I'm pretty much settled on getting an aluminium Pinasco 177 kit this winter, in advance of some long-distance touring during rally season next year.

Anyone here have any experience with the Pinasco kit as a bolt-on? I'm mostly looking for an increase in uphill torque, but am also curious about the kind of speed gains I might see. I know the porting and gearing becomes a limiting factor, but at this point I'm just going to bolt-on, along with a Sito+ and 24/24 carb.

I have one on my Sprint project bike motor, which was a P125 motor. I don't have any first hand knowledge yet though, so I'll be interested to hear too.

Yeah, I'm still undecided on whether to rebuild the old 125 motor and port it, or to bolt-on to the new 150.

Advantages to the 150 include electronic ignition, cosa clutch, and EFL gears.

Advantages to the old 125 include not giving a fuck about blowing it up.

Decisions, decisions...

I bought the pinasco 177 for the same reason and application, I will be using, for now, the stock SI 20/20 with 108 jet and the already installed sito plus exhaust. I have no experience when it come to performance upgrades; however, during my research and reads, it's an excellent, high quality product, and if it is keep as a bolt on, it is very realible and lasting; It has a wider power band and increase torque but looses at the top end power and speed compare to the mally and polini. Mally and Polini focus on top end power and other engine mods are recommended. Top speed for the Pinasco 177, at wide open throttle, on a sound PX motor is claimed at 125 km/h or 77mph. I think that claim seems too high for me considering that I am 330lbs. If I can get great torque and power at lower end and especially at the most useable mid range for city traffic and hills; and be able to cruise at 100 km or 65mph without any over heating, I will be one happy camper. I believe the Pinasco 177 Aluminium can do that and thats why I bought and going to install it on my 05 PX 150 . Now I have discovered that they brought back an improved 177 cast iron. So what now???

Best regards

Go with the aluminium, but you won't cruise at 65, especially at your weight. I'm 280 lbs and could only get 60mph out of basically the same setup as yours. It does cruise really well at 50-55 though and has much better acceleration than stock.

If it were me, i'd put it on the 125 and do it right. You've got your runner right now ... so use your bench engine and really MATCH THE PORTS ... and do it up proper. You'll be happier in the end, i think ...as you'll have 2 doable engines you can readily swap out.

I installed the Pinasco 177 on my PX125e and have out roughly 500kms on it thus far. The kit has performed very well for the most part and the torque increase (especially up-hills) is a HUGE improvement. I haven't really had it flat out, but the top speed, and crusiing speed has definately increased.

Currently Im running this kit in conjunction with a Sito+ exhaust. I may install a real expansion chamber type exhaust in the future and possibly install a taller 4th gear if possible.
