Wanted to buy a good Royal Enfield Bullet crankshaft, do not need flywheels, but require oil pump shaft with the crankshaft if available. Good used, or new if available.
Mine is a 1951 350cc Bullet, so the modern Indian Enfield parts are no good as they do not suit.
Price negotiable, I have other early Enfield parts as swaps (Excellent Camshafts etc..). My bike had a terminal conrod moment, so would like to rebuild with original parts if possible.

Hi there
While I don't have any parts for you, sorry I race Enfield's here in Japan and have a bit of experience with them
In my race bike I use a Carrillo rod and the floating bush , yes , the floating bush
The Carrillo rod is quite cheap as the standard rods are lm2 , read Swiss cheese ,,,,
Anyway must dash ..

Save yourself from eventual trouble and put a yamaha rod and big end in the thing....

Royal Enfield was one of the first bikes to have an aluminium rod.
An expert on them said this was the first time he had heard of a rod letting go on a 350cc Bullet, and Enfield has been around a while!
I think the chap I bought it off just had a dud rod in it, and his "restorer" may not have been everything he thought he was cracked up to be!

Well if the engine is kept as it was designed , and trust me Ive come along a few years later with computers and the original design , it bang on ( NO fat on the numbers )
The rod is LM2 and is fine for the original use , NOT fine for large 525 ad high comp bores
the Yamaha rod , WONT take a 525 piston for any length of time, ( a common mod for the Sr 400 is to use a 600 top the rod WILL fail in fatigue
Though IF you keep the piston weight down its fine for low comp ratio ( the cost of a carrillo is cheap, )
Still doesn’t help u , sorry , . but I love these engines to bit ,

ps who was the restorer the enfield community is small and we all know each other !!!

I would have to do some delving into paperwork to find out, the bike came from Masterton, and I bought it some years ago now. There are other tell tale aspects of the engine as we pulled it down that gave us suspicion that the "restoration" was a weak one, second hand parts put back in etc... we are doing a full top end replacement/restoration on it.
Don't believe the original work was done by an Enfield enthusiast by a long stretch! I loved the bike at the time, that day will come again I hope.

yes, strange as it seems , I like them as well , I dont know why !, the rocker blocks are a stop gap measure , the combustion chamber is horrible , the gearbox is from an old lathe,,,,,,,
but ...
and even the indian built ones have their place ,,,,
Good luck and p-hotos as he progresses !
