Hi all, although I haven't made a start on building the engine yet I thought It would be worth starting the thread and detailing what I have got so far - im planning on starting the build within the next 2 weeks. I have started out with a set of motovespa pk75 cases - I bought these brand new, they have the small cylinder spigot which will need enlarging. I also have:- - Parmakit WForce 144 SP09 Evo rotary induction cylinder kit
- Falc VNAS0002 51mm stroke, 105mm conrod crank shaft
- Falc intake manifold to take VHSB carb
- Vespatronic ignition and flywheel
- New original piaggio shaft and gears
- DRT selector
- DRT runner tree
- XL2 clutch cover plate
- XL2 clutch with newfren carbon clutch plates
- Premium SIP gasket set
- New original kickstart quadrant gear and spring
I haven't yet ordered an exhaust or carb however im 99% sure I will want "big bertha" and a 34mm VHSB Dellorto - any comments would be appreciated.
I would also like to take the opportunity to thank Wayne @ wolfe performance for his support and great customer care while ordering parts.
I plan to take plenty of pics as im keen on helping others and hopefully creating a thread that should help others pluck up the courage and spend a small fortune on their smallframe.
My main aim is to have a fast road going scoot - I don't intend to sprint or race but I would like to put up a good fight with my brothers - Pedro who has a malossi kitted Cosa 210 and Antonio who has SIL GP rapido 225 tweaked by AF.

Have you thought about going for the W-Force direct induction kit? Possibly with a 54mm stroke crank? The Falc crank definitely is very good, on a roadgoing scooter there are cheaper alternative which work though.

not thought about it - what's the main benefit of direct induction kit compared to rotary?

not thought about it - what's the main benefit of direct induction kit compared to rotary? Less work as you won't have to bother touching the inlet plus the manifold comes with the kit. Also, you'll need a beefier clutch than an xl2 one to cope with the power ie: falc, hartz, DRT, etc... |

Interesting combination. I would have looked at Amazombi's option as more favourable to be honest although were all different. Good look with your build, I'm sure you'll enjoy doing it. Is the Xl2 cover the Sip remade one? Hopefully you have an original and not the afore mentioned. Mark  Look forward to seeing your updates. |

Ive had the SP09 rotary and sold it and now got it back to have another go at it. I have the W Force water cooled one and on the road its sound to ride so I presume the SP09 will be the same. Going back to the older SP09 now that was a bastard for the road which is why im going to use it as a sprint engine when I get round to doing it. For what its worth I love the Parmas full stop and built loads of the 130s and to be honest they will be more than a match for the malossi and rapido brothers.

That's exactly it. I'm a fan of rotary engines myself, but if easy power is what you're after the direct induction kits are the way to go because the inlet tract has been sorted in the factory alreaday. Use a 54 mm crank with a 105mm conrod and you won't even have to machine or weld the crankcase because most of the transfer porting can then be done in the packing plate. And yes, it's going to eat that Malossi and the Rapido for breakfast You may have to think of a place to fit a toilett roll or something on your scooter to help out your brothers when they need something to wipe off their tears. |

Sounds like I missed a trick with direct induction however if its main advantage is less work then im not too fussed about that - im keen on learning about the rotary induction at the same time so this may also help? what are my chances of hitting 20hp with this set up? |

Hi Mark, thank for the comments, the XL2 cover is an original one so hopefully should be fine. |

Your chances are good, I'd say. A humble Mazzuchelli Race crank plus a bit of work on the crank would do the job nicely, no need to go for the Falc crank really. I'd say 20 to possibly 25ish is doable. With the direct reed it's 25 pretty much all the time, provided you jetting and ignition is as it should be. With a bit of work on the exhaust port this would go up quite a bit |

Hi Mark, thank for the comments, the XL2 cover is an original one so hopefully should be fine. Great stuff, the Sip ones are a bit hit and miss by all accounts. I have both genuine and remade although I am reluctant to use the Sip one at the moment. |

have made slow progress - while I was waiting for some dummy bearings I decided to build up the gears. Box of goodies to start with:-  I followed the sticky that jonnys put together, another great example of a great forum - made the job a doddle!! Started by putting the DRT selector on the shaft, used the uprated spring and some new balls! Its feels very tight now, cant wait to feel the difference.  Then placed the gears on the shaft with some shims untill i got it as per sticky thread  |
