I did this as a sort of custom, as I dont really like the original seats & rear fenders. I decided on the retro racer theme when I found out that these were a favourite with local racing enthusiasts. To the purists: yes I know it's technically not a 'Royal Enfield' (Constellation sticker on pedestrian slicer) but I took some liberties ok!

I think you did a nice job with it.

It looks like a fun bike.

What motor is that? How well does that 2 stroke run with a  megaphone exhaust?

That little bike is sweet as Pete, man! It reminds me of the stuff I used to make when I was younger ...... I'll BET that thing is more fun to ride than a red-head with half a bottle of wine in her ....  ;) Heeheehee!! Great job - I'd call it an Enfield on enthusiasm alone!

It's Enfield India's 1970's version of the Villiers 197cc motor (it runs a Villiers 197cc piston & has Villiers air cleaner & Villiers type 25 carb). It was developed out of Enfield's previous use of Villiers motors.
I think it runs a bit better with the cocktail shaker muffler. It has a baffle in the end of the header pipe, & 2 baffles towards the end of the muffler. So Im guessin somehow the whole expansion thing seems to happen in the tapered part of the muffler. The old Villiers 2 strokes on the 50's British bikes just used to have a basic peashooter exhaust !
The old enfield muffler is now sittin in my shed.

Carb is Villiers S25 type. Some of the ignition parts are generic British Lucas parts,(eg. Lucas switches) & some are Enfield India (eg. Minda ammeter) Overall, the bikes were a mix of Enfield's India's own design, Bullet 350 parts, generic parts used on other British lightweights, & Villiers parts.

no villiers had closed down in the uk by that time (mini bullet) and also had villiers (india) ,, somehow ???? enfield india found the money to design new crankcases for the old villiers engine and produce a more "streamlined" version , but you can still see the villiers heratige ?

I do see similarities. My Dot was a 1956? I think Greeves used the same engine?
