So I work at the Parts counter of GNGonzales, one of the biggest, and oldest Honda dealers in the Southern United States. Last week, I discovered a shelf of older Honda parts, and we're looking to sell some off! We have original pistons and ring sets all brand new in the old red/white Honda boxes, PM me or email me at
dylanmacon@gmail.com and I can check on any old part numbers you've got.
We also have engine covers, cylinder heads, all kinds of things. Ask me, and I'll get back to you same day in emails. Our crown jewel is a Honda CA72/CB72 cylinder that should also fit a CL72, part number is 12100-262-000. It's the last brand new one in existence as far as I can tell. Email me and we'll get you sorted out, I can also email you pictures before we get it shipped!
