Hello everyone,
I've encountered a problem recently. To control the compression ratio (90mm x 92mm = 585cc), I used a 2.36mm head gasket. Consequently, I purchased a two-section extended cam chain from KEDO. Everything seemed to be in order, but I observed that the cam chain tensioner is insufficient in length due to the chain's two-section extension.
I've pondered over this issue, and though there are numerous ways to lengthen the tensioner, it doesn't feel right to me. My concern is that the tensioner length and the force applied by the internal spring should be "fixed" values. Meaning, irrespective of whether the chain is extended or not, it should adhere to a specific force, and the tensioner's alignment point must be in the proper position. In other words, the end of the inner push rod should line up with the end of the M10 screw on the tensioner. If I extend the inner push rod in any way, the tensioner's force may not be accurately set. Can anyone confirm whether my understanding is correct?
If this understanding is indeed fixed, then presumably, I'll have only a bit of thread left to secure the outer nut, which could pose a problem. Moreover, due to the extended cam chain, the tensioner will need to exert more force over a greater distance, which could increase the cam chain's overall curvature. Should I be concerned about this?
I hope someone can help me dispel these uncertainties. I appreciate any assistance you can provide. Thank you.
