2000 Aprilia RS50

Motocicleta Italiano

My weedwacker with wheels.  Don't you just love the smell of castor oil in the morning? With the big bore cylinder kit and larger carburetor fitted I need to supplement the fixed output of the standard oil injection pump.  So I add some Maxima Castor 927 pre-mix oil to the gas tank at 100:1 for the aromatic qualities and to keep my motor happy.

I was obsessed with these bikes while in college but I was too poor to afford one back then.  They're considered learner bikes for rich teenage kids in Europe who dream of becoming Valentino Rossi.  

My sweet wife gave this to me as a birthday / wedding anniversary gift in September 2013.  It's great for short rides around the neighborhood on early Sunday mornings.

Parts you need to modify to convert your Mikuni TM24 to cable actuated starter enrichment (choke)

In the beginning… When I first got the Aprilia, starting the bike with a cold engine would go something like this: Kickstand up. Ignition key on. Shift gearbox to neutral. Kill switch set to Run. Snake right hand between plastic bodywork and aluminum frame. Fumble around blindly as I awkwardly reach for the Mikuni TM24 carburetor plunger mechanism and pull up to activate the starter enrichment circuit (choke). Press starter button.
