closed engine case porting? yes. Sticky tape helps. Its easy doable, just use sticky tape to cover the crank case opening. VMC 177

Hi FMP! I'm thinking pnp the super G 177 cylinder in a 2009 LML 150 with 35000k plus reinforced clutch + 2 more teeth and 24 carburetor but without milling the crankcase. For your experience will it be viable doing like this? Regarding the crankshaft and bearings, will they withstand the increase in displacement? Any reply will be much appreciated. Cheers

vmc 10 molle clutch. it will work, but crank will fail some day, u should replace the crankshaft

@@FreakMoPed8 thanks. Another question if you please: is mandatory milling the LML to fit properly the VMC gasket as you showed in video? Or the cylinder can be fit without milling? Pros and cons? Thanks in advance.

both is possible. ported flowed u have better performance

Hallo, finde deine Videos super, habe eine Frage zur originalen Piaggio Kurbelwelle, hält diese einem 177ccm Tuningzylindr wie VMC oder Polini stand? Gibt es grosse Nachteile zu einer Rennkurbelwelle wie z.b. von Mazuchelli? Mir ist klar, das die Einlasszeiten moderater sind, mir geht es mehr darum, ob die originale Welle der Mehrbelastung standhält.

absolut tut sie das. aind sehr gute wellen. wesentlich besser ala manch schwarz verpackte eigenmarke für teures geld.

Both left and right transfer ports on my Pinasco Vespone RX 190 cylinder are too big for my cases and I cannot get a seal. Especially the flywheel side at the rear where it goes thin. I have tried with gaskets and sealant but with no luck. I have been told I need to weld and re machine the case where the cylinder sits so the casings can ammomodate the large ports on the cylinder. Any other ideas as I don't want to get them welded. There must be a way to seal it. Thanks.

u need to weld. yes.

@@FreakMoPed8 I have used jb weld for now. Seems to have set perfect. See how long it lasts. I made a paper gasket. Leak down test passed.

What about the LML "5-port" engine cases which had larger engine case ports than the standard 3-port cases?!?

@FreakMoPed8 4 жыл бұрын

Optical wide ports are not the point, timings are. See the bad perfoamce of the 251cc pinasco t5 engine 😉 wrong timings.

Is it okay to have a mismatched left and right crankcase transfer port?

@FreakMoPed8 4 жыл бұрын

It would be even ok to not open it at all = have partly closed cyl ports

I did the same thing for my first 177 engine (Polini). But after some years, looking back at it, I wouldn't suggest to do that. First: that small part of engine cases being ported won't do much. Second: having an original crankshaft, therefore original intake timings, and most likely an original si20 carburettor, means the mixture coming in will still be not that much. Considering the pro's (little little little performance gain) and the con's (risk of getting aluminum powder in the engine or everywhere else), I won't do that again.

Its absolutely no problem, otherwise i woulsnt show it. , just use enough sticky tape. the old old discussion, if milling is worth it or not. The NO sayers wave with dyno power curves. thats not accurate for flow optimization Evaluation. Only flow measurements are appropiate BUT they dont exist. as long this proof is missing, at least both sides are right 😉 easy fakeable 2d analog paper curves are not valid. Just raise the tyre pressure foe instance. But i am planing something with a technical school so far, we only have experience and also for instance my silly onroad acceleration tests. 😂😉 Soon coming, just cylinder optimized, nothing else. Before and after. gonna be interesting, isnt it 😃 Trust me, every flow optimising shows effect. every. Only piston optimization ia feelable and ahows effect. And so does removing these edges.

@@FreakMoPed8 I'm not saying you gain nothing by porting it like this. And I'm also not saying that it's a scandal to port the cases with engine closed 😁 But I'm saying that for the small performance gain that you might get, it's not worth taking the risk of powder into the engine.

@FreakMoPed8 4 жыл бұрын

there is no powder in the engine ;) sticky tape helps, gently air cleaning & then flushin with its cleaner than before when opened with all that gearbox oil sucking
