its not about the condition, its about the power. checkout my facebook boxexhaust album. the siproad 1 and 2 is very old and only provides low power. it kindof throttles the engine with a good modern cylinder.
Hi Mista FMP. First, I’ve got to say, what a great channel. Your knowledge is first class and your videos are excellent. I particularly like that you are more interested in things functioning correctly than looking pretty 😉. I am getting back into Vespa tuning after 30+ years and it has made me realise I didn’t really know anything then, and what I did know I've forgotten. I have a PX150E which I’m using for fun and I have picked up a nearly complete 1983 P125 engine to spice it up (I'd like happy all day 100-110kph with ability to overtake at 120kph+) It is missing the ignition, piston, some smaller components and needs a new crank. I have it completely stripped down, ready for full porting and rebuild. Shopping list- -VMC 177 stelvio kit -24mm SI carb -SIP fixed ignition -fast flow fuel tap I have some questions which I hope you can help with- -Could you recommend a 57mm crank? -Which off the shelf clutch would go well with this? -My 150 already has a SIP Road 2 exhaust, should I consider something else (not too loud though) -Are there any other main parts I have missed, or parts you would change? I want to put a single order in to SIP and hope that everything I need arrives right first time so I can get on with it.. (not a chance!!) Thanks Nick
thx! 😁 sharing is caring. A lot changed. No one would habe expected that! Primary 65 Sip ultrastrong clutch 23 would rather take sip road 3 the v2 is quite old already mazzucchelli is a fine crank If u need a new one go for 60mm and add a head gasket
@@FreakMoPed8 Thank you for the quick reply- it is really appreciated. I don't know where you find the time. Unfortunately SIP road 3 not back in stock until Feb 2022. You suggest in your comments below a Polini- would it be the racing exhaust (SIP code 2002018)?. Also on your videos it seems a 60mm crank needs extra opening work on the VMC 177 Stelvio cylinder ports. Would it be better to buy VMC Crono 187 instead for 60mm? I'm happy doing case porting, but eyes not what they were for fine work in the cylinder ports..! Thank you again, Nick
poliniBOX / polini original box is the one, one or the best box exhaust. polini racing is sca, ever since. pure optic & sound tuning but nothing else than an original exhaust looking different. if are capeable of porting cases, you can also port cylinders, wait, gonna show you: ua-cam.com/video/pIcKh45Erv4/v-deo.html also 57mm is fine, longstroke is by far overrated, intake and cylinder timings are more important. ensure rotary valve tolerance 0,05mm and take care regarding oil sucker weak spot
thats why the polini racing is scam. its the perfect throttle but far away from being a racing exhaust. sadly still sold with old & wrong 90ies info / promises ua-cam.com/video/lKZ2LwHmHP8/v-deo.html

I wish you would do a video on how to tune the carb with a starter motor in place. I know you mod it be able to use a flathead, but I've heard others say that it didn't work for them. I can't see how a flathead would fit myself.
Ciao complimenti per il video , volevo un consiglio , sto montando nel mio px 150 questo vmc stelvio 177 alluminio , e mi domandavo se nei bulloni di fissaggio testa e cilindro ci vanno delle rondelle ? Poi la testata a una smussatura , questa smussatura dove va sopra o sotto ? Poi la limatura dove ce scritto vmc se e troppo limata che conseguenze puo avere ? Grazie aspetto vostra risposta
Nice Vid FMP! Do you have an idea what would be the difference if you abstain from the milling work ("real" PNP with VMC 177) if you do not want to change the casing for any reason?
similiar result, works fine. i just can not assemble parts that dont fit nicely, where there are edges, ie putting a 24mm carb on a 20mm casing hole, thats nothing my nervs can take :D ;)
with my Vespa Sprint Veloce, I added a Scooter centre reed plate as the rotary pad was dead. (this raised the carb box 12mm. I had the engine case opened up at the manifold just like a red valve engine. Like you I added a 177 kit and a 24SI carb, but I haven't drilled the 1.5mm hole which feeds the main jet. Is this why it starts fine but even go 100mm and the engine just stops???
@@FreakMoPed8 to strengthen the clutch, did you weld a metal band around it to stop the clutch basket expanding and the clip from coming out (happened to me once)
welding is no plug and play tuning ;) no worries, in my 20y of vespa experience, good sealing mass never got loose. it even keeps sticking to the small spot in the gearbox at the kickstarter sprocket, sprayed with oil all the time (the closing trick)
Hi mista, what's the jetting used with that setup? I'm breaking-in the SuperG kit at the moment. My setup is a mazzi 60mm stroke Crank, 24-24E 2.3mm drilled Passage, BGM Fast Flow tab, case is fully ported. Malossi Pipe Exhaust. Trying jetting right, i was using 55/160 and the plug is Black. Totally Black. I change to 45/140 and start to see Dark Chocolate color in plug. My Main stack is AC140-BE3-MJ120 and bogs a little in partial WOT at 3rd

Thanks. Ill order some jets and experiment. Unfortunatley parts orders are taking a long time to get to New Zealand post Covid. 1~2 weeks has become 3 months.....
OK so a bit of an update. I have fitted a 125 main jet (dellorto sizing) and it runs much better I was incorrect about it having a BE3 fitted it always had a BE4 The VMC was fitted because I had a wrist pin failure on the Malossi 166 that was previously fitted. It was running a 130 main jet but on an undrilled carb. It seems to me that drilling the carb passage drive the main jet down considerably??? I could possibly even go down in jetting a little from where I am at present. (122 or 120)
the "big" mj were not big, they were just not fed 100% due to too little fuel. now the jets are fed 100% = are what the stamp on it says so yes, the jetting may go down with the big ones it may drown now

Very good kit the vmc I have it with long stroke and the sip box exhaust
Which sip road
@@FreakMoPed8 sip road 2.0
get a newer one, its aprox 10y old and throttles the engine. try polinibox or newer sr3, u will be very surprised!

@@FreakMoPed8 Yes please!
Nice video..
the carburetor is tightened with 16-19 nm!
sry 16-18 nm
Its tightened that the slide dont clamp. no torque key needed
What jet settings did you go for with this setup? As always very informative video cheers
mj 125, ij 2,7 with airfilter & 2 holes
rest standard
Do you need to change the oil pump's gearing in order to up the oil ratio?
No
why didn't you clean the housing?
sure i did, what do you mean.
Nice video. How long is the break-in period?
set everything right, few km for engine warm up, then full throttle for 5km & done.

English pls
Hi FMP. It don't need to extended intake timing rigth?
Also works pnp yes. For more. Power intake timing is needed
Do you recomend to change the clutch with this engine ?
of course. its a must.

yes it is! sorry didnt see this comment till now...

2,5mm it shall be pls. maybe it sizes yes, but "engine stops" is a general statement, it can have many reasons. In any case, you need a 2,5mm bore
when strengthening the clutch do you use a 20mm / 3mm piece of steel flat plate or is it smaller than 3mm thick???
sorry, i didnt get what you mean...
@@FreakMoPed8 to strengthen the clutch, did you weld a metal band around it to stop the clutch basket expanding and the clip from coming out (happened to me once)
For those 6 crank case nuts, what spec did you torque them to?
max, before threads die.
bolts 15, screws are harder and can take a bit more
how do you seal with no gasket face on casing bro top left corner ? lots of sealant will just fail ?
sealing mass works perfect. it will stay in place.
@@FreakMoPed8 mmm I would have welded and built up gasket face in my 40 years of experience it never pays to cut corners . Nice vids bro
