BS 175 and 200
« on: January 19, 2018, 02:15:18 PM »
These are my latest finds.! The Mach II I picked up in December - original owner with title - 3600 miles - stored for 30+ years. Doing the carbs now and just got air boots from Richard, otherwise its all there. The 175 came from VA and runs awesome. The TMX was another barn find for over 30 years it sat. Got it in December as well and new fuel, filter and lines and it fired up on 3rd kick!!

Wow! Very nice bikes.  BTW, your 175 has 200 cylinders on it (or it's a complete 200 engine).

Thanks - how do you tell the cylinders apart?

The two indentations in the 5th cylinder fin from the top are die ejection pin bosses.  The 200 cylinders have them, the 175's don't. Makes them easy to spot.
 You probably have a complete 200 engine as the 200 cylinders won't fit the 175 crankcase without some machine work to clear the larger 200 cylinder spigots.

The red 175 appears to have a 200 seat.
