Valves for 1920's v twin

[winchboy]

Thinwall sleeves are a quick,cheap and easy way to reclaim a guide, comes as a kit. Ream out existing guide, drive in new sleeve, stuff a bearing down through the new sleeve which dresses the new sleeve hard into the old guide and ream to size.

Or if it’s not to worn you can knurl a guide which brings it back to size, some believe this is better than a new guide because it retains the oil.

Cheers Bob that's great, seems the best option at the moment. Had no idea about dressing the liner with a ball bearing.

Something over 100 tears old that survived the scrap drives of 2 world wars that deserves to be repaired and allowed to be as it was born, a bike from 1922.
Unless of course it's a Chopper and effectively already destroyed.

I should add I'm not biased in any way at all. Honest.

Not a bike its a car, I've a couple of the engines so one can be left original, the other can be played about with as you'd never probably never find parts to build another car up. It's amazing what survived the war effort and what still turns up in sheds. I'm a big fan of any v twin shoe horned into places they shouldn't be

Paging @8ob to the valve guide liner phone.

Link!

You only really need the liners, the bearing and reamers would be available here. Cant believe how much that kit has increased in cost, think I paid about £250 for the whole shooting match.
