I think I caught my Cross Performance just in time. Only about 15 tanks of 40/1 tuned at 13500 rpm.
A lot of plating came of on exhaust side. TAUGHTS anyone. Bad photo but there's a lot missing.

I do not wish to have a replacement sent just wondering if I did anything wrong with tuning /oil mix. bevels looked good to me on this one. I know aftermarket is hit and miss. some good some not so goodI think before using AM cylinders one must be sure he has a competent knowledge of what to look for and what corrections need to be made before insatlling them so they run right. They can be a decent cheap option to the right people who can for see problems. But nothing compares to OEM for quality and service life. I don't want to judge the OP's intentions starting this thread, its chainsaw related & he's asking for advice/help. But in the back of my small brain I wonder if threads like this are a concocted ploy to have a new replacement sent to them at no cost. It happens a bit and I'd hate to see the Gentleman's generosity to be mistaken for stupidity.
No. That's a defective product.Ijust wondering if I did anything wrong with tuning /oil mix.
No. That's a defective product.
I guess my question is, would beveling the ports prevent this, or is it a defect that the user can not address???
Sorry me bad OEM/Stihlome? that a new brand?
Wouldn't matter. The plating is still defective. It should never just flake off like that.I'll bet getting the plating correct around such angles as those bevels is trixy. ...then when the hone goes through there to do the final polishup....maybe just the very edge is too thin....and prone to breakage.
I'll bet this would have been fine if that bevel wasn't plated.
