What is the take on these from those who have used them. I am a fan of automatic anything so how long is it before you need adjustment? Does the spring have a little cushion to eliminate premature wear? Seems to me it would.
I do not think so. Not designed to do that. There is another mechanism inside the engine that may provide this function, not sure.
The next mod I am doing to my bike is the MCCT conversion. I am not doing it for any other reason than to hedge my bets against catastrophic failure of the cam chain tensioners.
There has been more than one post to this board describing an ACCT spring breaking. This minor part failure can cause the valves to kiss the piston heads. Very bad. By removing the spring from the system in favor of a more reliable technology (MCCT), the likelyhood of having this type of failure is reduced significantly.
I did try the $10 route for MCCT's. Got the bolts, locknuts, and neoprene washers. After putting one together and evaluating, I decided that though seemingly effective for some satisfied folks, it was still not a reliable fix for me. There was way too much play in the system, and I found that IMHO there was still a possibility for the same type failure as with the spring. I did ultimately buy the TOC MCCT's because they are designed exactly as I would want them to be designed, and not just band-aidish and weak. Sturdy and rock solid was the way to go for me.
I have not received them yet, but I think it will be a bonus not to have the interference with the coolant bottle as well.
Though the price for the TOC MCCT's may be higher than $10, my feeling is you get what you pay for. I don't feel bad at all about the $100 purchase.
