Some idiot broke an oild ring whilst fitting the barrels back to my 916 
Dont really want to buy a new set at £145 plus Vat so if anyone can help 
I’ll have a dig around for you chap but…
TBH I usually throw them away as I wouldn’t dream of building a motor using 2nd hand rings.
They cost almost nothing when compared to the cost of a “Pukka” top end rebuild/re-fresh, if you factor in the wasted gaskets if they aren’t up to the job.
…and that’s without the extra effort of stripping the motor again.
