2006> APRILIA RX 50 / SX 50 DESIGN FLAW FIXES

Here's a few fixes for some of the most annoying design flaws.

Cylinder head thermostat

Remove it, before it seizes shut.

Carburetor jetting issues

This post

Oil filler cap

OEM transmission oil filler plug gets in the way of carburetor float chambers, which makes sliding out the carb for jetting changes more of a chore.

Banana skin brake pedal replacement

Conti 1614TD0005 (knurled tip)

Coolant / oil leakage

Replace those metal washers.

Cylinder head and radiator thermoswitch plugs: M14 fiber washers.

Oil sump and clutch cover plugs: M10 fiber washers.

Ignition replacement

Only ground the blue wire if you want to restrict top speed.

Secure the rear fender by drilling straight through its mounting lug holes with a 5mm bit. Use 5x50mm screws, 5mm star washers, and nyloc nuts. Acerbis's enduro rear fender bag is a perfect fit for Hünersdorff's Fuel Friend 1L container.

5mm plastic straight piece between fuel tap - carburetor line. Refill container from the bike's tank using the manual tap.

SX 50 chain guard rubbing off tyre wall

Use spacers, or grind swing arm mounting lugs off. Single seat bikes don't require chain guards for public road use.

2006-2009 headlight straps

When they split, replace them with Polisport Halo straps.

Preventing a damaged battery

Without a lid, it bounces around. Use a few pieces of high density foam underneath, and around it.

RX 50 soft fork spring fix

Marzocchi forks: use SX 50 springs and preload spacers

Kayaba forks: use SX 50 springs

Alternatively one could just get a proper motorcycle. Try to avoid anything with multiple design flaws . This is my proper motorcycle.http://i.imgur.com/25POB07.jpg
