Pistons 836cc who makes em
« on: January 22, 2018, 03:56:19 PM »
Have piston set thought maybe 836cc Wiseco although not stamped with W. Pistons measure 2.557" or 64.9mm, rings measure 14.5mm (.57") top and 2nd while oil ring is 27mm or 1.07". I need new rings. Pistons have "K" stamped on top as well as EXH with arrow. full shirt and nice 5mm dome with 1.5mm squish

Your measurements are off by quite a bit. Wiseco 836 kits generally take an XC ring pack (unless they are ancient)

Cheap 836 rings here
https://www.ebay.co.uk/itm/Honda-CB750-Piston-Rings-x4-sets-836cc-65mm-1969-1976-Oversize-rings-Big-Bore-/382357385434?hash=item590646b0da
I have a set, ordered just for sure and low price.
Fits my old RC 836 (forged pistons), older RC cast delivered with old 1 oil ring and my Action Fours cast 836 I have read used CB350 twin 1mm over size rings.

yes, dream305. I thought he could be near you. He has sold these rings for a while. Last link outdated.

I bought a set of rings from him for my 836 with MTC pistons. I hope they are good as the price is quite cheap!
