I like that Hasting's break in method. Seems about right to me anyway. My method is to just ride the bike around town in a spirited fashion. Accelerate away from stops assertively, but nothing crazy. Progressively increase ring load as mileage accumulates. That's all. Keep it simple.

Also for me both rings are about the same color but the top one has a more shiny edge where it contacts with the bore, which is also different from what the manual says. The middle ring also seems to be a rectangular cross section and not tapered like the manual states, but i checked the old middle rings and they are also rectangular in cross section...
Other than that they have good end gap clearances in the bore.Last edited by Guest; 02-05-2016, 03:11 PM.

I've purchased the cruizinimage 850 standed rings and will be doing a full write up in the projects section soon,
I've measured the ring end gap and they are right on spec with new freshly honed 850 cylinder's. Time will tell this summer but I will be doing a proper break in and multiple compression test's / leak down test's to see how well they seal.
here is a listing for the 650 ones,
And yes, I know what you pay for compared to OEM rings

Will do Nessium ,
just an FYI for everyone, the cruizinimage rings were shipped from Japan, don't know if they were manufactured there,
but like I said,
You get what you pay for and I am well aware that I may have to replace them and purchase OEM if they do not seal, unfortunately I could not find any other aftermarket rings for the 850, ( NPR, Hastings, etc.) after searching the internet and settled on these ones.Last edited by Guest; 02-06-2016, 10:23 AM.

For 850 rings, I would imagine the Wiseco rings in the gs750-844cc kit may likely be the same spec, wouldn't they? Or are they different thicknesses etc?
One great thing NZ Ian aka 49er pointed out to me about the 850 (and all 1st gen/2v GS550/650/750/850), the design really helps prolong bore&piston life:

I would imagine you could potentially get much much longer life/higher mileage out of these vs a long stroke GS1000 if you were doing a lot of long haul trips and keeping up on proper maintenance, and always letting the bike warm up properly before hammering it. The GS850 does have a reputation as a bulletproof touring bike...'77 GS750 920cc heavily modded

As far as the wiseco 850 rings being used instead of OEM or cheap aftermarket Cruizinimage ones, pretty sure the the piston ring lands would be thicker / deeper and different to help with the increased compression ratio the wiseco 844 BB kit.Last edited by Guest; 02-06-2016, 12:12 PM.

I just measured the 850 crusinimage rings, Basscliff doesn't seem to have a 2v 850 service manual that I can compare my findings too? Anyone have a PDF. manual or a link to one?
Cheers

Just checked, the 750 FSM doesn't give detailed specs for the rings, I have a Clymer manual that I can compare their specs to

Crusinimage ebay 850 rings
1st and 2nd compression ring,
Thickness
both 0.046" or 1.18mm
End gaps,
both 0.015" or 0.381mm
Width,
1st ring 0.1095" or 2.78mm
2nd ring 0.107" or 2.76mm
These measurement's were consistent with all 4 ring sets and were all measured in the same freshly de-glazed 850 cylinder, (850 cylinder professionally deglazed on a sunnen honing machine) and are taken around 10mm from bottom of the cylinder,
When I get my other parts back from the machine shop I will be doing a thorough Thread in the Projects section, and will document everything
Please note that the ring width is thicker and I do not have specs for the 850, I do not have a bore gauge to have precise measurement's of the bore and I neither have feeler gauges thin enough to measure Ring to Groove Clearance,
I will ask my machinist to take these measurements next time I'm there.Last edited by Guest; 02-06-2016, 01:59 PM.
