Is it possible to delite the compensator for o sprocket?

 

If you mean run a solid sprocket yes you can. Why ?

 

Just keep in mind that the comp is in place, to soften the engine pulses to the trans gears.
Depending on the amount of power you are making, if you do delete the comp, may have to go to a stronger trans, so your not busting gears.
Myself, just too easy to swap comp wave springs to add more tension if needed if your getting a lot of comp noise, to leave it in play to help protect the trans. Also, there is the latest gens of comps, that oil a lot better to keep the springs from wearing out so fast.

Hence most comp eliminator sprockets go for hundreds of dollars, while you can rebuild a comp with new wave washers (if that is just the problem on it) for about $40 instead.

 

More about reducing shock to the flywheels so they don't scissor on you.

 

Check crankshaft run out as well. I put a Dark Horse Motor Sprocket comp delete on my fast bagger, and factory recommendation was no more than .0008 run out if I remember right. Dano mentioned busting gears. You can bust other important **** as well with excessive run out and no comp.

I would have to ask Dan, but I imagine run out on Shovel era bikes were hit and miss, because 30 yrs later Harley had the same problems.

 

Early evo's and back have 5 PC flywheels, it's involved getting the 2 halves true then mating them with the rod set and it all running true to .002" or less at closest point to wheel per shaft. Pain but the up side is if done correctly they don't scissor like late models do.

And yeah it could be real hit & miss out of the factory those days.

I had a shovelhead chopper and it had a gear instead of the compensator. Ran well never a problem,just looking for less maint.thanks for the info.

 

Older bikes had better primary ratios and less horsepower so tweaking the crank wasn't as big an issue as it is with twinkies and later engines, don't hammer it you'll do fine.

 

​​​​​​FWIW, had a guy come by the shop last week with a '21 model year M8 bike. Said the only thing he'd done to it was a comp delete after the factory unit died at 2k miles.

Thought that was funny, how HD still fights those all those decades later.

In your case, if we're talking about a mostly stock Evo bike, the factory comp should be maintenance free and last about forever.
