Cool Rocker Lockers

Has anyone tried out Rocker Lockers on rocker arm mounting bolts ? Have heard good things about these quieting down upper rocker noise. Saw you tube vid that audio before n after install and was wondering if there really was that much difference. This quieted upper end noise fairly well...wanted to know if there were any personal experience's out there that can vogue for the repair or performance ... Thanks

I know of several respected engine builders that use them. Don't cost a lot, so they are affordable insurance for a quietER top end. Note: Asian marketing has entered this market with cheap, irregular products.

I ride like an old guy that wants to get older.

We were using a different method to hold the shaft, but those brass shims seem to help in certain applications.

No secret whatsoever, I just do not sit and ride this message board all day as my business duties require my attention....
Now that is addressed, we used to drill/tap into the rocker support plate with a 10-32 set screw, and secure the shaft.
The shim is a quicker approach.

Good results from them here.

While you're in there, you may want to shim the shaft ends also. There tends to be a lot of play there allowing the rocker arms to move too far laterally, also attributing to top end "rattle".

sometimes hearing disabilities can be a blessing. i just ride with my hearing aids turned off. i do turn them on to listen for lifter, piston, lower end and primery noise once in a while. i prefer the hearing aid off settings though, i can still hear the exhaust, man what a quiet engine.
