Could anyone help me out with a few pros' and cons' between a V3 Mugello and a Casa small block kit? I'm just chasing the word on the street. I'm after a bit of an all-rounder I guess, 'round town and country roads. GP150,BGM 60/110 HPC crank,TM24,varitronic,Sito Ancillotti,std gearing
cheers

casa kit is a mildly tuned ali barrel where as the muggy has a much higher state of tune with a bridge inlet and boost port. i would take a guese that with the set up you suggest the casa kit should be 10 - 12 bhp where as someone clamed today that the 186 has given them 19bhp.
my view is that 16+ bhp is what is needed for a safe long distance scooter. although im not 100% happy with the 225 i would opt for the 186 in you situation

I'm leaning toward the Muggy, as it is a little cheaper and seems to be more popular, but Cambridge Lambretta tell me that there is no kit to suit my crank

Frank, does the RB20 match your crank? Not exactly a tourer, but might be the only option..

No the RB20 uses a 58 x 116 crank as std.
I think that there's a 192cc version of the new muggy, uses a 60 x 107 crank as std, but surely the 60 x 110 can be used with a 3mm packer?

I'm hoping that that's the case, cause' right now i'm feeling like I been duped in buying a crank which has no real use.

I,d go along that route, or keep the 60mm and change the rod.

I read this elswhere today
"MB were testing their RT190 this week, which produced 18.2hp with 14lbs torque. On a 58mm crank, no matching work to the casings and no tuning! But amasingly with a 24mm Mikuni and a standard tail pipe Clubman! And 50cc tuning reads 10% higher than the MB dyno aparently."
its strange how these smaller kits are giving the bigger kits a run for their money
The rt is specificaly designed as a touring kit, and be supplied for use with any combination of crank and rod.

I would like an RT kit, but it comes down to cost. I guess you can't have your cake and eat it...
But I have faith in the 3mm packer option, just waiting for a reply from Cam Lam...

the picture i posted is of the mugello for the 60mm stroke. mugello 192. its pretty normal to use a packer plate, mbd supply them with their cranks.
its a shame the mugello didnt follow the rt route with a recessed head. mbd are focussed on long term reliability and fuel effiuciancy with their kit, two important practical factors when touring and as my main break down was an air leak from the head then I like this feature.
if you do go for the mugello then make sure its supplied "finished" with a matching inlet manifold and tidy ports. i was bloody annoyed when i got my muggy 225 and it looked like the lot had just come from the foundry so ask them before you order as an additional dellay and £150 bill to finish it off the kit is a p155 take.
do insist that it needs to be supplied ready to bolt on with all finishing done and a manifold matched to the barrel. if they want to charge fair enough but they need to advise of this before you find yourself with a bunch of none matching parts.
the word "fettling" = poor quality and not finished. in my game we call "fettling "finishing" which has a double meaning.
