I need to call on your wisdom again my friend, today i bought 3 50s vespas at auction for about 2500 australian dollars (includes tax and freight etc) And i wish to sell two of them to fund building the third into the best smallframe i can. What i want to know from you is what you think would be the best and easiest modifications to do to the other two to improve performance (maybe 90kph) and handling yet keeping it as reliable as possible, and also to do this as cheaply as possible. I am wanting to build the scooters i am selling into bikes fast enough that i can sell to non scooterists as daily commuters, what cylinder kit and carb combinations do you recommend? Also will a pk electronic ignition statoe and flywheel fit a 50s at all? As i wish to convert these to electronic ignition for reliability. I am buying a malossi smallframe reed valve kit for 50 australian dollars
Is this setup any good for the faster scoot i want to build?
If you could give me a list of components i will need that would be great. So far i am thinking for the bikes i wish to sell maybe a cylinder kit (pretty fast but must be cheap and reliable) A repro ss90 exhaust (or expansion chamber if they are heaps better) Some kind of electronic ignition kit, A larger carb (what size do you recommend?) A new crank (again what is the largest stroke i can go to in a 50s?) And an uprated primary gear kit.
Of the three bikes, one has 330 km on the clock, another 8000 and the third 3000 would i need to replace all bearings in each or could i get away with just replacing the crank bearings (dodgy i know but im trying to save some dollars)
And lastly for my own smallframe i was thinking of using zirri parts, do you have any idea on prices and specs on these? I hear people talking about them alot but i dont know much about them.
Once again i gotta say that it is great having someone as knowledgable as you to ask this stuff to, as hear in australia there arent that many smallframes around let alone tuned ones.
