. With the outer cable in place, I think all else will be straight forward now. Those pictures make it obvious.

Appreciate the help.
