I'm a newer scooter owner, I bought a 2004 Chinese scooter with a two stroke 50cc minarelli motor. I replaced the exhaust with an expansion chamber, then put in a 70cc BBK, replaced the carburetor and adjusted the main jet. Working on tuning the new Malossi variator I installed, and dialing in the carburetor. My 0-35 times have gone from 13 seconds to as low as 5.90 seconds, usually around 8.0 seconds. Need to dial the variator in better. I can now reach 50 mph using a gps. Cooler weather is slowing me down at the moment.
I came across a 2005 PX150 Vespa with about 5000 miles, runs needs minor work from what I can tell. Thinking this could be fun to ride and tinker on next spring, looks to be a two stroke from what I have read. Anything I should be looking for mechanically that is a common issue? I can see some oil on the right side on the case by the rear tire in pictures. Going to go look at it in person.
Would this be a good scooter to ride a county road at 55-60mph? I see upper end 177cc kits, are they about the same work as a minarelli top end to replace? From what I have read it looks like a good performance gain. Guessing I would do exhaust, then bbk, then carburetor. Also saw a few sports kits that were all inclusive that looked interesting, and less work than mixing and matching.
I have a full size 2017 Indian Chieftain that I use for any longer rides. Might use the Deal a to ride at 55-60mph and ride it 10 miles to work on a two lane county road.
