Anyone here ever have the rotating assemblies static and dynamic balanced? Do you feel that it was worth it? Did you notice a difference? I'm going to have this done to my bike and was curious if anyone else has done this?

Hi,
haven`t done this to my bike, two guys I somewhat know did.
One dragster-shop I know is doing such work on a regular basis.
It`s a german site which doesn`t matter cause the terms should be known to you. Just to get an idea: http://www.kramermis.de
Anyway ,all three of them talked about stroked EVO`s, only.
88cu and up.
One used an S&S crankshaft-kit with JE-Pistons, the other Wiseco (???)

However all (including one pre-evo specialist) will balance it 60%.
Costs: static ~ $80 plus 2 hrs
dynamic: ~ $250 + 2 hrs

Apparantly, it makes sense to stroked bikes and for cranks which are ill-balanced by the factory and last but not least for cranks with foreign company conrods and pistons (such as above: S&S crank plus JE-Pistons).

Did they notice a difference ?
"und ob !" replied one (which means 'of course' )
The pre-evo specialist explained that the shovel longevity improves a-lot even with stock engines, however he recommeded it for stroked engines in particular.

ray.

in theory it frees up horsepower,reduces parasitic losses.

I read an article a few years back about a shop that took a stock Evo Lowrider and did minor modifcations to the engine(carb rejet, cam, exhaust) when they balanced the rotating assembly. When they but the bike back on the dyno, it was pushing about 100hp. My goal with the mods that I'm doing to my bike is at least the 100hp mark before the nitrous. I figured that if I'm going to start creating that much hp, I might as well check the bearings and tolerances in the bottom end and have the assembly balanced in hopes of making the engine more reliable and better in performance.
