Default Cooling fin Dampers

I just got done putting some rubber dampers in between the cooling fins on my motor, and man did it almost get rid of all the reverberation,vibration,harmonics,whatever you want to call it....It`s alot more smoother,quiter,ec.t ect.....I had some clear hose laying around and just squeezed in together and pushed it into the cooling fins and cut off the extra sticking out...1" peices all in the cyl.`s fins and head....No melting or falling out....I think it`s worth doing,JMO....

I used the clear tubing also, but I put it in every other opening, as I was afraid of overheating. Works very well....

Hey either way I was surprised at the result....Night and day difference don`t you think????I still have plenty of openings to get the cooling effect going....

You know I have always wondered about rubberized under coating. Especially if you wanted your motor black.

Do you think it would restrict the cooling too much?

I often thought about the rubber coating too, but what about using it on the inside of the cover instead?

I put fin dampers on mine, and honestly it didn't sound any different.

I may try it again, just to see.......or rather hear....

I put rubberized undercoat on an oil pan on a Bronco and it just burned off. I would think it would do the same on these motors.

I wold think the coatings would have an affect on the cooling....No way for it to dissapate.....I actually drilled holes in my outer covers to let excess heat get out quicker(see pictures in picture thread)....Every cover on my bike is drilled with holes for cooling...Here in FL. it gets pretty hot.....But it does let more noise out of the motor,like the clutch side....I just use my air hose to blow out any dirt ....
