Will power pulley like the one's from perrin screw up my 992.5rs.

Not to sound mean but only people with experiance respond. I'm tired of reading about people that have read this or that.

Any help would be great,thanks.

 

I'm not sure what qualifies as experience. But two of my friends have/had them. One had underdrives, one has lightend. Neither have ever had any problems. Both recommend I get them, which I intend to.

i have lightened pulleys. they havent harmed my engine in about 10k. that is all i can tell you from real life experiance.

now from what ive heard-dont get underdrive, they are not worth the trouble they cause in the long run. any lightened crank pulley, wether underdrive or not, will void your warranty though, and possibly cause more vibration and wear out the bearings prematurely

 

I'm sure you've heard the arguments in favor of pulleys. Here's one against it. Draw your own conclusions.

 

I had one on my 99RS for a little over 65K miles with no ill effects.
