@@FreakMoPed8 Hi mista, i have a polini 221 and just ordered a grand sport piston. Is there anything to gain? I have 1,5mm spacer on top. Is it better to have spacer at the bottom? Thanks
Hi Mr Freak, I measured the engine diagrams (221) that I will mount, here: 173/118/ 28, intake: 82/191, is it consistent? the setup: Malossi V one engine case, Malossi 210 cylinder, Mazzuchelli (K2d) crankshaft long stroke (60), head gasket 2 mm, SI carb 26, exhaust Pipedesing Sbox III plus. Thanks. Tschüss
Hi MFP. Watching this from the UK. Hope you are well. Do you think,or have you heard if Malossi may introduce a 244 kit...or maybe you could advise them if its possible. The 210 sport seems to be the best available PnP kit but could be brought further up to date. Regards and stay safe👍
thx. even better info: vmc isn working on a 221cc. already testing protos. its gonna be better than sport. no need for a 244 malossi. there is quattrini 244 and the eve. better vmc244 which is aprilia knowhow 😉
Even for a new 210 malossi from 2023 you would do 2.0 instead of 1.5 at the head? I used 1.5 in my new built 2 weeks ago and I am in fear now. Btw your videos are great. Greetings from Bavaria.
You are the man! What's the best 60mm crankshaft for the 221 sport with rotary valve? I don't want to cut or weld the crank to adjust the timings/balancing! Tuning the intake valve is ok I guess.. Cheers!
not worth the money. A bit more cc is completelly overrated, its other factors. Better go for m244 then instead of extra longstroke. there is only sport or m244, dont see any need for mhr.
Mr Freak, I’m building my 79 p200 engine per your recommendations in this video (malossi 221). I will take the time to fine tune. I rebuilt my Cush drive with DRT springs, but still have the stock helical gears. Do you recommend going to strait cut gears with a 221 sport? Or is it overkill? Thanks for the best Vespa tunning tips!
Hello, to see if you can advise. I am mounting the Malossi Sport 210cc Kit (2022) CODE: 3118591, with the malossi CARBURETTOR KIT PHBH 30 BD REED CRANKCASE FOR VESPA PX E 2T 200 CC CODE: 1615550 and Polini Box exhaust. What model of crankshaft do you recommend for this configuration? Many Thanks
Hi Mr Freak, Good job! A px 200 Malossi 221 engine is planned and I need a crankshaft… a Mazzuchelli long stroke has a long timing (138° or 140° ) it is not too much for use with carburettor SI 24 or 26? Tschüss
@@FreakMoPed8 0.05 is for intake. Precisely I also wanted to ask you for the Malossi casings, have known other people who had problems of tolerance greater than 0.1 mm. Are these casings a good choice? or are the Pinasco casings better? Danke

It would be interesting to have more details on how to make the exhaust port larger... (same shape, top and bottom equal) do you just widen the sides or do you also check if the piston at the BDC is at the same level ? I heard that someone lowers the port under that level of ca. 1 mm more... do not understand why....
Hey dude, sorry for bothering again but I the more I am watching your videos, the more questions are coming into my mind... It's great thing isn't it :P --- 1) from my measurements, with 60mm stroke, the piston at the BDC sits 1mm lower than the exhaust port! Could this be a problem? should lower the port? 2) with these changes in timings, do you recommend a different gear ratio? Malossi manual suggests a 24/63 for the 210 in 57 stroke (px200 original is 23/65) but... do you think shorter is better?
Hello mr freak. Great videos as always. Thx for share. Man, i have a Question for You, which values do You use in GSF Dyno? Cd Value, Friction Coef and frontal area? Thx in advance
to my knowledge when you take the PORTMAP with the paper, you actually measuring the length of the ARC. However the 63% has to be referred to the CHORD of that arc. If you are going to make it 43,5mm - it is ca. 59% (chord is 40,6mm); for having the 63% you have to enlarge the port to ca. 47mm (chord would be 43,5mm then) [see Gordon Jennings - Tuning Handbook]
@@FreakMoPed8 👍🏽 so just for the records the original malossi (at least mine) port is 55% [arc = 40mm] to have the 65% [arc = 48,5mm] you have to go more than the MHR that has 64% [arc = 48mm], enlarging 4,25mm per side. 🤯
Thanks for the video Mr Freak! So basically If I want to upgrade my Malossi SPORT from 57 (210) to 60 (221), I have just to put the 60 crankshaft and a 2 mm base under the head? I've not understood why 2 mm and not 60-57=3mm ... Moreover, don't you think that 1,5 + 1,5 (top and bottom of cylinder) would be better for maintaining the port position as designed by malossi? big thanks!
It depends on the cylinder. A 221 only works with 60mm stroke. A 210 with 57 or 60. In general, a 60mm stroke is NOT needed. 57 & 60mm with same engine data, have the same power on road. Just different power band. People just think, the more cc the better, but there are many kore factors defining the power of a two stroke engine
Hi Mr Freak, I measured the engine diagrams (221) that I will mount, here: 173/118/ 28, intake: 82/191, is it consistent? the setup: Malossi V one engine case, Malossi 210 cylinder, Mazzuchelli (K2d) crankshaft long stroke (60), head gasket 2 mm, SI carb 26, exhaust Pipedesing Sbox III plus.

Good job!! Malossi recommends a 0.8mm squish, why did you leave more squish? Thank you!!
1.4mm I recommend
so for longstroke head gasket a 2mm instead of just 1.5mm
@@FreakMoPed8 What diameter gasket did you mount in the crankcase?
standard for 210cc

yes, exactly. on rotary go for 63 and just widen it till top edge transfers channels, in a trapezoid or butterfly shape
For fast touring trip, do you prefer Malossi in long stroke or in standard c57 stroke? For Long stroke 221, what gear ratio do you suggest?
it really doesnt matter. if original 57 is fine, stick to it. no need for longstroke, its quite overrated. I like 65/23 for these tunings

das sie exakt passen, das geht schon. ständerbohrmaschine halt.
hi.. how about the transfer port layout/flow shape of both of the cylinder? do they have the same shape or they have totally a different layout?
Yes
Longstroke head from mmw or mrp is not a better solution?
not really needed no. but you can of course, so you dont need a head gasket
