Re: lambretta adjustable length rear shocker

The better 'rebuildable' rear shock absorbers usually allow for some adjustment in length by virtue of the lock nut beneath the top eye, but you should be cautious on ensuring enough thread engagement. I would say 1.5 x D minimum. So, besides Protech that you already know about, there is Gaz, if you...

Re: Tv175 disc brake squeal

I can’t help I’m afraid, my SX200 squealed with cintered pads. I just put up with it and eventually it stopped on it’s own. I never found a solution. As an aside, I’m not a fan anyway my well set up hub with shoes on my SX150 is a much better brake. "All sintered pads are equal, but some are more e...

Re: Lambretta Electric start

With or without an electric start, something I'm thinking about is a decompression valve. I know that a hole can be drilled in the exhaust port area "that doesn't affect running" but I may be just too stubborn or stupid to adopt that measure. Automatic decompression valves are available that utilise...

Re: Perfected technique to save a crank bearing race

I made this bearing puller for £20 works great and no damage took this original gp race off in seconds https://uploads.tapatalk-cdn.com/20201228/cc572b31a6a004f218a6d0589aee331d.jpg https://uploads.tapatalk-cdn.com/20201228/c7d97b54185f38f8e8abdb2f01c806fd.jpg https://uploads.tapatalk-cdn.com/20201...

Re: Carb fuel problem

After setting the float to the correct height as depicted, courtesy of Garry, & with the carburettor still upside down, you shouldn't be able to blow through a piece of fuel pipe connected to the banjo. Obvious, but worth stating As the carburettor is turned to the correct orientation of normal posi...

Re: RB improvement

I don’t know that the reeds are hitting the piston, I thought I read that the corners are hitting the barrel inlet somewhere . Sorry! My mistake in misreading your Post. I'm not aware of the reeds fowling anywhere. I don’t know that I want to reinvent the wheel looking for a piston, l was hoping th...

Re: RB improvement

If the reed petals are causing an issue by hitting the piston, then packing the manifold from the barrel may be the solution. I am unaware of a more compact reed assembly to suit, but you may find them more easily Stateside. Packing may necessitate eccentric cones. The crown of the piston relative t...

Re: Auto Lube System

There is no commercially available autolube system for retrofit to a Lambretta two stroke as far as I am aware.

The idea is feasible, but so is fuel injection. My guess is that a combination of the two might surface in the near future.

Re: Carb fuel problem

I suggest that you take the carburettor off & examine it thoroughly on the bench.. With the float & needle removed, remove the float needle valve. It should be a '200' or larger.. With some aerosol such as carb/brake/GT85 etc with the tube extension to the aerosol top, blast the orifice where the fl...
