LTH Europa 225 kit.

Thanks guys!
I am asking about this kit because i have a RB20 in a Lambretta and i want something less "racing"
I want something with more fuel economy (because the Lambretta have std fuel tank), if i can, mantain the air box, maybe mantain the original clutch or to put only stronger springs, ... you know.... GOOD AND CHEAP ....... hahaha.
Now i have a 200 engine with new bearings and seals fitted, MecEur 58x107 crank, JL3 Curly and electronic ignition with lightened 2Kg flywheel.
I hate the running in , previous i have a Mugello 186 and now a RB20 and i love this type of kit running in.
Is the TS1 the kit that i need? what carb?
Thanks!!!!!!

What do you think about to quit 1mm or 1,5mm on the base of the TS1 to do more tourer the kit?
With a standard TS1 kit there are more modifications to do in the Lambretta? offset frame cones, shorter rear shocker, hole in the panel (for example with a 28-30 PHBH), ...
The std manifold is good enough?
Thanks again!

If you know a good engine builder who can put together a standard TS1, then it should tick all the boxes. They can be very reliable, returning decent fuel economy, but the initial cost is more than a Rapido or similar, and a TS1 will test most standard clutches.

The 130degree transfers sound a little excessive. I spoke about transfers with JB last week and he finds that 130 produces engines that need a lot of revs.

I have been having trouble with the 190 engine in the Abarth, so I spent last weekend taking 1mm off the bottom of the barrel, inserting 1mm of clearance in the head, all in the name of lowering my trannies from 130 to 125degrees. I am hoping that this will cure the problem, which was that the engine was not able to pull 4th gear, whatever the sprockets. It was also a git to carburate.

Perhaps it was my configuration, and I haven't ridden the bike since the re-build, but I will err towards mid 120's for future transfer timings.

Similarish to mine.. I'm running a Rapido 225, Mec crank. I've a tino clutch, and running with a B-Race stealth. Carb is either a PHBH or a PWK (I change, got the PHBH pretty well dialed in. But a slightly rich PWK does run better, just that jets are a pain to get over here.

Pretty torquey motor, I'm pleased with it.

If you get a Rapido, make sure you get the piston clearances checked.. I learnt the hard way.

I am the unique engine builder that i know near to me
For this reason I ask this things, because I must do everything and i dont know about to tune cylinders, but if i can do a better kit with simple things and your experience, better .

Let me know how do you feel the engine with this modification please.

What Rapido and carb do you have?
What about the running in?

Thanks guys.

Rapido 225cc. Carbs are either PHBH 30mm or PWK 28mm (Genuine round mouth, not the OK 30-28 oval).

I only use Silkoline at 4%.

Running in.. took it easy for about 500ks, was running like a dream, then heat seized two up at about 100kmph on the motorway and it was about 35 degrees! . Inspection showed the clearances were way too tight. Barrel was matched to the new piston, seems right as rain now, had a pretty hard run, two up for about 150k's p the motorway and it didn't miss a beat. Drank fuel though, the motivation for a LTH reed kit.
