Sleeving Concentrics?

Does anyone machine worn Amal Concentrics and install sleeved slides? Bruce Chessell has stopped doing them

I’d imagine the price couldn’t be too far off a set of new premiers- they’re the business! My commando and triumphs love em- what was the going rate for a sleeve/rebuild?

If google returns nothing, I doubt anyone is doing it anymore.

Doesn't work all that well unless chromed sleeves are used. I had it done long ago by Mike Gaylord Products with steel sleeves and it didn't work well for long. Either that or I just got tired of dealing with Amals. That should get somebody to say they've been using sleeved Amals for 400,000 miles without any issues.

If you think the carburetor bores are still roundish, eurojamb sells chromed slides that should work better than steel sleeved slides.

I still have the sleeved Amals in a box. Pack rat that I am. Also confident the guy that did them is not capable of or interested in doing that kind of work anymore.

Extract from Brit Biker Forum:

"Andy Hardan runs/owns/ took over ... Lund-machine service years ago , and operated out of Seattle ( Snohomish )
... still offering resleeving service , but now out of Texas .
He is now located in Springtown Texas USA and better than ever. Phone Andy at 206 799 1240. He is retired and still does mono blocks and concentrics. I have had him do over a dozen carbs in the last 20 years. Top notch service. Quick turn around too."

What’s the price? I’ve got literally a milk crate full of dead amals- mite be worth rethinking the strategy if it’s cheap!
