Flywheel takeoff - what's it cost?
Don't know much about flywheels, but want to do the mod after reading about it. Anyone know how much it might cost to have a shop get the flywheel out / put the lighter one in?
Was thinking I'd send to ducshop.
Is it difficult to do on your own? I've been known to put holes in walls over changing lightbulbs - on house lights - so for me to attempt it'd have to be super easy.

Should be a 2hr job at your dealer, or you could have Dave do it for about $800.00  Aloha Alex

Ducshop is a great place, but you're considering sending your bike across the country to have a shop install a flywheel? so that's $1000 to ship your bike, plus 3-4 hours of labor at $100... $1500 install for a $75 flywheel? 
Almost any shop can do the job, or a friend with some tools... need a case removal tool, some good wrenches, loctite red, loctite blue and not too much else.... we had to heat up the nut that was holding the flywheel as it had some strong loctite on it, but otherwise a relatively easy job.

Why do you want to do this? Because others are doing it?
What type of riding do you do and where do you do it?
Are you tracking the Hyper and/or racing?
IMO, this is only a benefit if you are tracking/racing the bike as you will not see any benefit for normal road riding. The mod can actually be a negative as it will require you to shift more often and the decreases the ability to ride a gear high without lugging the engine.

I've never needed to shift more often after installing a lightweight flywheel.
My SS, ST2, and both LeMans all have lightweight Ergal flywheels, no downside at all.

Because there are no downsides (lightened 2lb stock flywheel). Only +'s Aloha Alex

Your profile says Portland Oregon. Why don't you take it to Moto Corsa or Daric at Chesire Motorsports? It is a pretty simple job for a shop and I know both of these shops have done a zillion of these.

Maybe it is just me but I did this mod on the Hyper and I found that when riding in town, the bike lugged more when I tried to ride a gear high or at lower speeds. To compensate, I had to shift down and keep the revs up a bit more.
For example, if I was cruising around in town, lets say in 3rd and slowing for traffic/corner, the engine wouldn't lug and I could avoid shifting in stock form. With the lighter flywheel, I would have to shift down and back up.
Not really an issue on the open road but was a bit annoying

the only downfall I've seen is unexpected wheelies from the power coming on sooner. Some could argue that unexpected wheelies isn't a negative either.
I wouldn't attempt this job if you aren't a fairly competent mechanic. You need an impact wrench and some other tools to do the job right.
