Banshee2105 Posted December 24, 2017 Author Report Share Posted December 24, 2017 Are those cylinders brand new oem, Niche, or used ? Just wondering the new looking paint caught my attention. They're new. Pretty sure they're Chinese as those cylinders and pistons came in a box together. And the pistons are cast. I didn't buy them, the guy I bought them gave them to me with the bikes when I bought them. Probably best to not use these pistons anyways.

I can tell you from personal experience be cautious of those cylinders. If they are Chinese the casting flaws will be insane and the chamfer on the ports will no doubt need attention.

Sent from my Pixel XL using Tapatalk Do not even attempt to attack those with a dremmel you’ll do more damage than good, I personally would check those cylinders out for burs and other casting defects take pics, those ports are calculated angles which require special equipment and the skill to use it to make repairs viable.

You mentioned Niche. Is that a good brand of cylinders? Based on the info that you gave me, I am not wanting to run these cylinders now.

Rigid_Banshee Posted December 24, 2017 Report Share Posted December 24, 2017 The Niche cylinders are ok to do stock setups imo. Never seen someone put them on a 4 mil but they might just work in the right hands. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
