OK I have a lightened Flywheel, been itchen to try,but every time I go to my shop,or chat with a builder they say WHY???? your going to loose inertia only hillshooters and drag racers need them, you will betrying to keep it revved out all the time.

 

Just imagine how much stress 3/4th of a lb takes off the bottom and in general. Let alone reving faster. I have a full weight flywheel though. I had a light one on the stockbore. I should dyno my bike before and after the flywheel change. Or maybe someone else should.jmo

 

They obviously don't understand how over weight the DS flywheel is. They should all be 4.5 lbs instead of 7 lbs. They work much better and the rev speed is noticable.

 

ERBE,
I trail ride and dune ride mostly, hill shoot just for fun now and then. I put a lighter flywheel on mine. Just running through the gears is fun with a quicker reving engine

I think I lost a little bit on my launch for hill shooting with the lighter flywheel, but make it up once I'm off the line. I also think its a little easier on my drive line, from the crank to the clutch all the way to the rear sprocket as when I dump the clutch I have less inertia hitting it all.

My build is very mild, and I notice it having a sharper throttle response with the lighter flywheel, and in some ways its a little harder to ride on loose fire roads since it revs faster and spins more. Which to be honest is kinda a cool problem to have.

I notice no loss in just cruising ability, luggin, or idling. I would never go back.

Heck yes on the flywheel. Them things are boat anchors! If you liked how adding a 520 conversion, or lightened hubs, or triple buffs, or anything of that nature. You will like the flywheel lightenened. It should be mandatory on all builds.

Any Glamis Duners over 240LBS riding with a lightened flywheel?

 

I had the lightened flywheel on my DS and it was a duner.

Put it on.

WOW - We all agree on something. . . refreshing. . .

Quick - get AZ in here too and while you're at it Gary.

I think everyone will agree the stocker puts more stress on the engine that isn't needed.

 

First ride report on lightened flywheel

Just got back from florence and after some killer rides on just about every type of dune terrain and pass after pass on the hill. I can tell you that there's very little down side of a lighten flywheel. It revs way faster, I didnt notice any loss of bottom end and it would still tractor out of just about anything. The only slight difference was when decending a hill using compression to hold you back but it was slight. It will pull rpms very quickly so shifting is more. My understanding is that it will also save on your bearings and other internals which means longer engine life. Which is a good thing!

 

Well the Shop putting my cams in stated that "big guys" need that inertia specialy in Glamis when going down long dune faces or playing in the chop, Im sure you guys have a snappy motors with a lighten flywheel in the Oregon dunes,but are any of you guys over 250LBS riding with a lightened flywheel out here in Glamis?
