Part# for a 66.2 mm piston ring?

Hey,
I don't have a local scooters shop and would prefer not to have to wait for shipping for 2 weeks. Is there a part number from a manufacturer like wiseco I can order at a motorcycle shop for 66.2mm piston rings?

Anyone make a PX Grimeca MC work on a lambretta?

I've got a S3 with the onboard disk. I want to convert to semi-hydrolic. I know there are a few set ups based on the piaggio typhoon MC. I've got a brand new one meant for the bolt on disk brake for the vespa PX sitting on the shelf. Just wondering if anyone has tried it, say fitting like the oiltec...

Gori 200 - thin cylinder walls?

Hi, rebuilding a tv175 s3 but do not have the original jug. I dont want to build a road warrior as I already have one of those. Was going to put on the Gori 175 kit, but it looks like the 200 kit has more or less replaced that. If it uses standard case studs, how have they managed to keep the cylind...

Backfire past 3/4 throttle

Hey, A GP200, 22mm jetex, 125 main, scootrs pipe. Plug chops after a long ride is okay, light tea, could be a bit darker but I did not think alarming. At 3/4 throttle it back fires.

Re: Welding old style crownwheel with springs?

Would be interested as I have the same. However I would be inclined to leave it as is if all looks good. Yes it will fail in the future but until then .......

Welding old style crownwheel with springs?

Hi, I have a few of the early s3 crownwheel that are 2 pieces with springs, with zero wear on them. Before binning them, I'm wondering if anyone has tried welding them and how it worked out.
