Guys im almost back in the vespa game, ive been busy building my new house, almost done and now i have to start gathering parts to build my 8" monster. Over the holidays i picked up a mint 1964 vbb everything there minus engine, perfect exactly what i wanted. Now the reason for posting is that i want to build a nice 2 up road machine, 90 km max speed, must be reliable,conservative on fuel and most important i want to keep the 8" wheels, it looks proper with them. So im calling on any p-series gurus out there on what my options are? because i have no idea what is anything lardy?? I can get my hands on 150 cases but which ones are good? what mods should i do? gearing, clutch? exhaust? etc... my computer is still down, but i took picks of when i got the bike and ill post them as soon as i get nestled in the nest.

I'd try to get ahold of a late 150 Super motor if I were you, fairly easy to swop out to Ducati electronic, maybe an iron Pinasco or a DR 177 , 200 24 SI carb and box etc. and a Sito + for a little bit more grunt about the thing. Could be slight clearance issues with the Sito if you start throwing it about but then, well, you just look like and utter cunt doing that on 8" rims anyway.

To be honest I'd lose the 8" wheels especially if your gonna be going 2 up on it. Plus you will have more engine options. A standard px 200 engine will be fast enough and very reliable and you'll have 12v electrics, so brighter headlamp.
I'll be doing something similar as soon as I've sourced a decent oldie frame so looking forward to this thread

I can respect wanting to keep the 8 inch wheels...  Heidenau makes an 8 inch tire that is rated to 80+ mph. I have I installed a bunch of them & I likes 'em. Do take a look at the uprated front spring for the suspension. The BGM dampeners have been a nice upgrade as well. If you decide to keep the 150 motor as a base to start from, there are quite a few kits to choose from cylinder wise. I've been eyeing some of the aluminium ones, myself. The older motors have a thinner taper crank, so a lot of people lean toward the post '78 motors with a P style crank when thinking of applying more power. Lighter-flywheeled ignition kits might negate that issue, though... 200 motors have gotten a little more sparse, but definitely a score (displacement!) for those old chassis'. Clearance for a big ol' expansion chamber is not so great, but if you're thinking of a touring setup, the SIP road exhaust with the dual outlet has been pretty good to more than a few of the locals out here. Not mind blowing performance, but has good clearance & breathes well enough for what most of them want. |
