Hi all
The company I have been using for the last few years recently closed the doors. Falicon cranks

I was recommended to call Crankworks - They come with a good reputation, but they do not service 1 piece cranks like out brit bikes

I am hoping you guys have a recommendation from experience. I am very much concerned with your experience as I have installed cranks that were "balanced" to have a machine that better resembles a jackhammer.

Thank you!

Revco in Long Beach. I had to lightly assemble and true my b50 crank for balancing, then disassemble afterwards to install the rod.

Thanks for the tip

Here are the 2 places I have narrowed it down to:

Marine crankshaft - Knows and is very familiar with Brits and motorcycle performance

Kenmonth Machine - since 1932 family owned and also familiar with Brits - great pricing and super close to me so I can walk in for a verification Shop looks well established and clean.

Both these guys specialize in forged 1 piece cranks. It was very interesting how many places I called (38 total across the US) that do not work on 1 piece cranks regardless of make.

You are in luck Nick. A great place to use is: http://www.lindskog.com/

Lindskog balances all sorts of things but they do have an in house specialist that does motorcycle cranks. They are in Boxborough, MA.

I literally picked up my BSA crank from Lindskog this morning. Nice shop, easy to deal with.

Epic! Thank's! Was it an A-65 crank? What was the "balance factor"?

Does Jaye have the equipment? I've spoken to him and got the impression he was not interested in taking on my BSA machine work, ie semi-retired.
Had a nice long chat though.

Most important thing to balance out is the rocking couple, the factor is less important, although mine is 62% which i mentioned I beleive the factory used 64%. mine was done to be good at 4500 rpms, its good right the way through tbh.

FYI, Britech does nothing in house, like machining, balancing, boring, etc. All gets farmed out to others to do. Not a bad business model as a facilitator, but for you, going straight to Lindskog would be a faster, cheaper and better option. That way you actually know who did the work.

How about a local (Eastern MA) machinist for BSA and Triumph? Cylinder boring, bearing line bore, crank grinding, etc.

I just took it all to Don Hutchinson in Wakefield. He did the timing bush in house but sent out the head and cylinder/pistons to an outside machinist. Took about 4 months to get it all done, though.

Advanced Engine Rebuilding-Wareham, Ma

This guy has a good reputation for auto engine rebuilding, and I've heard that he does motorcycles as well, but you'd have to call him to verify that. Let me know if you do, I might need some engine work done on my T140 this winter
