Re: Re:

It would be wonderfully convenient if the OEM bellows could cope with larger carburettors, let alone more efficient carburettors requiring a greater volume of air. Truth is, no such luck! The 26 mm carburettor you have needs 40% more air even if it is only of the same efficiency as an SH22. If the ...

Re: Re:

So today I tried putting on an "Atomic" elbow designed for a remote filter, but with no filter. Normally starts first kick once warm, with the elbow on it was very difficult to start. Elbow is off again and still wiping the petrol off the floorboards after every ride [emoji2] Sent from my SM-G985F ...

Re: Checking Torque Settings

However, the fundamental cure for head leakage is to eliminate the weak link. I have not used head gaskets since the early 70's & will not do so again. Interesting. Is that with standard Lambretta cylinders and heads, or "special" ones? Any engine that I build inevitably has the head modified to su...

Re:

It must be something that I do with an engine that doesn't enable piston ported to run with a standard bellows or, as I have tried, an elbow of below 40 mm. Mind you, engines that I have fettled will run extremely well with suitable air filters, it's just that the size needs to be adequate. In fact,...

Re: Checking Torque Settings

I know this will get an whole load of flake but I don't re-torque mine anymore. When I started I never had a torque wrench that went down that low so I never used one. When I came back into scootering I read how important it was so I checked a few but they never moved so I have abandoned the idea. ...

Re: Modify Gori GP50

If you've had seizures then something was wrong. If you've not fixed it, then obviously you can expect further trouble. So far, the current set-up (apart from exhaust) has seized twice. If it's not due to the exhaust backing up, air leaks, carburation or ignition, then it really is due a strip down....

Re: Modify Gori GP50

As a scooterists since 1973, my generation had very few 'clubman' exhausts available (Royspeed & Ancillotti predominantly) so made our own. One thing we learnt the hard way was about heat build up from the exhaust bleed...... I have had occasion to work on other people's Lambrettas fitted with the M...

Re: Modify Gori GP50

If you can cut & weld, almost anything can be made to fit. Will an RB be any better? Not if it's not set up properly, like the Rapido you have which must be set up badly to be so gutless. A home made clubman (smaller bore 'U' pipe, 25 mm bleed to silencer, long reverse cone, side cut for ground clea...
