@jakester Out of interest, how is your 24/24e jetted? I use the Pinasco VRX venturi on a BGM Faster Flow 24/24e on my Pinasco 225, but I've never really figured out the carb jetting. Cheers.

Did you change out your gearing to run the bigger wheels jakester?
Also let's see them in a big pic? |

wow, 1mph shy of my 132cc smallframe[/quote]
Yeah pinasco's are for torque not for revs. Can't wait to get the malossi back on. I'm predicting 130-135 with that bad lad. I'm sure your smallie will be screaming it tits off at that speed whereas the pinasco is cruising. That's why people get them as tourers. In my opinion though the pinasco is a pile of shit |

nope, the smallie can (and has) done that speed all day long day after day.
What most people call "Torque" is really a wide power band, and that does not have to be mutually exclusive of power. Torque is power/rpm and since there is a gear box you can change the gearing to get any torque you want at the rear wheel, but you have to have the power and you have to have a wide enough power band to cover the dips between the gears. |

So... Just purchased a 244 Quattrini. Its in the post from Germany. Will be porting it before its fitted. Lets see how it compares to my 225 Malossi

I find surprisingly little on the Internet about the M232/M244 apart from advertisements. Good thing to order it so I didn't have to (yet).
I seem to waste a lot of money in getting where I want but I guess it's quite common. There's a saying: buy expensive and cry once. (Cold coffee and hot women save time is another.) 'Ave a nice dye! |

Wowzers, look at that square exhaust port!! Problem on 200 cylinders is stud location which prevents wide port employment, so you kinda have to reduce top corner radius in order to gain port area. But this is really pushing ring reliability.

Wow what a difference from Malossi to Quattrini 244.
Quattrini has fat torque all the way from 0 revs whereas you needed to wind the malossi up quite a bit before it went. There is a lot more BHP all the way through the rev range also. Quattrini is definately producing more power. Its so much easier to blast away from the lights without revving the tits of it and it quickly gets up to top speed in 4th. So much nicer to ride. Don't have a dyno here in Singapore but Id estimate a good 20% more power over malossi and a damn site more torque. I'm very happy I made the change. By the way 2 caveats. 1) You will need to machine your case to fit the quattrini crank in as its wider than standard. 2) You cannot use the starter ring gear on your flywheel as it fouls the cylinder and in my case ate right through it and caused small holes. [/img] A bit of porting
A bit of welding to strengthen cases
a cautionary tale. You cannot use the starter ring gear on your PX or it will hole your cylinder like this.

Sounds impressive! What intake do you have on that? And where did you need to machine the case for the crank?

I wasn't there when my mech discovered the issue but he said the part I marked in red is wider than a normal crank see pic
I'm still using the standard 24/24 with a 155main jet for now (pending checking and changing - its only day 1) |

I assumed from the picture that it was a full circle crank.
You're sticking with autolube? Do you think it will be adequate? |

Here is a link to pictures of a German 244-build. Really nice way of milling the case for the crank.

Then there are those going in other directions but in my opinion everyone is entiteled to go his own way as long as it hurts noone else. |

I'm happy to move to a reed valve if it helps with my goals. 1) top speed 80mph (already achieved) 2) reliable 3) get to 80mph as quick as possible I'm not sure however that changing induction and carb is going to help me get to 80 much quicker than I already do. |

Has any ever tried to rig up auto lube for a Japanese side draft carb, many come with provisions for it. It would require an external metered oil pump, though.

So how did the scooter go with the BBS? Not very well obviously, but in what way? I would have thought that was an excellent match.

On GSF you can read about all kinds of modifications. 64 mm cranks, or using the 60 mm Quattrini crank with the M232 with spacers just like "we" do with Malossi and others. If your setup pulls like a train you could consider regearing some. Are you running std gearbox with those 12-inches? Not that I'd be unpleased with 120 kph as long as it is against the wind. |

It makes its power totally differently from Malossi that is for sure. I will be happy with 130kph and the same acceleration. Swapping back to modded SIP tonight but wont really get a chance to thrash it till probably Monday. I travel to work early in the morning and the roads are quiet enough to thrash up to full speed. 2 other guys that I know who get their maintenance done at the same garage as me are hitting 140+ with 232. I have 244. My gearing is 23 66 right now and I think once the exhaust is sorted will hit 130. Might need to change the timing a bit who knows. Without a dyno its a bit guessy |
