QUOTE(jaycee1 @ Aug 27 2024, 04:56 PM) Will be reaching the 30k schedule major maintenance with VC check in 3-4 months. Will know for sure if the cheese cam problem affects our bikes or not. So far no reports of cam failure on the 800nk and 800mt yet...so hopefully that issue has been addressed. Camshafts made of soft cheese continue to be an issue in KTMs, despite everything. I'm surprised nobody has floated the idea of using CFmoto camshafts in KTM's LC8C's valvetrain. If CFmoto punya lebih tahan, I wonder why that is. Separate production lines in Zhejiang? |

Dunno, mate. On the other hand MCN quoted Blaire Knight, a Senior Technical Officer at the University of Queensland, who experienced cam failure on his 790. After the engineer analysed his own camshaft, he proposed that the part itself exhibits insufficient hardness to be properly resilient. “We performed an Arc analysis on my cams and the carbon content was lower than I would’ve expected,” Knight said. “The Rockwell test (a test of metallic material hardness) came in at 51, when it should’ve been up at 58 to 60 to have any real resilience.” Wallahualam. |
