 ====== 3D-printng Honda motorcycle spare parts ======
+**Creating 3D models of discontinued parts**
 I own an **Honda NTV650 Revere**, year 1991, and I still use it regularly after 33 years and **254.000 km**. The bike has been kept in perfect working order for all these years thanks to the availability of original spare parts, a true Honda excellence.

-The original lever does not fit the non-original petcock, because it interferes with the metal body.
+The original lever does not fit the non-original petcock, because it interferes with the metal body. So **I drew in CAD a modified lever**, which will stay in the correct position once mounted on a short-pin petcock. Here you can find two 3D projects: one is like the original part, the other does fit a 5 mm pin petcock.

 :!: **WARNING**: The original lever have a **metal inner core**; my project features a **7.0 mm inner hole**, so you have to fit a piece of metal tube in it, see the picture:

-This is a slightly modified project, designed to fit petcocks with a **5 mm long pin**. Generally these non original petcocks have the pin smaller: a square section of **7.60 x 7.60 mm** instead of 7.90 x 7.90 mm.
