The circled part is the anchor point for the return spring. You don't normally need to use it as the old one can be re-used. I suppose they include it in the kit in case you have to fit a new cover as well.

I did peen over the lever edge, but only enough to keep the parts together. I think a small amount of side play helps to keep the cable pull straight.

Cheers

If you mean the repair kits, as far as I know they are ok providing your side cover worm threads are not too worn. If you mean the pattern side covers, I have one of those and it's ok as well, but they are now expensive for the pedal fizzy, when available. This thread was really about repairing a side cover with a worn out worm thread that would otherwise be scrapped. If you have a later non-pedalled fizzy the mod probably wouldn't be worth the effort as genuine and pattern covers are still available at a reasonable price.

If anyone else has had a go at this repair I'd like to hear about the results.

I ordered a replacement worm drive set a couple of years ago from 50cc.nl and received the smaller unit. I had obviously ordered an incorrect original replacement, but not knowing what it was originally designed for I quickly decided it was ideal as the worm drive in my casing was pretty worn out and this one came with a replacement female 'plug'.
I reamed out the old worm drive as the replacement was exactly the same size as the hole in the casing less the worm thread. I cut out a key in the side of the casting for the plastic lug to fit neatly into so as to avoid it twisting with the operation of the worm. This needed some working as it needed to be relaxed in the right position with plenty of throw to engage the clutch when operated. It took about an hour to install and it worked a treat. It even looked as though it should have been there in the first place.
I take my hat off to mech73 who has done a lot of leg work on the engineering side to make this an impressive after market type retrofit and will undoubtedly save a lot of good original side casings from being scrapped as they are no longer available. Good work...
By the way one of you guys has the bike it is fitted to as I later sold it on ebay. If my memory serves me correctly it was a gold SS (NUD xxL), but can't be absolutely sure.

I'm currently having problems with my worm and spring assy, the pattern Fs1e parts aren't really cutting it. The upgrade looks like a good idea, but where did you get a hold of the genuine RD50 parts? I can't find genuine worm and spring parts for either Fs1e or RD50??
Help?
