Chugging around Chiang Saen Lake on a classic BSA

[ianyonok]

This bike is a 1952 BSA M33, that I restored a couple of years ago.
But I didn't split the cases. After 2,000 miles, the big end failed and the engine stopped dead. Engine apart, I could see the Burmese installed big end rollers were stainless steel instead of hardened steel and the journal was mishapen.
New big end in from Alpha Bearings ( been making these big end bearings for 80 years) and we're back on the road.... Fantastic.

It’s always interesting to hear about the challenges with vintage bikes, especially with parts like big-end bearings. Sounds like the switch to Alpha Bearings made a difference.
