Hi Dude!Excellent tutorial, great job man! What are the main differences between Polini 210 and Malossi? Which is the best for you? Thanks ad cheers!

polini has the weak asso piston, which is known for cracking as a connection pin eye to skirt is missing on one side. Beside that, its still the technical 80ies port layout (...) so easy answer: malossi sport Not only cause of non cracking piston, also new 2014 design. Checkout my other guides about it

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!

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....

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.

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?

@FreakMoPed8

2 жыл бұрын

1) no 2) 65/23 is fun max 65/24 if fine tuned and a lot of power

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!

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!

not really needed no. but you can of course, so you dont need a head gasket

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]

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
